高频直缝电阻焊管企业多阶段生产计划建模及管理信息系统设计

生产计划是企业生产管理的重要起点和依据。为避免以往采用人工排产方式所导致的资源浪费，达到最优排产策略，基于高频直缝电阻焊管（Electric Resistance Welding，ERW）企业的生产特点，针对多阶段生产计划建立了提前/拖期惩罚数学模型。考虑了交货期窗口、库存影响、企业产能、维修停机等约束条件，以惩罚费用最小作为优化生产计划的目标，采用遗传算法有效求解及优化了该问题。利用Visual Studio2010建立B/S模式的管理信息系统对数学模型进行功能实现，通过COM接口将MATLAB与B/S系统联动实现算法嵌入，完成了对生产计划的求解与管理信息系统的开发。管理信息系统在特定企业运用的结果表明：该模型及管理信息系统符合企业生产计划编制需求，达到了预期目标，具有较好的学术价值和实际意义。

Multi-stage Production Plan Modeling and Management Information System Design of Electric Resistant Welding Steel Pipe Enterprises

The production plan, as the start and the proof of production management, aims to avoid manual production planning causing the waste of resources and to achieve the optimal production planning strategy. Based on Electric Resistance Welding (ERW) steel pipe enterprises′ production characteristics, the production plan is optimized. In mathematical modeling, a mathematical model of earliness/tardiness punishment for multi stage production plan was established with the limitation of the due window, inventory, production capacity, maintenance shutdown date etc., aiming to optimize the production plan and to minimize the tardiness punishment. The mathematical model was solved and optimized through genetic algorithm. In developing the management information system, the B/S model information system with Visual Studio 2010 on the basis of the database was created. With the linkage of MATLAB and B/S system through the COM port of MATLAB, the algorithm was perfectly embedded with a user friendly interface and in turn realized the calculation and expression of the production plan. The results show that applied in a specific enterprise, the model and management information system realized the management of the ERW steel pipes enterprises′ orders, inventory and production plan data management, achieving the expected goal, with a good academic value and practical significance.
