Research And Development Of The Optimum Route Optimization For Acceptance And Delivery Of The Railway Express Freight

In the railway express freight transportation process,transportation costs accounted for the proportion of the total cost greatly,especially the "last mile" transportation of the railway express,even directly influences the efficiency of railway express freight,however,in the actual situation,which may lead to the decline of the transportation service level due to the unsuitable route choice,but because the low degree of field efficiency and information,all links accepting and delivering express freight are independent,and the delivery of express freight without real-time information feedback,therefore,it is necessary to develop the system of choice and optimization for the acceptance and delivery of transportation routes for railway express freight.In this paper,researching and analyzing the choice and optimization of the transportation route for railway express freight at home and abroad,in view of the existing problems,the main contents and ideas of this paper are presented.In this paper,according to the basic theory of the acceptance and delivery of railway express freight and the basic concept and characteristics of vehicle routing problem,the paper analyzes the transportation process of railway express freight,and establishes the transportation route choice and optimization model of the acceptance and delivery of railway express freight,the model takes the minimum total transportation cost as the goal,mainly considering the constraints of the vehicle weighing,the transportation time and the uniqueness of the vehicle arriving and departing the customer point in the process of accepting and delivering,after analyzing the algorithm to solve these problems,the method of rule engine is proposed to solve the problem.On the basis of the theory of the rule engine,this paper divides the railway express delivering and accepting process into two kinds of situations by means of logical thinking,the first one is that the process of accepting and delivering the distribution vehicle of the express freight is carried out separately,the second is that the process of accepting and delivering the distribution vehicle of the express freight is carried out at the same time,and the two cases are respectively carried out stage division and rule-making to ensure that it is consistent with the actual situation.Finally,with the model as the foundation,through the analysis of demand,combined with object-oriented design philosophy and database technology,the design and development of the system of choice and optimization for the acceptance and delivery of transportation routes for railway express freight,which is based on the rule engine theory,through the adjustment of the rules in the rule base of the system,it can realize the intelligent choice of the transportation route of the railway express freight accepting and delivering.The development of the system of choice and optimization for the acceptance and delivery of transportation routes for railway express freight can not only improve the transportation efficiency and information level to some extent,but also provide some reference for the following research.
