The Study On Multi-purpose Computer Aided System

This subject aims at some practical difficulties in marine execution which are reflected by crews. For example,when a ship get to a port ,several certificates could be examined. There are many other problems .The procedures of examination are so complex that it takes a long time foe the ship to wait in the port and when checking a ship or carrying out punishments, the officers have a heavy working intensity compared with a low efficiency and quality. In this case, with the use of Windows98, many tools such as DELPHI, COOLEDIT, SQL, PHOTOSHOP5.0 are used to develop a multi-purpose computer aided system. It can check the safty of marines, punish wrong marine executions, inquire data statistics, use civilized words and look through the marine laws. It's computer to take the place of traditional hand working.By means of storaging the basic technological information and dynamic working data of a ship, and through building up the correspondence between the marine execution laws and illegal actions, practical reliable computer softwares accomplish. "Three Ones" and "Three Zeroes", the former stand for: the papers of wrong writing, wrong use of applicable rules and illegal procedures are zero. Those softmarces simplify the procedures, reduce the waiting time of ships and lighten the working of marine workers. They ensure the punisment in execution to be fair and open. They increase the standard and quality of working. The subject innovates the thread of administration in marine, fills up the blank in the country. In practice, the prominent economy effects which takes the leading among confreres are achieved.Chapter One makes an introduction of the origin and background of the subject;Chapter Two discusses the theoretical accordings and methods of the subject research; Chapter Three carries out a general design towards ten model pieces of many functions which the system would accomplish; Chapter Four introduces the detailed designing process and the specific achievements of main function; Chapter Five pays more attention to the introduction of test ways and results; Chapter Six sums up ten creative ideas and makes a conclusion in the research. It forsees the wide use of the system in the future. Also it optimistically makes an objective analysis of the defects of the system.
