TLDR
How much discount on selling price may be given during deterioration to maximize the profit per unit time and whether a pre-deterioration discount affects the unit profit or not is investigated.Abstract:
A single item economic order quantity model is considered in which the demand is stock dependent. After a certain time the product starts to deteriorate and due to visualization effect and other aspects of deterioration the demand becomes constant. In that situation a discount on selling price provides significant increment in demand rate. In this paper we investigate how much discount on selling price may be given during deterioration to maximize the profit per unit time and whether a pre-deterioration discount affects the unit profit or not. A mathematical model is developed incorporating both pre- and post deterioration discounts on unit selling price, where analytical results reveal some important characteristics of discount structure. A numerical example is presented and sensitivity analysis of the model is carried out.read more

Subrata Saha,Suresh Kumar Goyal +1 more
TL;DR: In this paper, three unlike coordinating contracts namely (i) joint rebate contract (ii) wholesale price discount contract and (iii) cost sharing contract are proposed for two echelon supply chain coordination perspective under stock and price induced demand.

Disposal cost sharing and bargaining for coordination and profit division in a three-echelon supply chain
TL;DR: In this paper, the authors focus on coordination and profit division in a manufacturer-distributer-retailer supply chain, where the manufacturer supplies a perishable product to the retailer through the distributer in a single lot.

An application of interval differential equation on a production inventory model with interval‐valued demand via center‐radius optimization technique and particle swarm optimization
TL;DR: A food production model with preservation technology and credit‐linked demand under default risk of capital in uncertain environment is developed with the help of parametric approach and interval mathematics to justify the validity of the proposed model.

Optimal pricing and lot-sizing for perishable inventory with price and time dependent ramp-type demand
TL;DR: A dynamic pre- and post-deterioration cumulative discount policy to enhance inventory depletion rate resulting low volume of deterioration cost, holding cost and hence higher profit is proposed.

A Simple Inventory Replenishment Decision Rule for a Linear Trend in Demand
TL;DR: In this paper, the authors consider the situation of a deterministic demand pattern having a linear trend and select the timing and sizes of replenishments so as to keep the total of replenishment and carrying costs as low as possible.

TL;DR: A comprehensive overview of the literature on inventory control models in which the demand rate of an item is a function of the initial inventory level and those in which it is dependent on the instantaneous inventory level is presented.

A deterministic inventory model for deteriorating items with stock-dependent demand rate
TL;DR: In this article, a deterministic inventory model is developed by assuming that the demand rate is stock-dependent and the items deteriorate at a constant rate, and the expression for the average net profit π over one production run is derived and its optimization with respect to the decision variables Q (initial stock) and T (duration of a production cycle) is carried out.
