考虑时间因素的双目标应急召回闭环网络规划

研究产品召回突发情况下的闭环供应链物流网络规划问题,考虑了产品召回紧迫性以及召回应急管理的管理特性,引入时间和召回率两类随机参数,提出了基于成本的召回处理时间反应函数,建立了基于总成本以及总召回处理反应时间的双目标随机混合整数规划模型.采用一类启发式算法对该模型进行求解,并用Matlab6.5软件进行编程求数值解.在数值解的基础上,进行相关参数的敏感件分析,结果表明网络选址结果具有一定的鲁棒性.

Dual-objective closed-loop network planning model for product recall with time factor

The closed-loop network design problem when the product recall happens is studied. Considering the tight
time schedule and the recall management, two kinds stochastic parameters which are the time length and the recall rate are
introduced. A dual-objective stochastic mixed-integer programming model based on cost-time length function which the
optimal result is decided upon to minimize the sum of cost and the length of total time is established. A heuristic algorithm
is used to solve the problem, and a numerical example is given by using the software Matlab 6.5. The sensitive analysis of
several parameters shows the robustness of the location of recall center result.
