Storage assignment and optimization research of AS/RS based on a Hybrid Tabu Search algorithm

Automated storage and retrieval system (ASRS) is an important element of modern logistics system. In this paper, based on the analysis of input output operation of ASRS, a hybrid tabu search (HTS) algorithm is put forward to solve the problem of storage assignment. First, a heuristic algorithm is developed to generate the initial solution of storage assignment and then a tabu search algorithm is designed to obtain the optimized solution, which could improve greatly the efficiency of the ASRS. To illustrate the effectiveness of the proposed method, a case study is presented.
