  1. I have a data table which has several rows that contain node and some other infomation. I want to move a transporter to a node in that data table and park at that node. Now I have my model and data table like this: In this model, when I click the move button, Myvehcile1 will move to TransferNode1 or TransferNode2( depend on some inputs for Myvehicle1). The problem is because I don't create any ModelEntity, I seize Myvehicle1 by itsself. So, Myvehicle1 is in its visitrequestqueue and it will never stop at a node and it keeps moving between nodes. Below is the process I create to find the node in table and move the transporter. The model file is also included.SimpleModel.spfx Does anyone know how to achieve my goal? Thank you very much!
  2. You can use SetRow step in process logic to set a specific row reference in each table. If you don't know the specific row in each table then you can use Search step to find a row in the table and then use SetRow. Once you do SetRow, you will have row reference to the table. If you have conflicting row references then you may have to cancel previous row references when you do set row. You can do that using Advanced Options on the SetRow step.
  3. My model currently reads tasks from a table and I am trying to model material consumption. For each task there are groups of materials: A, B, C, and priority values: 1, 2, 3. To complete a task, only one material type from each group A, B, and C must be consumed, and the order they are consumed in should be based of the priority. For example, if task one had entries like the table below, if all materials were available, materials 1,4,6 would be consumed. If material 1 was no longer available materials 2,4,6 would be used, and if material 6 was not available the task could not be done. The material requirement section in the processing task editor does not seem to support groupings and priority and was wondering if anyone had an idea on how to accomplish this. Task MaterialName Group Priority Quantity Task1 Material1 A 1 1 Task1 Material2 A 2 2 Task1 Material3 A 3 1 Task1 Material4 B 1 1 Task1 Material5 B 2 3 Task1 Material6 C 1 1
  4. Hi Folks, We have a data driven model where entities require a value from a table with n named columns. For example, consider the column names might be "Group1", "Group2", and "Group3". For each randomly selected entity classification based on a random row for example, we wish to randomly select which column to grab a numeric value for that type entity. Each Type has a unique distribution of amounts in the table. Suppose an entity has a string state called MyGroup, and I set that value. For example ModelEntity.MyGroup could be set to "Group1". Is there a way to use that name as a reference to the named column in a data table? I was thinking something like ModelEntity.MyValue set to MyTable.(ModelEntity.MyGroup) would be nice if it worked, but it does not. Is there any way to use that string state value as a reference to a named column in a desired table? Thanks So Much For Any KindThoughts On This, Jim
  5. I am interested in using task sequencing reading from a data table to solve my issues with multiple tasks being done by different workers at the same time and task precedence. After looking at the simbit related to it (TaskSequenceandWorker) I did not see a way to add probabilistic and conditional columns like when it is done directly into the server. Also is there a way to have a column for entity types and have it only reference rows that are assigned to them.
  6. We are currently working on entity routing through a medical facility. There are individual servers that represent areas within the facility where patient type, current location, probability, and destination (Input node of next server) are all in one table as one column each. After processing we want to subset the table to only have the specific ModelEntity type, correct current location, and then use TableName.ProbabilityColumn.RandomRow on the subset table to find the destination location. We have not found a functional way to subset the table.
  7. I'm currently creating a model of my local public transportation system. I have calculated the arrival rates for entities in 30 minute intervals (the arrival rate will change every 30 minutes). Is it possible to create a schedule that allows the source block to change the entity creation rate every 30 minutes? I would also like to create a different disembarkment percentage for each station (sink) to unload passengers based off my collected data. Is it possible to allow the "Entity Destination Type" to assign a percentage to each entity designating which stop it will get off i.e. 50% to get off at stop 2 and 50% to get off at stop 3? Any information or similar modeling techniques would be greatly appreciated.
  8. Hi All,

     

    I am trying to look as to how can we create experiments with various schedules in the SIMIO experiment tab.

    Currently I am not using RPS version.

    I have created a schedules for various servers using Simio process logic and schedule table for each server.  I am able to run one schedule and see the resulting performance, but it would be interesting to see how the changes to the sequence of orders changes the performance.  How could I set up experiments to make changes to the sequences in the tables?

  9. Is there a way I can concatenate string in table for e.g. Col 1 of table 1 has name "Simio" Col 2 of table 1 has name "Simulation" I need to create col 3 in table 1 that says "Simio-Simulation" One way is I do it outside Simio and then import but don't want to do that
  10. Hi Jim, Unfortunately, at this time, there is not a way to reference a column name with a string variable. The column needs to be directly specified by name (like MyTable.ColumnName) or you could specify the cell by the table row and column index (like MyTable[RowIndex, ColumnIndex]). The indexes can be State Variables that evaluate to an integer. The caveat is that you can not just specify the column index, the row index needs to be there as well. So assuming you can assign the row, one approach to consider is creating an integer State Variable to save the column index. A Math.If expression could check the group name string, and assigns the integer variable the corresponding column index. Then place the integer variable in the Table column Index. Happy Modeling! Liz
  11. Hello! One suggestion is to use Key/Foreign relational tables to accomplish your goal. If you have a table that defines your unique entities, you could then set the entity column as a Key. In the Task Sequence Data Table, you could then add the Foreign Key column to specify which rows pertain to the specific entity. This could limit which rows in the Task Table the Entity will have a reference to. Happy modeling, Liz
  12. Dear CWatson Is this functionality already available? Or maybe you have another idea, how to solve the following problem?: I'm looking for a solution to use the name of a data table as a state of my entity. I have 3 data tables that contain the same parameters but with different values. In the beginning of the simulation, I need the values from Table1 and after a certain time the values from Table2 and in the end those of Table3. How can I choose a table based on the state of an entity? Alternatively, I could merge the 3 tables to one and use multiple columns instead, from which I have to choose based on the state of the entity. But also for this topic I haven't found a simple solution... Thank you in advance for your help! Regards, Sam
  13. Is there a way to create a column of Time property without date using Simio Table, just like the start time and end time of day pattern of the work schedules? The work schedule doesn't suit my needs.
  14. Hi Ryan, Thank you for the corrections. As always, spot-on advice, that is very appreciated. I do have a few follow up questions. - Do I set the Initial Sequence property to 'Sequence1' or do I need to tell it the row too? 'Sequence1.Sequence'? Sequence 1 is working, but just wondering. - In the SimBit, Entity Follows Sequence With Relational Tables, there are three types of Entities that all flow through the same source with the Source Property, Table Row Referencing, pulling from the JobTable with the Row Number 'JobTable.ProductMix.RandomRow.' For my model, I have two different entities and the source Bldg is supposed to pull BOTH entities with the Table Row Referencing, "JobsTable" with Row Number: "JobsTable.NumberWorkers.RandomRow." But when the model is run, only one entity is ever used. The Table has an ExpressionProperty of Random.Triangular(3,6,9). Is that the problem? The SimBit's table was an actual number. I tried replacing the Expressions with actual numbers and the Entity switched to use the other one but I am still not able to get half the 34 to be one Entity and the other half to be the other Entity. - How do I get the Vehicle to carry its max capacity? The capacity is set to 6, and it only carries up to 4 entities around at any time. This is incorrect, as the Entities are supposed to be grouped into work teams of Random.Triangular(3,6,9) for their initial Source output move. Afterwards they can be individuals or work teams. The Bldg has the Entity Type defined as the JobsTable.Specialty so it should pull from one or the other (like the below mentioned SimBit), and the with Entities Per Arrival Set at 35; and the Entities themselves are set to a population maximum of 17 each and I get a Runtime error of maximum number exceeds limit for the entities. Why doesn't it hit the limit and then pull from the other Entity? - I'm confused about the network you mentioned above. I thought the nodes had to be linked directly (output to input node). So the busy nodes have a lot of paths radiating out from them and it makes it a little messy. Is there a cleaner way to show the routing? Thank you,
  15. Hello, I have a Arrival Table, but I only want to create Entities of a specific part of the Table based on a property. IntCol Entity 0 A 0 C 1 B 1 c So, the source should create all entities with a certain integer in column 'IntCol'. The integer value is assigned by a referenced property that I can experiment with different parts of the ArrivalTable For example: If Property == 0 , create only A and C in the source. How can I do that? All the best
  16. Hi Mirek, I think the problem here is your setting arrival mode to arrival table. I am not sure but after generating right entity the source object then assigns it row according to the arrival table which means row 1. Then the right entity (B) follows the wrong task sequence. Try by setting arrival mode to interarrival time. This time it should follow the right seqeunce. I will try other options and inform you if I get any other solution.
  17. 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
  18. To answer your question specifically with regards to the MultiEchelonSupplyChain example, the OnReplenishOrder process that you see in the process logic of the data table driven example is automatically executed by the Inventory elements when the inventory detects the need to replenish. Go to Definitions -> Elements and click on the Inventory elements and you will see where that process is being referenced. The ShippingReceivingLogic process is being executed when an entity enters any of the BasicNodes placed in the Facility View. For example, click on the DistributionCenter node and in the Add-On Processes -> Entered property you will see the name of that process befiling referenced. The TryFulfillOrder process is executed by the OnCustomerOrder process using an Execute step, which is in term triggered by a customer order arrival. Note that If you are trying to figure out where the name of a process is being referenced, you might go to Project Home in the ribbon UI and go to the Search window. And then search for the name of the process in the model, and it will show you the locations where it is being referenced.
  19. 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!
  20. 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.

    Hello, everyone! is it possible to use a Look Up Table and Rate Table to the same time in the source in SIMIO? Let me know if you know a way to do that, please. Thanks for your help!
  22. 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.
  23. Hi, i am new to Simio and I want to model an Airport terminal operations, i have the following questions? - which is better to model the check in counters have the same properties as single server with a certain capacity or multiple servers? - how can i change the check-in counter capacity based on the number of entities in a single queue( queue is on the path and not the server input buffer) - My model is using arrival rate table to generate the passengers, How i can model the passengers destroyed at the Gates based on flight Schedule (Departure time) ? Thanks
  24. Hi, I want to have a source that creates entities according to a date. But also, I want each entity to carry some information like Code, Processing Time and Type. It is possible to do that? And After, how I can use the information that each entity carry? For example, Each entity has their own processing time (according to the table), how I can use that procesing time in a server? Thanks for your help!!!
  25. Hi M_A, Just setting the Sequence property to 'Sequence1' should be enough since you set up relational tables. Because you have Maximum Arrivals set to '1', it is going to produce 1 entity type. I would switch your Maximum Arrivals to '35' and number of entities per arrival to '1'. You will also need to set your interarrival time to '0', so all 35 show up at the same time. It might be best to use a second Source object to create your second shift. I would increase the length of the Ride Station Queue in order to see all 6 passengers boarding the Vehicle. I think the network is fine, but hard to debug. Be sure all travel destinations for the Vehicle are possible. Thanks, Ryan
