Recently, much emphasis has given to study the control and maintenance of production inventories of the deteriorating items. Rework is one of the main issues in reverse logistic and green supply chain, since it can reduce production cost and the environmental problem. Many researchers have focused on developing rework model, but few of them have developed model for deteriorating items. Due to t...
Economic production quantity (EPQ) inventory model for trended demand has been analyzed with rework facility and stochastic preventive machine time. Due to the complexity of the model, search method is proposed to determine the best optimal solution. A numerical example and sensitivity analysis are carried out to validate the proposed model. From the sensitivity analysis, it is observed that th...
In this paper we consider an imperfect production system which produces good and defective items and assume that defective items can be reworked. Due to the nature of rework process we do not restrict the rework rate to be equal to normal production rate or constant and assume that it is a random variable with an arbitrary distribution function. We also assume as it is true in most real world s...
this paper investigates an epq model with the increasing demand and demand dependent production rate involving the trade credit financing policy, which is seldom reported in the literatures. the model considers the manufacturer was offered by the supplier a delayed payment time. it is assumed that the demand is a linear increasing function of the time and the production rate is proportional to ...
EPQ model; Replenishment lot size; Multiple deliveries; Random defective items; Production; Rework; Scrap items. Abstract This paper derives the optimal replenishment lot size and shipment policy for an Economic Production Quantity (EPQ) model with multiple deliveries and rework of random defective items. The classic EPQmodel assumes a continuous inventory issuing policy for satisfying demand a...
A two-warehouse inventory model with deteriorating items and rework process time varying demand rate is presented. The Last-In-First-Out (LIFO) First-In-First-Out (FIFO) policies are considered the assumption that holding cost higher in rented warehouse (RW) compared to owned (OW). aim of proposed determine optimum values a production cycle will minimise total relevant cost, TRC*. We have utili...
In this paper, a production inventory model is developed for the business enterprise which consists of three wings. The first wing is for manufacturing new items, the second wing is for collecting the returned items, while third wing is for remanufacturing the returned item. In this model we consider the fact that the storage item is deteriorated during storage periods and salvage value is inco...
This paper derives the optimal production-shipment policy for a vendor-buyer integrated system with rework process and a cost lessening product delivery plan. The objective is to derive the optimal production lot size and number of deliveries that minimizes total costs for the proposed vendor-buyer integrated system. This paper extends the work of Chiu et al. [Joint determination of the product...
