In view of the liner schedule recovery problem after the delay, three recovery measures were adopted, including adjusting the speed , canceling the port of call and shortening the time in port. Taking into account of the economic benefits of liner companies and the shippers' satisfaction, the fuzzy time window was introduced to quantify the shippers' satisfaction as a fuzzy membership function of liner delay time, and a bi-objective model with minimum liner operation cost and the maximum owner satisfaction was established. An improved NSGA-II algorithm nested orthogonal search strategy was designed to find the Pareto-front non-inferior solution set which meet the needs of both liner company and shipper. Finally, a practice example was used to verify the effectiveness of the model and the superiority of the improved algorithm. The results show that the model and algorithm can provide a decision-making reference for liner company in different market conditions.
