Human, machines and environment, three main factors contained in transport system in coal mines, and their impact on transport accident have been analyzed with system engineering theory of man-machine-environment in this article. Reasons and control of human mistakes, relationship between human and transport accident, analysis of machines' stability and fuzzy comprehensive evaluation have been deeply...
Based on detailed analysis of maritime hazadous cargo transportation, maritime hazadous cargo transportation evaluation index system is established. The index system is characterized by the complicated hierarchy structure and multiple index attributes. A methodology is structured to evaluate hazardous waste transportation firms containing the methods of fuzzy-AHP and comprehensive evaluation. An example...
Chinese oil transportation security is evaluated based on the multi-step fuzzy comprehensive evaluation approach. The results show that Chinese oil transportation lines are in the optimal order: Kazaks tan-China, South America-China, Middle East-China, West Africa-China, and Russia-China. Finally some suggestions on Chinese regional cooperation are made to ensure oil transportation security.
There is all kinds of risk consisting in every logistic transportation link of product oil because of the bigeer product oil transportation district and the more complex transportation goods, a wide variety, quantity, and so on. Any question in a single Spoken of earlier link happened will affect accuracy, security and timeliness of indicator. This paper constructs evaluation index system and evaluation...
By analyzing the module and concrete items of risks in ship pilotage, applying Grey theory analysis, brings forward the Grey Theory Analysis Model in ship pilotage risks analysis, Moreover, fuzzy function is taken in the analysis of relative risk factors, achieving the optimal relational coefficient of piloting risk factors, and finally obtaining the relational degree taxis. As indicated in the computing...
To investigate the safety of urban mass transit, the forewarning grade of emergency is evaluated with the fuzzy sets theory. The new fuzzy evaluation method shows how the interrupt time, casualties, happen position, property loss and sphere of influence affect the forewarning grade of emergency in urban mass transit system. The results demonstrate that fuzzy evaluation not only fulfill the comprehensive...
In this paper, we present a novel safety assessment approach to marine traffic based on cloud models, where various uncertainties in the complex system are well investigated and modeled by cloud theory. The proposed method focuses on the effective model of involved qualitative and quantitative elements in marine traffic safety systems. Optimal cloud models based on the relative cloud theory are used...
It was an important to improve urban transportation management level by carrying out urban transportation management planning. According to the characteristics of urban transportation management planning, the evaluation model of urban transportation management planning project was studied based on fuzzy theory. First, the 14 evaluation index of urban transportation management planning project was...
This work describes the method of quality evaluation of cargo transportation based on the complex system of interrelated and interactive management components. The quality of the transportation service of the enterprises mostly depends on the conformity of the vehicles design to its operation conditions, nature of the transportation process, and convenience of loading and unloading works execution...
It is essential to do the evaluation on road passenger transportation enterprise's industrial safety impersonally, scientifically and rightly at present in order to reduce the traffic accident in China. This article establishes the industrial safety evaluation index system for road passenger transportation enterprise based on the rule of ministry of transport of the People's Republic of China and...
In order to realize evaluation of oil storage safety, clear the redundant data in indexes membership which is not useful for goal classification, based on data mining of entropy, mining knowledge information about object classification hidden in every index, affirming the relation of object classification and index membership, eliminating the redundant data in index membership for object classification...
This paper proposes a Fuzzy Synthesis Evaluation Procedure to evaluate urban road safety. AHP method is applied to construct bi-level evaluation system of urban road safety. And then, the weight of urban road safety evaluation index is determined by expert questionnaire approach. Finally, fuzzy synthesis evaluation model is developed. The level of urban road safety is determined by centesimal system...
To investigate the safety of route flight in air traffic management, the collision risk is evaluated with the fuzzy sets theory. The new fuzzy evaluation method shows how the communication, navigation, surveillance, operation error, and traffic density influence the risk of collision in the parallel routes. The results demonstrate that fuzzy evaluation not only fulfill the safety assessment of separation...
