<p style='text-indent:20px;'>This paper presents a mathematical framework to derive an inventory model for time, reliability, and advertisement dependent demand. This considers the demand rate is high initially, then reduces later stage, which reflects situation related cash in hand. The uncertain deterioration of product through Uniform, Triangular, Double Triangular probability distribu...

A single-item economic production model is developed in which inventory is depleted not only due to demand but also by deterioration. The rate of deterioration is taken to be time dependent, and the time to deterioration is assumed to follow a two-parameter Weibull distribution. The Weibull distribution, which is capable of representing constant, increasing, and decreasing rates of deterioratio...

the term ‘deteriorated texture’ gives all experts as well as ordinary people almost the sameimpression. despite common points in images, the differences put iran cities in different categories based on deteriorated textures. this classification not only has negative effect on the audience from mental point of view but causes various problems for the experts in determining interference method. f...

This study models a joint pricing, inventory, and preservation decision-making problem for deteriorating items subject to stochastic demand and promotional effort. The generalized price-dependent stochastic demand, time proportional deterioration, and partial backlogging rates are used to model the inventory system. The objective is to find the optimal pricing, replenishment, and preservation t...

a r t i c l e i n f o The optimal replenishment policy for an economic production quantity (EPQ)-based inventory model with nonconforming items and breakdown is presented. A real-life production system inevitably generates nonconforming items and has equipment breakdowns owing to process deterioration or other uncontrollable factors. This study addressed these issues in an EPQ-based system to o...

Abstract In this paper a deterministic supply chain inventory model has been developed for deteriorating items having a ramp type demand with the effects of inflation with two-storage facilities and Economic Load Dispatch Problem Using Genetic Algorithm.. The owned warehouse (OW) has a fixed capacity of W units; the rented warehouse (RW) has unlimited capacity. Here, we assumed that the invento...

A “phantom stockout” is a retail stockout phenomenon caused either by inventory shrinkage or by shelf execution failure. Unlike the conventional stockout which can be corrected by inventory replenishment, a phantom stockout persists and requires human interventions. In this paper, we propose two partially-observable Markov decision models: one for the shrinkage problem and the other for the she...

Classical spare parts inventory models assume that the same vintage of technology will be utilized throughout the planning horizon. However, replacement often occurs in the form of a new technology. A consequence of such replacements is the rendering of existing spare parts inventories obsolete and the necessity to purchase a new set. This paper aims to study the impact of spare parts inventory...

proper inventory control policy and the optimal price for the items has always been one of the main topics of scientific research and industry. on the other hand, there are many products in the market witch are classified as deteriorating items. therefore the problem of determining optimal price and optimal inventory policy for this type of items is very important. in this paper a 3 echelon sup...
