energy, due to its increasing usage in various broad areas has been maintained as a vital factor in economic growth and development of societies. meanwhile, natural gas is considered as one of the most important energy sources. therefore, the efficiency and the productivity of the gas companies are crucial to be assessed. numerous examples from industrial multistage processes including internal...

in many european states such as spain and italy there has been a significant growth of organic utilizable surface as a consequence of both a change in the model of agricultural production and also in order to satisfy arising demand of organic food. the purpose of this research was to investigate the level of technical, allocative and economic efficiency in italian olive farms with two different...

In this study, the window network data envelopment analysis (WNDEA) model will be proposed, that is capable to be used in the presence of panel data. Additionally, the proposed model is applied to evaluate the dynamic efficiency of 5 investment companies in Tehran stock exchange during the period from 2013 to 2017.

Ecological efficiency (EE) provides much reference for formulating appropriate regional economic, social and environmental policies to promote sustainable development. Interactive subsystems of economy, society environment within EE system have been considered in this paper. By innovatively integrating the merits two advanced economic research methods (global super network data envelopment anal...

one of the effective methods for improving the efficiency of an organization is benchmarking against successful organizations. not only benchmarking could be a technique for identifying problems but also it greatly helps managers in relations of the design of processes. among strategic and infrastructure industries in each country, the electricity industry is one of the most important and criti...

for efficiency evaluation of some of the decision making units that have uncertain information, rough data envelopment analysis technique is used, which is derived from rough set theorem and data envelopment analysis (dea). in some situations rough data alter nonradially. to this end, this paper proposes additive rough–dea model and illustrates the proposed model by a numerical example.
