Automated warehouse storage assignment policy based on storage frequency and workload balance

Abstract

Storage assignment policy will directly affect the order-picking efficiency and logistics cost in an automated warehouse. Based on the traditional storage assignment policies which are focused on the storage frequency, we take workload balance into consideration and propose two new storage assignment policies for the automated warehouse. By analyzing and calculating, it is discovered that new storage assignment policy can effectively reduce roadway congestion, improve the warehouse workload balance and the operation efficiency.
