Study about turnover box task assignment model in the scattered picking system

Abstract

Order picking operation has become the key technical breakthrough with the development of distribution center. In this paper, taking into account the wide range of applications, the scattered picking system of distribution center is chosen as the research object, one turnover box is corresponding to the one packaging box in the system. We attempted to maximize the space utilization of the packaging box by designing the turnover box task assignment model. We developed a Clark-Wright heuristic algorithm to solve the turnover box task assignment model on the premise of ensuring efficiency, and introduce an actual case to do some experimental analysis. The experimental results show that the packaging box space utilization can be promoted greatly through the optimization. Therefore we verified the feasibility and validity of the algorithm eventually.
