Ware Location Optimization And Management Of AS/RS

As an excellent product of the development of modem logistics and automatic technology，Automatic Storage and Retrieval System（AS/RS），which integrates the storage，transition and distribution as a whole，is an important element of modern logistics．It has developed very fast and represents the current logistics development trend．Storage management is a key link in logistics enterprises，which plays a crucial role in improving logistics efficiency of the whole enterprise．However, AS/RS is also a complex integrated automated system．Its scheduling will directly affects the operation efficiency of the whole systems．In order to improve overall operational efficiency, more effective management should be taken in AS/RS．Goods allocation and combination of goods chain and goods allocation should be optimized to reduce the handling and storage costs，the backlog of capital and the time wasted during storing and handling process，thus reducing the entire cost of logistics and improving the benefits．So researches on the scheduling problems of AS/RS have significant value in the field of engineering application．Based on large numbers of others research about scheduling strategy on warehouse，optimization of warehouse storage slotting and output‐picking is studied，and a logical solution is put forward．The main task of this thesis is briefly described as follows．1．On the basis of summary of slotting optimization and warehouse management studied by domestic and foreign scholars, the current situation and trend of warehouse management are studied in the paper.2．Manage the entering of goods and establish operation procedure. According to the allocation of goods, set up a optimized allocation model aiming at the stability of shelf and efficiency of access. Based on the method for solving multi‐objective optimization problem （MOP）, the MOP is transformed into single‐objective optimization problem.3．Schedule the delivery of good from warehouse and establish operation procedure. For the position optimization problem of outbound order picking，the picking strategy in delivery process is analyzed based on the study of automated warehouse．A new mathematical function model is established for the goal of achieving the shortest walking distance of retrieval machine．4．Manage the goods in stock; introduce Max‐algebra and some of its attributions. And explain them in different way; analyze the meaning and function of each formula. Firstly, sequence goods through scheduling model, and then sequence goods according to the distance from goods to entrance of storage, and finally, couple goods and their allocation. Thereby shorten the time of delivery of cargo from storage and improve the efficiency of logistics.
