  1. The SkyBox icon on the View Ribbon opens a library of static and dynamic scenes that can be placed in the 3D animation. Dynamic scenery includes several options for clouds that move with the animation as the model runs. Typically, the Speed Factor should be set to 5 - 10 or greater to see movement. Static skybox options include many indoor and outdoor scenes. Indoor applications include adding building walls to surround your model. The 'None' option will remove any existing skybox. Users can create their own SkyBoxes as well. The “library” skyboxes are simply *.zip files with images inside the
  2. Hello, I'm using a model made by a group of studens one year ago. Their model is pretty simple but I'm facing a strange problem. Whenever I open the model the following text appears in a warning message: "You may no longer save, copy, run experiments, run plan, or run risk analysis. Runtime limits exceeded: 285 steps in the model (limit is 150)". I've searched in the Simio Forum but it seems like there's no other case like that. The model has no processes so, there are no steps. I really don't know what's happening. I'll appreciate your help with this case. Thanks in advance,
  3. Hi gocken, Thank you for your reply and your attention to this problem! The current method that adds a breakpoint after 'CallMATLAB' function works in my project. Before Simio runs MATLAB, Simio will send out needed data to SQL server and then call MATLAB function. MATLAB receives the data through the database, implements the algorithm, and writes the data into the database. The Simio program pauses at the step that Simio reads the MATLAB results from the database. I have validated the .dll file with a simple MATLAB program that plays a music file and it works. Because the Simio
  4. Most probably secondary resources will work for you, support here!. I can not open your model since we are using different editions. If we were to use the same edition I was able to open your model. Thus, while developing models which you will share with someone else you should consider this constraint.
  5. I think secondary resources is exactly what I needed. If not, I'll be back to the forum. I'm surprised the model didn't open. ModelForQuestionCOPY5v.3.spfx
  6. I was not able to open your model. Thus, can not say anything for sure. But, did you try other resource seizes/releases option under secondary resources of server object? It seems it suits your needs?
  7. Dear Simio Users I'm modelling a system with 1 source, 1 waiting list, 6 servers and 1 sink. But at the beginning only 3 of the 6 servers are available. As soon as these 3 servers run out of capacity, the remaining 3 servers should "open". Is there a simple solution to start my simulation with an initial stock in the 3 servers and on the waiting list (which is modeled as a storage)? Since the entities have several state variables, I should also be able to define them at the beginning... Or does it make more sense to solve this problem with a process
  8. Hi - My model has a vehicle that is going 'on demand' through a network of paths. It picks up items and people for delivery. I need it to pick up as it sequences other nodes enroute, so each trip is efficient. I am getting errors in my Add On Processes. Once the vehicle is loaded, I define the current capacity as the model capacity minus the loaded entities. And then once the vehicle sequences another node, I'd like it to add entities up to the open number of seats. Could you please take a look? Current.For.spfx
  9. Hi Jeff, You can use a Resource object to model the unplanned failures and repairs of a crusher or conveyor. The Resource object has unplanned failures built in, and furthermore, can accommodate a shift pattern. When the resource fails, close the flow node and when it is repaired, open the flownode again. I have modified your model to illustrate this concept. There was custom Flow Library shared in the past that contains a "flow server". Basically an object such as a server, but that can handle flow. Development 03.spfx
  10. Hello, I can't open your model either. If you can send some screenshots of the properties, that would be great. Thanks
  11. Hello, I can't seem to open your model, but here is a simple example to illustrate updating flow when processing starts or ends. You can change the rate of flow through the flownode by applying similar state assignments using the Output@Tank1.FlowRegulator.CurrentMaximumFlowRate expression. Dynamically Update Flow.spfx
  12. I have attached a simple example of one approach. 1) I edited the ModelEntity object and added a state array of type MatrixFromTable. This type of array is automatically initialized from a table. Ideally I might have also added a table to the entity, but Simio doesn't work that way. Instead, I added a RepeatGroup named InitializationValues consisting of a Real property. I used this repeat group as a way to essentially add a "table" into the object, since internal to Simio there is almost no difference between a table and a repeat group. 2) Back in the model I added a table and then i
  13. Open your ModelEntity and add a new Real State variable named TimeInServer1 or whatever; Set ModelEntity.TimeInServer1 = TimeNow when the entity enters Server1; Set ModelEntity.TimeInServer1 = TimeNow - ModelEntity.TimeInServer1 when the entity exits Server1; Set Server2 processing time to ModelEntity.TimeInServer1 * E + delay (hours). Check the attached model for some extra help. Register Server1 Processing Time.spfx
  14. It is possible. There's several ways to solve this. It is just a matter of model designing. Some tips: 1. You can use expressions like TimeNow or ModelEntity.TimeInSystem to check how much time processing time has passed. 2. Interrupt step might help you remove the entity from the process. 3. A State inside the ModelEntity will help your entities to take the right path or take the right decisions. Open you entity model, create a boolean state named Failed (or whatever the name you like), set ModelEntity.Failed to True or False, and use this same expression to steer you enti
  15. In that picture yes most of them were closed (tanks 2-4 have a 0 next to them). I did find that the monitor wasn't triggering correct and fixed that so it gets a little further but now stops at this point with the flow nodes all open: I do have a an execute system flush step that gets executed to enable all the flow nodes. I will continue to go through the model trace to see if I can find something in there.
  16. Create processes that are triggered by YourTank.Full and YourTank.Empty events and set the Output@YourTank.FlowRegulator.Enabled to True or False to open or close the tank's valve. Silimar to how I did in this other post. Also, Output@YourTank.FlowRegulator.CurrentMaximumFlowRate might be useful if you're having trouble your tank's flow rate. Keep us posted if you need more help.
  17. I ran your model until the warning occurs and then examined the Content and Throughput categories in your Results Pivot Grid. I didn't notice any alarming buildups in any of the Combiners, Conveyors, or Servers, but the Entity statistics appear unusual: None of your 3 entity types ever exit the system. Your problem is with creation of too many empty pallets. Another thing I noticed that could be the main problem is that your Empty Pallet source creates 6 empty pallets every .25 minutes, with no limit. When I converted this to a just-in-time (Event Based) creation the entit
  18. Hi Tom, thanks for your help! I've found a solution on my own in the meantime (probably not as sophisticated as yours but it works well). I additionally modelled a small version of the lift itself and created a wait process. The triggering event is "vehicle exits Node X". I used the process for my servers ("after processing"). So whenever a chair exits the node, the gates will open. This is actually quite close to reality where the gate opening interval is not fixed but depends on the speed of the lift and the point in time when an empty chair arrives. All the best, Nico
  19. Dear all, I am currently working on my master's thesis. The goal is to simulate the waiting line in front of a chair lift at a ski resort. I may have future questions, so I hope we can keep this topic open for other questions on the same model. I started adding objects and need to set the properties for the servers now. Currently I am struggling to find the correct setting that allows me to process entities at a fixed time interval. I want the red barriers in front of the moving walkway to open every 7.2 seconds (interval between two chairs). The servers are called "Schranke" in my s
  20. We try to simulate that every entity, gets a place in the que for either OTC or Prescription and a place in a mixed que. The customers is then called to the cashier when they either is first in que of mixed (cashier1) or first in OTC-que (cashier1) or if the third cashier is open, first in the mixed que. We have tried to combine your aswer with the ranking rules in the server, but it doesn't seem to work since our cashiers (determined by: capacitylogic) doesn't close when no one is waiting over one minute. Is it a wrong way to combine it to get the system as described above?
  21. Hello, We want to assign the entities to different servers. The first server has FIFO selection system, and the second has FIFO with entity type OTC as the first priority, and the third server has FIFO. Furthermore, the servers open and close sometimes, but the entities keep transfering to the closed server. How can we divide them after the described rules? We have tried to get the output node to select from a list of nodes with the input of the different servers, but then the entities always choose server1. OTC-and-prescription-model.spfx
  22. I have been utilizing SIMIO for a couple of months, but I am still relatively new to some of the features. One of the problems that I have recently encountered in my simulation is entities taking a path even when the receiving node (a separator) has an off shift rule. Specifically, I determine the availability of the separators based on 5 minute intervals with a TimeIndexedRow table reference. The attached image accurately represents my dilemma while simulating an airport checkpoint. The passengers are first processed in Server 1 and subsequently proceed into the paths leading to either
  23. As you indicated, you can open and run an RPS or Enterprise model in Professional or Team. But Professional/Team is NOT designed as a "run time" version for scheduling. You cannot see, change, or take advantage of the scheduling-specific features. But I believe that you could change the model, save it, and reload into Enterprise and I think you will not lose any Enterprise features.
  24. Thank you. I used another computer which doesn't have enterprise version simio to open it and it's helpful... I did't know 'Is.xxx' function...
  25. can't open your models. SInce i'm using commercial version/enterprise version... It says commercial version can't open academic/personal version model...
