摘　　要：考虑存货影响需求率,建立了时变拖后供给条件下的易变质品生产库存,证明其局部最优解是全局最优解并运用算例对主要参数进行了灵敏度分析.A production-inventory model is presented by proposing a time-dependent backlogging rate to make theory more applicable in practice on the condition that the consumers are served on the principle ＂First come, first served＂, where production rate is constant and the demand rate is stock-dependent. The effects of obsolescence are taken into account. A necessary condition to determine the Optimal solution is provided. A sensitivity analysis of the optimal solution with respect to parameters of the system is carried out.
