  1. How can I model where the robot always pick 2 parts and waits until 2 parts are available at output buffer of the server. (Robot is available in extras library). i have multiple servers in the model.
  2. Hi All,

    In my model, I have a transfer node and the entity could go to either of the next 2 serves as in the picture.

    I have assigned product number(1,2,3...) to entities …., if product “1” moves from transfer node to S1 and the next product is also “1”, it should also move to S1 and if the product number changes its should change the server to S2. So the entire batch gets processed on one server.

    After processing from S1 and S2 the entity should flow in batch so that at S3 I have batch production

    Right now the entities go based on “By Link Weight” and randomly goes to the server which affects S1,S2,S3 servers setup time

    Any thoughts how can that be achieved, I do not want to setup a sequence table.


  3. Hi Jon, let me know if this helps. I added priorities to entities and changed the dynamic selection. Unmesh Model_worker.spfx
  4. Hi All,

    How do I add Efficiency to a server, so that it runs with set Eff, in capacity type I have work schedule and I do not want to use failure equations.



  5. Hi All,

    I have a server and I have to write out in a csv whenever the resource state of the server changes like from processing to blocked  or from blocked to processing and so on, I do not have a RPS version. any suggestions to this will be really helpful. Thanks

      Hi Chandak, 
      from definitions tab add a monitor element (i.e., monitor1) in your model and set its state variable name property to i.e., Server1.ResourceState. Also, from definitions tab include an excelconnect element which is a user defined element. set its excel workbook property as i.e., resource_state.xlsx (create a resource_state.xlsx file in the same folder where your .spfx file will run). In processes tab create a new process i.e., Process 1 and in there place an assign step and an excel write step (from user defined steps). Define a state variable i.e., row_index. in assign step set state variable name property as row_index and set new value property as row_index+1. In excel write step set excelconnect property as ExcelConnect1, set worksheet as "sheet 1" (resource_state.xlsx excel file's sheet name), set row as row_index, leave starting column property as default, and add two items such as "ResourceState" and "Run.TimeNow". at last, select process1 and set triggering event name as Monitor1.Event. 
      also, in order to get different resource states in your excel file you can define a work schedule or a failure mechanism on your server object. Hope it works?

      Dear Gocken,

      Thank you so much for your response. That is really helpful. Appreciate it.



  6. Hi All,

    I have defined the input buffer capacity and output buffer capacity for my servers, If the input buffer of destination server is full the vehicle still picks the entity(from output buffer of previous server) and moves to the destination(next) server and just waits with the entity unless input buffer capacity is available , how can I restrict the forklift from not picking up the entity or should only pick when the next server/destination has input buffer capacity available. any thoughts on this would be helpful.

  7. Hi All,

    In my Model I have a input table and while trouble shooting if I have to pick a particular order as in the below screen shot, it takes a while to search the same( I have approx. 2000 rows). Are their any efficient methods to search a particular row in table if not can this be added as a feature in Simio's next update? Right now its a drop down and then the order needs to be searched.

    Thank you.




  8. Hi All,

    Are their any tricks available to run experiments at a faster rate. currently I run 9 scenarios with 30 replications and it takes hours to Run.

    Any suggestion would be helpful.




  9. Hi All,

    I am Unmesh Chandak, working with Hirschvogel Incorporated- we are a forging industry based in Columbus Ohio, USA.We have been using SIMIO since 5 months.

    It has been an interesting journey with SIMIO modelling. I was thinking if anybody is interested to share knowledge/learnings/projects ,wherein we can share and learn from each other.

    We can show each other what we are working on, what are our challenges and grow together.

    Let me know if anybody is interested, and we can co-ordinate further. Thank you.

  10. Hi All,

    I am repeatedly getting this (attached picture) error in my Simio Model, what could be the probable cause and what should I make sure so that this problem does not repeat?

    I have added transfer, end transfer step in my process logic.

    I also have made sure I have enough storage capacity and also enough vehicles to complete the transfer.

    any suggestions would be helpful.

    Thank you :)


  11. 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?

  12. Hi Lucas, Thank you so much, it worked. Regards, Unmesh
  13. 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.
