MTO模式下受剩余寿命约束的刀具优化调度系统研究

s the MTO model gradually becomes the mainstream production form in the market, how to properly distribute tool resources in a fast and ever-changing production process has become an important issue. In this paper, after carefully analyzing the factors affecting tool life under MTO mode, the tool residual life prediction model based on improved BP algorithm is established. The tool residual life prediction result is taken as the factor affecting tool optimization scheduling, and the constraint of tool remaining life is fully considered. In order to reduce the production cost, a tool scheduling model with the aim of priority selection, tool minimum tool change and minimum tool remaining life variance was established, and a tool based on B/S architecture was built with this core. The intelligent management system realizes the integrated management of tools from procurement to scrapping.
