With development of logistics technology, warehouse management has become a critical activity in logistics to outperform competitors. However nowadays warehouse is supervised manually or in the state of semi-automation and the level of visualization and security is not high. Aiming at the present situation, the paper proposes an optimized warehouse management system based on RFID and WebGIS, which improves the automatization, visualization and security.The elementary technology of RFID and WebGIS are introduced at first. In order to solve the collision problem of large numbers of electronic tags, this paper does in-depth research on the anti-collision algorithm. In order to reduce the search times, a reformative breadth-first dynamic binary search algorithm is presented. Experiment results show that the performance is improved.In order to improve the distributed query for WebGIS, the paper proposes an integrated strategy to access distributed spatial data sets basd on dual-cache mechanism. Cache consistency policies are combined with the cache replacement policies in order to improve the overall performance, an algorithm called WebGIS dual-cache consistency and replacement algorithm is proposed, in which the cache consistency policy is adaptive TTL mechanism, while the cache replacement policy is based on a cost/value model. Experiment results show that great performance optimization can be achieved.At the end of this paper, we give an Integrated Warehouse Management System based on RFID and WebGIS and provide the details of it.The research has been successfully applied in a department management system.
