ABSTRACT

Vehicle routing problem is a kind of common problem in logistics distribution center, in order to solve the high delivery cost of VRP and time constraint problem, the VRP model with the object level and constraints by semi-soft time window is built. Aiming to the semi-soft time window constraints the optimization of the model is discussed. Finally the numerical examples prove the superiority of the semi-soft time window constraints than other types of time window.

Keywords:

Object level, semi-soft time window constraints, VRP.
