How Do You Create a Digital Twin – 5 Things to Know

The Digital Twin is reminiscent of the early days of the personal computer in many ways. Initially, creating a digital twin required excessive computing power and multiple engineers working round the clock to develop digital representations of physical models. And just like the personal computer, technological advancement led to the creation of cloud-based digital twin solutions which made it possible for everyone to explore digital transformation and it is benefits.

Today, the digital twin market is expected to grow exponentially and this growth is being driven by the approximately 20 billion sensors and endpoints around the world. Advancements in IoT and IIoT have also played a role in increasing the adoption rate of digital twin technology which are some of the reasons why digital representations of almost any entity or process can be created today.

The benefits of the digital twin include the ability to make real-time decisions, receive insight from complex processes or systems, and plan better for the future. You can explore how digital twin can help your enterprise or individual pursuits by reading relevant case studies here. Now, to reap these benefits, a digital twin of a chosen process, object, facility, or system must be created which is what this post is all about. Thus, if you have ever wondered what it takes to develop a digital twin then bookmarking this is recommended.

5 Things You Should Know About Creating a Digital Twin

The task of creating a digital twin may sound daunting but like most activities diving in headfirst without overthinking simplifies the process. Once you have the required tools needed to create a digital twin, the supporting technologies such as Simio provides you with prompts and interactive information needed to complete the process. To successfully create a digital twin, here is what you need to know and the resources you need to have:

  1. Defining the System – The first step to creating a digital twin is defining the system, process or object to be digitized. To do this, an understanding of the entity is required and this can only be achieved through data capture. Thus, data defines the system to be digitized and introduced into the digital space.

The data capture process is generally fluid in nature and depends on the entity or system being considered. For manufacturing facilities, the data that defines a system or process can be gotten from assets within a facility these assets include original equipment, shop floor layouts, workstations, and IoT devices. Data from these assets are captured using smart edge devices, RFIDs, human-machine interfaces and other technologies that drive data collection.

With physical objects such as vehicles, data capture is done through sensors, actuators, controllers, and other smart edge devices within the system. 3D scanners can also be used to extract point clouds when digitizing small to medium-sized objects. The successful capture of the data a system or object produces defines the system and is the first step to creating a digital twin.

  • The Identity of Things – One of the benefits of a digital twin is the ability to automate processes and develop simulations that analyze how a system will operate under diverse constraints. This means the system or facility to be digitized must have its own unique identity which ensures its actions are autonomous when it is introduced into a system.

To achieve this, many digital twin platforms make use of decentralized identifiers which verify the digital identity of a self-sovereign object or facility. For example, when developing a digital twin of a facility, the entire system will have its own unique identity and assets within the facility are verified with unique identities to ensure their actions are autonomous when executing simulations within the digital twin environment.

  • An Intuitive Digital Twin Interface – Another important element or choice to make when creating a digital twin is selecting a technology or software that can help you achieve your goals. You must be clear about how the technology can help you achieve your goals of a digital twin. Some things you need to consider when choosing a digital twin software or platform include:
  • How the software handles the flow of data from the IoT devices or facility and other enterprise systems needed to understand and digitize the chosen process.
  • You need to understand how the software recreates physical objects or assets into its digital ecosystem. Some technologies support the use of 3D models and animations when recreating entities while others do not deliver that level of clarity.
  • When digitizing complex systems with hundreds of variables that produce large data sets, the computing resources needed to create and manage a digital twin is increased. This makes computing power and resources a key consideration when choosing a digital twin platform or solution. The best options are scalable digital twin technologies that leverage the cloud to deliver its services.
  • An intuitive digital twin solution also simplifies the process of creating digital representations of physical assets. The technology should also be able to understand the data produced across the life-cycle of an asset or at least integrate the tools that can manage the identity of assets within the digital twin.
  • Another key consideration is the functions you expect the digital twin to perform. If it is to serve as a monitoring tool for facilities or for predictive maintenance, a limited digital twin software can be used while for simulations and scheduling a more advanced technology will be required.
  • Start Small with Implementation – When taking on the implementation of digital twin technology, it is recommended you start small. This means monitoring the performance of simple components or a single IoT device within a system and expand with time. This hands-on approach is the best way to understand how the digital twin functions and how it can be used to manage larger systems according to your requirements.

With this knowledge, you can then choose to explore the more sophisticated aspects or functions the digital twin offers such as running complex discrete event simulations and scheduling tasks. A step by step approach to implementing or creating a digital twin provides more learning opportunities than initiating a rip and replace approach when developing one.

  • Understand the Security ConsiderationsAccording to Gartner, there will be 50 billion connected devices and 215 trillion stable IoT connections in 2020. As stated earlier the increased adoption rate of digital twin technology and the connected systems around the world bring up security challenges. These security considerations also affect the digital twin due to the constant transfer of data from the physical asset or process to the digital twin ecosystems.

When creating a digital twin, a plan must be in place to handle secure communication channels across networks and other vulnerabilities. To effectively do this, an understanding of the different communication protocols used within a system is required. This is why when choosing a digital twin technology, security challenges and how the platform mitigates risk must also be considered.

Top Trends in Simulation and Digital Twins Technology for 2020

Digital Twins refers to the digital representations of people, processes, and things. It is used to analyze operations and receive insight into complex processes. As 2019 comes to an end, the need to define digital twin technology still exists and hopefully by this time next year, its growth and popularity will make this need obsolete…

In 2018, digital twins were included as a top technology trend by the big names covering the tech industry. According to Orbis research, the digital twin market is expected to grow by 35% within a 5-year time frame and 2020 is right in the middle of this period. But before highlighting the trends to expect in 2020, it is only right to do a recap of the year so far. This is to note if earlier predictions have come to pass before mapping the future.

In terms of popularity, coverage of the digital twins is definitely on the right track as continuous studies by Gartner and other publications show. Today, many professionals across the technical and non-technical divide understand the digital twin concept and how it can be used to drive business processes and concepts. This is why many industries are currently integrating digital twins to bolster business insight and understand data.

The biggest adopters of digital twin technology in the geographical sense remains North America. Enterprises within the US and Canada currently leads the way in terms of adopting digital twin technology. North America accounts for approximately 59% of the digital twin market and economy while Europe and the Asian pacific comes next.

The very nature of the digital twin and simulation, as well as, the solutions they provide makes them attractive business tools for the manufacturing industry and this fact is backed up by data. The manufacturing industry’s affinity to digital twins is powered by Industry 4.0 and the varied ongoing processes that occur within shop floors. The use of smart edge devices, equipment, robots, AI, and automation also fits nicely into the digital twin concept thus making it attractive to manufacturers.

In 2019, manufacturers account for approximately 36% of the digital twin market. Other industries such as the energy and power industry, Aerospace, Automobile and Oil & Gas complete the top five industries who make use of the digital twin to enhance operations. Analyzing this trend highlights the fact that digital twins are important to simplifying complex processes where hundreds or thousands of variables and relationships are needed to successfully accomplish set tasks.

Is the Digital Twin for Only Production-based Industries?

Although the Oil & Gas industry, as well as, the energy and power sector are not tagged as manufacturing industries, a case can be made for it. Therefore, many may assume or wonder if digital twin technology is only useful within production-based industries where discrete or process manufacturing takes place. And the answer is No.

The digital twin is also being used in other industry verticals such as the hospitality industry and in restaurants. One example is the use of Simio by CKE Holdings Inc. to ease workloads in its Carl’s Jr and Hardee’s restaurants. The Digital twin is also being used to support discrete event simulations in hotels, real-estate, and tolling facilities.

The use of interconnected devices and automation within service and hospitality businesses are the driving forces behind the adoption of digital twin within a variety of industries. And the coming year is expected to witness continuous growth as more industries and professionals understand what the digital twin brings to the table.

Top 5 Trends for the Digital Twins and Simulation Technology for 2020

Interrelated Technologies will Boost Adoption Rate – The growth and maturity of interrelated technologies such as 3D printing, metal printing, and mapping will play a part in accelerating the adoption rate of digital twins in 2020. This is because of the need to monitor and consistently improve these technologies and the systems that drive them.

Using 3D printing as an example, many manufacturing outfits are currently making use of 3D printing clusters to speed up their production requirements. 3D printing clusters or farms refers to facilities where hundreds of 3D printers function simultaneously to manufacture physical items. Although these 3D printing clusters have dedicated software for managing the printing process, material delivery, scheduling, and managing the entire supply chain within these facilities are handled manually.

Digital twin solutions can eliminate the manual management and handling process in 3D printing farms to great effect. If properly executed, a digital twin of a large scale 3D printing cluster will provide a data-driven approach to optimize supply, scheduling and the manufacturing process. This will reduce expenditure including the energy expended in 3D printing cluster facilities.

Industry 4.0 will Continue to Drive Adoption – The growth in Industry 4.0 and the devices, as well as, communication channels driving the smart factory is expected to increase the adoption of digital twin solutions. In 2019, Industry 4.0 witnessed the creation of new standards from the OPC Foundation that supports the collection of data from the deepest corners of brownfield facilities. These data were collected from dumb equipment with legacy technologies using smart edge and embedded devices.

The success of this approach, means that digital twin technology can now integrate the data collected from dumb or legacy equipment when developing digital representations. This increases the accuracy levels of the representations thereby enhancing simulation results and scheduling plans. Thus, increasingly accurate digital twin ecosystems and results will create more use cases that will drive the adoption of digital twins in 2020.

IoT and IIoT to Drive Digital Twin Adoption Rate – The move to more interconnected environments across both manufacturing and service-based industries also have roles to play in 2020. As stated earlier, Industry 4.0 will enhance the adoption of digital twin technologies and this also true for the industrial internet of things (IIoT). The widespread adoption of IoT and IIoT devices or equipment have created a race to develop the best management solution to monitor interconnected activities.

This creates an avenue which digital twin service providers are currently taking advantage of and will continue to do so in 2020. The ability of the digital twin to create digital representations of IIoT devices and also integrate the data they produce creates multiple use cases enterprises will explore in the coming years. These use cases include running simulations in complex interconnected facilities to produce accurate results or to access processes that involve the use of IIoT technologies.

Digital Twin for Cybersecurity Challenges – With every passing decade, the cybersecurity challenges enterprises face keeps changing. The millennium brought Trojan horses and other viruses which were effectively stopped with anti-virus software apps and by 2010, attackers pivoted to using phishing attacks and malware. Today, ransomware, spyware, DDoS, and business email compromise attacks have become the new challenges enterprises face. Thus highlighting the ever-changing landscape of cyber threats.

To cater to these threats and attacks, digital twin solutions will be enlisted by enterprises in 2020. In this scenario, the digital twin will be used as a penetration testing tool to simulate the effects of successful data breaches or ransomware to an organizations business processes. Within the digital twin environment, attacks to core equipment can be simulated and the result will be a response pattern that ensures the crippled equipment does not lead to extended downtime.

2020 will also be expected to witness an increase in the cybersecurity threats facing cloud-based digital twin solutions. Thus, more secure communication protocols and standards regulating data use will be developed to protect enterprises making use of digital twin technology. This means developers and service providers will have an increased role to play in securing digital twin environments.

Simulation-based Scheduling – The drive to deliver real-time scheduling is expected to continue in 2020 as enterprises seek more accuracy with managing business process. The need for real-time scheduling is also driven by how enterprises intend to apply simulation and digital twin tools. An example includes the need to make business decisions in real-time, handle unforeseen occurrences such as machine downtime, and reschedule operations.

These challenges fall into the category of issues discrete event simulation (DES) software can handle. Once the required data is accessible, DES and digital twin applications can conduct simulations in real-time and provide accurate solutions to dealing with changing scenarios also in real-time. This will drastically reduce downtime and enhance performance within facilities and warehouses.

Although some DES software offers real-time simulation scheduling, many are still process-based scheduling applications and this is set to change in 2020.

Quantum Computing – If real-time simulation, scheduling, and process management is to be achieved, then digital twin solutions must take advantage of the speed, scalability, and high-performance quantum computing offers. Today, digital twin solutions currently leverage the cloud to provide stable and scalable services to enterprises and only a few integrate the use of high-performing computers to enhance or manage really large workloads.

In 2020, further strides will be made to speed up simulations within digital twin environments using high-performing computers. The success of this initiative will speed up real-time scheduling and complex process management for the foreseeable future.

Planning for 2020…

The benefits of the digital twin have played an important role in ensuring its adoption across diverse industries and the expected trends of 2020 will continue the increased adoption rate that came with 2019. Although digital twin solutions have become more interactive and intuitive to use, enterprises still require the assistance of experienced professionals to get the best out of their digital twin environment and this is where Simio can help.

IT managers, cybersecurity experts, and project managers can take advantage of the Simio Fundamentals Course to learn more about simulation and Digital Twin technology including its application in real-life scenarios.

Evolution of Discrete Event Simulation Software

Today, discrete event simulation (DES) software and the benefits it provides are currently being used across a majority of industries to simplify business operations, make predictions, and gain insight into complex processes. But before modern simulation software such as Simio could be used to create shiny models and execute real-time simulations, there were earlier technologies that formed the foundation built upon by modern simulation software. As you can probably tell, there is definitely a story behind the evolution of simulation software and today, that story is being told.

To accurately tell this story, the evolution must be arranged in chronological order. The traditional order currently in use today is the order outlined by R.E. Nance in 1995. This chronological order will be used here but with slight edits to accommodate the earliest memories of simulation software and the current strides being made. This is because the most referenced order outlined in 1995, did not take into account the efforts of Jon von Neumann and Stanislaw Ulam who made use of simulation to analyze the behavior of neutrons in 1946.

RE. Nance’s chronology which was written in 1995 could not and did not account for the recent paradigm shifts in DES software. This understandable omission will also be highlighted and included in this post. Therefore, this paper on discrete event simulation should be seen as an update of the history and evolution of DES software.

The Early Years (1930 – 1950)

Before discrete simulation came to prominence, early mathematicians made use of deterministic statistical sampling to estimate uncertainties and model complex processes. This process was time-consuming and error-prone which led to the early DES techniques known as Monte Carlo simulations. The earliest simulation was the Buffon needle technique which was used by Georges-Louis Leclerc, Compte de Buffon to estimate the value of Pi by dropping needles on a floor made of parallel equidistant strips. Although this method was successful, simulation software as we know it got its origin in 1946.

Sometime in the fall of 46’, two mathematicians were faced with the problem of understanding the behavioral pattern of neutrons. To understand how neutrons behaved, Jon von Neumann and Stanislaw Ulam, developed the Roulette wheel technique to handle discrete event simulations. The light bulb moment came to Ulam while playing a game of Solitaire. Ulam successfully simulated the number of times he could win at Solitaire by studying hundreds of successful plays.

After successfully estimating a few games, he realized it would take years to manually observe and pick successful games for every hand. This realization led to Ulam enlisting Jon von Neumann to build a program to simulate multiple hands of solitaire on the Electronic Numerical Integrator and Computer (ENIAC). And the first simulation software was written.

The Period of Search (1955 – 1960)

The success of both mathematicians in simulating neutron behavioral patterns placed the spot light on simulation and encouraged government agencies to explore its uses in the military. As with all technological processes, the growth of discrete simulation software could only match the computing units available at that time. At that time, analog and barely digital computers were the springing board for development.

Around 1952, John McLeod and a couple of his buddies in the Naval Air Missile Test Center undertook the responsibility of defining simulation concepts and the development of algorithms and routines to facilitate the design of standardized simulation software. In the background, John Backus and his team were also developing a high-level language for computers. The efforts of the multiple teams working independently of one another led to the development of the first simulation language and software that would lead to the evolution of DES software.

It also highlights the general theme of how technological advancements and software evolutions occur which is through advancements in diverse interrelated fields.

The Advent (1960 – 1965)

By 1961, John Backus and his team at IBM had successfully developed FORTRAN, the first high-level programming language for everyday use. The success of FORTRAN led to the creation of a general-purpose simulation language based on FORTRAN. This language was SIMSCRIPT which was successfully implemented in 1962 by Harry Markowitz.

Other general-purpose simulation software and systems also sprang up within this period as competing contractors continued to develop simulation languages and systems. At the tail end of 1965, programs and packages such as ALGOL, General Purpose Simulation System (GPSS), and General Activity Simulation Program (GASP) had been developed. IBM computers and the BUNCH crew consisting of Burroughs, UNIVAC, NCR, Control Data Corporation, and Honeywell were developing more powerful computers to handle complex simulations.

One of the highlights of this period was the successful design of the Gordon Simulator by IBM. The Gordon Simulator was used by the Federal Aviation Administration to distribute weather information to stakeholders in the aviation industry. Thus highlighting the first time simulation was used in the aviation industry.

Here again, the increase in processing speed and the prominent entry of a new term known as computer-aided design was to play a role in advancing the development of simulation software for use. At this stage, early simulation packages and languages were still being used predominantly by the government, as well as, a few corporations. Also, ease of use, intuitive, and responsive packages were slowly being integrated into simulation software such as the GPSS which had become popular in the 60s’.

The Formative Years (1966 – 1970)

The formative years were defined by the development of simulation software for commercial use. By this time, businesses had begun to understand simulation and the role it plays in simplifying business process and solving complex problems. The success of systems such as the Gordon Simulator also got industry actors interested in the diverse ways DES software could be employed.

Recognizing the need to apply simulation in industrial processes, the first organization solely dedicated to simulation was formed in 1967 and the first conference was held in New York at the Hotel Roosevelt. In the second conference, 78 papers on discrete event simulation and developing DES software were submitted. Surprisingly some of the questions asked in the 1968 conference still remain relevant to this day. These questions include:

  • The difficulties in convincing top management about simulation software
  • How simulation can be applied in manufacturing, transportation, human behavior, urban systems etc.

The Expansion Period (1971 – 1978)

 The expansion period was dedicated to the simplification of modeling process when using simulation software and introducing its use in classrooms. At this stage, diverse industries had begun to understand the use and benefits of simulation software to their respective industries. This, in turn, led to discussing the need to prepare students for a world that integrates simulation.

Also, advancement in technology such as the introduction and wide spread use of the personal computer made the case for developing simulation software for dedicated operating systems. This led to the development of the GPSS/H for IBM mainframes and personal computers. The GPSS/H also introduced interactive debugging to the simulation process and made the process approximately 20 times faster than previous simulation packages. In terms of technological evolution, the GASP IV also introduced the use of time events during simulations which highlights the growth in simulation software available to industries at that time.

By the fifth simulation conference tagged the ‘Winter Simulation Conference’ of 1971, diverse tutorials on using simulation packages such as the GASP2 and SIMSCRIPT had become available to the public. The growing popularity of simulation also led to increased commercial opportunities and by 1978, simulation software could be purchased for less than $50,000.

The Consolidation and Regeneration (1979 – 1986)

The consolidation age was defined by the rise of the desktop and personal computer which led to the widespread development of simulation software for the personal computer. Simulation software also witnessed upgrades through the development of simulation language for alternative modeling (SLAM). The SLAM concept made it possible to combine diverse modeling capabilities and obtain multiple modeling perspectives when handling complex processes.

These upgrades or development made simulation for production planning possible and the manufacturing industry began to take a keen interest in simulation software. The increase in computing and storage capacity also led to the creation of factory management systems such as the CAM – I. CAM – I effectively became the first simulation software used solely for closed-loop control of activities and process within shop floors.

By 1983, SLAM II had been developed and this was an industrial-grade simulation package ahead of its time. SLAM II provided three different modelling approaches which could also be combined at need. These approaches included discrete event modeling approach, network modeling, and the ability to integrate discrete modeling and network modeling in a particular simulation model. More importantly, SLAM II cost approximately $900 which was relatively cheap at that time. This can be signified as the moment where discrete event simulation came into its own as commercial software options for discrete event simulation modeling became available to the general public

The Growth and Animation Phase (1987 – 2000)

The 90s’ witnessed a consolidation of the strides made in the earlier years and many interrelated technologies and processes also came off age within this decade. This era focused on simplicity, the development of interactive user-interfaces, and making simulation available for everyone including non-technical individuals.

In the mid-nineties, simulation software was being used to solve even more complex issues such as simulating every event and process in large-scale facilities. The Universal Data System example was a first in those days. Universal Data System was stuck with converting its entire plant to a hybrid flow-shop which enhanced production. To achieve this, the company made use of GPSS and the end result was a successful flow that enhanced daily operations and the entire process was modeled and simulated within 30 days.

In 1998, vendors began to add data collection features to simulation software. These features included the automation of data collection processes, the use of 3D graphics and animation to make the simulation process more user-friendly and non-technical. Needless to say, the technological advancements in animation, modeling, graphics design, and UI building played roles in enhancing simulation software during this period.

The Flexibility and Scalability Phase (2000 – 2019…)

Finally, we come to the last evolutionary phase of the DES software as we know it. Once again, advancement in interrelated technologies have made scaling simulation and speeding up its process possible. The evolution that came with the new millennium saw DES vendors leverage the use of cloud computing, AI, and high-performance computing to take simulation to greater heights.

Other changes that came within these decades was the evolution of production-based scheduling process to a simulation-based scheduling process. This shift allowed for real-time simulation scheduling, processing, and decision-making. This shift also comes with the fourth industrial revolutions were data collection, automation, and interconnectivity rule. Simulation software of this generation has evolved to become tools capable of digitization and the development of digital twins.

Discrete event simulation software such as Simio are examples of the comprehensive simulation technologies that are needed to drive Industry 4.0. This is because new age DES software must be able to collect and store its own data, model accurate 3-D graphics, animation, manage real-time scheduling, and digitization. They must also be equipped with features that market it possible to leverage cloud computing, integrate enterprise resource planning applications, and high-performance computing. These features all work together to ensure the most complex simulations are executed to deliver accurate answers or insights when applied in professional settings.

Summary

The future of discrete event simulation is by no means set in stone as the experiences from previous eras have shown. This means with the advancement in interrelated technologies and simulation software, more industrial concepts and business models will be disrupted in the coming decade. 

Simio Showcases the Digital Twin at INFORMS Annual Meeting 2019 – A Recap

The INFORMS Annual Meeting for 2019 has come and gone with multiple keynotes shared, workshop activities, and hundreds of excellent companies sharing their experiences and solutions from brightly colored booths. Once again, Simio was at the thick of things evangelizing the benefits of simulation and Digital Twin technology to the world. As with all annual meetings, the focus was on the strides been made in operational research and analytics. And the meeting provided the chance to explore emerging technologies and its applications across all ‘works of life’.

The term ‘all works of life’ wasn’t used lightly as sessions covering social media analytics and e-learning to applying analytics to human trafficking were explored. As for Simio, our role was somewhere in the middle and as stated earlier, our participation was centered around the digital twin. But before going into details of how the event panned out and Simio’s roles, here is an outline of what the INFORMS Annual Meeting is about for interested individuals.

INFORMS Annual Meeting

INFORMS which stands for the Institute for Operations Research and the Management Sciences is an umbrella organization for professionals plying their trade in operations research and analytics. INFORMS currently boasts of approximately 12,500 members across the globe which highlights its global or international reach.

The organization also sets standards and guidelines to ensure research and analytics within its field are ethically done. To bring its thousands of members together under one roof, the INFORMS Annual Meeting event was created and it holds once a year. The event features keynote sessions, workshops, publication presentations, and an exhibition area for member and enterprises to showcase their wares.

The INFORMS Annual Meeting also coincides with its community service drive to assist non-profit organizations with meeting their obligations. This is done through the INFORMS Pro Bono Analytics section of the organization. If you are wondering why the information about Pro Bono Analytics is included here, then I ask for patience as it will all make sense in the end.

Now to the annual meeting of 2019!

The 2019 INFORMS Annual Meeting was a 3-day event which ran from the 20th of October to the 23rd. This year’s event was definitely a success as more than 5,000 people breezed through the different sessions, exhibition areas, workshops, and lunch areas throughout the 3-day event. The convention center buzzed with activities through these days and we are proud to say Simio capitalized on these activities in different ways. Our participation included a dedicated Simio booth highlighting the use of Simio digital twin technology, a session handled by Jason, and workshop presentations from Renee.

Keynote Sessions and Workshops of Note at the INFORMS Annual Meeting

Tens of session covering operations research and analytics were covered throughout the event which makes mentioning and discussing every one of them impossible. So, the focus will be on simulation, digital transformation, cloud computing, and digital twin sessions.

One of the exciting sessions within the above category was the session about the computational infrastructure for operations research, COIN-OR, initiative. The IBM project focuses on providing open-source technologies solely for computational operations research. The end goal is to provide an open-source library of tools which will ensure researches do not have to start from scratch when handling complex research. This creates a foundation that will be built on and maintained by researchers over the years.

The session ‘Robust Optimization and Learning Under Uncertainty’ was also interesting as it discussed the challenges stakeholders face with decision-making and policy creation. Han Yu, a PhD student at the University of California spoke about how important data collection, and an understanding of history should drive real-world decision-making. The session also discussed how modeling and robust optimization techniques can enhance the decision-making process.

Other notable sessions highlighted or raised questions about the role digital twin and simulation could play in enhancing agriculture and the healthcare industry. According to Greg from Syngenta, AI, computer vision, and bioINFORMSatics modelling currently assist Syngenta with making data-driven seed selections and breeding. This raises the question of the role of the digital twin in agriculture which may be explored in other blog posts.

In the ‘Healthcare Modeling and Optimization’ session, Dr. Zlatana Nenova spoke about the role modeling and data analytics play in improving healthcare. Her speech also touched on the use of digital technology to analyze medical care policies for both off and on-site healthcare delivery. In terms of on-site healthcare, there are certainly diverse ways the healthcare industry can benefit from digital twin technology. Although this was not covered in this year’s event, it highlights the possibilities of applying digital twin to the healthcare industry.

Simio’s Events at the INFORMS Annual Meeting

Now, to Simio and our role at the INFORMS conference. In last year’s event, Ms. Renee Thiesing, the VP of Strategic Alliances,  spoke excellently on the role Simio plays in driven discrete event simulation and the digital transformation of brownfield systems as the move to Industry 4.0 continues. She also highlighted the importance of real-time event scheduling and how Simio can help enterprises solve real-time scheduling challenges using Simio.

In this year’s event, Ms. Renee built on her earlier foundation by focusing on the digital twin capabilities of Simio and its application in diverse industries. Her session titled ‘New Innovations: Cloud Computing, Real-Time Scheduling, Industry 4.0 and more’ discussed how Simio leverages cloud computing to deliver high-performing scheduling and simulations.

Through the session, she discussed how Simio leverages the computing power of Microsoft Azure to support complex applications. Simio’s compatibility with Schneider Electric’s Wonderware was also discussed in detail. This includes the leveraging of Wonderware to achieve detailed production scheduling in real-time, as well as, manage real-time risk analysis. The new Simio features such as Simio’s cloud portal and OptQuest were also covered during her workshop. She highlighted OptQuest abilities to optimize scheduling and simulation with the aim of delivering optimal solutions to complex business problems.

Jason Ceresoli also spoke on the benefits of using Simio’s 3D modelling capabilities to solve real—world problems. His presentation covered Simio’s features for system design and operation. Practical examples of how Simio’s rapid 3D modeling, planning and scheduling, and optimization capabilities can be used by enterprises were also discussed by Jason. Finally, his session highlighted the difference between Simio and other simulation tools with a focus on how professional researchers and analysts can use these features. 

Our participation at the INFORMS Annual Meeting will not be complete without recounting our experiences at booth 28 in the exhibition area. The targeted message used in the Simio booth drew its own audience of professionals, entrepreneurs and business representatives interested in the digital twin. This gave us the opportunity to showcase Simio’s features and real-world applications to interested individuals. We can categorically say our booth played a role in the sales leads and opportunities we got from the event.

Simio and the Pro Bono Analytics Event

I remember introducing you to the INFORMS Pro Bono Analytics and now here we are! This year, Pro Bono Analytics partnered with a Seattle-based non-profit organization, FareStart, to assist individuals interested in building careers in food service and culinary arts. At this year’s INFORMS Annual Meeting, Simio alongside other participants made donations to the FareStart initiative.

The event was a success and according to Elise Tinseth, Community Engagement Manager with FareStart, shared, “The INFORMS Pro Bono micro-volunteer opportunity of creating hygiene kits is impactful to eliminating barriers our students who are experience poverty and homelessness have to getting jobs in the food service industry.’ She also thanked everyone who made out time and donated resources to help FareStart meet its goals.

INFORMS Annual Meeting Awards and the Future

And lastly, the INFORMS Annual Meeting Awards. Although Simio did not bag any of the awards, the pomp and pageantry, as well as, the strides made by researchers are worthy of a mention in this post. Hopefully, the prize for teaching operations research and management science may be ours. That being said, the 2019 event was a success and Simio will continue to be a part of the INFORMS Annual meeting for the foreseeable future.
