A novel real number encoding method of Particle Swarm Optimization (PSO) for Vehicle Routing Problem is proposed. Objective is to solve the vehicle routing problem with fuzzy demands (FVRP), in FVRP, a fuzzy chance constrained program model is designed, based on fuzzy credibility theory. numerical experiments are carried out, and the algorithm is compared with other heuristic methods for the same...
This paper presents a development of the assets management system that purposely aspires to assist the Department of Highways (DOH), Ministry of Transportation, Thailand in managing their assets. Currently, the DOH has over hundred billions Thai Baht or approximately three billions USD in assets under management, which require a constant maintenance. The study initially focuses on an assessment of...
The Based on the analysis of the connotation about urban transportation sustainable development in Shandong Province and its present situation, this paper constructed appraisal index system about urban road transportation sustainable development ability and established fuzzy analytic hierarchy process model (FAHP) to make synthetic evaluation on it from five aspects such as urban road infrastructure...
In order to strengthen management of road hazardous materials transportation, safeguard public interest and social safety, the influence factors that affect the safety supervision level of hazardous materials transportation are systematically and comprehensively analyzed, then the evaluation index system is formed and the index weight is determined with the analytical hierarchy process method. Furthermore,...
This paper illustrates the environmental factors critical to the successful implementation of ISO 14001. The analytic hierarchy process (AHP) methodology was applied to find out the relative weights and priorities of these environmental factors. With the combination of the methodology of the AHP and the environmental factors listed in ISO 14001, a case study has been carried out on the port of Shanghai...
Based on the aviation passenger satisfaction indices and subjection matrix, this paper presents an evaluation system about aviation passenger satisfaction degree firstly. According to comprehensive multi-level fuzzy evaluation method, it builds the fuzzy comprehensive evaluation model for the degree of aviation passenger satisfaction. Then, it determines indices about aviation passenger satisfaction...
Logistics node is one of the key points in the logistics network and logistics resources integration.As a result, the selection and scheduling of the impact factors of the nodes are important to the design of logistics network. In Ningbo, the logistics network is based on ports and stations. We can evaluate and analyze of the selection and scheduling of the impact factors of the nodes by the method...
For making comprehensive evaluation of the highway network programming project be more flexible, objective and credible, this paper bases on DEA theory, establishes a non-parameter DEA model, by building up a comprehensive evaluation index system from the supply and demand aspects, by direct input and output method, carried out a comprehensive evaluation on the highway network for the purpose of optimizing...
