Deterioration rate is an important characteristic of perishable products. While deterioration in perishables is unavoidable, there are proven ways to lower their deterioration rates. Deterioration rate is commonly treated as an exogenous parameter in extant inventory management literature. We define deterioration rate as one of the controllable variables and propose a novel freshness-preservation effort (FPE) indicator. We consider perishable inventory management with FPE for deterioration control decision support. Our results show that there exists an optimal order quantity that minimizes total cost for a controlled deterioration scenario. The optimal FPE indicator value and the optimal order quantity are investigated through numerical analysis. We perform sensitivity analysis and conclude with related managerial implications.

劣化率是易腐产品的重要特征。尽管不可避免地导致易腐品变质，但已经有降低其变质率的成熟方法。在现有库存管理文献中，劣化率通常被视为外在参数。我们将变质率定义为可控变量之一，并提出了一种新颖的保鲜努力指标（FPE）。我们考虑使用FPE进行易腐库存管理，以提供对劣化控制决策的支持。我们的结果表明，存在一个最优的订购数量，该数量可以在受控退化情况下最大程度地降低总成本。通过数值分析研究了最优的FPE指标值和最优的订货量。我们进行敏感性分析并得出有关管理方面的结论。
