【Abstract】 Boiler product design usually needs reference to previous design cases.Considering this characteristic,the technology and methods for managing boiler design calculation cases were proposed.A case library of boiler design calculation was established by database technology to store and share various design calculation models and results in the boiler manufacturing enterprise,as well as the feedback information about boiler operating and monitoring.By adopting project and scheme as logical unit,the physical structure model and corresponding database design model of the case library were designed.The information management and synchronization between client and server was discussed.The method for retrieving similar reference cases based on nearest neighbor algorithm was studied.Research and application practices show that the proposed technology and methods are efficient for developing the case management system for boiler design calculation,and beneficial to accumulate product design knowledge in boiler manufacturing enterprises and improve the manufacturers’ design level.更多还原
