【摘要】：研究了市场需求随机且对销售价格及提前期敏感的条件下,供应链如何制定最优的销售价格、提前期以及库存因子使得利润最大化。首先,分析了集中决策与分散决策供应链的最优决策,发现集中决策与分散决策模式下的提前期与库存因子是相同的,但分散决策下的销售价格更高、期望利润更低,且分散决策与集中决策供应链的利润之比随着需求对价格的敏感程度的增大而增大。然后建立了收入共享与成本分担的协调机制,并分析了其最优决策。研究发现,协调决策机制可以有效地压缩提前期,并能同时使供应链达到帕累托改进,但不能达到完美协调,而且还发现协调决策下制定的最优销售价格比分散决策要低。最后通过数值计算对三种供应链决策模式下的绩效进行了比较分析,结果表明供应链利润随着需求方差增大而减小,提前期压缩程度随着材料成本承担比例增大而增大。上述结论可以为企业制定销售价格与提前期决策以及企业间的协调提供有益的指导。
[Abstract]:Under the condition of random market demand and sensitivity to sales price and lead time, how to make the optimal sales price, lead time and inventory factor to maximize the profit in the supply chain is studied.Firstly, the optimal decision of centralized and decentralized decision chain is analyzed. It is found that the lead time and inventory factor are the same in centralized decision and decentralized decision mode, but the sales price is higher and the expected profit is lower under decentralized decision.The profit ratio of decentralized and centralized decision chains increases with the increasing sensitivity of demand to price.Then the coordination mechanism of revenue sharing and cost sharing is established and its optimal decision is analyzed.It is found that the coordinated decision-making mechanism can effectively reduce the lead time and make the supply chain achieve Pareto improvement but not perfect coordination. It is also found that the optimal sales price under the coordinated decision is lower than the decentralized decision.The results show that the profit of supply chain decreases with the increase of demand variance, and the compression degree of lead time increases with the increase of material cost.These conclusions can provide useful guidance for enterprises to make sales price and lead time decision and coordination among enterprises.
