چکیده
In order to effectively reduce the probability of subway operation accidents and explore key risk factors multi-factor coupling mechanism during period, this paper classifies affecting safety into four categories primary factors, personnel, equipment facilities, environment management, introduces emergency management concept identify 18 secondary combines improved fuzzy decision making test evaluation laboratory (DEMATEL) Explanatory Structure Model (ISM) visualize factor action relationship, construct a six-order hierarchical recursive structure model for accidents, relationship effect between from perspective single factor, double multiple establish metric based on Natural Killing (N-K), carry out information interaction scenario combination quantification calculation, finally integrate DEMATEL-ISM-NK correct centrality, determine in macro micro analysis, qualitative quantitative research, propose prevention control strategies accordingly. The results show that six such as social environment, are be prevented metro system. Multi-factor leads higher controlling involvement is an effective means occurrence accidents.

متن کاملFuzzy model for risk analysis
The goal of this paper is to show how the concept of fuzzy logic can be used to establish a degree to which an investment project belongs to a class of risk. Also, the probability of the fuzzy event is presented and is ap-plied to calculate the probability of the fuzzy event “the project X is a good investment”. This process has to enable the decision maker to compare several alternative invest...

Automobile hull insurance has attracted much attention due to the high rate of vehicle applications in daily lives. Since purchasing these policies is optional in Iran and their premium rates are set competitively, a competition is formed among the insurance companies for attracting low risk drivers. However, most of the insurers still use comparative rates and pay no or less attention to the f...
