Abstract :
Data envelopment analysis (DEA) is a method for recognizing the efficient frontier of
decision making units (DMUs).This paper presents a Context-dependent DEA which uses the interval
inputs and outputs. Context-dependent approach with interval inputs and outputs can consider a set of
DMUs against the special context. Each context shows an efficient frontier including DMUs in
particular levels. The Context-dependent DEA with interval inputs and outputs can measure (i) the
attractiveness when DMUs showing weaker performance are selected as an appraisal context, and (ii)
the interval progress when DMUs showing better performance are selected as the appraisal context.
