Study On B/S-based Management Information System Of Ship Maintenance

At the end of the year 2001, China entered the World Trade Organization, which created an essential opportunity for the domestic shipping industry. Moreover, China is also meeting a great challenge. Ship management mode in China hangs behind, and the information technology employed is in a low state. Ship maintenance management is an important part of ship management. Today, various technologies are being developed at a very high speed. However, ship maintenance management on many ships is still handled by hand, which makes it impossible the immediate delivery and share of data between vessel and seacoast. The increasing competition in the international shipping market drives the ship maintenance to be a new kind of productivity and a method through which high benefit can be easily obtained at a low cost. It is also tremendously vital to guarantee the ship safety, increase operation rate, decrease the operating cost and strengthen the competitive ability of shipping enterprises. Therefore it is extremely urgent to make more researches on web-based management information system of ship maintenance.In the beginning, the significance of this research is analyzed .The content and task are described. In the second chapter, different technologies used to establish Browser/Server-based management information system are compared. Finally ASP(Active Server Pages) is selected. With the designing process of the system, a method to design business service layer, based on the analysis of function pages, is given. In the third chapter, Modern theory of maintenance is introduced. Ship maintenance system (CWBT) and Planned Maintenance System (PMS) are analyzed. Then the implementing of PMS on the ship with CWBT is described. In the fourth chapter, it is deeply studied that how is maintenance cycle reasonable. With the reasonable assumption a simplified calculating way is made. In the fifth chapter, the Browser/Server-based management information system of PMS is designed in detail. Itis carried out in chapter six. The summary and prospect are described in chapter seven.
