Research On The Management Information System Based On CWBT

With the development of shipping industry and the increasing competition of shipping market, it is required that shipping companies' ship maintenance management is stricter than ever. For many years, the ship maintenance management of our country is similar with the former Soviet Union, which adopt schedule maintenance. This maintenance system is based on the operating time, and ignore the station of equipment. Adopting schedule maintenance, lead more expense and the enterprises emphasize on repair rather than maintenance, emphasize on using rather than management. So it restrict the development of shipping industry and it is extremely urgent to adopt advanced maintenance management to guarantee the ship safety, increase operation rate, decrease the operating cost and strengthen the competitive ability of shipping enterprises.The paper brings forward the maintenance management based on equipment's station by collecting and cleaning up a large of information. And gray model is presented to decide the maintenance cycle coefficient K.Dempster-Shafer evidential theory is also put forward to maintenance decision-making. At the same time it programs the maintenance management system based on equipment's station. The main contents are as follows:1 .It brings forward the maintenance management based on equipment's station by analyzing and summarizing Chinese ship maintenance system and it's application. In this maintenance management, it sorts the maintenance and adopts system and entire management; on the other hand, it takes the different maintenance model on different equipment and makes maintenance plan based on maintenance decision;2. Based on equipment working station monitoring, gray model is presented to decide the maintenance cycle coefficient K3. It presents the decision model of maintenance mode and maintenance type based on Dempster-Shafer evidential theory;4.The paper discusses the functions and structure of maintenancemanagement system based on CWBT. In addition, it presents the project of the designing and management on the database. This system implements the main functions such as maintenance model decision, maintenance type decision, maintenance plan arrangement and database management.
