  4. Hello, We are evaluating Simio and really like what we see from exploring the Simio Personal Edition. Custom Dashboards are a high priority for us and we appreciate the fact that Simio seems to allow creation of custom dashboards from within a model; however, we would like to know if Simio allows the creation of custom dashboards that are portable from model to model. For example, we would like to: Create a dashboard that displays a chart depicting activity cost per entity (for a selectable set of entities) over the simulation period. Reuse/import this dashboard into any model to display the activity cost per entity over the simulation period (for a selectable set of entities). Two questions: Is this possible with Simio? If yes, which edition(s) of Simio support this capability? Thanks in advance! Donovan

  8. Hello! In reference to your question "How to use Simio as an external simulation routine (respectively, how to control Simio from other software e.g., R)?", did you figure out an answer that suited your needs? I saw that your question post in SI General Discussions received a post from lstretton. What was the follow-up on that? I am unsure of where to go to get further information on the steps for that. I'm new on the forum. My problem seems to run in line with yours. I have data that populates an excel csv file and I want to import that into Simio for my simulation. Eventually I would like to automate the runs of a bunch of difference replications, potentially with R or Python or something like that. Thanks, ftiller

  10. Hi Glen, I need your support for an error that I have to manage very often. My company set an automatic backup on One Drive and that is creating problem to load your Add-In. The body of the error is the following: Exception in loading types from 'C:\Users\username\OneDrive \documents\.\SimioUserExtensions\ExportImportModelAddIn.dll', message: 'Could not load file or assembly 'file:///C:\Users\username\OneDrive\documents\SimioUserExtensions\ExportImportModelAddIn.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)' Loading 'C:\Users\username\OneDrive\documents\.\SimioUserExtensions\ExportImportModelAddIn.dll' may have failed because the DLL was copied from another computer and has been blocked by Windows. To unblock it, copy the file to a user writable directory, right click on it and select Properties, on the General tab, click Unblock, then click OK, and then copy it back to your UserExtensions folder if necessary. Off course the file is unblocked, do you have some suggestion to fix it? Simio version is 11.197.19514.0

  11. Simio has a number of enabling features that are not widely known. When you save a project file, most people use the .spfx extension which is a compressed binary file. But if you would like to take advantage of a version control software (VCS), you generally want the VCS to manage versioning and file compares and file compression, itself. Simio has a multi-file project format referred to with a .simproj extension, which is designed with exactly that purpose in mind. Ths format involves a single key simproj file and a related set of folders that contains the uncompressed version of all the included components. This allows VCS to recognize when a small change to your model is made that it only needs to save that small change and not the entire model. While this works with any VCS, internally at Simio we use Tortoise SVN (http://tortoisesvn.net/) which works quite well for us. Simio also has some built-in features to help track and maintain model/library versions. If you right-click on an object (a model) and select "Properties" you will see a set of model properties for that object including Version. This version number is referenced when loading this object as part of a library to help evaluate if an object has been changed and if the change should be accepted (more on this below). Some additional model properties including Description, Keywords, and Categories. These are available in your model, plus they are available externally. For example the Sample SimBit Solutions interface uses these properties to help you quickly find a SimBit of interest. Some of them are also used in the Model Documentation Report. Speaking of which, the Model Documentation Report is designed to provide a quick way of examining all non-default parameters in your project. It can be useful to instructors evaluating assignments or as a way to record or share a snapshot of your model data. If you click on your Project name in the navigation window, the click on Models and the Edit ribbon you will see various options for subclassing, cloning, and copying library objects. These options, while subtle, give you greater control over how the lineage of an object wil be handled. You will also see options on this ribbon to protect your object from viewing and editing, and also to describe changes that have been made with the latest version.

  12. You can assign each entity an individual ModelEntity.Priority and set your Combiner to only match entities with the same priority. Check my attached model to see an example. Match Priority.spfx

  13. And also, not only do I want to select one randomly, but taking into account one column that would have the weight. For example, 80% of "Type A" that are "Good" goes to "Server_1" and 20% to Server_2. Basically use RandomRow to a table filtering for more than 1 foreign key

  14. Simio is a Simulation Modeling framework based on Intelligent Objects. This may be a bit different than other simulation packages that you may be familiar with, even those that market themselves as object oriented. Simio is designed from the ground up to support the object modeling paradigm; however it also supports the seamless use of multiple modeling paradigms including a process orientation and event orientation. It also fully supports both discrete and continuous systems, along with large scale applications based on agent-based modeling. These modeling paradigms can be freely mixed within a single model. The intelligent objects are built by modelers and then may be reused in multiple modeling projects. Objects can be stored in libraries and easily shared. A beginning modeler may prefer to use pre-built objects from libraries; however the system is designed to make it easy for even beginning modelers to build their own intelligent objects for use in building hierarchical models. An object might be a machine, robot, airplane, customer, doctor, tank, bus, ship, or any other thing that you might encounter in your system. A model is built by combining objects that represent the physical components of the system. A Simio model looks like the real system. The model logic and animation is built as a single step. An object may be animated to reflect the changing state of the object. Simio is a family of products that includes the Design, Team, Enterprise and Portal Editions. Models built with the first three Editions are fully compatible both up and down the product family and provide the same powerful 3D object-based modeling environment. Many simulation packages are built on outdated 2D technology that limits your ability to visualize your process or capture 3D spatial relationships in your system. Some of these older products limit you to 2D only models, while others offer expensive/complex 3D add-ons that require you to build a separate 3D visualization of your system, and then tie these two separate components together. These extra steps add unnecessary work and time to your project, and make your model and animation difficult to edit and maintain. In contrast, Simio provides a true object-based 3D modeling environment which lets you construct your 3D model in a single step from a top-down 2D view, and then instantly switch to a 3D view of your system. You simply drag and place your 3D objects from an Object Library into your facility view of the model. All Simio model-building products directly integrate with Google Warehouse to allow you to quickly download from a massive library of freely available 3D symbols to easily and quickly add realism to your models.

  15. Simio was the hit of the show at the recent Winter Simulation Conference. This topic will eventually contain a reproduction the entire talk given at WSC by Dennis Pegden. You can find many more introductory and training videos and webinars on the Simio web site (about 15 hours total) as well as still more on YouTube (many posted by users).

  16. First of all, I won’t argue with you at all – I would also like to see Simio have more intuitive behavior in our Standard Library objects. But perhaps my explanation below will make it a little bit more intuitive. But the good news is that, unlike other products that limit the behavior to one of a few predefined choices: 1) In Simio your choices are unlimited - it is not too difficult to make it behave exactly as you want. The OnCapacityChanged add-on process (or related processes like On Shift and Off Shift) can use the Interrupt, Suspend, and Resume Steps as illustrated in several SimBits. 2) If you want some behavior to be your default behavior, just create a custom object with that behavior. If you think about the built-in behavior as follows it might help… PARADIGM: A resource of capacity > 1 still represents a single resource, but just has the ability to process multiple concurrent entities. But it still only has a single state (Idle, Busy, Failed, …), e.g. if it is failed, the entire resource is failed (all capacity units), and if it is off-shift (e.g. capacity=0) all units are off-shift. REDUCING CAPACITY: When capacity available is reduced below the current number of busy units, there are many possible valid behaviors depending on your system. The default behavior of our standard library is simply to finish working on the current entity, and then take the unit off-line. But you can use the tools mentioned above to change that default. For example, you might implement some behavior that says “if I am within 10 minutes of completion, go ahead and complete it, otherwise record its remaining time, add 5 minutes of restart time, then put it at the beginning of the waiting entities”. OFF-SHIFT: When a resource is taken off-shift (capacity=0) all units are off-shift. Current Standard Library behavior causes all processes to be suspended (Suspend/Resume Steps) while it is off-shift. This essentially means that everything is “frozen” in place. The entities are not removed from the resource, but rather just suspended so no progress is made during the off-shift period. When the off-shift period is complete (e.g. capacity > 0) then all the entities resume exactly where they left off. Unfortunately that last phrase is what causes the unexpected behavior when you suspend at one capacity and then resume at another lower capacity. You are essentially combining the two above paragraphs. You suspend all activity while off-shift, then after you resume, you will behave as though you had just reduced the units in service, which under the default behavior says keep working on the entities in process until they are completed. In your case, it sounds like you would want to add content to the On Shift process so that if capacity is set to less than the number busy, that you would want to Interrupt the remaining entities and send them back to the entry queue. And then perhaps build that behavior into a custom Server object and use that object routinely.

  17. I can catch you on skype to show you for I have various timers performing different things.... One example would be where I have priority based maintenance...i.e...Shutdown...Planned...Breakdown....each running off of their respective timers...As these activities timers can overlap as they form part of their own unique distributions, events are fired based on the priority constraint to allocate the transporter a different state...The logic involves correctly disposing of the tokens in a wait state of the previous constraint process as well as resetting and adjusting the timers....i.e....If I am on breakdown and scheduled maintenance hits, then the schedule maintenance process is executed and Breakdown processes stopped or delayed until a corresponding event is fired....this includes material handling assignments, crew, etc.... Another example would be dynamic generation of "demand" transporters based on a varying monthly rate dictated by variations in supply due to statistical randomly generated constraints... The timer is adjusted based on a change in arrival rate which is calculated and dynamically updated to ensure that there is always just enough demand for current available supply...This forms part of optimized planning for bulk carriers which cost a hell of a lot of money if they are just chilling in the ocean... But ultimately and perhaps the crown jewel is handling flow transfers from one transporter to another...since i had developed the logic before this super awesome new release of the transporter library, I needed events to check when the load or discharge level had been reached, or the full or empty state of the flowcontainer had been reached on either transporter, or objects fired events which needed to seize loading/discharging and stay, or seize loading/discharging and move away, as well as handle inherent timers on the transporter for breakdowns that will execute different processes depending on the type of breakdown....i.e. move the transporter or stay put... It all sounds really complex but its very simple.... Hit me up on skype...

  19. The standard library vehicle has the option of a loading and unloading time per entity, but it is often difficult to model a situation where a vehicle stops for a specified time (like a bus or train). This object (with an example model) adds a single reference property and a single step to the standard Vehicle to allow you to specify that time. Smple, but convenient.

  22. A common way to create object definitions in Simio is by combining other objects, for example combining machines and a robot to define a work cell object. This type of object is called a composed object because we create this object by combining two or more component objects. This object building approach is fully hierarchical, i.e. a composed object can be used as a component object in building higher level objects. A second, more basic method for creating objects in Simio is by defining the logical processes that alter their state in response to events. For example, a machine object might be built by defining the processes that alter the machine state as events occur such as part arrival, tool breakdown, etc. This type of modeling is similar to the process modeling done in traditional modeling systems in use today such as Arena or GPSS. An object that is defined by describing its native processes is called a base object. A base object can in turn be used as a component object for building higher level objects. The final method for building objects in Simio is based on the concept of inheritance. In this case we create an object from an existing object by overriding (i.e. replacing) one or more processes within the object, or adding additional processes to extend its behavior. In other words we start with an object that is almost what we want, and then we modify and extend it as necessary to make it serve our own purpose. For example we might build a specialized drill object from a generalized machine object by adding additional processes to handle the failure and replacement of the drill bit. An object that is built in this way is referred to as a derived object because it is sub-classed from an existing object. Regardless which method is used to create an object, once created it is used in exactly the same way. An object can be instantiated any number of times into a model. You simply select the object of interest and place it (instantiate it) into your model.

  23. The Simio object framework is built on the same basic principles as object oriented programming languages; however these principles are applied within a modeling framework and not a programming framework. For example the Microsoft development team that designed C# applied these basic principles in the design of that programming language. Although these same principles drive the design of Simio, the result is not a programming language, but rather a modeling system. This distinction is important in understanding the design of Simio. Simio is not simply a simulation modeling tool that is programmed in an OOP language (although it is programmed in C#). Likewise it is not simply a set of classes available in an OOP language such as Java or C++ that are useful for building simulation models. Simio is a graphical modeling framework to support the construction of simulation models that is designed around the basic object oriented principles. For example when you create an object such as a “machine” in Simio, the principle of inheritance allows you to create a new class of machines that inherits the base behavior of a “machine”, but this behavior can be modified (overridden) and extended. Whereas in a programming language we extend or override behavior by writing methods in a programming language, in Simio we extend or override behavior by adding and overriding graphically defined process models. This distinction between object oriented modeling and object oriented programming is crucial. With Simio the skills required to define and add new objects to the system are modeling skills, not programming skills.

  24. Simio is a simulation modeling framework based on intelligent objects. The intelligent objects are built by modelers and then may be reused in multiple modeling projects. Objects can be stored in libraries and easily shared. A beginning modeler may prefer to use pre-built objects from libraries; however the system is designed to make it easy for even beginning modelers to build their own intelligent objects for use in building hierarchical models. An object might be a machine, robot, airplane, customer, doctor, tank, bus, ship, or any other thing that you might encounter in your system. A model is built by combining objects that represent the physical components of the system. A Simio model looks like the real system. The model logic and animation is built as a single step. An object may be animated to reflect the changing state of the object. For example a forklift truck raises and lowers its lift, a robot opens and closes its gripper, and a battle tank turns its turret. The animated model provides a moving picture of the system in operation. Objects are built using the concepts of object orientation. However unlike other object oriented simulation systems, the process of building an object is very simple and completely graphical. There is no need to write programming code to create new objects. The activity of building an object in Simio is identical to the activity of building a model – in fact there is no difference between an object and a model. This concept is referred to as the equivalence principle and is central to the design of Simio. Whenever you build a model it is by definition an object that can be instantiated into another model. For example, if you combine two machines and a robot into a model of a work cell, the work cell model is itself an object that can then be instantiated any number of times into other models. The work cell is an object just like the machines and robot are objects. In Simio there is no way to separate the idea of building a model from the concept of building an object. Every model that is built in Simio is automatically a building block that can be used in building higher level models.
