Abstract


In the the wharf line limited resources , a reasonable berth scheduling scheme can effectively shorten the time of the ship in the port terminal production efficiency , thereby increasing the pier itself competitiveness . Berth scheduling problem is the problem of container terminal production organization optimized basis , and its task is to determine the ship berthing location and berthing time under the conditions of limited resources in the number of berths , the number of job quay crane , wharf front yard scale , thus a reasonable arrangement shore bridge loading and unloading operations , in order to ensure that the production targets selected optimal . Due to the extensive use of the way of liner shipping , container terminal scheduling management staff schedules and information such as the amount of loading and unloading boxes can be provided in the shipping companies to Hong Kong before , in advance of berth scheduling plan , ordered the ship into port operations . Currently , most of the container berths scheduling theory using the dispatch optimization methods for static production environment , consider scheduling plan execution process , internal and external environment does not change . However , in the actual production , berth scheduling often be faced with a very complex environmental uncertainty , which makes this static scheduling optimization methods are often difficult to meet production needs . To this end , this paper presents a dynamic rolling window berth scheduling optimization method : First establish minimize ship an average degree of deviation in the time of arrival and berthing order multi-objective optimization model ; solving the model , cycle-based and event - driven mixed re - scheduling mechanism scheduling process into a continuous static scheduling intervals within each interval Memetic algorithm to optimize the scheduling window ship set . Example , solving the initial scheduling program , and for emergency berthing of the ship , the ship delayed to Hong Kong as well as shore bridge failure three , respectively, re- scheduling , and the re- scheduling scheme . The results show that , relatively static scheduling method , based on the dynamic rolling window berth scheduling optimization method can adapt to the complex dynamic production environment , the optimization results more in line with the the container berths scheduling practice needs .
