供给不可靠条件下基于数量弹性契约的军品订货决策研究

Research on Military Optimal Ordering Policy Under Quantity Flexible Contract with Unreliable Supply

考虑军事供应链中零部件供应商供给的不可靠性,建立了供给不可靠条件下基于数量弹性契约的军品订货决策模型,得到了装备制造商在不可靠数量弹性契约下的最优订货量和期望利润。研究结果表明：装备制造商的最优订货量与零部件供应商的供给可靠性间的关系非单调,装备制造商的最优期望利润随着零部件供应商供给可靠性的增大而增大。最后通过数值分析进一步验证了所得结论。

Considering the unreliable supply, the military optimal ordering policy model under quantity flexible contract is formulated. The optimal ordering quantity and the expectation profit of the equipment manufacture are obtained from the model. The results show that the relationship between the optimal ordering quantity of the equipment manufacturer and the military components supplier＇s supply reliability is non-monotony, and the equipment manufacturer＇s optimal expected profit increase with the supply reliability. At last, the conclusions get further proved through numerical analysis.
