Considering responsiveness and environmental impacts, this paper presents a novel sustainable hub location-vehicle scheduling model, in which transportation fleet at hub nodes serving customers are limited in number. Because of this limitation, assignment and sequencing of outbound vehicles at each hub is taken into consideration. Therefore, each hub node performs as a scheduling and sequencing problem. The model considers perishability of products for distribution in a food supply chain and considers total CO2 emission of hub network, simultaneously. The problem is modeled as a multi-objective mixed integer linear programming optimizing the total transportation costs, freshness and quality of foods at the time of delivery and the total carbon emissions of the vehicles to fulfill the sustainability desire of the environment. Due to NP-hardness of the problem, an adopted non-dominated sorting genetic algorithm-II (NSGA-II) Meta heuristic approach is proposed to solve large instance problems. Numerical experiments are performed on CAB and AP datasets. Numerical tests confirms that the proposed meta-heuristic is able to generate proper Pareto solutions considering all of the objectives for decision maker.
