热轧无缝钢管生产作业计划研究

某钢管企业现有计划工作完全由手工完成，计划不够及时准确。ERP虽然能够有效改善企业的生产作业性能，但因热轧无缝钢管生产具有复杂生产工艺和多品种小批量的特点，使得该企业引进的ERP软件其标准计划流程又不完全适用于钢管企业的生产作业计划和实际。本文对谊企业的现有手工计划流程进行了分析，对生产作业计划流程进行了重新设计，指出钢管生产作业计划实质是组批、划分炉次和确定各炉次的生产日期(班别)，并提出了组批的原则以及划分炉次和确定各炉次的生产日期(班别)的方法与公式。

Research on Hot Rolling Seamless Steel Tube Production Scheduling

The current production scheduling in a hot rolling seamless steel tube enterprise is manually completed and is not timely and accurate. Although ERP can effectively improve the production performance of the enterprise, the standard production scheduling flow of ERP software introduced by the enterprise is not completely applicable to production scheduling and practice for the production of hot rolling seamless steel tube which covers three main characters: complicated production process, multi varieties and low volume. In this paper, the current manual production scheduling flow is analyzed, the production scheduling flow is redesigned, and the essentials of hot rolling seamless steel tube production scheduling are pointed out to be batching, dividing furnace number and identifying production date/shift of every furnace. Finally, the batching rules as well as the methods/formulas of dividing furnace number and identifying production date/shift of every furnace are presented.
