  1. Anyone has a solution for this? I still didn't figure out an easy way to get many workers with individual schedules where each worker has its own start and end time. Especially when I want to run my simulation for multiple weeks I need a way to get this from my Excel data file into my model.
  2. I got a file where each worker has a unique ID for every time they work, and a start and end time of their shift. I also converted to to time intervals and the amount of workers that are working at that particular time interval. I tried using the table based schedule for both tables, but this does not seem to work since all workers get the same start and end time.. Your method requires many different workers for the same process, each with their specific work schedule which looks like a lot of work for something that looks quite simple... Is there no easier way to do this ? Thanks for the quick reply!
  3. I have multiple workers for different tasks and I want the workers to work according to different work schedules. When I use the work schedule option, all workers of one process use the same work schedule. In the examples they use different workers for each shift, but since workers come and go at different time during the day this would require a lot of different workers for each process.. For a server the capacity of the server can be changed during the simulation, is there a way to do the same for the amount of workers in the system? Or let each worker work according to their own custom work schedule imported from a table?
  4. I added the monitoring function, and using add on processes I got the model working the way I want now! Maybe you guys can give some feedback on the model and tell me if this is the best way to model this? I only modeled one gate now, but I got some questions when scaling up for multiple gates: When I'm trying to make a subclass of Gate 1 the processes stay in the global model. I tried to define the processes within the subclass, and use referenced property as input for the workers (like you would do normally when using sub classes?), but I think it doesn't work like this with processes? What is the best way to scale up my model without having to add processes for each new gate? Since I do not use secondary resources within the server anymore, but add-on processes, my constraints do not show in the planning tab anymore. I can think of some ways to get this in there but is there no setting within the server which I have to turn on / adjust to automatically get this in there ? Thanks! TestModelWorkers_2.spfx
  5. I'm trying to model airport ground operations using workers for the different processes, servers for the gates, entities for arriving airplanes and TransferNodes to control the flow of entities and workers. My research is focused on the control of these ground processes, but I can't get my process logic correct.. I attached a simple model to help answering the question. I want the workers to move to the right server before the entity arrives there and can immediately start processing the entities. One method is to use a global queue from which workers decide which entity to process next based on some criteria and dynamic rule selection. In the attached model I use two entities which go to Gate1 and Gate2. Gate 1 needs workers move to the node before it can start processing, Gate 2 does not. Using an add-on process, I move the worker to the gate before it is requested and wait for the entity to arrive. But for some reason it does not start processing immediately when the entity arrives and I can't figure out how to model this correctly.. It's the first time I'm using Simio, so I some help would be appreciated on how to set up the logic for my processes.. I'm kinda stuck now on how to get some basics thing in my model right or if I'm using the right processes steps.. Thanks in advance! TestModelWorkers.spfx
  6. I want to model the ground operations at an airport and looking for the best way to do this. I use a source and sink for each gate which uses the arrival and departure schedule of the airport. When an aircraft arrives at the gate multiple tasks need to be performed (fueling, cleaning, (un)loading, etc...), some can be performed in parallel and some in sequence. I made a flow chart to find dependencies between different tasks and which tasks can be performed in parallel, but I have some problems to get this into a working Simio model. I think the best way to do this is by using a "parent" entity for each flight, which consists of a set of tasks (which depends on destination, load, type of aircraft, etc.) but i can't figure out a way to this. From the support ribbon I looked at the SimBits about Task Sequences for the modelling of the different tasks at an aircraft, and the Secondary Resources and Workers to model the workers and equipment. I'm new to Simio, so any help is appreciated!
