We study a finite capacity Markovian queuing system with two heterogeneous servers, reverse balking, and reneging. The stationary system size probabilities are obtained by using iterative method. The measures of performance like expected system size, the average rate of reverse balking, and the average rate of reneging are obtained. Finally,...

This paper provides a developed mathematical model to derive the optimal integrated lot sizing in a multi-level supply chain with imperfect quality products. The developed mathematical model has a bi-objective function, with conflicting goals, minimizing the chain inventory costs and maximizing the chain total profit aided to find optimum policy...

The planning activity relative to physical items, environment, and services that adapts to optimize social, economic, and ecological impact is the target of sustainable design. Quality Function Deployment (QFD) achieves product design by choosing and defining factors that can be qualitatively argued. The aim of design is to match needs...

Traditional EOQ models are assumed that it is upstream full trade credit and down steam partial trade credit. In most business transactions, this assumption is debatable. In this note, this paper establishes a new EOQ model under two levels of trade credit, in which the supplier offers to the retailer...

In an industrial set-up, conditions of orthogonality and optimality of a statistical experimental design often get violated. This paper attempts to find an optimal design which performs uniformly better with respect to multi-design-optimality criteria. Initially, using non-dominated
sorting genetic algorithm (NSGA-II) with single D-optimality criterion, a near-optimal design is searched for...

This paper aims to estimate the stress-strength reliability parameter R = P(Y < X) using progressive type-ll censored data, when X and Y are two independent inverse Weibull variates with different scale parameters but having common shape parameter. The maximum likelihood estimator (MLE) and approximate maximum likelihood estimator (AMLE) of...

This article focuses on an imperfect production inventory model with production system reliability under two layer supply chain management. Here, we consider the production system may be shift from in-control state to an out-of-control after a time which is a random variable. A development cost is incurred to improve the...

Recently, a varied L ranked set sampling (VLRSS) scheme has been introduced in the literature for estimating the population mean. The VLRSS scheme is a cost-efficient alternative to the classical ranked-set sampling (RSS) and median RSS (MRSS) schemes. In this paper, we construct a new cumulative sum (CUSUM) control chart...

Cellular manufacturing is a practical aspect of grouping technology in where similar parts and dissimilar machines are grouped into cells to exploit the cost-effectiveness of mass production and flexibility of job shop manufacturing. In this research, a Genetic Algorithm (GA) approach is developed to solve the grouping problem in cellular...
