碩士 === 大葉大學 === 機械工程研究所碩士班 === 93 === The purpose of this thesis is to develop a Decision Support System (DSS) for metal press machines. This system can provide each individual press’s information, which includes the operating status, error messages and the health index, to suggest the adequate manufacturing scheduling through website technology. The operation system of this setup is Microsoft Windows XP Professional. PHP Hypertext Preprocessor (PHP) is combined with MySQL database to form the needed software system. The on-site information are transfered to relational database and normalized. The efficiency of database is enhanced and only half of the data storage is needed. The health index for each individual press machine is a join index, which includes the frequency of error occureuce, technical difficulties of error correction and durations of abnormality. This index can provide the needed information for manufacturing scheduling and adequate maintenance. Also the index can be utilized to carry out the short term or long term decision analysis if needed.
