A fresh look at the system analysis helped us in finding a new way of calculating the risks associated with the system. The author found that, due to the shortcomings of RPN, more researches needed to be done in this area to use RPNs as a new source of information for system risk analysis. It is the purpose of this article to investigate the fundamental concepts of failure modes and effects ana...

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...

To overcome the uncertainty of the weights and the assessment matrix, which are adopted by fuzzy comprehensive method, the entropy weight with objectivity is used to determine the weight in this paper. And the accurate assessment matrix are built using the fuzziness and randomness of comprehensive cloud model. Then the risk comprehensive assessment model of CCS project is established. So qualit...
