Abstract: Highlights•A diverse-skilled technician organization and routing model is developed for service networks.•Global optimization integrates dynamic maintenance schemes and technician team compositions.•A limited pool of technicians with varying skill levels supports maintenance activities.•A hybrid metaheuristic algorithm is proposed to approximate Pareto-optimal solutions.•Bi-objective maintenance framework helps lessors to arrange the most appropriate scheme.
