Abstract: Considering that in the Fourth Party Logistics (4PL), customers' demand is changing with the time or envir-onmental parameters, a problem for 4PL Routing Problem with Stochastic Demand (4PLRPSD) is proposed. With the analysis of the stochastic demand, a mathematical model for the 4PLRPSD is built based on the stochastic programming methods with subjective preferences. Taking into account the character that the problem needs to choose a constrained shortest path in the multi-graph, a genetic algorithm based on the double array priority coding method with stochastic simulation is proposed. The experimental results show that with the different duration time, the transportation cost increases with the credibility level.

Key words: fourth party logistics, routing problem, stochastic demand, priority coding method, genetic algorithm
