The role of multiplier bounds in fuzzy data envelopment analysis
The non-Archimedean epsilon ε is commonly considered as a lower bound for the dual input weights and output weights in multiplier data envelopment analysis (DEA) models. The amount of ε can be effectively used to differentiate ...
Dual-Role Factors for Imprecise Data Envelopment Analysis
Efficiency analyses are crucial to managerial competency for evaluating the degree to which resources are consumed in the production process of gaining desired services or products. Among the vast available literature on ...
Fuzzy Efficiency Measures in Data Envelopment Analysis Using Lexicographic Multiobjective Approach
There is an extensive literature in data envelopment analysis (DEA) aimed at evaluating the relative efficiency of a set of decision-making units (DMUs). Conventional DEA models use definite and precise data while real-life ...
Measurement of Returns-to-Scale using Interval Data Envelopment Analysis Models
The economic concept of Returns-to-Scale (RTS) has been intensively studied in the context of Data Envelopment Analysis (DEA). The conventional DEA models that are used for RTS classification require well-defined and ...
