Abstract: Incorporating value judgments in data envelopment analysis (DEA)
is a broad methodological framework that facilitates driving the efficiency
assessments in line with individual preferences. Value-based DEA is a recent
development that resorts to value assessment protocols from multiple criteria
decision analysis (MCDA) to transform the original input/output data to
a value scale. In this context, we introduce in this paper a piece-wise
linear programming approach to value-based DEA, by employing a data
transformation-variable alteration technique and assurance region constraints.
We outline our approach by revisiting a previous efficiency assessment study
drawn from the literature.
