GA Sequence of worker pool

Solution Partner Creator Solution Partner Creator

Hello everyone,

 

I am trying to examine the effect of changing the sequence of the creation table in worker Pool object on the results of the model. I want to use a GA. Does anyone know how to insert the creation table of worker Pool to Optimization parameters (problem definition).

 

Regards

Shimon

this is useless

Plant Simulation creates all Workers before the experiment starts; so the order of the workers in the creation table will not change the results of the experiment.

Steffen,

Thank you for the answer,

But I think that the sequence of creation table in worker pool does matter, for example

Suppose there is a list of two workers,

worker1 provides service b1_1 and b1_2 (as an additional service).

worker2 provides service only b1_2

Suppose that station 1 requires service b1_2 Plant will assign worker 1 to perform work at station 1.

At station 2 there is a requirement for a b1_1 service.

In this case there will be no workers left to do the job at station 2 but,

If the sequence of the list was reversed all the stations would have received workers.

In my model I have 20 to 30 workers, each workers has additional services. Our goal is to examine the number of missing employees, so in another different sequence of the table we may receive different results. A real example, a garage that provides service to many types of cars and each employee has a license to certain categories of cars.

 

Tanks and best regards

as a first step have a look into the example collection
Resource - Worker - Manpower

There you can see the change of the creation table using SimTalk.
In your case, the creation table needs to be a TableFile in the frame to be able to change it using the GA. In the configuration method of the Experiment Manager you need to transfer the external Creation Table into the workerpool (Experiment Manager - Advanced Settings - Settings - Use configuration method).
