Abstract
In view of the characteristics of the express freight transportation network such as multi-mode operations and high requirements for delivery service,the method for determining the capacity of the express freight transportation service network was put forward under constraint of reliability of the delivery time.The hybrid intelligent algorithm was designed,which integrated the genetic operation and Monte Carlo simulation.Referring to the existing relevant literature,results of a numerical case show as follows: When the demand level of express freight transportation is low,the express freight transportation service network is able to finish all freight assignments at the required delivery time;when the express freight transportation demand reaches a very high level,the reliability of the express freight transportation service network decreases dramatically,i.e.,in the case of congestion,the reliability of on-time delivery is hard to be guaranteed.
