Today, managers are seeking more efficient use of resources and manufacturing the products with the highest efficiencies. Data Envelopment Analysis (DEA) is a powerful tool for evaluating the efficiency of the decision making units. So far, in most studies, Data Envelopment Analysis has been applied to evaluate the efficiency of the separate organizations. However, in this study, DEA has been a...

Background and Aim: Quality management, as an organizational strategy, helps enhance hospital effectiveness and efficiency. This study aimed to examine the effect of a quality management model on the efficiency of the respiratory intensive care unit in Labafijejad Hospital, Tehran in 2013-14. Materials and Methods: This was a participatory action research conducted  in  the respiratory intens...

In traditional data envelopment analysis (DEA) the uncertainty of inputs and outputs is not considered when evaluating the performance of a unit. In other words, effects of uncertainty on optimality and feasibility of models are ignored. This paper introduces a new model for measuring the efficiency of decision making units (DMUs) having interval inputs and outputs. The proposed model is based ...

It is very necessary to consider the uncertainty in the data and how to deal with it when performance measurement using data envelopment analysis. Because a little deviation in the data can lead to a significant change in the performance results. However, in the real world and in many cases, the data is uncertain. Interval data envelopment analysis is one of the most widely used approaches to d...

OBJECTIVE The purpose of this study was to evaluate the following: 1) the effects of continuous exercise training and interval exercise training on the end-tidal carbon dioxide pressure (PETCO2) response during a graded exercise test in patients with coronary artery disease; and 2) the effects of exercise training modalities on the association between PETCO2 at the ventilatory anaerobic thresho...

‎In this paper, we present a two-stage model for ranking of decision making units (DMUs) using interval analytic hierarchy process (AHP). Since the efficiency score of unity is assigned to the efficient units, we evaluate the efficiency of each DMU by basic DEA models and calculate the weights of the criteria using proposed model. In the first stage, the proposed model evaluates decision making...

Data Envelopment Analysis (DEA) is a technique for measuring the efficiency of a set of Decision Making Units (DMUs) with common data, but in general it is not practical. This paper presents a framework where DEA is used to measure overall profit efficiency with fuzzy data. Specifically, it is shown that as the inputs, outputs and price vectors are fuzzy numbers, the DMUs cannot be easily evalu...
