Hello, I am writing my master thesis on production system design with simulation modeling. I have designed two models in Simio - one for current production system and one for optimized one. They are both designed in a correct way and they work as they are supposed to. The only difference between them is in path lengths. The difference between results from optimized and current system should be 3 - 5 % but for some reason I get all of the results identical to the last decimal place after running an experiment. I have attached a picture of my path properites and travel logic of entities. My guess is that for some reason path length is not being considered in the simulation. If anybody has any ideas what could be wrong, i would really appreciate your help.

Hi Everyone, is there a way to always show all the Path labels without click on them?

Hello, I'm college student preparing the contest sponsored by "KOREA SOCIETY FOR SIMULATION". So I'm making model which has no input buffer , just remaining on the path. But the issue is that, if i set the input buffer as 0, the source makes entities only two, which is the sum of the sever's capacity.... I have seen that kind of model at the jsmith.co , but my model doesn't act like that.. What should I do for my model? isThereInputBufferCapa.spfx -
I'm trying to model a towing company. A call comes either jump start or tow (entity 1 and 2) from two different sources. They go through a dispatch (server1) and get delivered to a specific driver (servers 2,3,4 or 5) . Each call coming in will have some exponentially distributed distance from origin associated with it (and direction component?) My challenges are: Is there a way to take and entity from a source and move it into free space some vector away from the source (distance and direction). Then, if that is possible, can I move a server to that location to process it (and if a tow then move some other vector distance after process). Finally, the ultimate goal of the model is to create a conditional routing logic for the dispatch server to compare distance from call and availability of drivers. Such that if a driver is finishing up near the next call, that server will take priority over the one with an empty queue if further away. TLDR: Can servers move? Is there a way I can change how long a path is based on variable input?

Hello, I want to model an evacuation network design problem with Simio. My goal is to consider traffic congestion in the model. Congestion happens when road capacity is not enough for that amount of people immediately leave the source node. I was wondering if you could let me know how to consider capacity for either path or connector. I would be happy if you could share an example with me. Thanks, Nadere

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?

Hi everyone, Im currently modeling a facility layout and it has plenty of paths between machines. is there a way to generate a path list with inputs and outputs, so it would be easier to keep track of their routes?

Hi, I implemented a model similiar to the SimBit 'Single Worker Completes Process And Moves To Node' but in my model the the worker can arrive first at Server2 than the entity (which represents that the work to be made in the entity is already finished), so it's not necessary to have a Worker in Server2 for it to work. By implementing a different release on the Worker I managed to move the Worker back to BasicNode1 before the entity has entered Server2, but it will move always with the same DesiredSpeed. I wanted to know if there is a way to move the Worker from BasicNode2 to BasicNode1 with a different velocity from the one defined to move the Woker from BasicNode1 to BasicNode2. I'm rookie, any help it's welcomed. Manel

Hi All, At the moment, I'm trying to model a warehouse. This warehouse consists of aisles: long sections of bi-directional paths, intermitted by basic nodes that represent picking locations. Workers walk through these aisles to pick orders. See also the attachment: the nodes are not visible but there are 20 nodes in every aisle. However, the bi-directional path does not enable workers to walk in two directions. It is possible for workers to encouter each other while traversing the aisle in opposite direction. This will create a blocking situation. I tried to solve it by using the 'Travel' step, such that the workers travel through 'free space' within a certain width around the warehouse network (setting 'avoind collision' to 'true). The problem however still exists. Is there a neat solution for this? It is a possibility to introduce all sort of extra bypass paths. However, this will make the model more complex and introduces walked distance biases. One of the purposes of this model is to compare theoretical picking times (based on walking straight through the aisle) with simulation. Adding extra bypass paths would violate therefore the purpose of the model. Thanks in advance for your suggestions! Wouter

Hi everyone! As the title sugests I want to know if there is some way to access the entities that are on a Path, similar to what we can do to access the elements on a queue. Thanks

Hi How can I define the selection weight of a path using a state variable? it is supposed to change throughout the run. Can I used a table to do that? if yes, how? Thanks

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?

Hi, I'm working on a model with multiple paths and I'm using time paths to move entities. I recently noticed that the "Shortest Path" Outbound Link Rule doesn't work with time paths since it looks at the size of the path (as in, the length of the drawn segment) instead of the time it takes to travel the path. Is there any way to have a transfer node choose the time path with the shortest travel time? Thanks.

Dear colleagues, we're starting to post a number of graphical symbols that can be useful for your models. Greetings, Note: We built them with SketchUp on purpose to be used within Simio. You're free to use them and share them with other Simio customers, but please don't divulgate them on Google Warehouse. Symbols4Simio.ZIP
