[Help-glpk] Linear formulation of a small problem

[esma mehiaoui]

Hello,

 

I'm trying to formulate the following small problem by linear constraints , could someone help me to do it?

 

if (A[t'] = 0) then " Z[t,t'] =0 "

if (A[t'] = 1) then " Z[t,t'] = W[t] / sum {i in s{t'}: P[s] * R[s] } " in this case the sum is never 0 because A[t'] != 0

 

 

R[s] is a parameter

W[t] is a real variable

P[s] and A[t'] are boolean variables

 

 

Thank you very much

Best regards
