The large-scale logistic center has played an important role in the mail order and Internet dealing system. In order to ship products based on customer order papers within due days, it is requested to control the logistic center effectively. This study focuses on the order-picking problem, one of problems efficiently to control the logistic center. A new criterion "Energy Minimization" is introduced into this problem. Then, LCO (Local Clustering Optimization) is applied to solve the problems. Based on above, this study is extended to the re-scheduling when urgent interrupt orders are requested. A re-scheduling method is proposed how the urgent interrupt orders are assigned and mixed into pre-determined schedule the proposed method based on LCO as well. The influence by the urgent interrupt is examined by simulation experiments, and we prove the effectiveness of the proposed method.
