Strategies in project assortment and prioritization directly influence organizational production and cost-effectiveness. Due to dearth of funding and nominal technology with improper judgments of expert’s, selection of optimal project portfolio can be viewed as a risk based decision making problem considering various risk factors. Recently, fuzzy set theory is applied for modeling real world problems...
In many situations, a common revenue or benefit must be distributed amongst a set of beneficiary decision making units (DMUs) with imprecise data represented by fuzzy or stochastic data. A fair revenue distribution can certainly increase the motivation of DMUs for improving their performances. The share of each DMU must be determined according to its eligibility. To access a fair distribution, we...
In this paper properties of generalized cone locally (strictly) connected functions are studied. The concepts of cone locally (strictly) Pseudo connected and cone locally (naturally) quasi connected functions are introduced. Various interrelations between these function are discussed with the help of an example. Necessary optimality conditions are obtained for an approximate weak quasi efficient solution...
This research intends to empirically examine within the ambit of Indian consumer electronics market the relationship between product prices and select product, market, and consumer related facets. Product distinctiveness (function of product commonality), consumer choice probabilities and numeral ratings of consumer reviews associated with product offerings within a market segment are considered the...
In the past decade, the explosive growth of social media has led to the emergence of a wide variety of information sources that can significantly impact individual level decision making processes. This has resulted in an increasing availability of unstructured textual data and automated evaluation of opinions, attitudes, and emotions has been accepted as an indispensable analytical tool in diverse...
In recent years, business schools face a common problem of selecting quality students for their Master of Business Administration (MBA) programs so that the target placement percentage is achieved. Selecting a wrong student may increase the number of unplaced students. Also, more the number of unplaced students more is the negative impact on the institute’s reputation. Business school authorities...
Industries across the world today are looking for cost effective solutions to reduce waste and curb the carbon emission, due to heightened awareness about ecological responsibility coupled with stringent government regulation and legislations, through operational adjustments in manufacturing/remanufacturing and collection (used products) policy. This paper presents a production, remanufacture and...
In the present paper, the notion of geodesic E-preinvex function and geodesic semi E-preinvex function are introduced on Riemannian manifold. Moreover, several properties, results and relations are studied within aforesaid functions. An example is also constructed to illustrate the definition of geodesic E-preinvex function. In addition, we have studied the optimality results with the help of geodesic...
This article considers an integrated inventory model that deals with one manufacturer and one retailer. The manufacturer provides warranty period for the finished product to ensure product reliability. Also, the manufacturer gives the opportunity to take the facility of delay payment to the retailer. The main objective of this article is to analyze the effect of the credit period offered by the manufacturer...
Summer Olympic games in Rio 2016 were the biggest and the most important sport event in 2016. Athletes’ performance at Olympics is always of a high interest and serve as a basis for various parametric and non-parametric analyses. In this article, we construct data envelopment analysis model to analyze countries’ performance in Summer Olympic games in Rio 2016. The traditional model structure is based...
Selecting the appropriate plant location is among the most important decisions a company will ever make. The present study examines the criteria affecting investors’ decisions concerning the location of their plants. Its main purpose is to incorporate the most significant measures used in the international literature and develop a new decision model (research model). The proposed research model was...
By considering an M|Er|1 queueing model, the maximum likelihood and consistent estimators of arrival and service parameters are obtained by observing interarrival and service times in the system. Bayes estimators of the parameters both under squared error loss function (SELF) and entropy loss function along with minimum posterior risk and minimum Bayes risk associated with the estimators under SELF...
The concepts of fuzziness and parametric analysis are of importance to treat uncertainty in mathematical model and may offer certain more viewpoints. The basic notions of the parametric study in nonlinear programming problem are presented by Osman (Aplikace matematiky 22(5):318–332, 1977; Aplikace matematiky 22(5):333–348, 1977). In general, a parametric programming problem is not easy to be solved...
In this paper we addressed supply chain network (SCN) as bi-level programming problem in which the primary objective is to determine optimal order allocation of products where the customer’s demands and supply for the products are fuzzy. In the proposed SCN model, we suppose that the first level (leader) and second level (follower) operate two separate groups of SCN. The leader, who moves first, determines...
The conventional data envelopment analysis (DEA) models make an assumption of non-negativity in the inputs and outputs data of the decision making units (DMUs) under analysis. In this paper, we present a non-radial measure of efficiency of DMUs by establishing a multi-period additive DEA model taking into consideration both desirable and undesirable inputs and outputs with positive and non-positive...
Modern world is a competitive world. To survive in this world, every industry must achieve competitiveness. So, it has become the most important task for them to select the best Advanced Manufacturing Technology (AMT). The process involves both quantitative and qualitative factors. The aim of this paper is to solve the problem by Fuzzy TOPSIS method. According to the method of TOPSIS, a closeness...
The objective of this study is to present a systematic literature review in the context of bank efficiency and productivity. It focuses on the recent developments related to empirical methodological advances and new dimensions added to the ever-growing field of bank performance analysis. Selected research papers were coded in terms of their key objectives and were segregated into 11 themes—Branch,...
Sustainable freight transportation (SFT) and cold-chain for perishable food products are the two most prominent areas where research is tremendously growing with increasing number of publications in various reputed journals. The area of SFT for perishable products is still in the nascent stage and not much explored. There are a number of published articles in the cold chain, but only a few have addressed...
This paper studies an M/M/1 queue with single, multiple working vacations and customers’ variant impatient behavior. During working vacations, the arriving customers are served with slower service rate than the service rate of non-vacation period. An arriving customer, during working vacation, finds the system empty and gets his service immediately, does not become impatient. The only customers who...
