超薄铝箔加工的动态集成排产方法

超薄铝箔的制造具有流程性生产、离散加工和装配生产的特征,根据其工艺路线特点,建立了基于极大极小代数法的数学模型,推导出状态变化的迭代公式,归纳了多目标的评价指数,用启发式方法将全部订单按照一定的规则进行优化排序,并产生炉次计划,使得订单能够及时交货,且降低了能耗。该排产方法集成了生产排序和装炉计划,能够在生产中随时动态地调整或增减计划的投入,在线控制生产。

Dynamic Integration Scheduling Methods of Ultra-thin Aluminum Foil Processing

Ultra-thin aluminum foil manufacturing is the production with some characteristics of flow processing, discrete processing, assembly. Based on these features, a mathematical model was established based on minimax algebra, which could derive the state iterative formula and summarize the multi-objective evaluation index. The model used heuristic method to make the orders in accordance with rules to optimize schedule and generated heat treatment plan, which made the orders timely-delivered and energy saving. This approach integrated schedule and loading furnace production plan, and the production could be controlled online when it was adjusted dynamically or changed for order input.
