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

Perhaps its a little late, but attached is a possible solution to your problem. This started out pretty simple. The problem was how to specify which server is serviced by which resource. One way to do that is a table. But since its changing over time I chose to use a time-indexed table, that is a table that knows about time and returns different data at different times. In this case, each row corresponds to 12 hours and each column specifies the resource needed by the respective server. As they say, "the devil is in the detail" and in this case the "devil" is that the specified resource may change between seize and release (e.g., seize at 11:59, release at 12:05). Simio doesn't like that and all the easy options re-evaluate the resource expression on release and so may try to release the wrong resource. One option would have been to create a custom server, but that seems to be overkill. Here is a somewhat simpler approach: 1) Add an entity state named MyResource and assign it at the last possible moment before use. This value will be used only for release. The assigned value is drawn from the table using an expression like Table1.S1Resource.TimeIndexedValue.Object. Note that the .timeindexedvalue indicates to get the value associated with the current time. And the .object at the end is used to tell Simio to return that value as an object not a number. 2) Use Secondary Resources - Other Resource Seizes to seize the name specified in the table using the same expression above Table1.S1Resource.TimeIndexedValue.Object. 3) Use Secondary Resources - Other Resource Releases to release the resource saved in MyResource.

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

Hello, I'm having strugles trying to configure the setup for the next process: some entities have a diferent processing time and setup time, before to enter to be processed in the workcenters, the workcenter have to be cleaned. I looked the simbit, "ServerWithSequenceDependenrSetup" but I'm confused with the configuration of the processing task. I dont know why we have two lines and o why only one have associeted the change-over matrix.

That's because there is a routing table in this case. That's how it was set in this simbit before I made the updates. I also I tried to set the "Routing Table" as the initial sequence for the entity and I'm still getting the same error.

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, everyone I am developing a postgraduate project related to hospital OPD simulation. In one examination room, there will have a round 5 to 6 doctor using this room during the week. Now I am facing one problem, because every doctor process have difference processing time(function) as picture below(The number is doctor ID). Is there any method to set a difference process time during every shift in one server? or I have to create a process for this them?

there are several easy ways to do this. 1) Subclass the Resource or Worker object with the only change is to add a property or state (ex PTime) to hold the processing time specific to that resource. 2) Put your process times in a table and reference the correct table row for the doctor that is working. The SimBit WorkerPoolWithEfficiency does something somewhat similar.

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 All I would like help to build a custom (subclassed) node that, OnInitialized, would populate a lists of inbound and outbound path in each node. Ideally, it would also determine and store each path's length or travel time, and whether the path is available or not (this would probably require a subclassed path as well). I want this done dynamically (automatically) because I will likely have hundreds of nodes in my model and populating (and re-populating) these lists would be very time consuming and not very conducive to an efficient design process where paths and nodes would be added/subtracted throughout the design process. First, I guess, actually...is dynamic list population possible? Any thoughts? Thanks

A basic photo eye object that can be used with conveyor belts. Photo eye is based on a transfer node object. It collects statistics on time in blocked state, cleared state and throughput. Transfer nodes on entered and on exited add on processes can be used as on blocking and on clearing add on processes. Photo eye has properties to define the delays for on blocked and on cleared. Photo eye will wait to complete on blocked delay to execute on blocked add on process. Similarly, photo eye will wait to complete on cleared delay to execute on cleared add on process.

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

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 know it's been a while, but I just came across this question and I'm responding in case this can help someone else. Depending on the problem, modeling nurses as patient capacity might not work; for example, if you need to limit both a nurse's active utilization and the nurse's patient load. Two general approaches exist: Easier: Create two different resources, rename one 'NursesActive' and the other 'NursesPassive.' Set the latter to have n times the capacity of the former, where n is the patient ratio at n:1. Require simultaneous seizure of one of each type of resource when first assigning the patient, and release them separately, re-seizing the former as needed. Harder: Subclass the Resource object and create states to track the patients assigned and a property to define the patient ratio. This approach enables more fine-tuning as necessary.

Hi, everyone Hi, everyone I am developing a postgraduate project related to hospital OPD simulation. After collecting each table/room process time, convert all the data into an Excel sheet. I am curious is SIMIO has any tool to analyze the best-fit function from the data (time related) I gathered. Thanks.

I used the "DashboardForScheduling" simbit as an example for this case. For the order that is using "FinishedGoodA" material, I want to change the sequence after the welding process is complete if both shape stations are not available. So, I created an alternative sequence table and referenced in the process logic I created. Whenever this happens, I get same type of error message. Do you think this is happening because the normal routing table is referenced at the source object?

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.

Ok I can do a trace and see what I find. Also, I do have different entity/job types getting processed. In my routing tables, I do have the entities specified in the table. I'm trying to use the "ChooseAlternateSequence" simbit as a reference. Is it possible to do this if you have more than one entity type?
