Pricing and Ordering Decisions in a JELS-Model for Items with Imperfect Quality

2018
This paper presents a joint economic-lot-size (JELS) model for coordinated inventory replenishment decisions between buyer and vendor. The vendor’s production process is imperfect and produces a certain number of defective items with a known probability density function. The items are delivered to the buyer in equal-sized lots. The buyer faces a linear,

Imperfect Quality Item Inventory Models Considering Carbon Emissions

2019
Research on inventory models with environmental consideration has recently become a popular research stream. The amount of energy consumption and greenhouse gas emissions is influenced by inventory decisions such as delivery quantity and delivery frequencies. This chapter focuses on a supply chain system which contains a percentage of imperfect quality

Economic order quantity model with backorder for imperfect quality items

Proceedings. 2005 IEEE International Engineering Management Conference, 2005., 2005
In the classical inventory models, the issue of quality is ignored. However, in a real production environment, it can be observed that there are defective items being produced. These defective items must be rejected, repaired, reworked, or, if they have reached the customer, refunded, and hence, extra costs are incurred.

Economic order quantity model for items with imperfect quality with learning in inspection

International Journal of Production Economics, 2010
Abstract The economic order quantity (EOQ) model is the simplest and earliest inventory model in the literature. Its simple mathematics is attributed to its assumptions, which are rarely met.

Credit financing for deteriorating imperfect-quality items under inflationary conditions

International Journal of Services Operations and Informatics, 2011
In today’s technology-driven world, despite of efficient planning of manufacturing system and emergence of sophisticated production methods and control systems; the items produced have some fraction of defectives. However, these defective items can be removed from the lot through a screening process.

An EOQ model for imperfect quality items with multiple quality characteristic screening and shortage backordering

European J. of Industrial Engineering, 2015
In this paper, we propose an inventory model where items are inspected through multiple screening processes on varies quality characteristics before delivery to customers. Each screening process on a single quality characteristic has independent screening rate and defective percentage.

A Joint Replenishment Inventory Model for Imperfect Quality Items with Shortages

2015
An n items joint replenishment inventory problem is considered here, where the demand of each items are constant and deterministic. A joint replenishment is conducted periodically every T time intervals. However, all items may not be included in each replenishment. Item i is only included every ZiT time intervals.
