Route Optimization Model for Order Picking of Distribution Center

Abstract

This paper studies an optimal model of order picking route to improve picking efficiency and benefit. The model consists of three modules. First of them is the order picking grouping module based on container volume and how many pickings a container can accommodate can be calculated according to the material volume of picking task Second of them is the coordinate model with vertical arrangement warehouse shelves In this part, coordinate model and assorted parameter list can be built according to the location of goods in the warehouse. Third of them is calculating picking route module. This paper also studies how to get the shortest picking route using nearest neighbor strategy to calculate optimal picking order.
