Vehicle routing problem with simultaneous delivery and pick-up under different weights

In order to solve the enterprise's actual problem and meet the demand under different priority level of new product distribution and old product recycling in business enterprise, This paper improves the traditional vehicle routing problem with simultaneous delivery and pick-up. Considering the importance of the new product distribution and old product recycling in enterprise operation, we put forward the pickup and delivery vehicle routing optimization problem under different weights and establish a mathematical model. With the introduction of power grid enterprise actual calculation example and by using lingo, a software tool to solve mathematical model, for calculating, we analyze and verify the effectiveness of the model and its actual effect.
