Is it possible to release a resource after a model entity departs the system? I am trying to model a case when an exam room in a hospital is cleaned after a patient leaves the system. The exam room should not be made available to other patients prior to cleaning. It seems the default is to release all associated resources when an entity departs the system. Thanks in advance!

Hello, I have a very large number of different products that must go through a workstation and each of them have different setup / processing / teardown times. My idea was to create a table and import the data from Excel containing the product name, ratio, and setup times etc. I got that part done, but now I'm stuck. It seems I would need to create en entity with the name of each product? There must be another way? Thanks in advance. Samuel

I would like to record the total distance traveled in free space for 70+ of the same entity, going to random sinks from many different sources. I have tried using the "totaldistancetraveled" function, but can only get it to work for a specific entity (for example "ModelEntity[1].TotalDistanceTraveled"). What is the best way to do this.

Hello Simio-Community, I want to simulate a vegetable garden with a source, with a maximum number of vegetables (maximum arrivals in Simio). People can take as much vegetables as they want in the garden until it is empty. Once one vegetable has been gathered it takes a few weeks to grow again. Do you have an idea of how I can handle this ? I'm quite new in Simio. Thank you in advance,

I have two models in a project, one which handles supply (results in trucks being routed to one of several sinks) and one which handles demand (various sources). I would like to connect the sink of my supply model to the source of the demand model. Can I transfer entities between models? Or do I need to manually copy and paste each object from one of my models into the other to allow for the transfer of entities? This may be very simple, sorry if I'm the annoying newbie! Joy

Dear all, I have this problem: When an transporter is empty, he first has to search if there is an entity somewhere waiting to be picked up with the state: "Scan2=true". I tried to model this with the following process: - First decide if the vehicle is empty? - Search if there is an entity with this state waiting in his own VisitRequestQueue (search in Vehicle.visitrequestqueue for the match condition Candidate.ModelEntity.Scan2 == True) - Search is if there is an entity waiting in the rest of the model (search in Global.VisitRequestQueue for the match condition Candidate.ModelEntity.Scan2 == True) - If he found them, he has to pick them up, otherwise he has to continue with his normal routine. But i get the following error: Could somebody help me out? I also included the model. Model(5.5.2016).spfx

I want to access a property of a next entity on a link. For example, in Simbit "Checking Next Entity Ahead On Link", I want a speed of the next entity behind the current entity on a link. I refer to the behind entity and try to access other properties e.g. "NextEntityBehindOnLink.DesiredSpeed". However, it does not work. How should i do to solve this problem?

Hi I want to change a state-variable of each entity of a specific type. I am trying to reach this goal by using a search-step in a Process. The process is executed correctly but the search-step is not doing anything. I have set the following values for the search-step: CollectionType: EntityPopulation Entity Type: Besucher Search Type: Forward Match Condition: True Limit: Infinity The goal is that each entity of Type Besucher should flow to the "Found"-Branch where I have created an assign-step for changing the state. But the Step following the "Found"-Branch is never reached and also the Step following the "Original"-Branch is never reached (I have set a breakpoint at thia steps.) I have also attached a screenshot. I hope, someone can help me.

Hi! I want to model the loading of containers at a terminal. On each terminal there is a queue with containers. Each container has different properties, like the size in TEU (is equal to 1 or 2) and their destination. I want to batch a vehicle (parent entity) to a group of containers (member entities). When the capacity of the vehicle is for instance 10 TEUs, you have to batch an amount of containers to that vehicle. The problem is that I cannot express the Batch Quantity in containers, but only in TEUs. Per container the size in TEUs is known and the containers (member entities) must all have the same destination. What should be the expression for the Batch Quantity? It is the most optimal when the vehicle with a capacity of 10 TEUs will be loaded fully. So, when the first number of containers in the list that will be loaded on the vehicle has a common size of 9 TEUs, the last spot can only be occupied by a 1 TEU container. When the first container waiting is 2 TEUs, this one must wait, but the first 1 TEU container waiting in the queue can be taken by the vehicle. How to model this? Does someone has an idea to model this problem? Thanks!

Is there a way to create a queue (buffer) that reorders its elements whenever a new element enters in it? We only have 4 available entry ranking rules. What if I want to implement a more complex rule, are there any solutions? Plus, what's the best way to create a queue? (I don't want it to be attached to a server or workstation. It may be a situation where a queue receives elements from multiple workstations and delivers to multiple workstations) Thank you for the attention

Hi I want to modelling the following problem: A source1 is creating Entities which are wander in free space. Another source2 is creating other Entities. This entities acts as firefighters and should be able to pick up other entities which are created from source1. When an entity of source1 has a value of a specified property below a minimal-value (the health) it should be picked up by a firefighter-entity which was created from source2. Can someone give me some hints, how I can modeling the firefighter-entity to pickup other entities? - Thank you for your help. Best Regards, Thomas

Hello, I have a server that can handle different entities (not simultaneously). I want a process to take place only when the server is processing a specific entity (for example: the entity A). Is there a step which discriminates the entity between all the others ? Or is there another way to do what I want ? Thanks

Hello, I am currently working on a SIMIO model simulating a maintenance workshop. The model is made of roughly a 1000 entities of various type, going through potentially different paths among 30 servers over the course of a year. I would like to be able to extract an excel file keeping the flow history of each entity, meaning at least the date, the server, and the ID of the entity and of the worker used, for each step of the simulation. I feel like this must be possible to achieve using Tally statistics, but even after reading some simbits solution, I can't figure out a way to do this. Thank you for your help, Clem

Alright - I am going to try to phrase a previous question differently and see if anyone can help because I am still having difficulty with this... In the attached, simplified version of what I am attempting, I have a Parent Entity created. And for every Parent Entity, Math.Round((Random.Uniform(1,4)) number of Member Entities are created. Please help me if possible, to set an expression for the Batch Size that waits for each of the created members and batches them. I have the logic for how they match, but I can't seem to get the Batch Quantity to change based on how many of the Members were created each time. Any help appreciated! BatchingLogic.spfx

Is there any way I can define a maximun waiting time in a queue? So, if the time waiting for an entity is bigger than the setted one, a message of error or collapse appears. Thanks!

Hello, In my model, all the entities ride on transporters. At a server, the entitie goes through the server and the transporter has to wait at the server until the entity is done, and then pick up the entity and bring the entity to the next location I tried to model this by selecting "Keep reserved if" true, but this is not possible for transporters with a capacity greater then one (the explanation from the simio help guide is included as an attachment). My transporters have a capacity of 5. Is there another way to model this? Thanks!

Hello, I want to bring a box in front of two server. I want the units in the box to be the entity for the two servers. How can I do that ???

Good night, It's my first post here, and I want to say at first very thanks for the help, I'm going to explain a little the issue: I'm making my own simulation about a supermarket, and I'm trying to generate a list of things which had to be assigned to a Entity. I generated a string property as vector with 4 rows (ArticuloQueCompra), and I sent from a table (Listadelacompra). I also had made the same with another property (CantidadArticulo). After, I sent the values throw a trigger (AsignacionManualDatos). I thought it isn't the best way for this but I didn't find the right. I appreciate the time you spend for help, so, thanks again. Regards,

Hello, Is it possible to change the state of just the entities while they are on a transporter? Because now i get an error when I put an add-on process to change the state of the entities going throug the node because simio tries to change the state of the transporter too. Thanks for the help, would really appreciate it!

Dear all, I would like to know how to model the following problem: At creation, each entity gets a destination node. But 5 % of the entities have to make a stop-over at a certain node called "security check". After going through "security Check" the entity has to go to the destination he gained at creation. How to model such a "stop-over"? Thanks!

Hello! I am modeling a wash station that takes 30 minutes for the first piece, and an additional 5 for each piece after that(so a batch of 3 would take 40 minutes, a batch of 6 would take 55 minutes, and so on) but I'm having some trouble putting this into a processing time. The added problem is that the number of entities changes. Currently I'm using a source that produces one "shipment" a day with "Entities per arrival" set as "random.triangular(3,13,19)" which is working fine for my quantity, but I don't know how to relate that into the processing time of the next workstation. Thanks!

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

Dear all, I have a question about modelling arrivals. Entities have to arrive in groups of 5. These 5 entities can be of different entity types. Now in my model, each time an entity "group" of 5 entities arrives, they are all from the same entity type. This is probably because first is decided which type the group will be, and then the 5 entities are created. Each time these 5 entities arrive, there is a Table Reference Assignment referring to the "productmix", from where is decided which entity types will be created. All the entities in the arrival have to be as the percentage in the producttable. So more types per arrival group can arrive. Does somebody know how to model this? Thanks. My model is included as an attachment. Entity_Arrival_Problem.spfx

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
