Municipal waste management using multiple disposal location arc routing and waste segregation approach - a real life case study in England

Abstract

Abstract The management of municipal solid waste (MSW) is recognized as one of the most important operations in municipalities. It calls for significant amounts of both fixed and variable costs and investments. The majority of these costs are comprised of the operational procedures of collecting, transportation, and disposal. Within the scope of this paper, multiple disposal location arc routing problems (LARP) with vehicle capacity limitation and consideration of waste segregation are investigated. The LARP model will point out the optimal places for the depot as well as the three trash disposal sites. In other words, waste segregation is analyzed in this problem. The different types of optimization objectives and constraints on LARP model are concentrated towards improving waste collection and minimizing the cost. Also, a triangle fuzzy parameter is defined as the demand. Furthermore, future research gaps are identified by investigating of various key issues of the existing methods. A real case study is investigated in UK to test the performance and applicability of the proposed model. Finally, several sensitivity analyses are performed with useful managerial insights in different conditions to analyze the changes in the objective function.
