  1. 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
  2. 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
  3. 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
  4. 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.
  5. 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
  6. Hello, I'm working on a problem where at some point a worker will transport a specific amount of pallets. Whereafter these pallets are processed by a server and a server wil process them. Once processed, a different worker (or the same worker) will move the pallets to the next server. How do I save these entities as a batch and let workers know how much pallets they can process? At the moment I have two approaches. One where I create a 'batch' as an entity and assign to it the amount of pallets. The 'problem' in that case is that I do need to count the amount of pallets at a server, since it has a certain capacity. And sometimes an initial batch whitch comes from a truck needs to be split to fit the capacity of workers. But once this would be fixed, the worker will always transport the right amount of pallets. A second approach that I have tried is to create the pallet entities normally, and assign a 'PalletHistory' in the modelEntity properties, but I find that after processing I can't find this palletHistory for the workers to get a sign of how many pallets to transport. Do any of you guys have an idea how I can approach this? Greetings
  7. I wonder if it is possible to pick one particular entity from the BatchMembersQeue and unbatch it. For example I have a pallet with 10 entities batched (9 red and 1 blue) and I want to remove only the blue one. I was able to find the entity with a search step, but I cannot transfer it or unbach it. Any ideas? TnksUnbatch one entity.spfx
  8. Hello, I'm working on an emergency department (ED) model where I'm using both nurses and doctors as resources. At the ED, there is a 4:1 Patient to Nurse ratio, meaning that on average, a nurse takes care of 4 patients at the same time. When I was thinking about how to implement this logic on Simio, I looked at this option on the Seize step under Advanced options (you can see it on the picture I attached). I set the Units per Object to 0.25 - because I thought that every time a patient seizes a nurse, it will take out 0.25 out of 1 unit of capacity, instead of taking the whole 1, allowing for 3 other patients to seize her before she is completely busy. However, this doesn't work, because I ran a model trace as I ran the model and the server is ignoring the seize because the "Units per object" is set to 0 (which is not, it's set to 0.25) - the exact model trace comment is: "Ignoring resource release of type Specific 'Nurse'. The required capacity units per object '0' is not a positive quantity.". Therefore, the model ignores the resource seize and processes the entity without the resource. Is this because this property field only works with integers? I thought of a work around by just multiplying my number of nurses by 4 to account for that, but that's not optimal. Would there be any other way of achieving this? Thank you very much for the help!
  9. The manufacturing line I am trying to simulate has two servers whose behavior I am having trouble modeling. First, these two servers are in parallel. Second, these servers process units in batches of 14. Third, I need both servers to not start a batch until at least 14 units are present in queue. Lastly, I need to pool the queue for both servers into a single queue. Any help would be appreciated. Thank you!
  10. Thank you for the model! It took a long time to get the sprint release but now I can see it and it helps. Now I have another problem. I am trying to do a pick up at two different places and the drop off at one destination. There I want to have the transport costs split on the entity with the calculation TransportCostRate/TransportQty. The logic works like this: The transport from Source1 to Source2 (or BasicNode4) should be charged and assigned to ModelEntity.Cost. Then from Source2 to Server1 another calculation should be done, now with the increased transport quantity in dependency. But in BasicNode4 the process is not triggered by the ModelEntity, but by the Transporter. Is there any way that the process is triggered by the passenger? (the entity in the ridestation). The model is in the appendix. Best regards. Model_421.spfx
  11. Thank you for the quick answer! Yes I know the ABC Costing Calculation in Simio, but I forgot to add, that I want to divide the total transport costs among the individual components that are transported at the same time. I think it would work with the calculation: TransportCostRate / TransportQty * TransportTime , so I just have to track the transport quantity for example with MyVehicle.RideStation.Contents. And my small model is just a example. My goal is to set up a cost analysis tool with calculation of transport costs, bufffer costs, processing costs, ... for finished production models. And for example the buffer costs, i want to use more specific cost rates (footprint dependence for example, ...) The disadvantage of my custom way is that so far I can determine the costs only at certain points (for example pick up and drop off) in time and not "continuously" as it is now with the automatic calculation. Or do you know if there is a way to adjust these "custom" times so that they are also calculated continuously?
  12. 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
  13. I've ran into the following problem with a combiner: I'm using it to model a load zone where taxis arrive to the parent node, passengers arrive to the member node, and the number of passengers boarding each vehicle is set by a random.discrete distribution (so that for instance 50% of the taxis have 1 passenger, 30% over 2, and 20% have three). This all works great. But now, instead of having my passengers queue at the input node, I was hoping to make them queue at another upstream node, connected to the member input node by a path and every time a taxi arrives, I would like to send to the combiner only the number of passengers that will be batched with the taxi. I tried using Combiner.BatchQuantity but without success so far. From what I've seen by looking at a display showing Combiner.BatchQuantify, it seems it's continuously going through its possibilities, whether a taxi is at the parent input node or not. Then I thought that maybe the number picked to batch passengers with taxis, was selected from that continuously changing value when a taxi entered the parent node, so I tried using the event ParentInput@Combiner1.Exited (as well as ParentInput@Combiner1.Entered) to extract the batchquantify assigned to that taxi but the value did not match the actual batching. So I guess my question is: is there a way to access the value that is picked by the batching process to use it to send the right number of members to the combiner? Thank you very much for your help.

  14. 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!
  15. Hi, We have a model where we have multiple entity states. This creates interface challenges in defining and populating these states or changing many of them at a time. My question is, can the UI be bypassed in some way using some kind of batch operations? For example suppose I want to assign 150 entity states using string construction and naming conventions easily set up in a spreadsheet. Is there a way to define all those states and import them from a file rather than hand editing each one in the Definitions UI? Another example is I want to set large numbers of these states at appropriate points in processing. Is there any way to do so by just importing name value pairs from a file rather than hand editing each one and copy pasting from a spreadsheet built up accordingly. Thanks Very Much, Jim
  16. You could also use the Release Batch Early Triggers to recheck the condition after an event.
  17. 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
  18. New to Simio and learning as I go. The attached model includes a CombinerNode1 that batches entities in groups of 2 & 5 (random.discrete). I would like Server1 to use different processing times for the different batch sizes. For example, a batch of 2 entities should be processed in 5 seconds; Batches of 5 entities in 7 seconds, etc.. Eventually I will create batches of up to 6 entities. I have tried using Server1.Processing.Contents for Processing Time, but seems to return the value of 1 all times. Any help is appreciated! Thanks! Processing time based on BatchSize.spfx
  19. In the batch that was created, I want to search the member entity with the lowest value for state variable "NumberOfRollContainers" and change its value to: <<TotalREQ" - 0.9 * "CapacityTrip">>, where "TotalREQ" and "CapacityTrip" are state variables of the parent entity. I am struggling with how to use the search step in this situation, so help is appreciated. Thanks in advance!
  20. So I have tried doing this, but i can't quite get the workers to pick up the right trolleys. The capacity of the worker is too big and it will pick up more than the batch sometimes. In the logic i tried to use 'search', but can't quite seem to find the right expression. Any ideas?
  21. I want to assign a state variable to the batch members of a parent entity, is this possible? the reason for this: I have 2 types of entities (passengers and bags), they separate, then go through different processes and then are combined again. but since the passenger entities have to be combined with "their own" bags, a state (or something else) should be assigned which can be referenced as "match expression" in the combiner. is this the right way of modeling this type of process? or should i do this another way?
  22. Hi all, I met some questions in building the model. It seems a very general quesiton but I didn't find any solution from internet... I'm building a general workflow model. I want to decide the quantity of a server to optimize the workflow. I want to use experiments or optquest to get the 'best' number for each server. If I set the capacity type as Fixed, then I can set the initial capacity as ''referenced property'', then I can use this as control in experiments/optquest. However, I have a work schedule for each server now which means I couldn't set the capacity type as Fixed. And then I couldn't set capacity as ''referenced property''. I don't know how to control this capacity in my experiments/optquest. I know I can change the 'value'(which means the capacity) in workschedule table. But I can not change this number flexible in experiments... Or I don't know how to set this value as ''referenced property'' . Is there anyone who could help me with this? Thanks a lot!
  23. In my model, I have a combiner that batch 1 parent entity and 9 member entities together. I then need these 10 entities, when travelling out of the output node of the combiner, to go to 2 different paths. 5 of them should go on a path to node A and 5 of them should go to another path to node B. I tried using Combiner.BatchQuantity at Output_Combiner_Entered Add-on process but it doesn't work. May I have some suggestions? Note that the batch number is not fixed and will vary during the simulation run.
  24. In my model, there is a combiner that generates a batch of 30 entities. After the combiner, I want to assign exactly 30% of the bach population (i.e: 9 members in a 30-member batch) to state "A" and the remaining 70% of the batch population (i.e: 21 members in a 30-member batch) to state "B". May I have some suggestions as to how to do so? Note that the number of members in a batch is varying for different batches Thank you!
