| Abstract: | Based on credibility theory,this paper will present a class of transportation planning chance-constrained model with fuzzy parameters.Then it deals with approximation approach and designs a huristic algorithm,which combines approximation approach, nural network and genetic algorithm,to solve this fuzzy transportation planning chance-constrained model.Finally,it gives a numerical example to show the practicality and effectiveness of the designed algorithm. |
