The main difference between conventional data envelopment analysis (DEA) and network (NDEA) lies in the internal structure of a decision-making unit (DMU). Most existing NDEA methodologies neglect to address issue incorporating influence intermediate, directly objective function. To overcome this shortcoming, paper, based on feature SBM model, researcher is setting an NSBM model for evaluating ...
due to extraordinary large amount of information and daily sharp increasing claimant for ui benefits and because of serious constraint of financial barriers, the importance of handling fraud detection in order to discover, control and predict fraudulent claims is inevitable. we use the most appropriate data mining methodology, methods, techniques and tools to extract knowledge or insights from ...
in the data envelopment analysis (dea) the efficiency of the units can be obtained by identifying the degree of the importance of the criteria (inputs-outputs).in dea basic models, challenges are zero and unequal weights of the criteria when decision- making units are evaluated. one of the strategies applied to deal with these problems is using common weights of the each input...
This paper presents a new robust two-stage Data Envelopment Analysis (DEA) for efficiency evaluation of the electricity power production and distribution companies. DEA has been widely used for benchmarking the electricity companies. Traditional studies in DEA consider systems as a whole when measuring the efficiency, ignoring the operation of individual processes within a system. To tackle thi...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Network data envelopment analysis (NDEA) is an extension of standard DEA that models the efficiency assessment decision-making units (DMUs) by considering their internal structure. While in DEA, DMU regarded as a single process, NDEA, viewed network interconnected sub-processes (stages, divisions), where flow intermediate products (measures) essential assessment. In prevalent conventional metho...
The increasing use of information technology (IT) in supply chain management and logistics is connected to corporate advantages enhanced competitiveness provided by enterprise resource planning systems warehouse systems. One downside advancing digitalization an dependence on IT the negative effects disruption impacts firm performance, measured efficiency, e.g., with data envelopment analysis (D...
the present study is an attempt towards remodeling cost, revenue and profit relationship within the network process. the previous models of data envelopment analysis (dea) have been too general in their scope and focused on the input and the output within a black box system, therefore they have not been able to measure various phases simultaneously within a network system. by using these models...
