  1. I am trying a simple assembly process where 2 entities are to be assembled to create a 3rd Entity. Hence I need to destroy 2 entities arriving at the server and create 3rd pre-defined entity. Can someone please help with how this can be achieved?
  2. I am working on a simulation of a number of firms processing raw products. If I represent the firms as resources in a server -so that the server capacity represents the number of firms, how could I identify which resource/firm processed a certain batch of products? Can this be done with a server having a capacity of its own, or should I use a pool of (secondary) resources with id labels so I can use that id to label the product batch?
  3. I'm very new to simio, so I appreciate any and all help. Learning this on my own without an instructor to help at the moment. I have the model shown below. I've defined a sequence table so that it should flow from Source1 -> TransferNode4 -> Server2 -> TransferNode3 -> TransferNode2 -> Server8 -> Sink1. It primarily follows the sequence but occasionally one will go to Server1 then hop down to Server2. Why is it doing this and is there a way to stop this? Thanks!
  4. Here is a simple utility that will export your model to a text file (pipe delimited). Then you can modify the file and import the model back in. NOTE: Currently, this utility does not handle graphics in your model. There is also has capabilities to import and export lists and networks. Here are some quick instructions on how to setup this add-in. 1) Download the "ExportImportModelAddIn_DLL.zip" 2) Extract "ExportImportModelAddIn.dll" from the "ExportImportModelAddIn_DLL.zip" into a temp folder (e.g. c:\temp). 3) Right-click the assembly and select properties. Then choose to "unblock" button and press apply. (only needed for Windows 7 and later). 4) Copy "ExportImportModelAddIn.dll" into "C:\Users\<YourUserName>\Documents\SimioUserExtensions". You might need to add the SimioUserExtensions folder under MyDocuments (C:\Users\<YourUserName>\Documents) if it does not already exist. (e.g. C:\Users\GlenWirth\Documents\SimioUserExtensions). 5) Open Simio and load your model. 6) From the Project Home...Select Add-In button, select "Export Import Model" 7) Choose the function that you want to run (e.g. Export, Delete, Import, etc..). Note...If you export and then import the model without a delete, it will update the object data if the object already exist. Updated 2018-11-08....Added Export To CSV, Export To DB and Import From DB. Export To DB will create a table in the SQL Server database with the same table name as the table in Simio. Te data columns will be of type nvarchar(max) and the default value will be the same as the default value in the Simio table. It is assumed that Simio desktop will still do the data validation; not the database. This feature is used to save the Simio data into a database so it is backed up and can be shared across users. Each time the Export To DB, if the table already exists, it is dropped and a new table is created. This ensures that the data schemas match between the Simio model and the SQL Server database. Updated 2017-12-05....Fixed index issue with links import. Updated 2017-09-25....Fixed the import of lists. Updated 2017-07-14....Added the ability to auto generate and auto read files. Previously, the files need to be created prior to running the add-in. Now, they will created by the export. Also, the import will retrieve the same file generated by the export. These options are available when the "Auto Generate and Read Files" option is selected. Updated 2017-07-13....Added the ability to multi-select options. Now, more than one option can be initiated when the OK button is selected. This will streamline the process of exporting, deleting and importing. This tool is very helpful for testing out your model with various configurations to ensure that runs properly under various object and/or data configuration. Updated 2017-07-11....Now supports exporting and importing of model properties, exporting and importing of table properties and delete table data. Updated 2017-06-22....Now supports exporting and importing of data tables using using XML. This is simple way to export all the table data from one model and import the same data into a new model (assuming that the same tables schema exist in the new model). Updated 2017-01-27....Now supports exporting of object types using XML. This can be used with the new Configure Scheduling Resources in Simio 9.150 capabilities to define your own object type properties based on an XML document. Updated 2017-01-23....Now supports exporting and importing objects using XML. When using XML, property units are also exported and imported back in. Updated 2016-10-24....Updated files...Added support for repeating properties. ExportImportModelAddIn_DLL.zip ExportImportModel_Code.zip
  5. Hi, I have used the SimBit "InterruptibleOperator" where i have set the process time on the servers to be a fixed one (200 sec at server 1 and 300 sec at server 2). I have further more changes the Interarrival time on source1 to be 1 day and the entities per arrival to 50. The Interarrival time on source2 to be 1 day and the entities per arrival to 100. (Look at the linked file) Then when i checked the process time on the server in results it was not 200 sec and 300 sec as had set it to in the server. I think the operator is the one to blame for this, but how can i get the right result in results? I have tryed to remove the operator and the process connected to it, and then i got the right process time. I however still need the operator, so need a solution to get the process time and keep the operator. InterruptibleOperator - process time - resultat1.spfx
  6. If you want to experiment with different number of resources (or servers) you can create these objects automatically by using auto-create functionality. This will save your time and simplify your progress.
  7. You can use seperate servers (each has 1 capacity) each represents individual firms. Create entities (raw products) via a data table where you should also include one column (a node property from object reference property) to represent where the created entity will be processed (as its destination). Then at the output node of the source object set entity destination type property to specific. Then set node name to Table1.NodeInstanceProperty1. The entities will be routed appropriately.
  8. Hi all, I was wondering, is it possible to record the time in system of entity instances and subsequently plot the values in a histogram? Of course, I can see the average, min and max values in the results tab, but I am interested in knowing what the distribution is like for model validation purposes. If it is not possible to plot the values in Simio, is it perhaps still possible to access and export the values, i.e. to a .csv document? Hopefully my question is clear. Best regards, Michkel Mariegaard
  9. Hi I want the selection weight of the paths to change by the entity type. Ideally if it can be chosen from a data-table. Example: From server1 to server2, server3 and server4 PartA - server 3 Weight 2 server4 weight 8 PartB - Server2 weight 3 Server3 weight 4 Server4 weight 3 Can someone help me to find a solution for it? Thank you!
  10. Hi, I'm currently working on the attached model, and currently i have a lot of trouble on making the two operators prioritize the B2C entities. I hope that somebody can help me fix this issue. Just a brief rundown of the model: each day freight arrives at 8.00 and this triggers the sources for B2C and B2B to feed a number of entities, with a corrosponding distribution into the system. Upon the entities arrival to the two "AT-servers" the two operators should prioritize the completion of all B2C entities, before moving to ATB2B. If new entities arrives at the ATB2C server, and the operators is situated at ATB2B, they should interrupt that process and focus on ATB2C. The prioritizing and interruption is based on the simbit: InterruptibleOperator.spfx Best regards Kasper MySimio.spfx
  11. Hello everyone, I am a master's student in operations management trying my hand at Simio for the first time. I want to develop a model that simulates the delays incurred by variable supply lead times which may lead to stock-outs at a manufacturing plant. I would like to model demand so that each entity generated by a single source module corresponds to a sales order. Each order should have a probability to include orders for several specific product types (since sales orders may contain orders for different product types). As such, entities should have an arrival rate which corresponds to the arrival rate of orders at the company, and the product mix of each order should reference the probability of a given product type being included in that order (i.e. product A has 25% probability to be included, product B has 50%, etc.). Is it possible to do this? I would also like for each product type to be associated with a specific BOM. I.e., a server module should reference each entity instance to consume material as defined by the BOM’s of the products stated by the entity instance. I have defined each component as material elements and defined a BOM for each finished product that references the materials needed. However, in the server module I am only able to input a specific type of finished product as material requirements... Your help is greatly appreciated!
  12. Hi everybody! I want to know if it is possible that an entity can change from one server to another if the another server is available and the entity isn't still processing. It means if it is possible that an entity can exit from the input buffer of the first server. Thanks for your help. Best, Albert.
  13. Hello together, would be very thankful for any advice: I have a sequence table with sequences according to their workstations: A - B - C - D If I only have one operator, they can just be done one after another. If I have 2 Operators A and B can be done simultaneously to C. How can I model this? The problem is probably, that the entity (batch) has to be splitted to let workstation A and C run at the same time. I tried it with process-add-ons like creating a second entity and transfer it to Station C. There might be a much easier solution?! Thank you in advance!
  14. Let's say I want exactly 100 entities arrive where the arrival of each one follows a normal distribution with mean 1 hour and standard deviation of 5 minutes from the start of the simulation. How can I model that within SIMIO? The interarrival time doesn't make sense because I don't know / care what the interrarrival time between each entity is. I realize that I could randomly generate 100 normal random variables outside of SIMIO and input them all as an appointment, but I am wondering if there is a better way especially if I want to do many replications with a different set of 100 random variables each time.
  15. 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 entity to the right direction. 4. Be creative. Your solution heavily depends on your problem.
  16. I have an entity type. 50% of that entity is one counter type while the other 50% is two counter type. After the entity exits the server, 50% must exit while the other 50% must go to the second counter. How do i do this thanks
  17. Hi, Have an issue relating to trying to track a segmented entity with the camera. I've attached a very simple model that demonstrates the problem. As soon as i set the draw type to 'Segemented' the camera tracking just doesn't work. One possible solution i am aware of is to simulate the segmented object as individual entities. In the context of what i'm trying to do this creates a lot of additional complexity that i don't want to address. Any other bright ideas? Thanks, Lucas Camera Tracking Segmented Entity.spfx
  18. New to Simio and learning as I go. The attached model includes a CombinerNode1 that batches entities in groups of 2 & 5 (random.discrete). I would like Server1 to use different processing times for the different batch sizes. For example, a batch of 2 entities should be processed in 5 seconds; Batches of 5 entities in 7 seconds, etc.. Eventually I will create batches of up to 6 entities. I have tried using Server1.Processing.Contents for Processing Time, but seems to return the value of 1 all times. Any help is appreciated! Thanks! Processing time based on BatchSize.spfx
  19. Hello, I am fairly new to Simio and having a bit of an issue trying to understand how I can create the pull down option for "ModelEntity.Row", when trying using an "Assign" step to set the Entity Weight. I hope this makes sense and I have attached a few pictures. The first is a screenshot of my process in the simulation I am working, and as can be seen I do not get an option that reads "ModelEntity.Row" and/or "ModelEntity.RowOreWaste". the last two pictures are from simulations I am using as reference when creating my process and simulation model. thank you
  20. I want to set a timer that represents "time of failure" where if the entity is not processed within this time, it will be deemed a failure and be destroyed. This time needs to be dependent on a random draw (one for entity type, and one for a distribution based on entity type). I also need to be able to change this time due to interventions that happen. Is it possible to do this?
  21. Hi, I have a source with a rate table, it is set to make an output of 100 entities every day. The problem is that the entities comes out one at a time trough that day, but they should all arrive together at the start of the day, so that the servers has the whole day to process them.
  22. Hi All, I have a query. Is there a way to implement logic that allows the model to vary the processing time of a server as a function of the available man power? In my model I have various servers and all need a specific number of workers in order to begin processing. I have one large pool of workers to be shared between all stations. This means that there are times when all the workers are in use and times when some are spare. Ideally I would like to model that when there are men spare they would come and help other stations and get the job done quicker or when only some of the required quota of workers are seized they can start the work all be it at slower pace until the full quota has been seized. I hope this makes sense Thanks
  23. Hello, I have tried to make a table with reference to two entities and their process times, but when I go to Model.Process to model Begin - SetTable - End, I can not find the SetTable step beneath all steps. I have looked at the youtube video named "Simio Simulation Sofware: Referencing entity data in Data Tables" I don't want a product mix as used in the video, because I have a rate table for each entity. The system consists of one the following, reference to the photo below:
  24. Hello Can simio use time series data (say from an excel file) as cost input for servers, that updates every hour?
  25. Sorry if this is obvious, but can someone tell me how I can reference the number of batchMembers in the example above without having to reference the specific entity, which in this case is TruckLoad.5442. I need something like "the number of batchMembers in the entity currently in the ParentInputBuffer" please. e.g. TruckBay1Batch.ParentInputBuffer.Content.???.BatchMembersCount? As you'd expect, this number changes constantly during the simulation run. At this moment of simulated time, the answer is 2. Thanks for your help!
