Simulation model and its algorithms for disruption management<br /> of berth scheduling<br />
Journal Title: Science Paper Online - Year 2009, Vol 4, Issue 10
Abstract
The disruption management problem of berth scheduling is studied, the objective is to decrease the influence of unforeseen disruptions to operation system and decrease the addition cost resulting from disruptions. Firstly, a disruption management model for berth scheduling is developed. Then, the simulation model is integrated with optimization algorithm to optimize the new berth schedule to deal with disruptions. In this method, simulation model is used to evaluate a given schedule; and optimization algorithm is used to search the optimal schedule. To improve the computation efficiency of simulation optimization model, an algorithm based on local rescheduling and tabu search is designed. Finally, numerical experiments are provided to illustrate the validity of the proposed model and algorithms.
