摘要
在多品种、小批量物料的生产中,需求量往往具有不稳定性.针对未来需求的预测问题,基于时间序列预测法,综合利用数学软件,建立了物料需求的周预测模型并评估了模型精度;针对生产计划的安排问题,引入安全库存概念,并建立了基于安全库存的物料生产计划模型,同时给出了6种物料的生产计划安排方案;考虑到物料的库存需要占用资金,分别讨论了安全库存与服务水平、占用资金与服务水平的关系,并结合两种关系,选出各物料的最佳安全库存,重新优化了6种物料的生产计划.
In the production of multi-variety and small-batch materials,the demand is often unstable.Aiming at the problem of future demand forecasting,this paper establishes the weekly forecast model of material demand based on time series forecasting method and comprehensive use of mathematical software,and evaluates the model accuracy.In this paper,the concept of safety inventory is introduced,and the material production planning model based on safety inventory is established.At the same time,the production planning scheme of 6 kinds of materials is given.Considering that the inventory of materials needs to occupy funds,this paper discusses the relationship between safety inventory and service level,and the relationship between capital and service level,and selects the best safety inventory of each material based on the two relationships,and re-optimizes the production plan of 6 kinds of materials.
