Trung Hieu Tran, a former Research Fellow of the PortForward project team at Brunel University London and current Lecturer at Cranfield University, will present a paper out of his work in the WP5 of the PortForward project (Green Scheduling and Sustainability of Operations) titled »A Multi-objective Optimization Model For Green Yard Scheduling Problem In Container Terminals« in the 2020 INFORMS Annual Meeting Virtual, co-authored with Afshin Mansouri, PI, and Cihan Butun, a Research Fellow of Brunel University London’s PortForward Project Team, which will be held online 8-11 November 2020. The conference is the main forum of the Institute for the Operations Research and Management Science (INFORMS) and provides an opportunity to showcase the PortForward project among the OR/MS community.
Abstract for Presentation
»A Multi-objective Optimization Model For Green Yard Scheduling Problem In Container Terminals«
In this paper, a multi-objective mixed-integer linear programming model is proposed to seek the optimal scheduling of equipment operations in container terminals. The model aims to simultaneously minimize total tardiness of all jobs (e.g., stacking, retrieving and reshuffling containers) and total energy consumption of rubber-tyred gantry cranes (RTGs) and reach stackers (RSs). Due to operational safety, RTGs are only allowed to shift intra-bay containers and RSs are used to shift inter-bay containers. Numerical experiments, carried out on a set of randomly generated instances, show that our model can obtain the optimal scheduling within a reasonable computation time.
