I have an entity type. 50% of that entity is one counter type while the other 50% is two counter type. After the entity exits the server, 50% must exit while the other 50% must go to the second counter. How do i do this thanks

Hello, firstly a short discription of my problem: I have different assignmeent for different Entity which will take a random time and start after the Entity got processed at Server 1. The assignment can be done during the whole time but has to be paused while the Entity is processed at Server 2. After that the Entity can work on the assignment again. To get processed at Server 3 the Entity needs to be finished with the assignment. To be honest I have no clue on how to even start with this problem and would be very thanksfull for any idea or simbit suggestions? -
Hi, Have an issue relating to trying to track a segmented entity with the camera. I've attached a very simple model that demonstrates the problem. As soon as i set the draw type to 'Segemented' the camera tracking just doesn't work. One possible solution i am aware of is to simulate the segmented object as individual entities. In the context of what i'm trying to do this creates a lot of additional complexity that i don't want to address. Any other bright ideas? Thanks, Lucas Camera Tracking Segmented Entity.spfx

Hi, I have a bottleneck at the end of my assembly line. I cannot dupplicate that station as my total number of workers is already high. Before hiring, I would like to try and reallocate and have satellite employees. I want to allocate my workers to that station when the input buffer has exceeded one entity. Every worker has to finish the entity they are presently working on at the other stations and the first workers that are done need to go the bottleneck station. The rest of the time, the workers can be allocated based on the smallest distance to the work stations. The bottleneck station usually requests 4 workers. That information is already set up in a table. When there is two entities in queue in that buffer, I want workers to be able to go finish the work and hence increase the processing time by X. I have tried a lot of different things, and all my data is stored in relational tables. Thanks! -
Hi, We want to track the avererage waiting time from when an entity is created until it allocated to a server. We already have the waiting time in formula TimeNow - Model.Entity, but we can't figure out how to get it in the results grid so that we can see the average waiting time. Apoteksimulering (1).spfx

I have a series of gated processes that are defined in a sequence table. Occasionally sequential gates will use the same server. In our process, the entity doesn't actually move out of the server, but in Simio the entity has to exit the server and re-enter. What winds up happening is that if another entity is queuing for that server, it will enter first during the approximately 2 seconds it takes for the entity to travel from the output node to the input node , causing the entity that was in the server to queue. I would like the entity to stay in the server through multiple gates, according to the routing logic, without getting bumped by other entities in the queue. It's important to keep the gates separated instead of combining them into a single entry on the routing table, because I need to look at performance statistics for each gate separately. Thank you

In the attached model, I want to transfer entities to stations depending on some criteria defined in a table. I have 2 types of entities, "A" and "B", defined in a table as primary keys. Also I have 2 states, "Good" or "Bad", also in a table as primary key. Finally I have 3 stations. I have a table that has 3 columns, “Entity_Type”, “Quality_Type” and “Station”. For example a row could be "A"; "Good"; "Station 1". It is possible for entity "A" with "Good" quality to end up in either "Station 1" or "Station 2", and in that case I want to randomly select one. The problem is that I cannot use a RandomRow based in more than one criteria. Either I use RandomRow for the rows of the table that are type "A" or quality "Good", but I am not finding a way to do more than one combination. This model is a simplification of the real model which is more complex and has hundreds of combinations. Model_RandomRow_FilteredTable.spfx

Generating new entinty in combiner
Khaled Khamis replied to xdabroar's topic in SI General Discussions
Hi, A combiner is able to combine 1 or more entities into a parent entity. The number of entities that are batched together is specified in the property Batch Quantity. I recommend looking at the SimBit "Combine Multiple Entity Types Onto Pallets" for an example. Best, Khaled -
Worker stagnates after some simulation time

Hey, Thank you for your reply. I have fixed the problem! It was a process that I forgot to stop after a WAIT step. Stupid mistake, but it happens. Thanks -
Hi All, I have a query. Is there a way to implement logic that allows the model to vary the processing time of a server as a function of the available man power? In my model I have various servers and all need a specific number of workers in order to begin processing. I have one large pool of workers to be shared between all stations. This means that there are times when all the workers are in use and times when some are spare. Ideally I would like to model that when there are men spare they would come and help other stations and get the job done quicker or when only some of the required quota of workers are seized they can start the work all be it at slower pace until the full quota has been seized. I hope this makes sense Thanks

My simulation has one entity - patients. Each patient is assigned to a state that defines their patient class, but this state is to be updated every three hours. The probability of moving to a state in the future is dependent on the current state, so it's a classic Marcov chain. Right now I have a very complicated and error-prone process that models the state reassignment logic. It involves many conditional and probabilistic decision nodes with manually entered numbers and subsequent assignment nodes. I would like to clean this process to reduce the probability of programming error by using data tables, but cannot figure out how to do so. Is it possible to reference entity states in a data table to model the decision-making?

Hi, I want to have a source that creates entities according to a date. But also, I want each entity to carry some information like Code, Processing Time and Type. It is possible to do that? And After, how I can use the information that each entity carry? For example, Each entity has their own processing time (according to the table), how I can use that procesing time in a server? Thanks for your help!!! -
Hello Javiera, Based on how the model is set up, Guardian_1 and Guardian_2 follow Work Schedules with specific Day Patterns. Looking through the Trace lines, it appears that Pedido_PU.597 arrives and seizes Guardian_1 which, not much longer after it was seized, was scheduled to go off shift based on Work Schedules. The current Off Shift Rule is 'Suspend Processing' which causes the entity being processed to be suspended until the exact Resource is back on shift. To allow the entity to choose an alternative on shift resource, the Off Shift Rule property can be changed it to 'Switch Resources if Possible'. Best Regards, Khaled

Hi all!, would you help me with this? I want to do a discrete simulation of the current situation in a Hospital in the inpatient unit. I have the data of one year of patients, (over 18,000 people) and I want to use that data in the simulation. That would make more easy to model the server processing times, while we will use the real server times and sequences that each patient had, instead to use probabilities and distributions for the sequence and server times respectively. So, I created a table where each row represent a patient with a sequence (which bed he was assigned due to his level of acuity) and the time that he spent in that bed before he was dispatched. The are more times involve, but we can focus in those parameters to have it more simple. So, the table have the patient name (entity) ,bed (sequence) and Length of Stay in the bed (server processing time). I don't know if is possible that when I create each entity, I can assign, based on that table, the sequence and the server processing time for each patient. How I can do that? Thanks for your time and help

Hello Can simio use time series data (say from an excel file) as cost input for servers, that updates every hour?

Hi, I'm working on an airport simulation, this is my first simulation, i have a transfer node that has one income link and two output links, so I would like to know if there is a way that depending on certain Entinty's boolean state variable, whe passing throught the tranfer node if the state is true set and specific outbound link and if it is false then set the outbound link rule by link weight.

hello i'm the simio user in south korea i want to make my model flexibily. My model has vehicle and elevator The overall process flow is vehicle take entities to server1, After vehicle arrived to server1, elevator take entities and go to every destination. To work well, Three things are needed for this trend First, i want to do if the vehicle comes to server1 then the elevator goes to upstair Second, the vehecle has to wait until the elevator after been to upstair and arrive to server1 Third, repeat the two steps. how can i solve the problem this model in Model2, not Model1 1veh1eleModel.spfx

Hello, I am trying to imitate what you can see in a factory. For example, I created a couple of materials that could be produced and consumed. Process: I created materials. For definitions, I created a produced material that will get the material from a table. Afterwards, I selected a task processing(sequence) under server. I added all the materials that needed to be produced. On task sequence I selected the materials tab to consume each material, but all the entities are running under 40 different materials. My desired output is to see only 1 entity running producing and consuming 1 raw material. Joshua

Hi, I am new to Simio. I was trying to add a routing decision in my model based on average time waiting at a server. But this function only shows up in the status label but not when I try to use it in the Processes as shown in the images. An entity reaching a node should choose the route to a server which has minimum average time waiting. What I am trying to achieve is to create a dynamic routing so that the average Time in System of the entity will be minimized. I don't know whether this is the right method or if we need to work with API or functions to achieve this. Any help would be much appreciated. Thank you in advance.

Hi, I have different type of entities queue up at an server output content waiting for a worker comes to pick them up for further process. After picking up, each entity will be sent to the corresponding location for further process. Ex: Product A goes to Server A, Product B goes to Server B ...etc. Can I pick up the entity based on the condition of capacity remaininig of the destination? Ex: Suppose we have 4 products A, B, A, C queue up. When the worker comes to pick up the first product A, he will check the capacity remainig of the destination Server A. If there is still capacity in the Server A, then go. If there is no capacity in the Server A, the worker go check the second product B and see if there is capacity in the Server B... etc. Can someone give me some idea how I can do this? Thanks for the help! -
I'm making a simple simulation model of a hospital and I'm having trouble with the routing of my model. For instance, a patient first goes through ED and then to OR. if there is no room in the OR, then the patient must stay in ED. How can I model this? I don't want the patient to wait at any input or output buffer, because then it assumes that the ED bed that the patient used to stay in is now free but it actually isn't. Each bed is modeled as a server and there are more ED beds than there are OR beds. Naturally, all ED beds connect to a single transfer node, which then connect to all OR beds. -
Hi, In my project, I have the (main) model of object type 'fixed' and a model of object type 'server'. In one of the processes executed by the model 'server', I want to add a search step that searches a specific entity in the entity population of the main model. How can I do this? Thanks in advance! Kind regards, Christa

Hi All, It's been a while since I have last used Simio and I have an issue that I think should be simple. I have two entities running on a production line, one gets processed by a server and the second entity type moves through the same server almost like a conveyor with no processing. I can work around this by adding another conveyor around the server, but in real life the product does flow through this server and eats at it's capacity. Is there anyway to set up different processing times for multiple entity types on a server? Thanks, Brendan -
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 -
Hi, I’m using a Process type: Task sequence in my model at Server 1. I’d like to interrupt the server each 12 hours for 4 hours and resume the entity being processed later. I’ve used a Timer and an Interrupt step which work perfectly only when the Process type is Specific time. Therefore, I tried with a token to obtain the Interruption at the server. I made a process (InterruptServer) doing so but I feel like I’m missing some understanding here. I’ve received an error message as you can see in the small model. Anyone knows how to solve this error? Thank’s Flora InterruptSeverAndEntity-ProcessTypeTaskSequence.spfx
