  1. Sometimes it helps to have entities inserted into more queues for quicker selection. Something like a card indexes in the libraty. That way you can shorten the search steps time.
  2. Do your parcels have their destinations (carts) or will they go to the nearest cart possible?
  3. Why are you uploading the texts in docx?
  4. Hi, Dave, I tried to create my own object composite, but if I use the entity reference with AutoCreate inside my LiftTruck, the Lifting device referenced cannot be moved in External View. Do you have any idea of how to solve this? Thanks
  5. We have developed an add-in with as many as 60 forecasting algorithms. Input is a table with time series data, output is a table with mean and uncertainity intervals. if you have any questions please contact me on tulach@logio.cz
  6. This is very usefull, (didn't test it, but I use simillar approach without using new object. It is a good idea to crate an object for this.
  7. You should try the simbits (in support Ribbon). Insert keyword (agent) and you will see many use cases with models and description
  8. YOu have the same capability in simio. Just create as many workstations you need and constrain them with resources. Resources are dynamicaly created in simio, so you can create a new if resource in a resource population if needed.
  9. Yes, I agree with Adam. For all things we do that require programming, we use GIT. I know that SIMIO uses TortoiseSVN for taking care of all the development of SIMIO. What I sometimes do is that I copy my model to do some minor or major changes (in the same project) and than if the changes are for the benefit of modelling I have to sometimes reincorporate to the Master model. I understand, that you need to have signed XML files, so that noone can write models in pure XML, but I would suggest adding some version control into SIMIO (maybe it will take a long time to implement, but will make a significant competing advantage). Abbility to branch model, make changes on a branch, test it and than incorporate some changes into main version will be a nice advantage and will open possibilities to use more team work in SIMIO. I think that something like version control can be implemented in SIMIO. Petr
  10. Hi David, it is nice that you encourage us to request such things. In my oppinion, ability to place objects in SIMIO by modification of xml file will be great. Although, I can use API and Excel-add on, it is slow if you have more objects. We made some modifications to the add-on Glen created, so that it is not switching between excel and simio after each row, but still for hundreds of object (even simple nodes) it takes a long time. And you want to utilize some automation when it comes to placing hundreds of objects. Or enabling SIMIO to do this add-on placing of objects quickly will solve the problem for us. I can send you the files and modified add-on if you are interested in testing.
  11. Hi, I am quite confused with the flow entities. When entity is converted into flow using ItemToFlow object these flowentities can be seen in watch window in a pipe. The volume of this flow entity seems to vary based on the cross-section of the first pipe after the IntemToFlow object. Why am I asking this question? I deal with a model, where volumes are in m3 and weights in tons, and soon the model will come up with more than 2500 entities (flow entities) because it chunks the flow into small discrete entities (ike .3 m3 per each). I would like to set this so that it is for instace 1m3 chunk. Is this possible? Petr
  12. Hi, I think there is a misunderstanding about the material. Material is an element and therefore cannot be transfered to a node. I believe that this is because it is a more lightweight than the entity. So if you have many materials it will not consume your memory (you have one material and SIMIO just holds information about its quantity). So you can't move one quantity of material. What you can do for visualisation purpose is to create an entity acting on behalf of one quantity of material (or more like a box full of bolts). And than move it. There is an implementation of using BOM table and Search step to find materials to consume.
  13. It depends on what you want to model. If the picked up entity is of no use after you can simply destroy it. Or you can create Firefighters as vehicles or workers Because vehicles and workers are based on entities.
  14. Cant open the model (please next time tell us that you use academic version). But from my experience this Error is caused by entity haven't end its transfer step. If you use transfer into station you must create proces mystation_entered triggered by mystation_entered_event and place EndTransfer step there. Otherwise entity hangs in WaitingFor transfer state. The other possibility is that another process is already dealing with this entity and is transfering it. This sometimes happen if you search queue or station for entities and try to transfer them. If you don't check carefully for entities already beeing transfered, you get this message.
  15. Hi Glen, I used the plugin to import some hundreds of objects and it was too slow and frequently made SIMIO unresponding. I used our programmers to change the logic of plugin (problem was frequent comunication between Excel and SIMIO, so they used an array or so instead) and we added small lag between inserting objects (something like math.epsilon in simio) to preven freezing. And a new progressbar, that will not leave the user in darkness about whats going on. Feel free to use it. ImportObjectsAndLinksFromSpreadsheetLOGIO.rar
  16. What about using Combiner object to combine them?
  17. You will probably have to start with specification of what is the funcionality and aim of the simulation. I can imagine, that different approaches will be used if you are concerned with storage capacity or if you want to simulate utilization of vehicles. Other differences apply if you want to have random (chaotic) storage or will have some specific demand for storing different types of pallets.
  18. http://www.simio.com/forums/viewtopic.php?f=10&t=1929&p=6233&hilit=change+sequence#p6233 Here it is discussed
  19. Hi Dave, although I understand this solution (and see that easy use of student licences is usefull in spreading SIMIO in schools) it sometimes prevent commercial users there in forum to help students with their problems. Maybe some use of specialized portal edition, where students can upload their models and others can take a look can be a solution.
  20. Happened to me between sprints 120 and 123 My support ticket: I had made some unwise things testing both sprint 123 an 120. In one time I swithed from 123 to 120 and then back to 123 and I found all decide steps with no Coditions. All conditions were set to 0.0. I know that I should not do this (go back and forth versions) and don't blame your development staff, but I think this behaviour would be interesting for them. I just felt back to previous version. I don't think there is another option.
  21. Right click on the table name and select new horizontal / vertical group.
  22. I also have developed a warehouse can you contact me on tulach@logio.cz i would like to discuss it.
  23. Each xml has a hash on its end, to verify it was created in SIMIO. This is because otherwise you will not need licecences. You can find other features like creating model from excel spreadsheet or via API.
  24. Try searching for sequence in this forum. It was discussed previously.
  25. path1.Contents.FirstItem I think this is what you want.
