Pick up entitys in different locations and drop them off to a server
Gashi replied to Gashi's topic in SI General Discussions
Thank you for the quick answer! Yes I know the ABC Costing Calculation in Simio, but I forgot to add, that I want to divide the total transport costs among the individual components that are transported at the same time. I think it would work with the calculation: TransportCostRate / TransportQty * TransportTime , so I just have to track the transport quantity for example with MyVehicle.RideStation.Contents. And my small model is just a example. My goal is to set up a cost analysis tool with calculation of transport costs, bufffer costs, processing costs, ... for finished production models. And for example the buffer costs, i want to use more specific cost rates (footprint dependence for example, ...) The disadvantage of my custom way is that so far I can determine the costs only at certain points (for example pick up and drop off) in time and not "continuously" as it is now with the automatic calculation. Or do you know if there is a way to adjust these "custom" times so that they are also calculated continuously? -
You need to put the search, release and transfer steps into the Add-on Process Triggers "Parent Entered" of the Combiners. For example, for the "Juntar_secos" combiner, at the "Parent Entered" Addon process, you would search for Slots.Processing.Contents, matching "Candidate.ModelEntity.Id_Del_Pedido == ModelEntity.Id_del_pedido". After that you should use a release step, to release Server "Slots", and a transfer step to transfer what have been found to Output@Slots. -
Well, first thing, you don't need your entities to be bouncing between the output and the input of your server like that. If you want to use it as sort of storage, set both the processing time and the capacity to infinity. After that, at the moment that the parent entity enters the combiner "Parent Entered" you could search the queue of your storage using a search step with something like "Server1.Processing.Contents", with the condition of "Candidate.ModelEntity.State == ModelEntity.State", release the server and transfer what have been found to the output. You need to take some care on some situations, like what if the parent entity arrives first at the combiner then the member at the storage? And some care with batching quantities aswell. But I think you can handle it.

Off Shift Rule Secondary Resources
asneath replied to james.waller's topic in SI General Discussions
Double check that each Resource is hooked to the correct Work Schedule, and that you have the intended Day Pattern inputs for Mon - Sun in your Work Schedule(s). It sounds like you might need a separate (two total) Work Schedule for each group of 5 Resources. I would also recommend visually verifying that the Resources go OffShift (turn white) at the intended times. Other than that just make sure that the Off Shift Rule, in the Server's Secondary Resources, is also set to 'Suspend Processing'. Another way to check that the Server has suspended processing is to put some Dynamic Label Text on the Entity like 'ModelEntity.ID' so you can see exactly which Entity is in the Processing.Contents queue of the Server before and after the shift change. It should be the same one! Happy modeling! -
Hi All, I am attempting to model a triage logic where I want to periodically, sequentially search the contents of a storage queue associated with a station and test the availability of resources to handle processing it. If the resources are not available in the system, I would like to move to the next entity in the queue and test it until all the current queue has been examined. The goal is to sequentially walk the queue organized by priority using the lowest value first of a state variable on the entities. Is there a suggested "best" way to approach this sort of problem? Essentially I want to do a loop to examine entities in a storage queue and transfer the best one with a match to available resources. I tried using a search based on index but ran into an error getting the state values of the entity and also seem to have challenges sorting the storage queue correctly. I would be grateful if someone has a basic example of such a sequential search. Thanks Very Much, Jim

New to Simio and learning as I go. The attached model includes a CombinerNode1 that batches entities in groups of 2 & 5 (random.discrete). I would like Server1 to use different processing times for the different batch sizes. For example, a batch of 2 entities should be processed in 5 seconds; Batches of 5 entities in 7 seconds, etc.. Eventually I will create batches of up to 6 entities. I have tried using Server1.Processing.Contents for Processing Time, but seems to return the value of 1 all times. Any help is appreciated! Thanks! Processing time based on BatchSize.spfx

Just curious if there's an easier way to go about doing this... Long story short if I am representing multiple physical positions within capacity of a server and I create my own Gantt outside Simio, it's important for me to know WHICH resource (in this case which one of the servers) is utilized by each entity. I was trying to utilize Entity.Location.Parent.Server.Processing.Contents.IndexOfItem( Entity ) and assigning it to a state on the entity and then ultimately writing to an output table. However, this doesn't seem to be working accurately. It may be a timing issue on when this step is called, but is there a default function I'm just not aware of that could be of assistance?

Testing if resource is seized before releasing it
PierreUL replied to PierreUL's topic in SI General Discussions
With a decide step just before the release step in my process logic, I was able to test if the worker is seized. The condition I used is : ServerName.Processing.Contents.FirstItem.SeizedResources.Contains(WorkerName[1]). So thanks a lot! It's exactly what I needed! -
Testing if resource is seized before releasing it
MEagar replied to PierreUL's topic in SI General Discussions
Remembering that the entity in the processing station is the Owner of the Resources i.e. the server; and all three workers, if you place a watch on the entity and drill into "functions" of the entity in the watch window, you will find the variables for your conditional logic which you seek (see attached). Server.Processing.Contents.FirstItem.ModelEntity.SeizedResources.xxxx should suffice....

Server Processing State Variable
ptkolodziejczyk replied to simiouser1's topic in SI General Discussions
To acess a state variable of an entity that is being processed at a server (let's call it Server1) you should type the following into the label, assuming there is only a single entity at the server: Server1.Processing.Contents.FirstItem.ModelEntity.Name Mind that you will get a warning if you run with such expression in a label, because you will be at times trying to reference an entity at an empty station. Then, you should expand the expression to: Math.if(Server1.Processing.Contents.NumberWaiting != 0, Server1.Processing.Contents.FirstItem.ModelEntity.Name, "") -
Hi, For selecting a available resource from a list of resource you can use a selection expression like 'Candidate.Resource.Capacity.Remaining' and and set the Selection goal to 'Largest Value'. What this will do is, it will give priority to a Resource with highest available capacity ( in this case 1) indicating that a resource is available for seize and seize the available resource. You can use a state variable to track the number of entities that enter the server. Whenever an entity enters the 'Input Buffer' of the server, assign the number of entities present in the buffer and the processing station to a state variable ( Using Server.InputBuffer.Contents+Server.Processing.Contents) and when the entity is leaving the server, decrement the value of the variable by 1. Use a state statistic element to keep time persistent statistic on the state variable. Use Statestatistic in the experiment response to report maximum and average number of entities. If you share this same state and statestatistic across multiple servers, then you will see statistics about ALL the servers. -
Destroying an entity if a failure occurs during service
willem replied to reedrsmith's topic in SI General Discussions
Hi, In the on-failed event of the server, Search the contents of the processing queue, in the found step place a release step in order to release the applicable server. Directly after that place a destroy step to delete the entity, otherwise you can transfer it back to the start. Hope this helps... -
I want to monitor the time a server is idle as a response feature in an experiment. I think the standard Pivot Grid statistics has the "Time Starved" feature which tells me how long the server is idle. But i want the total idle time of all servers as a response in my experiment. So thought i may use a tally statistic with the value "Server1.Processing.Contents==0" but i don't know how to connect that with a property and i am not so sure if that is correct. I think that might be a common interest so maybe you have a solution for that.

Hello everyone, In My Model i attached, i have 4 diffrent type of entities. The model is a standart Source-Workstation-Sink model. In my model, entities come to Workstation2 and afterwards they are processing. In workstation2, if entity type is same, there is no setup time but if entity types are diffrent, there is 2 minute setup time. My question, which is very crucial for me at that time is, after all entities came to Workstation2, is there any way to set a variable how many entity type (as we can see in model, the number is 4) came to Workstation2.Inputbuffer.Contents? Or is there any way to see the number of them in a status label after they come to Workstation2.Inputbuffer.Contents? At that point, you may say that why are you using Tables instead of using ModelEntity for each type of entity. I know that i can do it in that way but if i can built the model at the end, i will have a lot of input. Thats why i preferred using Tables. I don't know if it is a simple question or not. However it makes me crazy because unfortunately i cannot find a way, i'm stuck on it. If anyone have an idea or know solution, please help me. Regards, Alper MyModel.spfx
