摘要
贵金属材料加工过程具有流程性生产和离散型加工相结合的特征,根据工艺路线特点和多种参数的实际意义,基于启发式算法和极大极小代数法思想,建立融合多目标评价参数的数学模型,将所有订单任务按优化规则进行排序,在兼顾熔炼炉次计划的前提下得到投产顺序。这一贵金属材料加工的排产调度算法可以在保证全部订单有序、高效完成的同时,规范生产过程,降低熔炼费用,保证交货期。通过试验验证了这一算法的有效性和实用性。
Work process of precious metal materials features a combination of process-based production and discrete processing. According to the characteristics of process route and the practical meaning of diversified parameters, a mathematical model with multi-objective evaluation parameters was established based on heuristic algorithm and minimax algebra method. All orders will be sorted out according to the principle of optimality to obtain the production sequence while keeping one eye on the precondition of smelting furnace plan. This scheduling algorithm for processing of precious metal materials can ensure all orders to be completed in high efficiency and in order while standardizing the production process and reducing the cost of smelting the algorithm is effective and with guaranteed delivery term. practical. Through experimental verification it shows that
