Data Envelopment Analysis (DEA), which avoids the critical assumption that the performance parameters are mutually independent, appears as an effective decision tool for the robot selection problem. However, a robust robot selection procedure necessitates the consideration of both quantitative criteria such as cost and engineering attributes, and qualitative criteria, e.g. vendor-related attributes, in the decision process. Qualitative attributes may be indicated by using linguistic variables

When multiple efficient robot alternatives are identified as a result of the analysis, cross efficiency analysis is used to discriminate between the alternatives, and thus, to determine the best robot alternative. A comprehensive example is presented to illustrate the decision-making procedure.
