Integrating fuzzy Delphi with graph theory and matrix methods for evaluation of hazardous industrial waste transportation firm

Hazardous and toxic industrial wastes may cause or significantly contribute to extensive damage to both humans and the environment when improperly handled. Evaluation of the proper and most appropriate hazardous industrial waste transportation firm is an important problem for hazardous waste generators. In this paper, a simple, systematic and logical scientific approach is structured to evaluate hazardous industrial waste transportation firm through integrating fuzzy Delphi method (FDM) with graph theory and matrix approach (GTMA). Fuzzy Delphi method used to identify the most important and significant criteria and most probable service providers, and graph theory and matrix approach evaluate and rank those transportation service provider firms. To accredit the proposed model, it is implemented in an automotive battery manufacturing company in Bangladesh.
