| Bid and quotation are decision problem, which synthesized multifactor including qualitative analysis, quantitative calculation, decision-maker's experiences etc. The competition of bid market become more and more drastic. And bidders need conform a reasonable and competitive price of products in good time. It plays an decisive role in which enterprises exploit market, boost up competitive abilities and gain favorable economic benefits.Decision support system, which base computers and give priority to decision-maker , is a human-computer interaction information system. Its elements include data, knowledge, methods, models, and decision-makers, and mostly use to solve segmental structured and non-structured decision problems. Presently, the mainstream of human-computer interaction technique is graphical user interface. Database is the datum aggregation which is stored in computers choronically, organized and shared. And it can be used by several people under differrent right-limits. Model library is used to store decision models. Graphic library stores three-dimensional solid graphics and planar drawings of electromechanical equipment's parts , and unitedly manage them. That can enhance the human-computer interaction abilities of decision support system.The subject studied in the knowledge of decision support system, project bid, software programme exploiture and database expoiture. On a basis of that, it studied configurations of decision support system frame, discussed the usability of DSS at electromechanical equipment project bid, established database about electromechanic equipment, design a new type reasonable frame of electromechanical equipment project bid decision support system, and mark off system function modules.The subject used RDBMS software SQL Sever2000 to create database and graphic library of electromechanical equipment's parts. It designed lectromechanical equipment PBDSS under the integrated design environment of programme language... |
