摘要
为求解多产品环境下带顺序相关调整时间(成本)的递阶生产计划问题,提出了一个两层模型。上层的综合生产计划模型求得各产品类在各时段的生产计划,下层的族分解模型则将上层得到的计划分解到所属的各产品族。为避免当族分解模型中各产品族间的调整时间较大时,上层得到的综合计划不可行,将调整上层计划所带来的额外费用集成到族分解模型的目标函数中,从而可以最优地调整得到综合计划。最后,利用某模具制造企业的数据进行了验证,结果表明,所提出的递阶生产计划模型比整体的方法求解规模小,比传统的递阶生产计划模型的成本低。
To solve the problem of Hierarchical Production Planning（HPP） with sequence-dependent setup in a multi-product environment,a two-tiered model,including Aggregate Production Planning（APP） and Family Disaggregation Planning（FDP）,was proposed.The APP model was aimed to obtain the aggregate production plan of each product type in each period.In FDP model,the APP was disaggregated into the specific lot sizing plan and schedule for each product family.In order to avoid the infeasibility due to longer adjustment time for various product families,the extra costs arising from the adjustment of APP were integrated into the objective function of FDP model so as to obtain the optimal adjustment plans.The performance of the adjustment was validated with data from a mould manufacturing enterprise.The proposed HPP model reduced the solution scale compared to the monolithic approach and realized more cost savings than traditional HPP models.
