  1. I would like to refer to the BicycleAssembly Simio Simbit as I'm using it as a reference to set up my own model. As I set the Initialization step of my model, I read the Orders table row by row, using a global variable called CurrentRowNumber. However, when an order entity is created, I would like to keep track of the row in the Orders table that entity is created from with a model-entity level state variable. However, I'm not sure how to do. I cannot just assign the value of this ModelEntity.State = GlobalCurrentRowNumber as the GlobalCurrentRowNumber continuously changes as the simulation runs. May I have some suggestion as to how to do so? Thank you
  2. In the source of my model, I would like to generate arrival events by looking through row by row of a given table. However, I only want to create the 2nd arrival event when all the entities of the created by the first arrival event has moved beyond a certain point, where Globalstatevalue = 0. So in my process flow, I did something like this:When the globalstatevalue = 0, I want to go to the next row of my table and generate the 2nd arrival. I did this my fire an event The setting at my source: Arrival Mode: On event Triggering Event Name: name of event that I fired in the process flow. I managed to get the initial arrival to make sure that the Globalstatevalue = 0. condition is reached. However, the 2nd event is not triggerd at all and the CurrentRowNumber is not incremented as well. May I have some advice please? Thank you
  3. Hi, I would like to ask on the Bicycle Assembly SIMIO example. In the example, under the Manufacturing Orders table, they have created an integer state variable called RowNumber, which I thought could have been created under "States" in the "Definitions" tab. However, when I went there to find the state variable RowNumber, I could not find it inside there. Hence, may I know how the state variable was created? Thank you!
  4. Hi, How can I change a state variable of a flow entity? For example, I want to change the color (i.e. picture state) of the entity based on the flow connector that the entity enters. Any suggestions how to do that (apart from converting the flow entity into a discrete entity and then back to a flow entity)? Especially, because flow connectors do not have Add-On processes. Any ideas are appreciated. I have already reviewed the SimBits for flow library and could not figure out. Thanks!
  5. Dear All, New to Simio and struggling with the following problem. I would like to model an entity to exit a server at its assigned time as a state variable for now, I know this: Every entity is assigned before exiting the source with a state variable (pick-up time): TimeNow + random value between 1 -5 I want to use this state variable to decide with an add-on process if the server can finish processing; TimeNow == pick-up time if not, the server keeps processing. In other words, the processing time of the server depends on the state variable of each individual entity. Hope someone has tips or tricks to solve this!
  6. Hello I want to know if there is a way to create 2 different entities at the same source at the same time. I want my source to pick between 3 sets of entities when creating new entities. I have seen something similar in a simulation, where a man and woman was created simultaneously and the woman was assigned to a que while the man went to a server, but I can't find this simbit now. Please help me, thank you very much
  7. Hello Simio Forum I'm trying to create a model where I create 3 entities at the same time assign them to different routes and then batch them together again at the end of the routes. I got all the different processes at the different routes figured but i cant find a way to create the 3 different entities simultaneously. Hope that you can help, maybe the answer is obvious, thank you
  8. HELLO I would like to know if exist a way to sort decreasing or ascending a state variavel vector? Thank you
  9. Hello, In my model I’ve made entity arrival mode to be On event and I’ve created an event named CommandeEvent in the Definition ==>event section. In order to action the event, I’ve created a process called ProcessEvent in which I have a decide step followed by a fire step that fire the CommandeEvent if the condition in the Decide step is respected. But when I run the model, the entities are not created. Is there something I should do differently or add ? Thank you, Flora
  10. Hi! I try to modelize a production process. All my entities are of the type. But I want to give at each entity parameters such as height and length. I want that Simio generate it randomly in a state variable as an entity exit the source. My problem is the those parameters don't follow a standard distrubution as a normal ou triangular one. It follows time series (chronological series). Since it's a current pattern in production, I was wondering if there is a simple way to implement it in Simio? Thank you in advance! Pierre (I hope it's clear enough? Don't hesitate to ask me precisions if it isn't.)
  11. Hi all, I'm trying to do an information network model, and I need to have hundreds of thousands of "nodes" in this model, each node would need a source, server, and maybe a sink. And the "nodes" need to be connected to each other as well. Is it possible do create such "node" automatically instead of manually creating them? And would the runtime efficiency be okay? or should I switch to other simulation software/language? Any suggestions would be appreciated. Thanks!
  12. Hi, In my simulation model, I am trying to reach the steady state for the results. So, I run the model with 100 replications for 5 year but if I change the 5 years to 6 years, or consider a 1 year warm up time, or 2 years warm up time for the system the results will vary differently for each changes . The changes are small for example the total waiting time increase around 4 minutes when I consider 2 years warm up for the system. So, how can I make sure the simulation results are steady state?
  13. 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!
  14. Hi I want to change a state-variable of each entity of a specific type. I am trying to reach this goal by using a search-step in a Process. The process is executed correctly but the search-step is not doing anything. I have set the following values for the search-step: CollectionType: EntityPopulation Entity Type: Besucher Search Type: Forward Match Condition: True Limit: Infinity The goal is that each entity of Type Besucher should flow to the "Found"-Branch where I have created an assign-step for changing the state. But the Step following the "Found"-Branch is never reached and also the Step following the "Original"-Branch is never reached (I have set a breakpoint at thia steps.) I have also attached a screenshot. I hope, someone can help me.
  15. Hi I am defining a state variable. How can I see the value of that state variable at the end of the simulation in the results? Thanks
  16. How I can define a state variable only for the workers. For example if I want to check whether the worker had his lunch break or not. I am creating a dummy entity as lunch and it will call workers based on some schedule. I want to make sure the entity calls some worker which did not have lunch yet. How can I do that? The lunch entity will seize a worker from a list, however there should be a condition that makes sure the worker did not had lunch before. Note that I do not want to model this my setting the lunch hour in the off-shift period. The worker should be on shift and a lunch entity will seize the worker for one hour. There are 5 workers. 3 of them will have lunch from 12 to 1 and 2 of them from 1 to 2. I am creating 3 entities at 12 and 2 at 1. They should seize the workers and make sure they did not have not been seized for lunch before.
  17. Hello: I need to know a value from a state of an entity which is been processing into a server. I've attached a label, but I don't know the instruction to know this. Let me explain better, I have a model entity with a state variable called String, the Value is a Name. I need, when an entity come in into a server and this server start to processing, show this state into a label. Thanks
  18. Hi guys, I am trying to read origins and destinations out of an Excel file. To do this, I defined a process, in which I read the Excel file using "Excel Read", in which I read the origins and destinations and write them in the Node Reference State Variables ExcelOrigin and ExcelDestination respectively. After this, I created an entity, for which I assigned the Node Reference State Variables "ModelEntity.Origin" and "ModelEntity.Destination" to the previously defined "ExcelOrigin" and "ExcelDestination". Then I want to transfer the entity from Free Space to ModelEntity.Origin and set the destination using SetNode to ModelEntity.Destination. However, upon running the model, it states that "The value 'ModelEntity.Origin' for property 'Transfer.NodeName' is a null or undefined reference". It seems that it does not read the nodes properly from the Excel file, but if I change the input in the Excel file to a random number instead of one of the nodes, it presents the error of a data error mismatch; this makes me think that it does read the Excel file and sees whether or not the input are nodes. Is reading Nodes into a Node Reference State Variable from Excel even possible? Anyone who came across the same problem or has a solution? I have included my example in the attachment. Excel Read Node Reference State variable.spfx Input.xlsx
  19. Hello, Is it possible to change the state of just the entities while they are on a transporter? Because now i get an error when I put an add-on process to change the state of the entities going throug the node because simio tries to change the state of the transporter too. Thanks for the help, would really appreciate it!

  21. Hey all, My team is developing a model to simulate a network of electric fleet vehicles. We are hoping to track the number of cars parked at a charger in the model as a state variable (called NumCars), and then reference this value in the "processes" tab of the model entity, in order to assign individual cars certain values (called Signal). We have been unable to correctly reference NumCars in the Signal process within model entity. We attempted to use Model.NumCars to reference this value, but received an error stating: "Unable to get value of the property. Referenced definition type 'Model' does not match executing type 'ModelEntity'. Is there any way to reference a model state variable within a model entity process, as we are hoping to do? Thanks, Joe
  22. Hi guys. So, in my model, I have a table (binded to an excel file) with 2 columns - 1 indicates the real number that I want to assign to the state of an entity and the other indicates the probability of that assignment being made. So, I want to assign the values specified on the table, based on the probability also specified... Can anyone give me some hints on how to do this? Thanks.
  23. I assign a new state value after the entity leaves each server, and I need to keep those values. In a single run, I use the state observation log to track the value through the simulation. Is there a way to do that for an experiment? So I can repeat the run 100 times, and have the state value at each server for each run? Thank you!!
  24. I have a state vector where all but one indexed value must be zero. This oddball cannot be zero. I want to initialize it in the Definitions window. Can someone explain how to do this in a general sense? I.e., in general, what if I want to initialize every index with a unique value? Thanks
  25. How do you customize symbols? 1) You can use the built-in Simio Library symbols and you can easily make minor changes to them (such as changing the shirt color on a person), but you are limited in the changes you can make. 2) You can use the built-in Download Symbol links to Google (Trimble) 3D Warehouse to import any of those symbols into your project. Sometimes you want to do more customizing than this. But you can still do this with the following steps. 3) You can go directly to Google 3D Warehouse (http://sketchup.google.com/3dwarehouse/), select the symbols you like, and download the sketchup file to your local drive. Then you can use Sketchup to edit those symbols to meet your needs. 4) You can create your own symbol. It is pretty easy to learn enough Sketchup for simple editing. And with a little time, you can learn how to create fairly sophisticated symbols. 5) If you like the Simio Library symbols, you can start with the sketchup versions of the Simio Library, and again use Sketchup to edit them as needed. You can find these symbols at http://www.simio.com/downloads/public/SimioSketchupSymbols.zip Note that most of these are what is known as "low polygon count" (or simply "low-poly") symbols. Most of them originated from the 3D Warehouse, but have been simplified to make them smaller and faster to animate. If you want a better quality of image, see step 4. For steps 3-5 above, you can go to the Project > Symbols panel in Simio and Import Symbol, and do any final customizations before use. You can also save any of the symbols from above into your own library for use in other projects by going to the Project > Symbols panel in Simio then use the Save To Library feature.
