Huang [ Journal of Statistics and Management Systems, Vol. 6 (2003), No. 2, pp. 171-180 ] studied the EOQ (Economic Order Quantity) and EPQ (Economic Production Quantity) models with backlogging and defective items using the algebraic approach. He assumed 100% inspection policy and the known proportion of defective items was removed prior to storage or use after the screening process. In this p...

This paper formulates an integrated inventory model that allows Stackelberg game policy for optimizing joint total cost of a vendor and buyer system. After receiving the lot, the buyer commences an inspection process to determine the defective items. All defective items the buyer sends to vendor during the receiving of the next lot. Due to increasing number of shipments fixed and variable trans...

This paper demonstrates the use of Bayesian methods in Acceptance Sampling for items which are categorized according to their attributes as defective or non defective, i.e binary (0-1) data. The main thrust of the paper is to account for the possibility of dependence among the items of a sample. An attempt has been made to incorporate the dependence structure in the acceptance sampling scheme. ...

The Economic Production Quantity (EPQ) model is often used in the manufacturing sector to assist firms in determining the optimal production lot size that minimizes overall production-inventory costs. There are some assumptions in the EPQ model that restrict this model for real-world applications. Some of these assumptions are (1) infinite space of warehouse, (2) all of the pr...

A study of two warehouse inventory systems with a production unit is developed in this article some constraints which are practical applicability to optimize the total cycle and its cost. evolves three different states retain quality prolong lifetime: state producing items, reworking identified defective being idle. It processes items up certain time point. The screening process starts immediat...

Efficiency in the supply chain can be established by integrating supplier-retailer inventory policy. This article proposes integrated model between under stochastic demand. aims to determine optimal review period and calculate total cost, including some defective items, backorder price discounts, losing flexibility costs. We assume that retailer order 'n' times for every 'm' shipment from suppl...

This paper deals with an economic order quantity model where demand is stock dependent. Items received are not of perfect quality and each lot received contains percentage defective imperfect quality items, which follow a probability distribution. Two cases are considered. 1) Imperfect quality items are held in stock and sold in a single batch after a 100 percent screening process. 2) A hundred...

Recycling of products has a great impact on contemporary sustainable business strategies. In this study, recycling process in production-inventory model for an imperfect production system with fixed ratio recyclable defective is introduced. The piecewise constant demand rates the non-defective items are considered under run-time, off-time positive stock, and shortages varying conditions. Based ...
