The Implementation And Reliability Analysis Of DRP System For Optimizing Inventory Control

With the continous development of market economy, enterprises continue to expand their market scale, reomote production and remote off-site sales increases the difficulties of the management for remote logistics and capital flow.Enterprises are facing larger and larger pressure of market competition,which forces enterprises to give a higher-level information management for supply chain. With Internet technology,based of Internet, a new logistics technology-DRP comes into being..DRP is Distribution Resource Planning for short. It is a new management model which is optimization-based for business process , and aimed to the core of integrated sales and inventory control management, so that enterprises have capacity of fast response to order and delivery ,and continous added to inventory,.It have to ensure that it meets the needs of the market effectively and makes the configuration least cost ,and offers an assurance.for the management of back-end supply chain business.This thesis is in the background of a pharmaceutical enterprise, and make the organic unity of people flow, logistics and information flow based on the enterprise's existing materials management process. The thesis also conducts a comprehensive reunification of distributors, product inventory, reports of this pharmaceutical enterprise, not only achieves accurate tracking information of inventory ,and provides comprehensive information flow for management, but also shortens the company's supply chain and reduces the costs.The paper uses JavaEE framework, adopts MVC pattern, in use of (SSH) Struts + Spring + Hibernate composite frame,use MySQL as the database,based on Ajax,JSP,Servlet,JavaScript and other technologies,do a comprehensive analysis and design from the requirement analysis and the key functions,and meet the needs of the entire business process basically.In this system, we use ABC classification method,combining with enterprise business process and the enterprise's inventory management of the entire supply chain, give an optimize design for inventory management module.we not only complete the realization of fundamental inventory needs,but also save costs of the supply chain ,and improve the efficiency throughout the supply chain.Finally, in use of probability theory, operations research and knowledge of optimization, we analyze the reliability of the whole system, thus ensure that the stability and feasibility of the system in use.
