  1. Hi, You won't need batch logics of the definition. Just the combiner is enough. I made a simplified version of your model. Producto1 requires 1 med and 1 big, while Producto 2 requires 1 small and 1 big. Pay attention to the process that I created at TransferNode1, you'll need to adjust it for the Producto3 and 4. Watch the Combiner Object aswell. Hope it helps. ExampleSimplified.spfx
  2. Hello Vinicius, thank you for you help but I still having problems with the model. I can understand the logic behind of the SimBit "CombineMultipleEntityTypeOntoPallets" but I have some doubts. I change the model adding a combiner, I creted a intergrer model entity state to identify the quantity of containers, and I have a real state to identify the container but I dont know how change the batch logic of the container to each product. In the definitios tab you can see the batch logics. I hope you can help me Best regards. OptimoContenedores3.spfx
  3. Hello, I wouldn't use process for this one. There is a simple approach that you can use by modifying the SimBit "CombineMultipleEntityTypeOntoPallets". You'll need 3 ModelEntity Integer States to identify the quantity required of each Bin according to the Product. Let's say ModelEntity.Big, ModelEntity.Small and ModelEntity.Med. You can modify "Ops_Exited" step to assign those quantities. For the Producto1 for example, you'll have ModelEntity.Big == 1, ModelEntity.Med == 1 and ModelEntity.Small == 0. A little tip: you can use "Is.Producto1" (or "Is.Producto2", etc) on a decide step to identify which Producto is it. Now on the Combiner Object, follow the Simbit and change the BatchQuantity, to ModelEntity.Big, ModelEntity.Med and ModelEntity.Small. This should work.
  4. Hello everybody, I'm trying to make this work but I cant Type/Conteiner BinBig BinMed BinSmall Product1 1 1 - Product2 - 1 1 Product3 1 - 1 Product4 1 1 1 I want to make a node where these entities (Products and Bins) are convined in one batch, I try to use a process based in decitions and search.. the file is attached if you wanna take a look on it.. (the product have to be the parent) OptimoContenedores2.spfx
  5. Hi Fabian, I see two (or more) possible alternatives for solving this. Assuming that the box only receives one type of entity you can: 1. Create a state variable (for example st_CurrentBoxType) and every time an entity enters the combiner you assign the entity type to this state variable. This way, one the box is completed and exits the combiner you will be able to assign it the st_CurrentBoxType. 2. The other way is to execute a search step once the box is full. You can use "ModelEntity.BatchMembers.FirstItem" as match condition to locate the first batched entity, then in the found branch use an assing step to assign the ProdType from the found entity I'm sure there are a lot of ways of doing that... hope this helps saludos
  6. Hello everyone: I am modeling a packaging system by means of a combiner. 12 equal members are grouped in a box (parent). Before leaving the respective source, members are assigned a value (0, 1, 2) as a state variable (ESV_P) to distinguish them by product type. I want the box to have the value of the products state variable. For example, if the box contains 12 type 1 products, the box should be assigned with a state variable ESV_B equal to 1. Any suggestions? Best regards.
  7. Hi , I have a system with a combiner, that combines different variations of batches. On exiting the combiner the crane picks the combined entity up and drops up at a server. Each of the different batches will have a different load and unload time. Is there a way to do this? Basically, does batch contain product ‘A’ if so crane time is ‘X Mins’ Does batch contain product ‘B’ if so crane time is ‘Y Mins’ Thanks for any help!
  8. I used to have a similar problem. My advice, avoid the pallet entering the combiner untill you have defined de @new@ batch size, elseway the batchsize wont be updated. In my case I put a scan step in a prevoious node, retaining the pallet ouside the combiner until I've re-defined the batchsize. Let me know if that works Rds
  9. Got issues with a combiner. i have a server that processes the member parts but has a 0.1 probability of going to scrap, this means the batch size has changed. the parent part has a integer state that gets updated when this happens but doesn't update the combiner batch quantity property. I have attached an image showing this issue. you can see the pallet number displayed which is the way i match the parts with the correct pallet. the pallet(parent) also displays the batch size using the same integer state which i use in the combiner logic. Theres a pallet with 4 items on it and it shows the batch is 4 so why wont that process it? Also attached the whole model so you can look at it all Batch and Scrap.spfx
  10. Hi, A combiner is able to combine 1 or more entities into a parent entity. The number of entities that are batched together is specified in the property Batch Quantity. I recommend looking at the SimBit "Combine Multiple Entity Types Onto Pallets" for an example. Best, Khaled
  11. Hello, please I need your help. I have a combiner in my model called Revisar_pedido, which fulfills its function without any problem until, at one point, an entity enters (Pedido_PU.597) and gets stuck inside it and I can't understand why it doesn't come out. I already checked the functions, processes and states and nothing seems wrong. I attach my model for better understanding. Beforehand thank you very much. 06.11.spfx
  12. Is it fair to say that the longest waiting time in the parent queue is the first entity at the queue? If so, you could use something like: Candidate.Node.AssociatedObject.Combiner.ParentInputBuffer.Contents.TimeWaiting(Candidate.Node.AssociatedObject.Combiner.ParentInputBuffer.Contents.FirstItem) to access the combiner which has the largest value of the time waiting of the firstItem in the queue. It seems to work
  13. Hey, I've got a quick question on how to route to a combiner with the longest waiting time in their parent queue. I think it should be quite easy, but i cant seem to make it work. What i have been doing is setting the selection goal of my routing node to largest value, and select from a list. This largest value I think should be the the longest waiting time in the contents of the parentinput queue. I have tried this multiple ways both using assosiated object and without. When i recall the number waiting it seems to work, but with recalling the waiting time i'm doing something wrong. My current expression is: Candidate.Node.AssociatedObject.Combiner.ParentInputBuffer.Contents.TimeWaiting(ModelEntity) or Candidate.Combiner.ParentInputBuffer.Contents.TimeWaiting( object ) both seem to work for content.numberwaiting. I think i am describing the ( object ) part wrong but cant find how i should write for the modelentity otherwise. I have tried to recall a specific entititype like so --> TimeWaiting(Truck) this also does not work. Does somebody know how i can acces the ParentInputBuffer.Contents.TimeWaiting? Greeting Piet
  14. You need to put the search, release and transfer steps into the Add-on Process Triggers "Parent Entered" of the Combiners. For example, for the "Juntar_secos" combiner, at the "Parent Entered" Addon process, you would search for Slots.Processing.Contents, matching "Candidate.ModelEntity.Id_Del_Pedido == ModelEntity.Id_del_pedido". After that you should use a release step, to release Server "Slots", and a transfer step to transfer what have been found to Output@Slots.
  15. Thank you very much for your suggestion! But the condition indicated in the Search step is not met, since entities with any state number leave the server, regardless of the entity's id in the combiner's parentinput. 18.10.spfx
  16. Well, first thing, you don't need your entities to be bouncing between the output and the input of your server like that. If you want to use it as sort of storage, set both the processing time and the capacity to infinity. After that, at the moment that the parent entity enters the combiner "Parent Entered" you could search the queue of your storage using a search step with something like "Server1.Processing.Contents", with the condition of "Candidate.ModelEntity.State == ModelEntity.State", release the server and transfer what have been found to the output. You need to take some care on some situations, like what if the parent entity arrives first at the combiner then the member at the storage? And some care with batching quantities aswell. But I think you can handle it.
  17. Hi! In my model I have entities called "Pedido" which have a state called "id_del_pedido" which is equal to the ID of the entity. These entities will enter a Separator that will create copies of the entity according to a probability distribution. Since the new entities are copies of the parent entity, they will have the same "id_del_pedido" status as the parent entity. Subsequently, the entities created will enter a Server that acts as a warehouse. This Server is linked to a Combiner, when the parent entity reaches the Combiner's parentinput I want only entities whose "id_del_pedido" is equal to the ID of the entity that reached the Combiner's parentinput to leave the server. This works perfectly in the first Server-Combiner set of my model, but, the Combiner's outputnode is attached to another Combiner and I want to repeat the same activity as in the first Combiner but I get an error that I don't know how to solve. I attach my model so that my problem is better understood. Thank you very much in advance! 18.10.spfx
  18. Hi! can you help me please? In my model I have a server that I want to function as storage, this server is linked to a combiner which will combine the member entities that leave the server with a parent entity that will arrive at it from another node. Each member entity has a state with a unique number linking it to a parent entity (there may be more than one member entity with the same state number). How can I extract from the server only the member entities whose state is equal to the state of the parent entity that arrives at the parentinput of the combiner? Thank you so much! 18.10.spfx
  19. Hello Everyone, please can someone help me with this situation? I want to use a Server as a storage place, entities coming out of it go into the MemberInput of a Combiner. I want the number of entities that leave the Server to depend on the state of the entity that will enter the ParentInput of the Combiner. How can I access the state of the parent entity that will enter the combiner from the Output Node of the Server? Thank you very much, Greetings! 14.10.spfx
  20. Hi, I have a production line with 2 sources. The arrival of entity A in source 1 triggers an arrival of entity B in source 2. Entity A and entity B then enter their respective servers for a processing time. Entity A is processed at table_openings between 10 and 15 minutes with probabilities whereas Entity B is processed at table_MF for 10 minutes. The process type is task sequence. Both Entity join at a combiner. Entity A is the parent and Entity B is the member. Afterwards, the combined entity continue along the production line. I have expected processing times for each task at each server. Before starting a task, a process starts where a state statistic registers the state processing time of the entity. I also put list state to verify the schedule utilization. I have verified visually and the state value for processing time is correct for every station while the simulation is running. What I have observed is that the state statistic average processing time for the servers before the combiner is the expected value, however, all the other stations are 10 minutes off. The simio output has the right processing times for all the stations after the combiner but not for the two stations before the combiner. Moreover, the list state average time busy value are ok for all the stations after the combiner but again the station before the combiner, it gives the total number of minutes it was busy. Also, if i do the average of the state log observation for each station in excel afterwards, I get all the correct processing times. I am guessing it has something to do with the combiner, but I am lost. How can the processing time for table_MF be 10,48 when the processing time is a fixed 10 minutes in the facility window? Why is the list State MF and OP different from all the other list states? Thank you for your help!
  21. Hi, I'm making a manufacturing line sumilations where 2 entities representing components enter combiner, where they are being proccessed to a new single entity. How I'm suppoused to terminate those 2 entities that are entering the combiner and generate one new that is leaving? Also, can you combine more that 2 entities in one combiner?
  22. hi taylor, before the paralel servers place a combiner object. On combiner object set the right logic for batching. Then again set a logic for sending the batched entities to the appropriate server. I feel you should set this sending logic on the links to the servers. Hope this helps!
  23. Just use combiner object. There is a very close simbit in simbit library, just check it out.
  24. People often miss the fact that a Combiner is basically just a Server with some extra combining logic. It sounds like that is exactly what you need here. Replace your Server with a Combiner, then immediately follow your Combiner with a Separator to restore the entities to their individual members.
  25. you could use a Combiner object to represent the assy station. and on the combiner's After Processing Add-on trigger , you create a processes like below..
