In this chapter, an integrated fuzzy data envelopment analysis (DEA) is proposed for evaluating different departments of a company with respect to the occupational safety investment. The inputs in the DEA methodology are occupational safety investments classified as A, B, C, and D-type investments according to their level in hierarchy of preventive and protective measures. The outputs in the DEA methodology are occupational safety related performance measures and business environment related performance measures. The t-norm and t-conorm fuzzy relations are used for the defuzzification of the fuzzy CCR-based DEA model.
