  1. 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?

  2. 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!
  3. 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
  4. A way of achieving what you describe here is to create Column 3 as String State Column. Then you can utilise the OnRunInitialised Process to concatenate the contents of Col 1 & Col 2 using an assign step as follows: Table1[1].StringState1 = Table1[1].StringProperty1 + "-" + Table1[1].StringProperty2
  5. If I were you I would define a storage element. Then, if the patients are finished with their loop I send them to storage (you can think of it as a waiting room). Then, when the vehicle is available I should check the storage (with a search step) and if exist get the patients on the vehicle. Does it work for you?
  6. 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
  7. Hello, guys, I do not know how to determine if a detached queue contains a certain kind of entity. I create an element station1 and a detached queue which sets the queue state as Station1.Contents. In Decide step, the station1.contents only returns the number of objects in the station, and I cannot use contains(obj) after station.contents, even though contains(obj) is a function for QueueState and Station.Contents should return the queue of entities currently located in the station, according to the help documentation. Is there any method to access the candidates or objects in the self-defined station? Thank you! Shu
  8. I am trying to create a model in which the worker is used to "batch" parts so they all move as a group of 8000. The issue I keep running into is that the worker just goes and delivers the parts as soon as they go on break instead of waiting till it accumulates 8000. Any help would be much appreciated. In this sample I provided, the worker should only be transporting parts at 100. Practice.backup Practice.spfx Practice_Model_trace.csv
  9. Hi LizMB, I have a few specific recommendations for you below, but generally I suggest looking into the SimBit models provided on Simio's Support Ribbon. A PDF opens with each model that contains a detailed description, so they are a great tool for learning specific approaches and techniques. A few that I believe are related to your particular problem are "Moveable Operator", "Interruptible Operator","Keeping Worker Reserved", and "Entity Follows Sequence". Worker1 carries both entities to their respective nodes and leaves them in their respective stations after worker(A/B) "checks them" (I used a delay to simulate this check) and then Worker1 moves on. For this objective, I suggest setting up your drop off stations A and B as a Servers. Use the Processing Time property to represent the "check" while seizing both workers needed (see the Operator related SimBit for more information). Make sure all entities are assigned a sequence, so Worker 1 knows where to drop them off. The worker(A/B) only picks up the entity if needed. So if the worker was with another entity in process (like Srv(A/B)), he would go check the new entity so that worker1 can move on, but would return to finish out the first entity to the end. Assign entities that enter the pick up stations a higher priority, and interrupt the Workers at SrvA and Srvb if a pick up task arrives (See Interruptible Operator for more information). Ensure that the Workers have the needed paths to travel to all of the destinations required in all directions. Currently, WorkerA and WorkerB cannot travel to the Outputs of the Servers. Other suggestions: Look into using a Timer Element that could trigger the entity creations at SrcA and SrcB. That should remove the need for Source1 and Sink1. If the Worker's travel doesn't need to be defined by a path, I suggest setting the Initial Travel Mode to 'Free Space Only'. The error message you are receiving is related to the Add-on Processes on the A and B nodes. Whenever Worker 1 enters either of those nodes the process is triggered and tries to complete the process with relation to the Worker. Restructuring the model with Servers in this area should help you get around this issue. Thanks, Ryan
  10. It sounds you need to use routing group elements. Just read about routing group element from help or look around for it in simbits.
  11. 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.
  12. Yeah it took me a while to understand the 2nd answer. What it means is that click on the source, then go to add-on process triggers, then select the “created entity” option so as to create that process. then you can follow the rest of the steps to create the actual process
  13. Hi all, I am wondering of there is a way to create something comparable to a"wait" resourcestate. Maybe by defining or monitoring the "waiting time" of a server. Thankyou in advance!
  14. Hi Jeff, I present another, and I think, a more compact approach in the attached model. In this model, I subclassed flownode object. And define a timer element in it. I also defined two properties in this subclassed object as Time_to_repair, time_to_failure. By this way you can use these properties to assign failure times and repair times after failure seperately. hope this helps! all the best, gocken Development 02_subclassed.spfx
  15. Hi Jeff, your model is ok. You can assign random variable's to timer element as well. By this way you can get random intervals. In order to work properly you only need to set timer2's reset event name property to timer2.event which in fact you have made this assignment at timer1 element. I attached your model with modifications. It seems it works as you intended. Hope this helps? Development 02.spfx
  16. To the best of my knowlegde every process can be enable or disable by using ProcessName.Enabled. You can assign this state variable true at the beginning of the three hour period (not a must but probabily using a timer element) and false at the and of the three hour period. I hope it works?
  17. You should use the timer element. Definitions-->Elements-->Timer. To see how it works quickly you should look for "timer" in sample simbit solutions or for a satisfactory explanation use help.
  18. 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
  19. The Simio product and its documentation is obviously created in English but we would like to expand that availability. Software As of this writing (April 2013) the Simio software is currently available in English and German. But the software has been designed from the start to be translatable. In fact we can quickly create a Google translation in any language, but unfortunately while that can be a good start of a translation, it's accuracy is not good enough to serve as a finished product. So we are looking for any volunteers who would like to see Simio in their native language. Textbooks We currently have book translations in Spanish (both books), Portuguese, Mongolian, and Italian. We are looking for additional translations and the translator(s) will be acknowledged as co-authors on the translated edition. Royalties will also be shared, but given the relatively small quantities and low book price your motivation should probably be mainly "fame and glory". Training and Other Materials Volunteers have also translated selected training and other supporting materials. We are always anxious to have this type of user participation to help the broader community. Existing and new materials will be available in this forum. Software Features A few features have been added to the software to make it easier to use in other cultures. One such feature is a setting to control the separator character used in CSV files which now defaults to your systems culture setting. Please let us know if additional such features are necessary. If you or your team are interested in helping with any of the above, please contact me directly. (dsturrock@simio.com)
  20. Hi All, I am using the write step in my logic but i am unable to write a string in csv, how can i do that? it is unable to convert element reference to string below is the error. Thank you.
  21. Process logic is typically added to a model on an as needed basis. For instance you will notice that some of our Scheduling examples, like SchedulingDiscretePartProduction (via Support ribbon -> Examples) does not use any process logic. There are several ways to initiate process logic which you could read more about in the "Processes" help topic. For instance, all objects in the Standard Library have an Add-On Process Triggers property category that allows you to specify specific points in the simulation that you would like to execute a process (like on Entered for a Server). A quick tip: you may double click an Add-On Process Trigger property (like Entered for a Server) to create a new process corresponding to that trigger. There are also other ways to initiate processes: using Elements like Timer or Monitor, user-defined Events, or the Execute step. I would recommend investigating these further in the help documentation if you are interested in learning more. One of our newest example models (provided in the software) called InfectiousDiseaseSampleModel demonstrates using fairly comprehensive process logic along with a data-driven approach. Happy modeling!
  22. 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?
  23. Good day, I have a tally statistic element that contains random values (in my case, the time to process an entity based on many factors which are also random). I was wondering if it is possible to access the values of the tally statistic individually, or in the broader sense, as I am trying to plot a curve from this single tally statistic. Thank you in advance. Eduan
  24. Set "log observations" property of tallystatistics element as true (under advanced options category of tallystatistics element). then at the end of the simulation you will see all individual observations from results-->logs-->tally observation log in a tabular format. If this not works for you then there exist other alternatives? Will you plot these values dynamically or statically (i.e., at the end of simulation)?
  25. Thanks Marco, I've just registered. However I'm a little bit confused on the time. It converts to 3am my local time from 17:00 GMT but the website timer adds up to 7pm. Can you please clarify this?
