Hello. I would need to create a simulation where the first and the last entities created goes to a different server than other. To do that I have created a node with to exiting path where the rule is a decide and the rule is entity.id == 1 || 150. But when I start the simulation the first entity created has the id = 18. How can I put that the first entity created as the .1 ?? Thank you

I would like to refer to the BicycleAssembly Simio Simbit as I'm using it as a reference to set up my own model. As I set the Initialization step of my model, I read the Orders table row by row, using a global variable called CurrentRowNumber. However, when an order entity is created, I would like to keep track of the row in the Orders table that entity is created from with a model-entity level state variable. However, I'm not sure how to do. I cannot just assign the value of this ModelEntity.State = GlobalCurrentRowNumber as the GlobalCurrentRowNumber continuously changes as the simulation runs. May I have some suggestion as to how to do so? Thank you

I have a situation where I have entities at a single source that are transferred to their destination by a vehicle. Each vehicle delivers 1 entity per trip. The destination is dictated by the entity's state variable ModelEntity.DropOff (if=1, then drop off at server 1, if=2, drop off at server 2, etc..). The vehicle path is the same for all vehicles (pick-up, then server 1, then server 2, etc.... return home) until they drop off their entity. Once they drop off their entity, they immediately return home to pick up another entity. With support's help, I have the model working fine except for the drop-off part (right now vehicles pick-up an entity, follow a nodelist, and dropoff entities at random destinations in the nodelist, and return home to pick up another) . I cannot figure out how to tell a vehicle to drop off a particular entity at a particular destination based on the attributes of the riding entity. Any help would be appreciated. Thanks, Scott

Heya, At the moment, I got a model in which trucks are following each other, and able to catch-up...till they reach a certain distance between each other. When they reach the desired distance I managed to set the same speed by using the following assign step: ModelEntity.Movement.Rate, new value: ModelEntity.NextEntityAheadOnLink.Movement.Rate. But whenever the entity ahead leaves the links, I obvioulsy get an error. So I would like to know how I let this entity check if there's any Entity ahead? Thanks in advance :).

Hi, I'm modeling an automated warehouse and I would like to know how can I only release an ítem to be processed if a release state (that the entity has) is set to true. Otherwise I want that entity to stay in queue until the release state is set to true (so it should be evaluating that condition all the time in order to know when it changes. Thank you in advance

I'm pretty sure my whole approach is flawed, but I don't see how else to do this. The attached is a very simplified version of what I'm trying to do. In the real problem, I have empty containers that enter a detached queue based on when they are retrieved from customers. I also have workers that need to select (through a fairly complicated process) which of these containers to batch together to enter a filling station. This selection process is complicated because it depends on filling material, pressure, volume, and safety stock of the sku (multiple skus can be combined in same batch provided filling material, pressure, and volume of container match). Anyway, what I'm aiming for is Create a batch When the worker is idle, he will go to a node and search among empty containers in the detached queue to assemble a complete batch. If there aren't enough containers, the worker will wait, idle. As empty containers arrive at the detached queue, they should trigger, somehow, the worker to try to create a batch again. There are new containers now, so maybe a batch is possible. (Preferably, since hundreds of containers could arrive at a time, this trigger would be for all the containers arriving at this specific time, not each container doing a separate trigger.) With the batch, the worker should move to a server, seize it and wait while the containers are filled. Then move to a separator to separate out the batch, moving the containers to full inventory and the worker should go back to try to create another batch. I'm stuck in a couple of places, specifically (so far) . . . I can't seem to get the worker, once batched, to move to the filling station. In fact, the Move block in PickingStation_Entered doesn't even fire. I can't figure out how to get the entity to trigger the worker to reevaluate the batching process. However I try this, the batching process is executed by either the entity's token or a model token. I can't see how to get the worker to be the executing token. Any help or guidance would be appreciated. Model.spfx

How do you use the transfer step to bring an entity from a path to another node. Currently at the reached end condition of the path I created a Transfer Step process that moves it to another node. I keep getting the error "The entity's current location '[EndOfLink] Path3' is invalid for attempting the specified transfer request". When I set From to EndOfLink I cannot fill any 'To' options. What do I do?

Hello, I am modeling a range wherein if a workstation encounters a failure while processing an entity, that entity needs to be destroyed and can't simply wait for the workstation to be repaired and then continue processing. The real world application models a failure of a critical piece of gear on boat, which would have to cancel the mission and return to port for repairs. In my case the mission (the entity) cannot wait for the repair, it must be canceled and start the whole process again later. I am really struggling to implement a process where the entity encountering the failure is destroyed when the failure occurs instead of just waiting around. Thanks for any help anyone can offer!

Hi, How can I change a state variable of a flow entity? For example, I want to change the color (i.e. picture state) of the entity based on the flow connector that the entity enters. Any suggestions how to do that (apart from converting the flow entity into a discrete entity and then back to a flow entity)? Especially, because flow connectors do not have Add-On processes. Any ideas are appreciated. I have already reviewed the SimBits for flow library and could not figure out. Thanks!

Hello I have a question about how to set up an Add-on process so that vehicle could drop off the entity based on the capacity of the conveyor, and if the capacity if full and the vehicle will be on idle.

I have one data table to create Order entities(based on SimBit - Entity by data table). Each order has properties such as type of Part and number of Parts. Each Order entity needs to reference a Part data table (based on SimBit - Leveled Arrivals) for that type of Part to create all the part entities for that order. Each Order type has an associated Part data table. I'm not sure how to establish the relationship between the order entity and the correct part data table. Any suggestions would be appreciated. Thank you.

Hi, What is the best way to access entities in a queue and select entities of a certain type to be processed first? I want to do this dynamically as the model is running. Thanks!

Dear All, New to Simio and struggling with the following problem. I would like to model an entity to exit a server at its assigned time as a state variable for now, I know this: Every entity is assigned before exiting the source with a state variable (pick-up time): TimeNow + random value between 1 -5 I want to use this state variable to decide with an add-on process if the server can finish processing; TimeNow == pick-up time if not, the server keeps processing. In other words, the processing time of the server depends on the state variable of each individual entity. Hope someone has tips or tricks to solve this!

Hi Team, Good morning, I have a question that I need support. On my simulation under Planning tab then Entity workflow I see the Orders that I created, but also some other items that I don't know where those came from. that is using resources. for example, I highlight on the picture attached on red color. OrderWIP01 is waiting for the grinder [1] on the finish1_1, when I looked for it, I saw that is on Phx4.89. What is that Phx4.89? Phx4 is one of the names of the entities. but why does appear as entity and not as a Order? At the moment I looking for why to increase the output, as the simulation is giving me 17 unit per shift, but engineering said that it should be around 20. I want to make sure the simulation is done correctly. Thanks in advance. Regards, Htatton Arm-boom-draft-R1-test-092718-Test-Scheduled-3tacking.spfx

Hi all, I've got a vehicle on a fixed route that has a capacity greater than one. Each entity has a loading and unloading time of 15 seconds. Now I want to let the vehicle dwell for 20 seconds at a node, but only if it has at least one pick-up or drop-off. When there is no pick-up or drop-off, there is no dwell time. So, if the vehicle loads or unloads only one entity it takes 20 seconds. But loading/unloading multiple entities at one node takes the loading/unloading time required. For a pick-up I can dwell only if the RidePickUpQueue of the current node is > 0. For a drop-off I'm however clueless what to put in the "dwell only if" How to implement this logic? Thanks!

I'm new to Simio. I'm trying to split my original entity into two different parts. The goal is to have the entity be separated, with half of them having a different server processing times through the same server.

Hello, I'm trying to model a paint flow line where I have two servers in one line(series and not parallel). If one entity gets painted in server 1, then I want that entity to just pass server two without getting processed. If the entity does not gets painted in server one than it can get processed in Server 2. I'm not sure how I should put this logic in Simio. Any help would be appreciated, thank you.

Hello SIMIO forum I'm new to SIMIO and I am working on a project for a industrial company creating masts for street lights So far I have setup the production as showed in the photo but i have one problem. Carl-C-layout.spfx

So with the combined help from the simio facebook chat, this forum I made the functions I requsted help for in my simulation model of a pharmacy queue work as intended. Now the final feature I need is to make a status label that keeps track of the amount of unique entities that has exceeded 10 minutes of waiting time before being processed at the cashier. I tried for about 2 hours to make it work but I am completely stuck atm and it is the last thing I need before I can start conducting experiments and begin the writing process. I hope someone will help! uploaded the current version of my model Pharmacy Model v6.9.spfx

Hello, I have a data table with 900 total entities, comprised of 10 different types of entities. I am trying to randomize which entities go through the model, but I need all 900 to go through. I've tried the "entity mix" technique, but it always overloads my model with too many entities. Does anyone have an idea of how to go about this? I want to run a series of experiments with a random selection of entities for each replication. I hope this makes sense. Thanks in advance! -Mario

Hello, I'm trying to route a certain percentage of one type of entity to a difference sequence. The SIMBIT "ChooseAlternateSequence" is great, but how do I change that for a specific entity? I tried to modify that SIMBIT with an additional part. I have Part A and Part B now, and in the process logic I used Decision --> ModelEntity.Is.PartB --> then to another Decision Block with the probability and sequencing. I just want "PartB" to have a probability of X to go through the "Adjust" server. When I run this, the logic doesn't recognize "ModelEntity.Is". Am I doing this completely wrong? Is there a way to do this without sequencing tables? I hope this makes sense. Thanks in advance! -Mario Without using a sequence table ChoosingAlternateSequencewithSpecificEntity.spfx

Hi Simio, Is it possible to model a block of raw material being turned into a part and swarf? I.e. a single part entity being split into two different part entities? Thanks Kevin

Hello, I am modeling a container terminal. I have different servers which model my container storage yard. I have two different Model Entities, "ImportContainers" and "ExportContainers". I created an Add-On Process on Entering the OutputNode of the storage servers. In this process, the destination node is defined ("SetNode"-step) based on the type of Entity and a transporter ride is initiated ("Ride"-step). It works. Now I want to change the destination to a group of servers (which represent a group of truck loading stations). So I grouped the InputNodes of these servers into a NodeList. But in the Add-On Process I can't set the NodeList as a Destination in the "SetNode"-Step. I need this, because I want to set different NodeList's as a destination for my "ImportContainers" and "ExportContainers" respectively. My questions are: 1. How can I set a NodeList as a destination in an Add-On Process? 2. When using NodeList's as destination, how can I be sure that only servers are choosen randomly from that list which are not full? Thanks!

Hi, currently my model has 2 manufacturing lines that are mirror to each other, depending on constraints by diameter, parts will go to a specific line. If parts are <60 inches they would go through line 1, but if parts are greater or less they can also go through line 2. My problem is I want to have Multiple Sequences on a entity and then be filter by diameter and line capacity. Any ideas?

Hello, I'm very new to SIMIO and apologize if this question is too elementary. I've been trying to figure out how to run the simulation from a defined list of entities. Most of the SIMBITS and examples I have seen use a random "product mix" or other means to produce entities. Is there a way to simply run say, 40 defined mixed entities from the data table. I'd like to run several different entities from the data table, all with different sequences and processing times. Similar to the SIMBIT EntityFollowsSequenceWithTable but with a defined amount of PartA,PartB,and PartC entities. Thank you for the help!
