“…VZA, Farrell'in 1957 yılındaki çalışması temel alınarak ilk kez Charnes, Cooper ve Rhodes tarafından kullanılmıştır. Yöntem birden fazla çıktı üretebilmek için birden fazla girdi kullanan karar verme birimlerinin göreceli performansını ölçmek için kullanılan bir matematiksel programlama yaklaşımıdır (Paradi vd., 2011: 100;Joro and Korhonen, 2015: 2;Shamsijamkhaneh, 2018). Bu yaklaşım, karar verme birimlerinin girdileri ve çıktıları temelinde, verimli üretim sınırlarının oluşturulmasına izin veren doğrusal programlamaya dayalı parametrik olmayan bir tekniktir (Senante vd., 2018: 8432).…”

In this study, it is aimed to measure the activities of 17 firms which are registered in BİST (Borsa İstanbul) by Data Envelopment Analysis (DEA) and to determine how Malmquist Total Factor Productivity (MTFP) index and firms' efficiency change over the years. For this purpose, analyzes have been made by taking into account the data obtained from the financial statements and balance sheets for the years 2013-2017. In the analyzes, two output variables, namely current ratio, acid-test ratio, leverage ratio, financing rate, stock turnover rate and active turnover rate, six input variables and total asset profitability and profitability of sales were used.

“…By relaxing the constraints corresponding to intermediate measures the discriminating power of the model was enhanced. Shamsijamkhaneh et al (2018) proposed an approach in which the intermediate measures are classified into input or output type and the continuity of linking activities are kept simultaneously. Based on their approach they proposed two models to study on direct and indirect effect of inefficiency arising from intermediate measure in efficiency measurement.…”

This research aims to provide an innovative framework for evaluating airline performance through the networking of decision-making units (DMUs) and neutrosophic data. As a consequence, we propose a comprehensive methodology for assessing the efficiency of these decision-making units. Network data envelopment analysis (DEA) models deal with measurements of relative efficiency of DMUs when the insight of their internal structures is available. In network models, sub-processes are connected by links or intermediate products. Links have the dual role of output from one division or sub-process and input to another one. Therefore, improving the efficiency score of one division by increasing its output may reduce the score of another division because of increasing its input. To address this conflict, we proposed a new approach in Slack-Based Measure (SBM) framework and neutrosophic logic, which provide deeper insights regarding the sources of inefficiency. Our approach is a new network model, in which the intermediate products are classified into two groups of “input-type”, and “output-type” that their excesses and shortfalls directly concern with the objective function. The results of the illustrated case and analysis show that the constructed model may successfully produce performance assessments. By taking into account the number of slacks or surpluses of these products in the objective function, the proposed model gives analysts and managers a more accurate assessment of network structure efficiency. In this paper, we present a new model in the field of network data envelopment analysis with SBM approach in a neutrosphonic environment, in which for the first time the nature of intermediate products in terms of input or output is investigated. Also, the proposed framework is the first attempt to performance evaluation in neutrosophic network DEA.

A novel network DEA-R model for evaluating hospital services supply chain performance

et al. 2020

Assessing the efficiency of a supply chain (SC) is of great importance for managers and policy makers. For this aim, we propose a network data envelopment analysis (NDEA) model to reflect the internal structure of networks in efficiency evaluation. For many of the real-world performance evaluation problems, data of inputs and outputs are available, and their ratio conveys important messages to managers. However, conventional data envelopment analysis (DEA) models are no longer able to deal with ratio data. This paper aims to extend the NDEA models with the ratio data (NDEA-R) to evaluate the performance of SCs. Therefore, given the internal structure of a supply chain, relationships among different divisions of an SC are determined under two assumptions of free-links and fixed-links. Applicability of the proposed models is illustrated by evaluating supply chain of 19 hospitals in Iran over 6 months. By performing sensitivity analysis, we find out that the overall efficiency score of decision-making units (DMUs) under the fixed link assumption is greater than or equal to the overall efficiency of DMUs under free link assumption. Our proposed model overcomes the underestimation of efficiency and pseudo-inefficiency scores.
