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。
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.
