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 -
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!

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!

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!

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

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! -
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

Hi, I would like to model the following. Having information stored in every entity instance containing the information to a set of tasks that can be performed to that entity and, whether they have been performed. I have created a model. There is a set of entities that will enter the model. This is stores in a table (allEntities). Some tasks can be done to entities. This is in another table (allTasks). Every single entity will have several tasks associated among all possible tasks. This is in a third table (infoEntities). When an entity enters the model, I would like each of them to have that information and, as those tasks are done, keep some record that they have been done. I have created a repeat group property within the ModelEntity object to grasp info from infoEntities table and the make use of it. But I have not been able to make it work. Could you provide me with some hints to progress? A model and a document with images is attached. Many thanks. description.pdf model.spfx -
Hello, In my model I have an entity who needs to make different server . Exemple, I want my first entity to go to server 1,2,3,sink and the second entity to goes to server 4,5,6,sink. I want to make a table with multiple choices of sequences and the program will choose randomly the road to go for my entity. I saw videos from the module 6 of simio training. I want to do the same think exept I don't have multiple entity. I have only on entity but multiple sequences possible. Can you help me please ?

Has anyone used "NextEntityOnLink" ? I want to model a chase, where an entity chases another, identifies it, stops it and changes it's direction, or destination.

Hello, In my program, i want to have: source-> waiting zone-> workstation -> sink I have a worker how move the entity between the waiting zone and the sink. My worker also stays at the workstation to make it work during process. But i want to know how can I tell my worker to start processing at the workstation even if there is a entity at the waiting zone. Because actualy if there is something in my waiting zone, the worker will drop his entity at the workstation and go get the other entity in the waiting zone. This way my program can't continue because there is no worker to make my workstation work. Sorry for my bad english .... Thank you !

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!

Hi folks! I'm trying to model a production line with one worker and several stations that he visits/uses. The process is in a specific order (ie, the entities move in a direct path) but the worker is free to float between stations as needed. The situation I'm facing now is that some stations require him during the beginning and ending, excluding processing time, and other use him the whole time. I have a station that he is called to be at, and he goes and completes the task, then exits the station leaving the entities, goes to finish another task, and then returns to the original station to pick up the entities he left before. How do I make him take those entities to their next location before leaving? I've tried setting the "task selection strategy" to "largest priority" and assigning higher priority to the entities at the original station, but it's not working. Any help would be very appreciated! Thanks PS, does anyone have any thoughts/preferences between using processes to seize the worker and delay during the task versus using the station's secondary resources to call him? They seem to be the same thing to me and I was just wondering if there are any tips/tricks/reasons to use one over the other? Double thanks!

Hello, I have created a sub-model with two servers connected by a path that will process n types of entities (i.e. different products that share a work station). In the main model these entities have a table reference assignment (specified at the source) that allows different processing times in each server in the model. If these entities enter the sub-model how can I allow for different processing times? Since there is no source in the sub-model I do not see a way to assign the a reference table (normally done in the source). Thank you for any ideas! -
Hello, I am new to Simio and am having trouble with altering process times which differ according to the Model Entity. First, a little more about the background of the problem. I am trying to model a call center and have 12 different Model Entities that move through Free Space according to a sequence table. So for example, as part of the model I want a single server called "Sales" but there are three model entities that eventually end up at that server, but each is processed differently. Could anyone suggest a method to model this phenomena that doesn't involve adding additional servers? Thanks. Kevin

Hi all, I'm a new user to Simio and am having to give myself a crash course in the software, so please bear with me. I posted this in the material handling forum but have realized that this is probably a better question for the SI Objects forum. My project is a manufacturing facility that involves product being created, processed, and finished in tooling, which is transported between process steps by transporter vehicles. My team is attempting to determine the need for additional tooling and transporters in this facility, and so material handling and resources are the main focus area of the project. Can entities seize resources across multiple workstations? IE, an entity (product) would seize a resource (tooling) out of the Source, and continue seizing that same resource as it travels through several workstations, and then release the resource as the entity enters the Sink? In our facility, the product is supported in tooling as it undergoes multiple operations at different workstations, and we need a way to model the tooling utilization. The transporters can come and go freely while the part/product & tooling combination are in process at each workstation. Is it possible to model this in Simio? Or reasoning behind using the objects the way we are is so that we can track utilization of the tooling and transporters to determine at what production rate they cross the 100% utilization rate threshold. Thanks in advance. -
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 guys, there is someone who knows if is possible create a server process which can identify what kind of entity is just entered in the server? i.e. I have a model where 3 entities are created by the same souce, both of them entered in input in the same server but they have to be processed in a different way so I need to distinguish them. Thank you for your help.

After some experimentation I have figured out how to get entities to interact directly with other entities, without having to add any code on the model level. By using the call: (first entity).location.parent.model.(second entity) inside a search or other process block inside the first entity I can access and manipulate the second entity. Example Model 1 - Ball Toss With Arch Simple Model to show different entities throwing a "ball" back and forth Example Model 2 - RvB Model to show entities "fighting" each other. In this model the entities interact with each other by reducing HP and destroying other entities Ball Toss with Arch.spfx RvBv4.spfx

Hi guys. I have a timer for each entity. I'd like to know the location (object) of each entity whenever its timer is fired. Can somebody give me some clues on how to do this? Thanks.
