TL;DR: In this article, the authors extended the traditional economic production quantity model by accounting for imperfect quality items when using the EPQ/EOQ formulae, and considered the issue that poor-quality items are sold as a single batch by the end of the 100% screening process.

TL;DR: In this article, the effect of imperfect quality items on the finite production model was studied. And the optimal operating policy that minimizes the total inventory cost per unit time was derived where shortages are allowed and backordered.
Abstract: This paper studies the effect of imperfect quality items on the finite production model. When production stops, defective items are assumed to be reworked at a constant rate. The percentage of imperfect quality items is considered to be a random variable with a known probability density function. The demand for the initial perfect items and the perfect items being reworked is continuous during the cycle. The optimal operating policy that minimizes the total inventory cost per unit time for the finite production model under the effect of imperfect quality is derived where shortages are allowed and backordered.

TL;DR: In this article, the authors examined the continuous review inventory model under permissible delays in payments, where a retailer has the option of either paying for the goods immediately upon the receipt of the order or delaying the payment till the next replenishment order, where interest will be charged over the delay period.

TL;DR: The optimum just-in-time buffer level is determined by trading off the holding cost per unit per unit of time and the shortage cost perunit of time such that their sum is minimum.

TL;DR: In this paper, a finite production inventory model was formulated taking into consideration the effect of machine unavailability on optimum production quantity and minimum total inventory system cost, which is a natural phenomenon that the performance of a person engaged in a repetitive task improves with time.

TL;DR: In this paper, a review of the literature on maintenance management and suggest possible gaps from the point of view of researchers and practitioners is presented, where important issues in maintenance management range from various optimization models, maintenance techniques, scheduling and information systems.
Abstract: Purpose – The purpose of this paper is to review the literature on maintenance management and suggest possible gaps from the point of view of researchers and practitionersDesign/methodology/approach – The paper systematically categorizes the published literature and then analyzes and reviews it methodicallyFindings – The paper finds that important issues in maintenance management range from various optimization models, maintenance techniques, scheduling, and information systems etc Within each category, gaps have been identified A new shift in maintenance paradigm is also highlightedPractical implications – Literature on classification of maintenance management has so far been very limited This paper reviews a large number of papers in this field and suggests a classification in to various areas and sub areas Subsequently, various emerging trends in the field of maintenance management are identified to help researchers specifying gaps in the literature and direct research efforts suitablyOriginali

TL;DR: In this article, an optimal inventory model for items with imperfect quality and shortage backordering is developed, in view of the fact that poor quality items do exist during production and are usually picked up during the screening process and are withdrawn from stock instantaneously.
Abstract: In this study, we develop an optimal inventory model for items with imperfect quality and shortage backordering. Such implicit assumption is reasonable in view of the fact that poor-quality items do exist during production. They are usually picked up during the screening process and are withdrawn from stock instantaneously. It is assumed that all customers are willing to wait for new supply when there is a shortage. The analysis shows that our model is a generalization of the models in current literatures. An algorithm and numerical analysis developed show that our model always results in better performance.
