具有不确定交货期的供应链协调及效率研究

研究了制造商和销售商组成的二级供应链管理,销售商在有固定长度的销售季节内面临不确定性需求,制造商由于各种不可控因素交货期不能保证。文章建立了交货期延迟情形下制造商对销售商进行收益一致性补偿的模型,对比了分散决策与集中决策下的最优订货量和收益变化。通过算例仿真与数值求解,重点分析了制造商与销售商在应对需求与交货期不确定时,各种不同条件下供应链协调的效率,为企业决策提供理论支持。

Supply Chain Coordination with Delivery Time Uncertainty and Effectiveness Study

We study a two-echelon supply chain that consists of a manufacturer and a seller who is facing uncertain demand in a selling period with a fixed length. Due to a variety of uncontrollable factors, the delivery time is uncertain. We build a revenue consistency compensation model which describes delivery delay situation. Besides, we compare decentralized decision with centralized decisions through the optimal order quantity and revenues changes. Based on a numerical case example, we focus on assessing advantages and limitations of coordination in response to demand and delivery time uncertainty. Thus, a theoretical support for business decisions is provided.
