One way to rank DMUs in DEA is the cross efficiency method. In this method, the efficiencyof each DMU is calculated by other DMUs optimum weights, which makes the ranking moreacceptable for managers. Existing alternative optimum weights in cross efficiency methodlead to several ranks for DMUs. Several secondary goals have introduced to avoid thisproblem, till now. In this paper, a new model is ...
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...
In this article, we analyzed the efficiency of food and beverage companies that were accepted in stock market, using a nonlinear model. This model eliminates the weak points of base Data Envelopment Models in high computing, lack of integration and too many numbers of zero weights. Taking into account that in this study we developed the base Data Envelopment Analysis model, the research method...
Body weight (BW) records (n=11,659) of 4961 Kurdi sheep from 215 sires and 2085 dams were used to estimate the additive genetic, direct and maternal permanent environmental effects on growth from 1 to 300 days of age. The data were collected from 1993 to 2015 at a breeding station in North Khorasan province; Iran. Genetic parameters for growth traits were estimated using random regression test-...
Delineation of potential sites for groundwater artificial recharge is an important and challenging task. The purpose of this research is to develop a new data-driven fuzzy approach to model potential sites for groundwater artificial recharge. To achieve this end, the efficient criteria of a proper site for groundwater artificial recharge were first recognized and presented as a conceptual model...
The weighted average is an efficient way to address conflicting evidence combination in the Dempster-Shafer theory. However, it open issue how determine weights reasonably. Although many traditional solutions based on distance or entropy have been put forward, are determined with a single aspect, and no comprehensive consideration of other useful information affects weights. Thus, does not ensu...
in models of data envelopment analysis (dea), an optimal set of weights is generally assumed to represent the assessed decision making unit (dmu) in the best light in comparison to all the other dmus, and so there is an optimal set of weights corresponding to each dmu. the present paper, proposes a three stage method to determine one common set of weights for decision making units. then, we use...
Knowledge-and data-driven approaches are two major methods used to integrate various evidential maps for mineral prospectivity mapping (MPM). Geological maps, geochemical samples and data from known gold deposits were collected in the western Junggar area, Xinjiang Province. The geological and a spatial database for geological and mineral occurrences were constructed for the studied region. A w...
groundwater resource is a very important water resource that has stable temperature, clear, tidy and confident. in recent years, population growth, industrialize and need to food and water, have exposed the groundwater resource on the risk. reduction of water resources is a main problem in throughout the world. in this research groundwater potential mapping was obtained in norabad plain, lorest...
In this paper an approach in data envelopment analysis dealing with evaluation of non – zero slacks was propounded. This approach intends that weight of inefficient and weak efficient points that have been evaluated as zero weight, be considered as positive weight, and also in this approach, the pareto efficiency evaluates the picture of this point. In this approach positive weights in the i...
