针对有限信息共享条件下,供应链协同计划难以实现计划调整的收敛性和达到全局最优的问题,提出一种具有多点搜索和概率搜索特征的协同计划方法。将协商中交流的备选计划及其所产生的成本变化信息融入到计划调整算法中,以遗传算法的选择、交叉和变异过程为调整机制,将算法的迭代过程与计划协商过程结合在一起。在确定上下游企业能力约束多产品批量计划模型和最小累积需求求解方法及其模型的基础上,分析了协同计划过程中的编码、适应度函数、初始计划组生成和选择、交叉、变异算法等主要要素,并给出协同计划流程。通过仿真实验验证了该方法的有效性和相对的优越性。

A collaborative planning approach with multi-point search and probability search character was proposed as it＇s difficult to achieve convergence of plan adjusting and reach global optimization with limited information sharing.It puts the planning transfer each other and the information of related cost changing into arithmetic of plan adjusting,uses selection,crossover and mutation rules of Genetic Arithmetic as adjusted policies,and integrate iterates of arithmetic with plan negotiation.After constructing the multilevel,multi-item capacitated lot sizing problem models for both upstream and downstream and solving method of minimal cumulated require of lot sizing,the main factors of collaborative planning are analyzed,such as coding method,fitness function,obtaining of initial plan suit and selection,crossover,mutation arithmetic.And the collaborative procedure is given.At last,the validity and advantage of the approach are validated with a computational experiment.
