This research develops an evolution strategy-based multi-objective optimization approach to handle a green transportation scheduling problem with some distinct realistic features. The problem is formulated as a bi-objective mixed integer nonlinear program. The effectiveness of the proposed approach is evaluated by numerical experiments based on industrial data. Experimental results demonstrate that the proposed approach can solve the investigated problem effectively.

“…Many variants of VRPs have been developed to tackle various constraints, such as Capacitated VRP (CVRP), VRP with Time Windows (VRPTW), Multiple Depot VRP (MDVRP) an so on [3]. The VRP not only plays an important role in industrial production but also gets widely applied to other areas [4], such as Supply Chain Logistics [5], Emergency Preparedness [6], Green Logistics [7] and Patient Transportation [8].…”

Abstract:Many government agencies and business organizations have realized that it is necessary to consider not only the economic cost but also the road transport emissions when they determine the transport policies and operations. In this study, a patient transportation problem with the aim of reducing transport emissions has been formulated by implementing CVRP model. In order to determine the routes of patient transportation with optimized emissions for targeted hospital, an improved Cuckoo Search (ICS) algorithm is proposed. In this study, a 'split' procedure has been implemented to simplify the individual's representation. A new category of cuckoos has been introduced to improve the ICS's search ability. Two heuristics have been applied to improve the quality of initial population. A local search mechanism has been embedded in the search procedure to improve the quality of solutions obtained at the end of each iteration. The computational results were encouraging and demonstrated the effectiveness of the proposed solution method.
