Dear all,
how to code matrix X properly? I want the index of element of matrix is obtained from set S. Since s = {1,5,6}, in matrix X, i should get x11,x15,x16 and so on.
Do you know how to solve this?

Thank you anyway

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.

Hello,

I got problem how to rewrite formula in maple, I have tried so many times but it is not working.

How to rewrite sum of double sum like this formula (4th constraints in the following picture)

H := numelems(N); for k from 2 to H do for i to k-1 do cons[k] := add(x[i, k], i = N)+add(x[k, j], N) = 2 end do end do;
                             H := 5
Error, invalid input: add received {1, 2, 3, 4, 5}, which is not valid for its 2nd argument, i
