Oct 01, 2006· >has been mentioned about GAMS & CIPLEX I am not good in programming so >wanted to solve the problem in aforesaid softwar Maybe the reason why GAMS and CPLEX are not mentioned is that VRP is not a linear programming problem Actually, LP can be used on various stages of solving process, but VRP is a bit more than LP.
