Hello, In my SIMIO model there is a decision point and in this point some entities will be accepted and some of them will be rejected. For accepted entities, there are 3 different routes through the 3 different servers. So, I would like to create a rule in this decision point as follows: From 6am to 10am, entities would be accepted with probability (1-p1) and transferred to server A. So, entities would be rejected with probability p1. From 10am to 6pm, entities would be accepted with probability (1-p2) and transferred to server B. So, entities would be rejected with probability p2. From 6pm to 10pm, entities would be accepted with probability (1-p3) and transferred to server C. So, entities would be rejected with probability p3. So, I do not know how to determine the time schedule for link weight for each rout. I really appreciate if anyone can help me,

I wanted to simulate a short transport form Source to Sink - to analyze waiting times resulting from queues (with 4 vehicles in Scenario1 and 5 vehicles in Scenario2). In Output@Source1 I set "Initial traveler capacity" to 1 - to ensure that only 1 vehicle can be loaded in a given moment and that the rest must wait (and animation of process looks alright). However in results pivot, almost 100% of vehicles time is transport time and almost none is idle time (even though vehicles spend significant amount of time waiting for their turn at Source). Could you tell me what did I do wrong and how to measure idle time correctly? Model.spfx

Greetings, Trying to set up 2 separate networks (AGV and Tractor networks). I can create the Network Element in Definitions, but I cannot figure out how to assign the paths and nodes to the new networks. I tried the SetNetwork process step, but I get a runtime error: "The object or element reference 'Path 5' returned by property 'SetNetwork.EntityObject' is not of the expected type 'Entity'." How do you set a path's new Network name? Link to the model, with the runtime error (error comes from the OnRunInitialized process): https://www.dropbox.com/s/ehn33oxxed5ir43/2-Netowrks.spfx?dl=0 thanks for any help, Kurt

Try the logic included in this model. Note that you can use the same logic at any time over the simulation run. In this specific example the entities are created at the begining of the simulation run. If you need to create them at any time over the simulation run then you should define a seperate process then embed the same logic into that process. Then, all you need is to trigger that seperate process. For example, you can trigger by using timer element. Hope it helps?. CreateEntities.spfx

Hi, usually the time related values must be in hours. In your case i guess it would be: Run.Timenow-ModelEntity.TimeCreated < 1.0 Try that. Rds.

I wanted to know how to compute a resource state time for a worker object with a dynamical population over experiments. I know how to do for a fixed population, and sum over all the population gives me the desired computation but I don’t want to put a lot of decides to do when the population is a dynamical property. Is it a more natural way in Simio instead of using the way: WorkerName[1].ResourceState.PercentTime(7)+WorkerName[2].ResourceState.PercentTime(7)+...? Thank's!

Hi, I have a bottleneck at the end of my assembly line. I cannot dupplicate that station as my total number of workers is already high. Before hiring, I would like to try and reallocate and have satellite employees. I want to allocate my workers to that station when the input buffer has exceeded one entity. Every worker has to finish the entity they are presently working on at the other stations and the first workers that are done need to go the bottleneck station. The rest of the time, the workers can be allocated based on the smallest distance to the work stations. The bottleneck station usually requests 4 workers. That information is already set up in a table. When there is two entities in queue in that buffer, I want workers to be able to go finish the work and hence increase the processing time by X. I have tried a lot of different things, and all my data is stored in relational tables. Thanks!

That is what I thought. However, my results are not making any sense. I see the following: Logically, adding 5 hours of travel time via an interdiction should lower the responses (at the very least the FuelTotal) however, this is not the case. Just as a quick test I changed the interdictions to negatives and received more logical results. However, when I view individual runs of each of these cases, the opposite of these results is what I receive: Fuel levels plummet and reach 0 multiple times during the scenario since the transports can't keep up (w/ 5hr interdiction) or the transports 'teleport' to the ACo node since there is a -5hr interdiction and therefore the transports are always able to keep the servers at high fuel levels. I must be missing something here.

Hi Amine, I have defined a new process named process1 which is triggered by Input@BUFFER_ST_1.Entered event. Then, I used interrupt step (in process 1) to get one entity from processing station whenever process 1 is triggered. Note that I set the processing time of BUFFER_ST_2 server to infinity to hold entitys until Input@BUFFER_ST_1.Entered event is occured. I am not sure if setting this to infinity is a problem?. Other than this everything is ok and it seems it works. Buffer varianti trazioni V2.spfx

First of all, Hi! This is my first time posting after some months of stalking in the shadows of the forum and after what I've seen, I'm certain I'll find my answer here! I've been working with Simio for some time now, and there has been something bothering me for a while, if something in a binded file changes, so does in Simio after you import the table again, or (if you have it on automatic) restart the simulation. But what if mid-run you wanted to add some values to one of your tables after a change in the file was made but you can't allow yourself to restart again? (A bit of a dramatic case, I know!) I've already seen that you can re-import data mid-run, but the values Simio uses don't get updated instantaneously while running, it's like it adds them to the table but waits for the next run to use them! So, my question is, is there a way to make Simio take in those new values in the binded table without the need to restart the simulation? Thanks to everyone in advance!

We continue to welcome volunteer involvement in our student competitions. 1) We welcome ideas for new competition problems. 2) We welcome your involvement in creating a problem. This could be scaled to any level ... from simply providing some detailed modeling situations and possibly blinded data up to public sponsorship and recognition of your organizations involvement. 3) If you would like to practice your skills by getting early access to a draft of the problem, we would welcome your involveent as long as you have no other competition involvement and commit to secrecy :). 4) We are always looking for judges. It typically requires a time commitment of about 6-8 hours spread out over about 7-10 days. Please contact me (dsturrock@simio.com or academic@simio.com) if you can help us with any of the above. Thanks in advance, Dave Sturrock

You are probably aware that Simio LLC sponsors a simulation competition twice each year. You may not be aware that this is already the largest simulation completion anywhere! In the latest contest, we had a total of 250 teams involving 868 students from 33 schools in 14 countries. Part of this is based on Simio's popularity, but part of it is because we have very interesting and realistic problems based on heavy practitioner involvement. It does require a lot of effort to conduct each competition, including: 1) Finding realistic problems (do you have a problem to solve?) 2) Fleshing out the problem statement 3) Developing test solutions to ensure each problem is balanced and solvable at the right level of difficulty. 4) Judging the entries We have had strong simulation community involvement, but we are always looking for more help with all 4 areas above. At the time of this writing we are looking for some help in the May 2017 competition in number 2 above. If anyone would like to help by testing the latest problem http://www.simio.com/academics/student-competition.php please contact me directly. I have previously been contacted by commercial users, early in their career, who have asked to participate in the contest or are just looking for a realistic problem on which to practice their skills. This is your opportunity. I'm sorry, but current students, or anyone affiliated with a school that expects to participate, are not eligible for this "early look" at the problem. All others, thanks in advance for your help.

One easy way is to build an output table and write there the timenow every time the vehicle fails o it's repaired. Here's an example. Hope this helps Rds. Mauricio Example Failing Vehicle.spfx

Hello Simio Forum. I’m just starting a model which, for me, is a little unique as I have only used servers in a task capacity through steps. The new liquid ink model consists of 4 lines with each line made up of 3 steps each having a volume of 3.5 tonnes. 1. PreMix 2. Mill with a recirc tank 3. PostBlend I do not seem to be able to model this using servers because I cannot represent the transfer time of product occupancy between steps. I need this to show utilisation/uptime of the steps. But when I look at using "Flow" tanks I cant add the process tasks the same as servers (rows) i.e. gather weigh, milling time, QC etc.. Plus will need to add/link worker steps. Is there a middle ground between servers & tanks? Thanks Martin

I want to show total change over time on a response in Experiment. But, I don't know how to type on Expression of response. I tried like this "Workstation1.ResourceState.TotalTime(ChangeoverLogic.TotalChangeoverTime)" , but it didn't work. How can I do?

I'm making a manufacturing model. I have four entities. I want to set 2 points on the below. 1. from transforter node to workstation, entities go to worksations which has the shortest queuing time including changeover time. If I can, I want to make constrains that the number of entities go to workstation. For example, 2 of A are proceed and 2 of B, 3 of A are proceed and 3 of B like this. 2. The entities are generated following ratio and also generated when the process of workstation is finished. Please let me know how can I do. Thank you.

I want to calculate the idle time of the worker in different time windows throughout the week. For example I want to get data regarding the idle time of my workers from 7 am to noon and noon to 5 pm in weekdays and 7 am to noon in weekends. Does anyone know how I can get this data and save all the idle times in different time windows?

Hi, I want to generate one type of product with one interarrival time. I have one source and one model entity. However, this entity can have different lengths following probabilities. Depending on these properties, the processing times at the servers will be shorter or longer. I tried to assign a state to the entity before this entity exits the source so ModelEntity.Length becomes DataLength.prob.randomrow. where DataLength is a table with the different lengths and the probabilities associated with those Lengths. The only thing is that it is a property and not a state, but I do not know how to do it in another way. Afterwards, I have different processing times at the servers depending on the different characteristics of my entity. For example, server1 will have different processing times depending on the length. How can I reference to the good processing time say I have added a column to the table DataLength with the associated processingtimes according to the lengths? Finally, I would also like keep track of those different lengths generated and see what the model produced in the end. Thank you for your help, Emilie

Hi, I want to record the ending time of my model in my experimentation. I want to know how much time did my model took to finish all the entity. Can you help me please

Maybe it's something trivial, but I want to know, a much time a transfernode is occupied by an entity, I've modeled a simple model, where the entities, wait in a transfer node until a station turns free.

Hello, I am just trying to improve my model. The worker is performing task on server 2 and can transport parts from server 1. Now, I want the worker to transport different parts based on their weight, so the travel time will be different. Example, when it is part A, so the travel time will be 5s or 10s for part B. Thanks for your help. Model12.spfx

Hi, I have different products to be processed on 2 servers and would like to batch 20 units on a pallet using Combiner. I have set a data table with different processing time for the products. Is the server is able to consider the 20 units on the pallet or just the pallet as 1 unit? Thanks.

I want to trigger an event based on the cumulated flow time (or the cumulated time when flowregulator.enabled = true) of a flow node. I tried to use the Timer and set the interval type of "TimeInState", but it doesn't work. Any ideas?

I have a model where a resource needs to be shared between 3 servers based on a time schedule. For example, at 1:00 AM, the resource needs to be at server 1. at 2:00 AM, the resource needs to be at server 2. at 3:00 AM, the resource needs to be at server 3. at 4:00 AM, the resource needs to be at server 2. What is the best way to implement this when you have a schedule for 24 hours?
