I'm making a call center simio model. The 7 types of calls are generated at sources and then move down a path to a server. This server represents a queue that is formed at the call center. After the queue server the calls are transferred to 1 of 7 desks (which are represented by a server) where a call agent is working. How do I make it so the calls do not go to one of the server desks until a desk becomes available. As it currently stands the calls go right through the queue server and build up at some desks even if there are free desks available. -
Hi everyone! In the project I'm developing I need something similar to what was done on the Simbit "EntityFollowsSequence". The difference is that I need to be able to change the destinations (update the contents of the sequence table) over time (the number of rows of the table can be fixed, although it would be ideal if they could be dynamically created). Could someone please explain how it would be possible to do this? My edition is NOT Enterprise. Thanks.

Hello there, this is my first post here and I hope someone can help me with my problem. I´m quite new to Simio and working on my first project. I have some "return entities" that are considered "bad" at the end of the production. So they will get collected in a server which is used as a storage and get returned to the factory every 24 hours, to get reworked, if there is capacity left. Now, I want to check if there is capacity left in the destinated server and in best case, reserve the needed capacity before, before I route these entities towards it. After the entity arrived in the server, the reserved capacity should get released again. I couldn´t find a good example here in the forum or via google search, as in the SimBits, how to solve this the correct way. Maybe someone here can give me a tip, how to. Thanks in advance. Aljonator

hello :), I'm trying to make a model with three servers. Everyone uses different Workers type and have different operation time per entity (no problem in these points). The difficult part is the next, every work center (server) has a different setup and changeover, and both happens without the presence of the entity. I mean the setup of some servers starts when the entity is created, (before the arrival to that server), and after the operation the changeover has to be done, in both cases we need to use or assing a worker. How can I do that?

First of all, Thank you so much for the answer in advance, but could I bother anyone who answers with some example model or picture of the method I am still new to SIMIO, so I am concerned about following the advice correctly. 1) Let's say every day I have X number of people arriving( using distribution to generate numbers outside SIMIO randomly). This is the shop where people visit from 8.00 to 20.00 every day with different visit rates per hour (example as below), and I use X to time to this percentage so I can get the exact number of visits per hour. The problem is I want to make an arrival interval random with some sort of function/distribution or table(excel calculation), not a stable arrival rate. My idea is random from 0 to 1 and gives the random number (Y) to match with X outside SIMIO and put the whole table in, but I wonder, is there any better method than this? 2) The second question is about two entities from different sources, A and B. A and B will go through the same server for three servers, but after server 3, one will go to 4, and one will go to 5. Can you give me any advice on how to do that

Hi all, I have a model with several servers, each with their own Changeover Matrix for cleaning between jobs. This is done by a Sequence Dependent Setup within the Servers Task Sequence steps. This is working fine when the Cleaning is either done 100% Automatic or 100% Manual with a Worker called as a Secondary resource. Some servers however require partial support from a Worker. For example a COMatrix of X mins needs to include 5 mins support from a Worker at the start and 10 mins support from a worker at the end of the Changeover period, with the middle X - 15 mins in the middle of the CO cleaning period (There are other more complex examples too where the operator will be required half way through the process too to empty the cleaning waste container). Is there a way of saving the COMatrix time, rather than running this delay, so that I can then build an add on process or add further task sequences to break the time into its Automated and Manual Components? Thanks in advance for any suggestions. J

I have a table that allowcate 5 gates will have different entity will launch in specify date and time. How can i do it ? We are designing a airport simulate aircraft departure its gate.
-
We are simulating the aircraft will leaving the gate according to our real data history. How can i import the table in simio and let the aircraft leave the gate accouring to the time and date? Also some gate will have more than one different time and date that aircraft will departure the gate. How can i do it as well?

Hi everyone, I am trying to model entities moving from 10 origins (sources) to 10 destinations (sinks). The entities are simultaneously created according to a certain mix (Entity1 (85%), Entity2 (10%), and Entity3 (5%). However, the number of entities created per event is according to a certain distribution. There is an OD-matrix that captures the number of entities moving from origin to a specific destination. Let's say there are 10 destinations, than the destinations of the Entities are determined according to the OD-matrix: Entity1 and Entity2 can move to any of of the sinks. Entity3 can only move to one specific sink. One solution I came up with was to add weights to Connectors and assign destinations using TransferNodes, but I think that this is very inefficient. I then started to work with DataTables, but I cannot figure out how to probabilistically assign the destinations of the entities. My question is: how to model the probabilistic destination assignment of Entities using DataTables in such a way that it is relatively easy and flexible to add or remove Sources/Sinks? I have added the model for you to see, I hope that you can help me! Many thanks in advance Simple_OD_creation.spfx

I am doing a Final Year Project with Simio. Our topic is discusing the taxiway routing problem to enhance aircraft congustion in the taxiway. Our group are the new to use simio, when we want to do some simulation on the taxiway, we dont know how to increse the same distence between different space of the entity(ie. airplane) in the path(ie. Taxiway). Also how to make the entity stay in the path while waiting the privious plane leave the runway? We would like to do the silulation like this video https://www.simio.com/applications/airports-and-airlines-simulation-software/ 1:08-1:30 Any one can help us?

Hey Simio insiders, I have been working on a model with workers. The workers transport goods over a facility, from one server to another. They seem to work perfectly until about 2 hours into the simulation. I have been looking into the the 'watch' properties, and it appears that the worker is waiting for something. This happens eventough i do not have a wait process in place. It waits at a server which it is about to drop an entity. The server input buffer is infinity, since i thought it might have caused the problem. Do any of you know why my worker is waiting?

Hi, I'm trying to keep track of the time traveled of each vehicle in my system. I'm attaching a basic file with the current model. Aly help will be highly appreciated. Nw_Working_All_Logic.spfx

Hello, I'm new to both the forum and the world of simio in general. I am trying to simulate how much the maximum buffer could be in 2 points of my process which are defined by the Buffer_ST1 and Buffer_ST2 servers. My problem is that I would like the Buffer_ST2 server based on a condition that would be every time an entity passes on Input @ Buffer_ST1, the Buffer_ST2 server releases only one processed entity and not all those inside the server as it happens now, I hope for being clear and thank you in advance. I put the model in the attachment Buffer varianti trazioni V2.spfx

Hello, please I need your help. I have a combiner in my model called Revisar_pedido, which fulfills its function without any problem until, at one point, an entity enters (Pedido_PU.597) and gets stuck inside it and I can't understand why it doesn't come out. I already checked the functions, processes and states and nothing seems wrong. I attach my model for better understanding. Beforehand thank you very much. 06.11.spfx -
I want to build a simple repository model,as the Picture below. And there are two Funktions, that i donn't know, how to implement. The first Problem is: I hope that several products with different total amount can be generated in sequence one by one. For Example, there are 50 Product A, 40 Product B and 30 Product C at Source WE. They schould be generated in sequence. First 50 Product A,1,2,3...50 one by one generated. Then 40B, generated one by one and finally C. At present, I can only achieve one-time generation of all A, then all B and All C. The second Problem ist: there are may be 10 Vehicles in the System. I want to record the total time of the car loaded and empty travel time, and the corresponding percentage of these two items. I would be very very grateful if you could help. I'm really in a hurry and hope to get your help.

How can I model where the robot always pick 2 parts and waits until 2 parts are available at output buffer of the server. (Robot is available in extras library). i have multiple servers in the model.

Hey, I've got a quick question on how to route to a combiner with the longest waiting time in their parent queue. I think it should be quite easy, but i cant seem to make it work. What i have been doing is setting the selection goal of my routing node to largest value, and select from a list. This largest value I think should be the the longest waiting time in the contents of the parentinput queue. I have tried this multiple ways both using assosiated object and without. When i recall the number waiting it seems to work, but with recalling the waiting time i'm doing something wrong. My current expression is: Candidate.Node.AssociatedObject.Combiner.ParentInputBuffer.Contents.TimeWaiting(ModelEntity) or Candidate.Combiner.ParentInputBuffer.Contents.TimeWaiting( object ) both seem to work for content.numberwaiting. I think i am describing the ( object ) part wrong but cant find how i should write for the modelentity otherwise. I have tried to recall a specific entititype like so --> TimeWaiting(Truck) this also does not work. Does somebody know how i can acces the ParentInputBuffer.Contents.TimeWaiting? Greeting Piet

Hi! can you help me please? In my model I have a server that I want to function as storage, this server is linked to a combiner which will combine the member entities that leave the server with a parent entity that will arrive at it from another node. Each member entity has a state with a unique number linking it to a parent entity (there may be more than one member entity with the same state number). How can I extract from the server only the member entities whose state is equal to the state of the parent entity that arrives at the parentinput of the combiner? Thank you so much! 18.10.spfx

Hi! In my model I have entities called "Pedido" which have a state called "id_del_pedido" which is equal to the ID of the entity. These entities will enter a Separator that will create copies of the entity according to a probability distribution. Since the new entities are copies of the parent entity, they will have the same "id_del_pedido" status as the parent entity. Subsequently, the entities created will enter a Server that acts as a warehouse. This Server is linked to a Combiner, when the parent entity reaches the Combiner's parentinput I want only entities whose "id_del_pedido" is equal to the ID of the entity that reached the Combiner's parentinput to leave the server. This works perfectly in the first Server-Combiner set of my model, but, the Combiner's outputnode is attached to another Combiner and I want to repeat the same activity as in the first Combiner but I get an error that I don't know how to solve. I attach my model so that my problem is better understood. Thank you very much in advance! 18.10.spfx

Hello Everyone, please can someone help me with this situation? I want to use a Server as a storage place, entities coming out of it go into the MemberInput of a Combiner. I want the number of entities that leave the Server to depend on the state of the entity that will enter the ParentInput of the Combiner. How can I access the state of the parent entity that will enter the combiner from the Output Node of the Server? Thank you very much, Greetings! 14.10.spfx

I wonder if it is possible to pick one particular entity from the BatchMembersQeue and unbatch it. For example I have a pallet with 10 entities batched (9 red and 1 blue) and I want to remove only the blue one. I was able to find the entity with a search step, but I cannot transfer it or unbach it. Any ideas? TnksUnbatch one entity.spfx

Hi, I'm having trouble with unit conversion when doing state assignments at a source. There are two different cases where this problem appears in the model: Subtracting TimeNow minus a Date Time state variable (ModelEntity.stWaitingListEntryDate) Although the specified unit for this property is 'Days', the assigned value is in hours and the unit is also 'Hours'. If I manually convert it by dividing by 24, the assigned value is in days, but the displayed unit is still ‘Hours’. Unit conversion issue when assigning a new value to a state variable from a data table Although the PatientsData.MaxWaitingTime is a real property with default unit ‘Days’, the assigned value to the state variable is converted to ‘Hours’. As in the first case, if I manually convert it by dividing by 24, the assigned value is in days, but the displayed unit is still ‘Hours’. In the attached model (time_units_conversion.spfx) you will find a simple example where you can see this in more detail. Any suggestions to solve this issue will be highly appreciated. Thank you and best regards, Nicolina

Hi, I want to generate one type of product with one interarrival time. I have one source and one model entity. However, this entity can have different lengths following probabilities. Depending on these properties, the processing times at the servers will be shorter or longer. I tried to assign a state to the entity before this entity exits the source so ModelEntity.Length becomes DataLength.prob.randomrow. where DataLength is a table with the different lengths and the probabilities associated with those Lengths. The only thing is that it is a property and not a state, but I do not know how to do it in another way. Afterwards, I have different processing times at the servers depending on the different characteristics of my entity. For example, server1 will have different processing times depending on the length. How can I reference to the good processing time say I have added a column to the table DataLength with the associated processingtimes according to the lengths? Finally, I would also like keep track of those different lengths generated and see what the model produced in the end. Thank you for your help, Emilie -

I'm interested in calculating a yearly production rate. Essentially I could do this if I ran my simulation for 1 year and looked at the output. The number of entities destroyed by my "completed" sink will be what I'm looking for. How do I determine this value if I'm running for longer than 1 year? For example; If I run for 5 years, and I'm watching my model run, at week 186 I'd like to know how many entities had been destroyed by my "completed" sink between weeks 134 and 186 to determine my yearly production rate.
