摘要:

考虑由两个供应商和一个装配商所组成的装配系统,且装配系统在供应商管理库存模式下运作。考虑仅一个供应商产出不确定和两个供应商产出均不确定时的两种决策情形,研究了每种情形下供应商的最优生产投入量决策。在此基础上,讨论了装配商的承诺订货量契约和供应商的补货策略对供应商最优生产投入量、装配系统各成员期望利润等的影响。研究结果表明:在两种决策情形下,满足特定条件时,装配商引入承诺订货量契约后能够实现装配系统性能的帕累托改进;仅一个供应商产出不确定时,装配商选择的任一大于市场需求的承诺订货量都唯一对应着一个缺货成本边界,如果实际缺货成本超过该边界,则装配商能在该承诺订货量下获得相对于未引入承诺订货量契约时更高的期望利润;供应商的补货策略总能实现装配系统性能的帕累托改进。

Abstract:

The timely supply of various components is the key to the efficient operation for the assembly system. However, the supplier’s yield uncertainty makes the timely supply of the components unable to be guaranteed, and the insufficient supply of any kind of the component will lead to the failure of the assembly. Moreover, many assembly systems operate under vendor-managed inventory (VMI) mode, which makes production decisions more difficult for the supplier whose yield is uncertain. Thus, the suppliers’ production decisions in the assembly system are studied under VMI mode while considering yield uncertainty. An assembly system with two suppliers and one assembler is constructed, and the system operates under VMI. Two different situations are analyzed: Only one supplier’s yield is uncertain and both suppliers’ yields are uncertain. In each situation, the assembler’s commitment order quantity contract and the supplier’s replenishment strategy are adopted separately in an attempt to improve the performance of the assembly system. Both suppliers’ optimal input decisions in different cases are obtained. On this basis, the effects of the assembler’s commitment order quantity contract and suppliers’ replenishment strategy on the suppliers’ optimal input quantities and the assembly system members’ expected profits are discussed. The results show that: in the two situations, the assembly system can achieve a Pareto improvement under specific conditions after introducing the commitment order quantity contract; when only one supplier’s yield is uncertain, for any given commitment order quantity higher than the market demand, there exists a corresponding boundary value of the shortage cost, and if the actual shortage cost exceeds this boundary, the assembler can obtain a higher expected profit by introducing the commitment order quantity contract; the supplier’s replenishment strategy can always lead to a Pareto improvement of the assembly system. Furthermore, main conclusions are verified by numerical analysis. In general, the cooperation schemes provided in this paper can effectively cope with the supplier’s yield uncertainty in the assembly system and it is expected to improve the competitiveness of the assembly system in practice.
