A multicriteria model on calculating the Sustainable Business Excellence Index of a firm with fuzzy AHP and TOPSIS
Purpose The purpose of this paper is to provide an integrated methodology for benchmarking the sustainability of organizations. The fuzzy analytical hierarchy process (FAHP) and technique for order of preference by similarity to ideal solution (TOPSIS) methods have been used for this purpose. The FAHP is used to determine the weights of the criteria by decision makers, and the rankings of the alternatives are determined by TOPSIS. The proposed instrument is used to calculate the Sustainable Business Excellence Index (SBEI) and its potential impact on the formulation of firm strategy. To demonstrate the applicability of the model, illustrative examples are presented. Design/methodology/approach After a careful literature review, a sustainable business excellence framework is created and a fuzzy system is developed to assess firms' sustainability. Finally, the SBEI is computed. Findings The results indicate that the suggested fuzzy approach is feasible for benchmarking the sustainability of organizati.
