Hi, I would like to return information from an entity in a queue (parent input buffer) at a specific index. If I use the search step with following property values (see attached image) I receive an error (see attached image). What does this error exactly mean and how can I solve this problem? Thanks in advance! Christa

Hi, Is it possible to set the state variable of the parent entity in a batch equal to the sum of state variables of all member entities in the batch? Context of the case; a truck (parent) is loaded with x number of orders (members). These orders have a specific value for the state variable 'NumberOfRollContainers'. The truck has the state variable 'TotalRollContainers', which should equal the sum of the 'NumberOfRollContainers' in that batch. Kind regards, Christa -
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 -
Hello! I posted a question while building a human-accessible elevator using SIMIO. The modelentity couldn't build its own system to get off the elevator, so I made the appearance of the elevator using a worker. At this time, I want to make the elevator stop from the low floor to the high floor, but the elevator is stopping randomly. For example, the elevator should stop in the order of the first, second, and third floors, but it stops randomly, such as the third, second, and first floors. I want to know the solution accordingly! I will attach the file for your understanding. Lift Project.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?

According to the reference guide, I can attach a status label to a model entity by first choosing the model entity and the creating the status label. It works for me, but not all the time. May I know if there is a way to fix this? My simio version is 10.174 Personal Edition. Thank you -
In my model, there are 2 types of entities created by 2 sources: Entity Type A and Entity Type B.The changeover setup time matrix is something like Previous Entity Type A TypeB Incoming Entity Type A 0 Random.exponential(15) Type B Random.Exponential(10) 0 I know how to do it using the changeover matrix, but apparently, the changeover matrix can't take random distributions. May I have some suggestions as to how to go about this? Thank you!

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! -
Hello, We want to assign the entities to different servers. The first server has FIFO selection system, and the second has FIFO with entity type OTC as the first priority, and the third server has FIFO. Furthermore, the servers open and close sometimes, but the entities keep transfering to the closed server. How can we divide them after the described rules? We have tried to get the output node to select from a list of nodes with the input of the different servers, but then the entities always choose server1. OTC-and-prescription-model.spfx -
does anyone has ideas about record the total time of the car loaded and empty travel time? help please Model -1.spfx -
I have entity1 and entity2 entering a server. I want entity1 to have priority over entity2 when in the input buffer waiting to be processed no matter how many entities are already in the input buffer. I'm using connectors leading the entities into the server input node. Any suggestions?

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. -
Hi, Lets say I wanted to create two simple Simio models, where an entity is made, processed by one server, and moved to the next model, in the following way: source1 > server1 > sink1 >> source2 > server2 > sink2 Where 1 is in model1 and 2 is in model2. I was wondering if it is possible to set things so that whenever an entity goes into sink1, a new entity is made in the second model (at the same time)? Is there a user-made add-on process step that does something close to this? If there is a simpler way than making a new process step, please let me know. Thank you
-
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 -
Hi, It is possible to add a tear-down time in a server? I have a server with a capacity over 1, so I would like to add a tear-down time to simulate the cleaning of a bed in a hospital after it was used. Thanks!

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! -
How to handle large number of active entities
Jscarbs replied to rubchone's topic in SI General Discussions
I am also interested in this idea of writing entity information to a file. -
Hello. I'm quite new to make process logic in Simio. I have 3 Servers(server1, server2, server3) and the entity travel from server1 to server2 and server3 in order by Vehicle1. The server2 and server3 do not have any buffer; zero input buffer and zero output buffer. So, I need a process which controls deadlock. I thought when the destination of Vehicle1 is Output@Server1, check whether server2 has an entity in processing buffer. If it has, again, check server3 has an entity in processing buffer. So, my conditions are below when the destination of Vehicle1 is Output@Server1. 1. If Server2 and Server3 have an entity in processing buffer, wait until Server3 has finished process, then transfer entity in server3 to Sink1 first and transfer entity in Server2 to Server3. 2. If Only Server2 has an entity, wait unitl Server2 has finished process, then transfer entity in Server2 to Server3 and transfer entity in Server1 to Server2. 3. If Only Server3 has an entity, do not wait any situation. I've built a process steps to implement it, but doesn't work.. I don't know my logic has problems or process step has problems... I've attached my model below. Could you solve or suggest about my problem? Thank you. Jay. RoutingProblem.spfx

is it possible to implement several timeline sequences for each model entity? For example, a patient goes through both a physical movement and a service movement, and they are not necessarily correlated. I have the timestamps for both movements. A patient could have a physical route of (start in bed1 @ 4pm -> move to bed 2 @ 5pm -> move to bed1 @ 6pm -> exit hospital @ 6:30pm) as well as a "service" route of (start in waiting mode @ 4pm -> nurse1 checks for 20 minutes @ 4:30pm -> nurse2 checks for 10 minutes @ 5:10pm -> doctor checks for 3 minutes @ 5:30pm -> exit hospital @ 6:30pm). I know how to implement the physical route by using sequence tables but what about incorporating the service route into the patient?

Good day everyone, I need to acess the average waiting time in a member input buffer of a combiner. First of all, how is there not an easy option to acess average time in queues? Most of the times I have to tally everything, which in turn doesnt work with experiments... It has been a real struggle. Anyways, I was using the approach of using an entyti state variable to record the time when it enters the member queue and another one to register when it leaves the given queue and then tally it. The problem is with combiners, the parent entity "wins" and so using ModelEntity.State Variable - reffering the one from the member - does not work. Any ideas? Thanks

I have a task sequence model using the Immediate Predecessor method. I would like to add in a rejection rate for each task, and then a unique processing time for the rework. Is this possible?
-
I have a problem with producing/consuming within my TaskSequence. I need multiple task operation (prepare -> work -> clean -> produce), where I'm also consuming/producing material defined inside my BOM table. When I'm trying to reference material requirements on the BOM table I get an error: "Could not determine the row to use in the referenced table or repeat group ...", references to the processing time and other parameters are working fine. If I set the task sequence reference to the BOM table, then material requirements works OK, but I could not add more than 1 task. I'm using version 15.241.27814 . Best regards, Žan

Hi! I try to modelize a production process. All my entities are of the type. But I want to give at each entity parameters such as height and length. I want that Simio generate it randomly in a state variable as an entity exit the source. My problem is the those parameters don't follow a standard distrubution as a normal ou triangular one. It follows time series (chronological series). Since it's a current pattern in production, I was wondering if there is a simple way to implement it in Simio? Thank you in advance! Pierre (I hope it's clear enough? Don't hesitate to ask me precisions if it isn't.) -
Hey all, My team is developing a model to simulate a network of electric fleet vehicles. We are hoping to track the number of cars parked at a charger in the model as a state variable (called NumCars), and then reference this value in the "processes" tab of the model entity, in order to assign individual cars certain values (called Signal). We have been unable to correctly reference NumCars in the Signal process within model entity. We attempted to use Model.NumCars to reference this value, but received an error stating: "Unable to get value of the property. Referenced definition type 'Model' does not match executing type 'ModelEntity'. Is there any way to reference a model state variable within a model entity process, as we are hoping to do? Thanks, Joe -
Hi. I´m having a very basic doubt about processing times. I have two products which one with a different processing time that varies from server to server, so when the model entity arrives at one specific server, i need to "read" what kind of product is passing and what´s the server in use from a table. I believe that´s an easy problem, but a can´t figure out how to do it. Thanks
