  1. Hi, I like to count total number of entities types waiting in front of the servers.Say for example, i am having entity1,entity2,entity3.Each entity is produced from separate sources(source1,source2,source3 respectively) .I got 5 servers(S1,S2,S3,S4,S5). Entity 1 processed in S1-S3-S5 Entity 2 processed in S1-S2-S4 Entity 3 processed in S3-S4-S5 Each entity has different arrival rate. i like to create a expression to sum the total number of entity type 1 waiting in queue infront of the servers S1-S3-S5.if total number of entity type 1 waiting is greater than 100 numbers,the next coming entity type 1 from the source1 should leave the whole system( i mean sink without processing)similarly i like to count for entity2,entity3. Can anyone help me out? Thanks, R
  2. Hello everyone, In My Model i attached, i have 4 diffrent type of entities. The model is a standart Source-Workstation-Sink model. In my model, entities come to Workstation2 and afterwards they are processing. In workstation2, if entity type is same, there is no setup time but if entity types are diffrent, there is 2 minute setup time. My question, which is very crucial for me at that time is, after all entities came to Workstation2, is there any way to set a variable how many entity type (as we can see in model, the number is 4) came to Workstation2.Inputbuffer.Contents? Or is there any way to see the number of them in a status label after they come to Workstation2.Inputbuffer.Contents? At that point, you may say that why are you using Tables instead of using ModelEntity for each type of entity. I know that i can do it in that way but if i can built the model at the end, i will have a lot of input. Thats why i preferred using Tables. I don't know if it is a simple question or not. However it makes me crazy because unfortunately i cannot find a way, i'm stuck on it. If anyone have an idea or know solution, please help me. Regards, Alper MyModel.spfx
  3. I want to have a source that creates one entity of each part type everyday. The total number of different parts in the system can vary and the user must define a priori. That is, you can have 1 to N different types. Then I want a server that will use the info from a table that contain the process time info for each 1 to N types and the server will use this table to process the entity based on their corresponding process times. I want to do this by placing only one one entity type, one source, and one server. The table will be populated with as many rows (N) as needed a priori. Thanks
  4. Hi, I'm currently building a model which involves a very large queue of entities to be read into the model and dynamically searched. I've attempted to limit the number in the model through different techniques such as reading in only relevant entities in at one time (from csv), Limiting the search ranges to distinct queues (as opposed to searching entire entity populations) and offsetting the reading and searching intervals (so they don't fall within the same time-stamps and slow the model). Despite this the model still runs rather slowly and (depending on variability) may still breach the 20,000 entities in system mark. I'm curious to find out how anyone else has handled large numbers of entities in the past? Is there a way to disable this 20k entities in system warning? Are there more efficient ways of generating and searching entities? Any feedback would be great. Michael
  5. In the model I attached, I would like entity1 to move based on a sequence, as I assigned it, but entity2 to to go in at transfer node1, and as it reaches the crossroads, go to alternative paths, path8-9-10, with 5% probability each. As far as I know this is not doable since they are different different routing logics, one is based on a sequence, and the other is on a probabilistic manner. Am I wrong? Entity based routing logic.spfx
  6. Hello guys! In the model I'm developing I have a means of transport (lets call it car) that is an entity, another entity that is a driver and a third type of entity that represents the products. The main purpose of the car is to take the driver to a destiny (to get to those destinies he needs to choose between many paths -> selection weight) and then the driver leaves the car, goes into an object I created (channel) takes the products he wants and returns them to the car. Then, if in the same place he is, he wants more products from channels above the one he is on (yy axis), he repeats the process until he is finished. After that he returns to the car and drives to the next set of channels in his "shop list". Until now, I'm modeling this as a batch of a batch (products wanted batched on the driver and driver batched on the car) but I need the products to go to the car whenever the driver returns from a set of channels (so that they don't walk always with the driver) So, I would like to know if anyone has any suggestions as how to do this. I though of something similar to Simbit "UsingAStorageQueue" but instead of using the batch step I wanted to add the products to a queue of the object that represents the car. I tried to create a Station in the car object and I put the driver there through the Transfer step but i can't remove it from that station So, can somebody please give me some advice on what would be the best approach to model this problem? Or, if you think I'm proceeding correctly, can you please tell me what I need to do to remove the driver from the station of the car? Thanks
  7. Hello. In my model, I have three timers that launch events at the same time: based on time, one (call it A) launch its event at 60, the second at 30 (B) and last at 120 ©. So every 120hours, the three launch their events. Does Simio choose randomly their order on the heap, or is there some kind of "hidden choice"? In "Simio event calendar", it is written that "Within an event type the events are ordered by event index; i.e. the order in which they were scheduled". I do not really understand "the schedule order". In my model, it seems that Simio chooses C-A-B for what I have seen. Is anyone able to explain? I thought that maybe, at time 0, C is put in "future events", so are B at 30 and A at 60. Then, at 60, A is added at 120 (after C so) and B at 90. Finally, B at 120 and we have the order C-A-B. Am I right? Thank you!
  8. This model is for a simulation of waste haulage. The model has two types of trucks. One big and one small running to different speeds through the same path. Because of the size of the trucks (capacity), the big truck is going to have more delay time in the resource compared to the small one. This is cyclical process where the truck is loaded, then the truck transport the load and last the truck unload and return to the resource to be loaded again. In the model I am assuming that the entities are the loads. The entity requests any truck available coming after release the load. Then, any truck (big or small) take the load to the unloading area. Now, the time this entity is going to use the resource (loader) depends on the type of the truck, so this entity is going to take more time in the resource area in a big truck. how could I make this simulation in Simio? is it possible to have resources with different time depending on the entity? I was using other software with no success so far.
  9. hello, is there any number in the simulation results which returns the average waiting time for each entity? If not how can I implement this situation easily? Thanks! Regards, Nadine
  10. Hello Simions i'm trying to simulate an ICU room. attached is my small intensive care unit. it consists of: 3 rooms (each room has 2 servers, which are a bed and couch) 1 waiting room (the waiting room has 1 server, which is a chair) 1 reception desk (desk has one server, which is a computer) on the left side of the model enters the visitors (model entity). on the right side of the model enters the patients on stretchers (model entity) my question is: how do i assign the visitor entity to go to a room that has a patient? i want the visitor to go to the couch/bed server in the room once a patient is placed in the bed. Currently, my problem is that the visitor will just randomly go into any room which sometimes doesn't even have a patient. So, i just need to know how do i assign a visitor to the couch once a patient is placed in the bed. Do i need to make some sort of table or state assignment? any help is greatly appreciated, thanks a bunch! sample project runs.spfx
  11. Hi everyone, i'm working on a model similar to the emergency room sample provided by simio. my question is: they show a patient (entity) walking to the bed (server) and when it gets to the bed the entity (patient) changes from walking to lying down on the bed. How is that done? i'm looking around and can't figure out what setting i need to change to make this happen on my model. i have simio version 5.91.10320 (32 bit). any help would be GREATLY appreciated. thanks a bunch!
  12. Hey guys, first of all, thanks for the contribution on these forums, I have learned a lot from the SimBit solutions along with forum threads. Herewith my first post/question: Based on the Vehicle Fixed Route SimBit, I've set up the following model: There are specific pickup/drop-off locations in each of the vehicles' fixed routes. Entities entering at the various Sources will each be allocated a destination location Sinks randomly (ie. at Source_1 Output Node the destination is randomly selected from a DestinationList, which contains all destination nodes). Enities in the right-side loop are only picked up by Vehicle 1, and entities in the left-hand loop are picked up by Vehicle 2. Sequence Allocated to Vehicle 1: Output@Source_1 -- Input@Sink_1 -- Input@Sink_3 -- Input@Sink_5 -- TransferNode1 Sequence Allocated to Vehicle 2: Output@Source_2 -- Input@Sink_2 -- TransferNode1 -- Input@Sink_4 Of course some entities' destinations in the right-hand loop are set to destination sinks on the left-hand loop, i.e. Source 1 entity destination is set to Sink 4, and vv. In this case I would like Vehicle 1 to transfer this specific entity to Vehicle 2 via TransferNode1, after which Vehicle 2 can drop the entity off at Sink 4. There can even be sort of a "swap" of entities which need to go to destinations not in its original vehicle's route/sequence. I've tried setting up a process where Vehicle 1 stops at TransferNode1, checks if entities need to be transferred, and if so, waits for Vehicle 2 which then picks up the entity from TransferNode1. Actually I don't know where to start with this process, or if I'm even thinking in the correct direction? Any ideas? Thanks in advance
  13. Hello, could you please explain the difference between entity, model entity and the defaultEntity and give me examples where I have to use which reference in an expression? Thanks a lot! Regards Nadine
  14. Hey, I want to store informations for each entity in a data table or data sheet. The resulting table should contain a list of all entities and for example the corresponding throughput times. In the ideal case average an maximum values are also given in the table. Which posibilities are there in Simio? Regards Nadine
  15. Hi, in my workstation what is the easiest way of making the Bill Of Materials (BOMs) consumption vary according to the entity that is being processed? For example if I get entity A I'll consume the BOM "BOM_of_A": If it is B I'll would consume "BOM_of_B". Thanks!
  16. Hi! I have this: Configurations are like: Then I have the station's contents being displayed in the External definitions. I can count the new entities entering the station.contents, but they don't visually appear in the queue... What am I doing wrong? Thanks!
