  1. I've include my suggestion in the model attached. I assigned low priorities to each vehicle types. Then, select vehicles according to these priorities. It seems it works? SmallModel.spfx
  2. I do not know the details but if it is appropriate set "must simultaneously batch" property as true under the batching logic section. Then, add a "Release Batch Early Triggers" and set "Trigger Type" as "Event Based" and "Triggering Event Name" as Timer1.Event. Then, define Timer element and trigger it at exactly 9:00 AM.
  3. You should use data tables for creating such a large number of modelentities. You can populate your data table by binding it to an excel file or a database etc.. Then, examine the "Inventory Replenish" related simbits for how to increase and decrease inventory levels of each part. You can determine specific inventory replenishment policy accordingly as well.
  4. First rank the vehicles accoding to your preference in your node list (My vehicle first then the standard vehicles). Then, setting "reservation method" as "reserve closest" and "selection goal" as "preffered order" and "selection condition" as "Candidate.Vehicle.ResourceState!=1" will work for you.
  5. Drag and drop an ModelEntity into the facility layout. Then, select ModelEntity and see "Maximum number in system limit" property under "Population" section of properties window. Set this property as how many entities you desire throughout the simulation run.

    In fact everthing is ok except you did not placed the subclassed sink objects (mysink type objects) into the facility layout. Probably you forgot to drag them from the project library (at the left bottom window) to the facility layout. I attached the fixed version of the same file. Do not hesitate for asking more. cutoff.spfx

    Hi Nadere, I assume that in "Data" tab you have defined a data table. Select "Data" tab. From "Schema" ribbon insert a "State" type data column from by selecting "Property" dropdown list. Now, you should be able to include "Sink.StaNumberEntered" state variable. Do not hesitate for asking more.

    In the attached model, entities are dispatched according to some "Mysink" objects' inputbuffer entered cutoff values (predetermined values). I intentionally put these cutoff values values in the table to show how you can use state variables inside a table. Also, I intentionally place some steps seperately to increase understandability of the model. Due to having limited time I did not test the model. You can fine tune the model and develop it in a more compact manner. Time In System considering cutoff values.spfx

    First, you should define a "NodeReferenceState" on ModelEntity. After finding the appropriate sink to send use "set node" step to assign the found sink's input node as the destination node of the entity (ModelEntity.NodeReferenceState=input@sinkx). Then, do not use transfer step. Instead, set the entity destination type property of source object as specific and also set node name property as ModelEntity.NodeReferenceState. By this way each entity will find its own way via the links you defined.

    No, it seems your add-on process is working correctly. How do you transfer the entities to the sink? It seems there is not time advancement between creation and disposing the entities.

    place a delay step with a constant time (for example 5 minutes) in the same add-on process and examine the results?
  13. Because we assign the speed of path 3 and 5 to PathXXX.Contents.NumberWaiting at assign3 step of process 1 which is triggered whenever an entity enters node A. As I said in my previous post this expression may not serve your purposes. This is only for illustrative purposes. Here the message is you can increase all existing entities' speed (but all of them at the same time) on path 3 and path 5 whenever the process1 is triggered. Also, you can trigger process 1 by using monitor elements (which seems more suitable for your purposes). For example, using a monitor element you can track the number of entities on each path seperately and whenever this value crosses some treshold value (got congested) you can trigger process1 using monitor element. Note that in your attached model status labels shows how many enitities exist on each path. At the end, change the assignment expression of assign3 step of process1 accordingly.
  14. As far as I know you can not accelerate the speed of an entity on any link? you should use tricky solutions to overcome this difficulty. One of the trick is setting the speed of entities to infinity right after entering node a. then changing the desired speed of path 3 and path 5 to some meaningful values. In the attached model this trick is applied. Note that the assigned values (i.e., Path3.Contents.NumberWaiting) should be replaced by any reasonable values. This assignment is only for illustrative puposes. Note that by this way we made the speed of modelentities limitless but at the same time we limit their speed with the speed of paths. you can do any other tricks as well... One of them maybe changing the type of the modelentities right after entering path 3 and path 5 (say path3_modelentities and path5_modelentities) by creating a copy of the associatedobject. Be sure to destroy the original one. And then whenever you need to increase their speed you should search their population by a search step and then assign appropriate speeds to them individually. These are the ones that come to my mind at the moment, but you can find some better methods by pondering. EntitySpeed4_me.spfx
  15. The best way to collect such an statistic which belongs to modelentity's is to assign it to a model state variable. You should determine when to collect them appropriately. In your case it seems you have just two points to collect this statistic. 1) when it arrives its destination(s) (total loaded delivery distance) 2) before destroying it (total loaded and unloaded delivery distance).

  16. There may be some calculation errors in your model. Pls compare the attached model's results with yours. Apoteksimulering (1).spfx
  17. Define incoming patients' admission to hospital dates as a "DateTime" Property in your table. And set "Arrival Mode" of Source object as "Arrival Table". Then, set arrival Time Property as "DateTime" property you defined. This will provide creating entities according to their admission to hospital times.
  18. For data tables approach examine the model: https://drive.google.com/file/d/1evwTU-ggxEVCrrksClctNoHhMakEhi4V/view?usp=sharing
  19. There are a few ways to achieve part/path matching. You can see the simplest one in the model I shared via the link below. https://drive.google.com/file/d/1Uoi6Lt1vdw095tHWTwTd6Azk_95fXmu_/view?usp=sharing If you have many entities and paths you should use data tables approach.
  20. I can not upload the file. Try this link: https://drive.google.com/open?id=1D548lj3OsccGzFRn77m7J_UZ9dueG_TE
  21. I hope the attached model works for you. It seems there is problem while uploading. I will try again later.
  22. I think the problem is not so hard. Contact with technical support (support@simio.com) they will solve this inconvenience quickly.
  23. Jeff's solution is elegant and enough. Still, I liked the way you handled the problem via processes. You need not to define Stopcreatingentities event to fire. I revised your logic and attached its revised form as a png file (can not saved my changes due to having a different version of simio).
  24. Dave had shared a post which, I think, can be a solution or at least a starting point to your problem. Here is the path to that solution: https://www.simio.com/forums/viewtopic.php?f=36&t=2334
