An order-level inventory model for deteriorating items having constant deterioration rate was studied by Shah and Jaiswal (1977).
Srivastava and Gupta (2007) studied an EOQ model for deteriorating items with constant deterioration rate, both the constant and time-dependent demand rate and no-shortages.
The inventory models for deteriorating items with constant deterioration rate and exponential demand rate are established by Hollter and Mak (1983) and Ouyang et al.
The model can be extended in several ways, for example, we may consider the deteriorating items with a constant deterioration rate.
Accordingly, Hsu et al. (2010) first investigated the impact of deteriorating inventory with a constant deterioration rate, time-dependent partial backorders and preservation technology investment.
Taleizadeh and Nematollahi (2014) investigated an EOQ model for constant demand for deteriorating items with financial considerations.
Cultural heritage objects in situ, on display or in storage are in constant danger of deteriorating due to aggressive chemical species in the indoor air.
Polymer-based PM is an alternative to ceramic crystals but they have lower piezoelectric coupling constants which deteriorates quickly at high temperature.
(2011) discussed an order-level inventory model for a deteriorating item with time-dependent quadratic demand rate and constant deterioration rate.
The results in Table 2 show that as age, brachial SBP, and cfPWV increased, the spring constant significantly decreased, indicating deteriorating elasticity in the artery.
