供应链的协作供应问题研究

当供应链某活动环节的物资需求量过大时, 一个供应点常常不能提供其全部所需物资.因此, 实际应用中需要多个供应点共同参与. 针对供应链物资需求的特点, 提出了多点协作供应的数学模型, 通过引入可行方案的定义, 给出了可行方案存在的判定定理, 以及可行方案的构造方法. 然而一个可行方案可能包含太多的供应点(太多的供应点有时意味着较高的生产准备费用) , 因此该方案可能并不实用. 考虑到方案可靠性及费用, 给出了求取优化方案的一个启发式方法. 最后对模型的系统软件集成进行了简单探讨

When the quan tity of requiremen ts by an activ ity in a supply cha in is too large, a soledepot usua lly can not prov ide a ll the requiremen ts, and it ismuch practica l for in troduc ing multiple depo t s to m eet theneeds.
