Hi! I'm sea, making some user-defined selection rule. I wonder that what is the exact meaning of "based on entity ID" in your question. is it same as creation sequence, like order date? I know original value expression was "Candidate.Entity.Priority" in the dynamic selection rule. But I'm not sure that is oriented from arrival sequence at specific buffer.

I'm pretty sure my whole approach is flawed, but I don't see how else to do this. The attached is a very simplified version of what I'm trying to do. In the real problem, I have empty containers that enter a detached queue based on when they are retrieved from customers. I also have workers that need to select (through a fairly complicated process) which of these containers to batch together to enter a filling station. This selection process is complicated because it depends on filling material, pressure, volume, and safety stock of the sku (multiple skus can be combined in same batch provided filling material, pressure, and volume of container match). Anyway, what I'm aiming for is Create a batch When the worker is idle, he will go to a node and search among empty containers in the detached queue to assemble a complete batch. If there aren't enough containers, the worker will wait, idle. As empty containers arrive at the detached queue, they should trigger, somehow, the worker to try to create a batch again. There are new containers now, so maybe a batch is possible. (Preferably, since hundreds of containers could arrive at a time, this trigger would be for all the containers arriving at this specific time, not each container doing a separate trigger.) With the batch, the worker should move to a server, seize it and wait while the containers are filled. Then move to a separator to separate out the batch, moving the containers to full inventory and the worker should go back to try to create another batch. I'm stuck in a couple of places, specifically (so far) . . . I can't seem to get the worker, once batched, to move to the filling station. In fact, the Move block in PickingStation_Entered doesn't even fire. I can't figure out how to get the entity to trigger the worker to reevaluate the batching process. However I try this, the batching process is executed by either the entity's token or a model token. I can't see how to get the worker to be the executing token. Any help or guidance would be appreciated. Model.spfx

i want to find the original object name (without instantiation or population eg. just Ca123) is this possible ? how ? ( from CA123.35357 to just CA123 uising expressions, CA123 belongs to CustomTruck model)

If you have a batched entity (through Batch step or Combiner object), there is only one parent entity and the rest member entities. Thus, one entity exits the parent node, the others exit the member node. If the Separator instead did a Make Copies instead of the Split Batch, you still have the original parent entity (incoming entity) and the member entities (copies). If you need to split the entities in different directions, you should look at having both of those nodes connected to a single node where you then make the decision to go in two different directions.

1) Depending on how the entity is created in the first place, that assignment may already have been made. So, for example, if the table includes the arrival time and is used as an arrival table within a Source (Arrival Mode is set to 'Arrival Table'), then the entity that is created automatically has a row reference to the arrival table row from which it was created. Alternatively, if you create an entity, you can use the SetRow step to assign it a specific row in a specific table. ** The entity doesn't ever become a token ** Please refer to the Tokens page and the Tokens and Entities page within Simio help for more information. Tokens can be associated with entities (or with a model if a process is triggered by a timer, event, etc.) 2) If the entity has a row reference within a data table, simply referring to the TableName.ColumnName to access the table information is sufficient. This will automatically retrieve the information in the TableName table, ColumnName column at the designated row that the entity has a reference. If the entity doesn't have a reference within that table, Simio will give an error if you attempt to refer to the data in that fashion. Alternatively, you could reference a TableName[RowNumber].ColumnName to specifically reference a given RowNumber. Refer to Data Tables page within Simio help for more information.

I have 3 questions: 1) I have a data table, each row representing an entity to be created. I create several entities and assign each of them to each row in this data table, using a SetRow Process. I have read somewhere that after I set a row to an entity, it becomes or token? So what is a token exactly? 2) Also, after a created entity is set to a row in the data table, is there any special syntax I can use to make reference to values in other columns in this row? Or I still need to keep track of which row in the data table the entity is set to and make the references using the normal table referencing syntax accordingly? Thank you !

Hello, there! I'm quite new to Simio. I saw "SchedulingDiscretePartProduction" example recently and noticed that there was B2MML data schema which was very impressive. So, What i have wondered is whether the data schema in the example is exactly same as B2MML data schema. Or, are there some changes from original schema? In addition, does anybody know where to get some information about B2MML data schema? Thank you. Jay.

you can use a create step for making a copy of your original entity. Also, you can use seperator object for the same purpose. You can look around simbits by using create step or seperator keywords.

I'm new to Simio. I'm trying to split my original entity into two different parts. The goal is to have the entity be separated, with half of them having a different server processing times through the same server.

Hi, You can even use process logic in Evaluating Seize Request AddOn on server. and set Token.ReturnValue=FALSE if the incoming ModelEntity does not fit your criteria..

Dear Flora, I build a sample model to interrupt a task and afterwards resume that task with the remaining processing time pls kindly find the attched model. thanks! I am not quite understanding your approach, however the error you mentioned is the token is not targeting at Worker, thus the error... InterruptingTaskExample_byJeff2.spfx

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

First define a real state variable to your modelentity named "livingtime" after its creation. Then make a copy of your modelentity and send the copy of modelentity to a process (maybe called as death_process). Place a delay step and set delay time as modelentity.livingtime. Of course the original one should go its way. Then place a search step and find the original modelenity in the system when the time is up at delay step (while finding the original entity you should set a match condition such as candidate.modelentity.ID==modelentity.ID etc. I am not sure whether the ID's of both entities are same, you should try. If it does not work you should try to match creation times of them (both should be same) or any other user defined state variables or properties). If the search is succesful make necessary controls (i.e., if it owned any resource release them etc.) by placing necessary steps following found branch. You should remove and transfer the found modelentity (it is the original one) to appropriate place. At the end you should place a destroy step following the original branch or even transfer it to appriate place. It depends on your goals.

You cannot hold an token associated with an entity at the SetNode step in a process. The token can be held at a Wait step or Scan step.

Your original problem stated: It seems the best and simplest approach is illustrated in SimBit SelectEntityTypeFromTable . Your table would have 10 rows, one for each entity type. You would add a 2nd column to hold the weight or frequency of selection for each entity type. Set your MaximumArrival on the source to 900 to avoid any overload.

subclass a workstation object, override perform teardown activity process of this subclassed object then at the end of the process steps (before the transfer step) use only one create step then assign the type of the created modelentity to swarf (place an assign step to the end of the created branch of create step and also tie this branch to the transfer step if it is required) and assign the original modelentity type to part (if it is required)... this will ensure that all of the operations (setup, processing and teardown) occur on the single part, and THEN two separate entities are made?

You can use two Create steps within a process to create two different types of entities and simply destroy the original entity when you no longer need it. Assign step can be used to assign information to the new entities that you may wish to transfer from the original entity.

Yes, in Simio sprint 159, which was published at the end of July, we enhanced the RemoveRows step so that you can remove an active row in an output table, based on the object type specified, such as associated object, token, etc.

What you can do is within the Worker object's 'Evaluating Seize Request' add-on process, create a process. This process will then be called each time the worker is deciding whether to take on the entity seize request being made (if not, it will try again next time worker becomes available). Add the following steps to the process: Add a Decide step with Expression 'Entity.Location.Parent == Server2 && (Server1.InputBuffer.Contents > 0) ' - the Entity.Location.Parent will determine if the requesting entity is at Server2 and if so, if the Server1.InputBuffer has anyone in it - and if so, that means there are higher priority items to be worked on at the Server1. From the True exit of the Decide , add an Assign step to assign the State variable 'Token.ReturnValue' to be the value of 'False' or '0'. This means that the entity request for the worker will be false (for this particular evaluation) - when the queue at Server1 resides, and the evaluation is again done, the token will exit the False exit of the Decide and the entity at Server2 will be able to seize the worker.

Hello, I have a process Vehicle1_EnteredNode that moves a vehicle and seizes the two workers needed to operate. The two workers work from 8 to 12 and 13 to 17. When they are off the schedule, process AAInterruptCarMove is used to interrupt and release correctly the server and the vehicle. To make the Interrupt process, I’ve checked simbit VehicleStopsWhenServerOffshift. Then, I’ve used process AAInterruptGrutierEtAccrocheur to interrupt and release the two workers. The problem is, the two workers don’t get released. Instead, they go offshiftBusy which I don’t want because while OffshiftBusy, they are considered as being utilized. In that process, I've released the token associated with them but does not work. Any clue for me on how to get them released? I’ve put the model on this link : https://drive.google.com/open?id=1yZSFbqUlreh1v6oyG5Jy7AYzTrTBbBUS Thank you

Your logic is fully right. But, you have to send an entity (or any token) to the processevent to fire your event. Examine the sample model I attached. OnRunInitialized process I created an entity and by using this entity I activated the process1 to fire the event. You should apply this type of logic. sample model.spfx

You could use the add-on process for the worker named Evaluating Seize Request that would check the size of the queue where the customers are waiting (and I assume this is where they are requesting the worker to bring beer) - and if the size of the queue is not at least 2, then refuse the request (assign the 'Token.ReturnValue' to 'False' or '0'). The below info was taken from the help on resources (which is similar for workers/vehicles used in a seize manner as well). Evaluating Seize Request Add On Process In the Resource object from the standard object library, there is an Add On Process called Evaluating Seize Request. This Add On Process is executed when the object is evaluating whether to accept or reject the capacity allocation request. In the executed decision process, the user should assign a value of less than or equal to '0' to the executing token’s Return Value state (Token.ReturnValue) to indicate that the allocation attempt is rejected. The value '1' indicates that the allocation attempt was successful.

In the Search step, if you are trying to search the entities within the member input buffer, you should have the Collection Type set to 'QueueState' and then the Queue State Name set to 'CombinerName.MemberInputBuffer.Contents'. I don't think that queue is automatically in the pull down list, but you can type the name in directly. This will then search only the entities in that queue and provide a token exit out of the found representing each (given you set the Limit property to Infinity to search for all entities in the queue and not just the first one).

Petr, I tried out your updated version, as I had used Glen's original in the past. There is definitely a speed boost with this version. My "test" import file is the 25 X 25 grid attached (625 BasicNode and 1200 Path Objects.) On my old laptop this imports in about 60 seconds. I noticed that the progress bar works great for the Objects sheet, however it does not appear to update when the Links are imported. The progress remains at 0 while the links are imported, though the routine works and I see the dialogue at the end with no errors. The nodes only take about 10 seconds to import and the links constitute the remaining ~ 50 seconds. I tried turning off visibility of the links/arrows, but this made no difference. I haven’t tried vertices yet. Also, note that I had to re-build the add-in in Visual Studio, as I seem to have an issue with adding add-in .dll's from an outside source to my ..\SimioUserExtensions directory. Hopefully I did not break the application in the process. Thank you very much - this is very useful! 25 X 25 Grid Import.xlsx

Is the search step being executed? Have you tried a break point on that step? If tokens are entering that step but not exiting through either the "original" or the "found" branch that would imply a pretty major bug, I think Can you post an example model demonstrating the behavior you are seeing? -Adam
