Prioritizing the indicators responsible for sustainable municipal solid waste management using SF-AHP and SF-TOPSIS

Abstract Municipal corporations of small cities in India are struggling with the challenges that emerge from the unstructured solid waste management system. For successful implementation of the Municipal solid waste management system, all the basic components of this system need to work effectively and efficiently. Identification of performance indicators is completed with the help of a literature review and experts information. Interviews were conducted with the experts working in the field of solid waste management and three decisions criteria i.e., importance, performance, and understandability were defined to evaluate the selected performance indicators. For uncertainties, criteria weights were established using the spherical fuzzy analytical hierarchy process approach and the combined pairwise comparison matrix was aggregated by applying the spherical fuzzy TOPSIS method. Eventually, the indicators responsible for sustainable waste management were selected and ranked. An assessment of the conceptual framework of MSWM is also proposed for practical implementation of the ranked indicators for the MSWM system in Dinanagar and other cities with similar situations.
