Question:Capacitated VRP with unknowns (Stochastics) Demands (1)

Hello,

I am trying to solve CVRPSD by integer L shape method. I have some problems.

d=(0, 20,20,25,15,10): Demand
p=(1,1,1/3,1/2,1/4): the probability demand

K=50
1) How to write properly Recourse Policy (Q) in maple (I attached my problem) ? Recourse (Penalty cost) is applied when the demand exceed the vehicle capacity. We know that in CVRPSD, we don't know the demand until vehicle arrive at the node(customer).
(Look at my program)

Hopefully anybody could help me to solve this.

Thank you any way.
