The scope of this paper is to propose a development of vehicle routing for perishable items. Due to the fact that operators incline to choose rout near the lodging, we proposed VRP with weighted nodes. The coordination of production scheduling and delivery planning becomes a controversial issue in the perishable food industry with the aim of minimizing vehicle travel cost. We used Lingo 8.0 to solve small size problem. The related results (cost and CPU time) are illustrated and showed the effectiveness of the proposed method, finally
