introduction: the major target of this paper shows effect of selected decision variables in the steam system foroptimization of thermal combined cycle power plant.material and method: exergoeconomic, and other similar terms used to imply the combined thermodynamicand economic analysis of energy systems, which helps to increase the efficiency of a plant without jeopardizingits economic viability...

in some data envelopment analysis (dea) applications, some inputs of dmus have negative values with positive cost. this paper generalizes the global cost malmquist productivity index to compare the productivity of dierent dmus with negative inputs in any two periods of times under variable returns to scale (vrs) technology, and then the generalized index is decomposed to several components. th...

conclusions the results confirmed that the total costs for non-alcoholic fatty liver among the iranian adult urban population alone exceeded 1 billion ppp$ per year. these costs can be saved or reduced by effective disease management and early prevention. objectives this study aims to estimate the diagnosis and treatment costs of non-alcoholic fatty liver. patients and methods this cross-sectio...

medicines constitute a substantial proportion of out-of-pocket (oop) expenses in indian households. in order to address this issue, the government of india launched the jan aushadhi (medicine for the masses) scheme (jas) to provide cheap generic medicines to the patients (http://janaushadhi.gov.in/about_jan_aushadhi.html). these medicines are provided through the jan aushadhi stores established...

In the conventional data envelopment analysis (DEA), it is assumed that all decision making units (DMUs) using the same input and output measures, means that DMUs are homogeneous. In some settings, however, this usual assumption of DEA might be violated. A related problem is the problem of textit{missing} textit{data} where a DMU produces a certain output or consumes a certain input but the val...

The main goal of the paper is a consideration of cost efficiency evaluation models related to some supply chain when dealing with imprecise data. Data envelopment analysis (DEA) method is a non-parametric mathematical programming approach to assess the performance. This method is proposed for deterministic data and it can be generalized to inaccurate data, while considering real world applicati...

In multi-division organizations, goal congruence between different divisions and top management is critical to the success of management. In this paper, drawing upon a nonparametric framework to model production technology, we derive a necessary and sufficient condition for a firm with multiple divisions to be goal-congruent, and then extend it to a goal congruence testing measure, which coinci...

A partial occlusion of one or more of the coronary arteries due to atherosclerosis leads to an insufficient supply of blood to the myocardium and as a result to the reduction of its functioning (myocardial ischemia). A total occlusion blocks the blood supply completely, which generally leads to starvation of myocardial tissue (myocardial infarction). Magnetic resonance imaging (MRI) has proven ...

This paper describes the process of developing an approach to evaluating the cost-efficiency of Finnish electricity distribution companies for regulation purposes. The process consisted of three main stages 1) describing of the problem and exploring the key factors, 2) finding measurable quantities for the most essential factors, and 3) selecting the final model to be used in the regulation. Th...

Background There is limited evidence detailing the cost-effectiveness of psoriasis treatments in the Asian region. Therefore, this study is aimed to evaluate the cost-effectiveness of 3 psoriasis treatments tailored for moderate to severe psoriasis, namely topical and phototherapy (TP), topical and systemic (TS), and topical and biologic (TB) regimens, respectively. Me...
