Effect of learning and salvage worth on an inventory model for deteriorating items with inventory-dependent demand rate and partial backlogging with capability constraints

Abstract

In this paper, an inventory model is built with inventory-dependent demand rate and twowarehouses in which demand rate is a polynomial of current inventory level. Moreover, it is typically the case in which the value of system engaged in repetitive operations decreases. Thus, the impact of learning from repetitive method cannot be unnoticed while developing the inventory model with two-level storage. Here, we tend to assume that the capability of the own warehouse, holding value of own and rented warehouse is partly constant and partly decreasing in every cycle, merit to learning impact. Impact of salvage worth is additionally thought of for the deteriorating things. Additionally, we tend to give shortages and assume that the backlogging demand rate depends on the period of the stock-out. The solution is found with the help of some numerical examples. Sensitivity analysis in relation to numerous parameters is also shown.

Pricing model for instantaneous deteriorating items with partial backlogging and different demand rates

“…They also allowed shortages partially with back order rate in fraction form. Kumar and Kumar (2016) studied the salvage worth and learning by considering partial shortages, Tripathi and Kaur (2017) considered time-shortages, which is non-increasing and interestingly since they assumed deterioration as time dependent, which is non-decreasing. Apart, Saha and Sen (2017) studied deterioration as probabilistic with backlogging and demand as negative exponential.…”

A multi-product inventory management model in a three-level supply chain with multiple members at each level

“…Below is a brief overview of some related studies conducted on inventory management models in supply chains with more than two levels, and supply chains with more than a few members per level. Kumar and Kumar (2016) investigated the effect of learning and salvage worth on an inventory model for deteriorating items with inventory-dependent demand rate and partial backlogging with capability constraints. Mashud et al (2018) studied a non-instantaneous inventory model having various deterioration rates with stock and price dependent demand under partially backlogged shortages.…”

The Role of Items Quantity Constraint to Control the Optimal Economic Order Quantity

“…Rezaei (2014) proposed a general mathematical model, which was used for various types of growing products, followed by a particular mathematical model for specific types of poultry. Kumar and Singh (2015) built an inventory model with two depots and a dependent demand rate in which demand rate was a polynomial of current inventory level. Furthermore, they assumed the value of system engaged in repetitive operations decreases.…”
