为降低多级供应链物流成本,优化供应链物流响应周期,研究了带软时间窗约束的多级供应链物流服务资源整合问题。通过满意度函数对供应链物流周期优化结果进行评价,以最大化供应链总体满意度和最小化服务集成商物流本为目标,建立了多目标优化模型。针对该模型,设计N SGA-II算法予以求解。算例分析表明:与供应链物流运作独立决策模型相比,该模型可以实现各级供应链物流运作的有效协同,不仅能减少物流配送延迟时间,还有助于降低物流运作成本。
In order to reduce the logistics cost of multi-level supply chain and optimize the supply chain logistics response cycle, the multi-level supply chain logistics service resource integration problem with soft time window is studied. Satisfaction function is used to evaluate the cycle optimization results of supply chain logistics, and a multi-objective optimization model is established to maximize the overall satisfaction of the supply chain and minimize the volume of service integration business logistics. For the model, N SGA-II algorithm is designed to solve. The case study shows that compared with the independent decision-making model of supply chain logistics operation, the model can achieve effective coordination of supply chain logistics operations at all levels, not only reducing the logistics delivery delay time, but also reducing the logistics operation costs.
