Selecting Energy Efficient Poultry Egg Producers: A Fuzzy Data Envelopment Analysis Approach
Authors
Abstract:
This study examined the energy use pattern of poultry for egg production farms of Iran and ranked the selected farmers using fuzzy data envelopment analysis (FDEA) from the viewpoint of energy efficiency. Since data used in our study were not measured precisely, fuzzy forms of them could help us to reach the ideal situations. Hence, the conventional data envelopment analysis (DEA) was remodeled using triangular fuzzy numbers and finally the resulted efficiency scores of decision making units (DMUs) were compared. Those with efficiency score of less than one were reported as inefficient units and they were also ranked by calculating an index. The results of this study indicated that from 40 poultry farms selected randomly, 33 of them were inefficient. FDEA was performed using α-cut approach and eleven α-levels (0 to 1 by 0.1) were examined. According to our results, the efficiency scores showed a decreasing trend as α- levels increasing to crisp situations. It is obvious that applying fuzzy data can show the real situation more accurately. Based on the results of this study, decision makers and farmers can improve their attitudes against energy use and applying well established practices. To achieve this, firstly, we should distinguish efficient units from inefficient ones. Keywords: Energy Efficiency, Fuzzy Data Envelopment Analysis, Feed Intake, Poultry, Egg Production.

Technical Efficiency of Poultry Egg Production in Ogun State: A Data Envelopment Analysis (DEA) Approach
The study examines the technical efficiency of poultry egg production in Ogun state using Data Envelopment Analysis (DEA) and OLS regression. The data for the study were collected with the use of wellstructured questionnaires from poultry farmers. Average number of birds for small farm size is 301, for medium farm size is 740, while that of large size is 2288. The corresponding net returns were...
full textFuzzy data envelopment analysis: A discrete approach
Data envelopment analysis (DEA) as introduced by Charnes et al [3] is a linear programming technique that has widely been used to evaluate the relative efficiency of a set of homogenous decision making units (DMUs). In many real applications, the input-output variables cannot be precisely measured. This is particularly important in assessing efficiency of DMUs using DEA, since the efficiency sc...
full textFuzzy data envelopment analysis: A fuzzy expected value approach
Performance assessment often has to be conducted under uncertainty. This paper proposes a ‘‘fuzzy expected value approach’’ for data envelopment analysis (DEA) in which fuzzy inputs and fuzzy outputs are first weighted, respectively, and their expected values then used to measure the optimistic and pessimistic efficiencies of decision making units (DMUs) in fuzzy environments. The two efficienc...

It is well known that Data Envelopment Analysis (DEA) is a relative efficiency measurement tool, which uses optimization techniques to automatically calculate the weights assigned to the crisp deterministic multiple inputs and outputs of a set of the Decision Making Units (DMUs) being assessed. However, crisp deterministic data requirement delimits an application to the real world problems wher...
full textA fully fuzzy approach to data envelopment analysis
Data envelopment analysis (DEA) is a method to evaluate the efficiency of some decision making units which by using one or more inputs will make one or more outputs. In real world, most of the problems don’t have a certain mode. Fuzzy theory is one of the ways of considering uncertainty in the mathematical programming problems. In this study by using this idea, the DEA model on a fully fuzzy mo...
