Abstract
A Two Warehouse Inventory Model for Perishable Items with Ramp Type Demand and Partial Backlogging
Highlights
Perishable or deteriorating items are those, which have finite or limited shelf life
When the demand becomes constant at = k1T =0.804 months, the rented warehouse (RW) is emptied at t1 =1.3765 months, after which demand is fulfilled from owned warehouse (OW), the inventory in OW lasts for t2 = kT = 6.063072 months of the
The RW is emptied in t1 =0.798188 months, after which demand is fulfilled from OW, where the demand becomes constant at = k1T =10.5 months, the inventory in OW lasts for t2 = kT = 10.57098 months of
Summary
Perishable or deteriorating items are those, which have finite or limited shelf life. Analyzed an inventory model for deteriorating items with ramp type demand and price discount under the effect of partial backlogging. Rong et al (2008) presented an optimization inventory policy for a deteriorating item with partially/fully backlogged shortages and price dependent demand under two-warehouse system. Singh et al (2018) proposed a two-warehouse inventory model in which demand rate varies exponentially with time and deterioration of items follows two-parameter Weibull distribution under the effect of inflation. Sharma and Singh (2013) proposed an inventory model for deteriorating items with partial backlogging considering stock and selling price dependent demand rate in fuzzy environment. Singh et al (2017) proposed a production inventory model for deteriorating items with time dependent demand rate and demand dependent production rate considering that shortages are allowed and partially backlogged.
