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.

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

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, 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

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?

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.

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, 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

Greetings, I would like to express the following condition in the Decide step but i couldn't find how; Run.TimeNow - ModelEntity.TimeCreated< 60 (minute) Could you please tell me how to express correctly the 60 minutes ? Best regards,

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.

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

I have a source, called forklift source, that has a varying interarrival time based on the time of day. To do this, I created a time indexed table with the different interarrival times in different rows and the interval period set to one hour. This source also depends on the interarrival time of another source called Newtrucksource, but not on an hourly basis. I am trying to conduct an experiment where the interarrival time of newtrucksource changes with different experiments and a different time indexed interarrival table for source 1 is used for each of these different interarrival times. To do this, I created a real property for newtrucksource's interarrival time and a table property for forkliftsource's time indexed interarrival table. However, I can't get this to work because in the model, the interarrival time property for the forkliftsource must be a "number" and I am referencing a table which comes up as using "string". Trying to find a way to make this work.

Can Simio make runtime versions of models?

Is there any way to find the cumulative off-shift time of any server anytime during the simulation run? Thanks in advance.

Hi! I already know how to determine the expected operation time. The thing is, I want to know how much of that time is left at any given moment, in order to make a decision (to choose which server I should send the following entity). Thanks in advance

Hi All, is there a way to make the server waiting for two (or any defined number) entities to begin the processing? I would like the server to begin processing only when two entities has arrived. Then the two entities leaves the server at the same time, and other two begin being processed. Can I do it without defining a process?

Hi, I need to execute a process only during three hours per day, but I cannot use the timer because It just represent a point in time and I need a period of time Someone can recommend me an simbit, or give me some advice in topic Thanks in advance

Dear Simio employee, I have two questions about 'getting' the average holding time for all the realisations of my subclassed vehicle. I want to know how long an entity is on a vehicle, on average. I tried it with two processes, but both don't work. I don't understand why the following doesn't work (process GemTijdOpAGV): And I also don't understand why the process TijdContainerOpVoertuig doesn't work. I don't understand the error: 'Model Entity does not match the model', or something like that. I created two instances of de model entity, named 'container and pallet', but it seems like I can't use model entity in some processes and in others I can. Why is that and when can you use model entity and when not? (This is also true for instances of a vehicle.) I have attached the model below, but it is still in progress. I hope to hear from you soon! With kind regards, Thomas Haven_v1 project DS model met RS en dus intelligent MTS.spfx

I have a model where I need to set a server had a maximum of 15 entities from 7 A.M to 10 A.M. I Use the WorkSchedule but I don't know how to limit the number of entities. Can someone help me? *This server it is parallel with other servers.

Hi all, I made a model of a production line (starting with 2 servers) and I am wondering whether it is possible to change the processing time of the second server based on the actual output of the first server. Theoretically seen the processing time of the server 2 = Speed of server 1 * E , in which E is a fixed formula (connected to server 2) to correct the speed. So if the first server performs according to expectation (without failures) for example 40 the processing speed of the second server is equal to 40*E with a delay of the conveyor time between server 1 and server 2. If the server has failure and thus have a lower output (for example, 30), I want to change the processing time of the second server accordingly to 30*E with a delay of the conveyor time between server 1 and server 2. Does anybody have an idea of how to do the following: How can you monitor the actual output of the first server at each timestep? Is it possible to fix the proposed formula and use it in an add-on process? How can you take the conveyor time delay into account (using a delay step in the add-on process?)? I am quite new to the software so I am not sure whether it is possible to model this in Simio. Thank you in advance!

Is there a way to create a column of Time property without date using Simio Table, just like the start time and end time of day pattern of the work schedules? The work schedule doesn't suit my needs.

Hello! I want to make the simulation model which illustrates about the interference time about three kinds of truck. And such trucks enter the warehouse and head to the specific loading spot to do forwarding operation with one goods among four kinds. That is why interference time occur, by which I mean that I have to make model to find the most suitable spot for each goods forwarding activity by switching each spot. However I can not find the accurate properties avoiding each other objects at path, or even allocating several time delay on the situation that they encounter. Anyway, I want to see object avoid each other by decelerating its speed and calculate overall time delay at the result tab. (20 seconds per each interference) If I can apply the time delay, the kind of the object does not matter. I already tried to make the entities play a role as the truck that works mentioned above, but that trial was failed because there are no property to decelerate, or avoid at least.. I sincerely want my dear SIMIO to achieve a success in this modeling.. Thank you!

Hello, I have a network with one source and different sinks. I use add on process on the output of my source to choose the sinks based in the capacity. When I run the model, all created entities destroyed in the sinks correctly but in result part, "TimeInSystem" is equal zero. Due to add on process, is it happen?Should I calculate time in system with Tally? Best, Nadere

Hi, I have used the SimBit "InterruptibleOperator" where i have set the process time on the servers to be a fixed one (200 sec at server 1 and 300 sec at server 2). I have further more changes the Interarrival time on source1 to be 1 day and the entities per arrival to 50. The Interarrival time on source2 to be 1 day and the entities per arrival to 100. (Look at the linked file) Then when i checked the process time on the server in results it was not 200 sec and 300 sec as had set it to in the server. I think the operator is the one to blame for this, but how can i get the right result in results? I have tryed to remove the operator and the process connected to it, and then i got the right process time. I however still need the operator, so need a solution to get the process time and keep the operator. InterruptibleOperator - process time - resultat1.spfx
