设计开发了纸卷分切与库存综合优化系统软件。首先建立了纸卷分切与库存优化的混合整数规划模型,然后设计了在VC++6.0中实现求解混合整数线性规划模型的求解器,并实现求解器同关系数据库的数据交互,最后用GE的智能软件平台iFIX将各功能模块集成为一个基于MES框架的优化控制系统。该系统同ERP层与PCS层进行数据交互,实现信息集成,避免了形成信息孤岛。
Design and development of paper roll slitting and inventory optimization system software. Firstly, a mixed integer programming model of paper slitting and inventory optimization is established. Then a solver is designed to solve the mixed integer linear programming model in VC ++ 6.0, and the data exchange between the solver and the relational database is realized. Finally, The intelligent software platform iFIX integrates each function module into a MES-based optimization control system. The system exchanges data with the ERP and PCS layers to achieve information integration and avoid the formation of information silos.
