چکیده مقاله:

Waste collection problem is one of the most important logistical issues faced by municipalities, which is widely dependents on route optimization. In this paper, a bi-objective model that simultaneously minimizes operational and environmental costs and population exposure risk is presented. The problem consists of waste collection activities and disposing those wastes in related disposal facilities. This model seeks to find the best possible way to achieve the objectives of the problem with available constraints by a heterogeneous fleet of vehicles that have different traveling time limitations. Due to the fact that the population of people living on the routes are imprecise and traveling time between sites are not certain, fuzzy numbers are considered for those parameters. For the validation of the presented model the problem is solved by GAMS and the results of CPLEX solver by using epsilon constraint method are shown
