Abstract:  Uncertainty on transportation time is an important aspect of the fourth party logistics (4PL) routing problem. Reliability theory is applied to routing optimization for this problem. Based on multi-graph, a chance constrained programming model for routing optimization problem of 4PL is set up. In this model, it takes the minimum cost as objective and the time reliability as constraint. By analyzing the characteristics of the problem, a messy genetic algorithm with double arrays encoding is developed. The performance of the algorithm is tested by examples. Experimental results demonstrate the significance of the model as well as the effectiveness of the proposed algorithm. According to the time reliability requirements of the customers, the algorithm can quickly and effectively provide the optimal solution to decision-makers.
