RCPCP model

[mohamadrafei]

hi
i want to simulate a RCPSP(Resource Constrained Project Scheduling Problem). i defined the products as activities that this activities entered to the Multiserver and there time of the activities alocated to them. But since there are resource constraints the time of each activity should be determined with the constraint. I 'm at the bottom of the model defined a source that is used to generate the resources needed . It is a renewable resource. this means , for example, every month there is a constant supply. But I do not know how relevant these resource constraints to carry out activities. Also, because some activities are done simultaneously i have used a multiserver. I appreciate if you can help me.

Hi Mohamad,

The cycle time of the Multiservice atom can be based on a label.
So, you could assign cylcetimes to products in a label. For example, on the trigger on creation:

Code: Select all

Label([LabelName], i) := Bernoulli(50,10,100)

A product that enters the Multiservice is last in line when its cylce time is determined.
Therefore, you should use:

Code: Select all

Label([LabelName], Last(c))
