The lockage co-scheduling problem of the five locks in the Three Gorges Project is studied. Itpsilas an NP-hard combinational optimization with large dimension coursed by the multi chamber sizes, multi lockage styles and large quantity of vessels. A simulation based parallel genetic algorithm (SBPGA) is proposed to make each lock optimized locally and(More)
Purpose – The purpose of this paper is to propose a rolling horizon procedure (RHP) to deal with the large-scale and strongly NP-hard problem on cooperative lockage-timetables and service-policies of the five locks in the Three Gorges Project. Design/methodology/approach – RHP based approach is composed of a series of periodical short-time sub-optimizations(More)
The lockage co-scheduling problem of the five locks in the Three Gorges Project is studied. Itpsilas an NP-hard combinational optimization with large dimension coursed by the multi chamber sizes, multi lockage styles and large quantity of vessels. As a traffic scheduling, the operation strategy of each waterway-controller, i.e. the lock, is the key of(More)
