This paper is devoted to the presentation of a risk-management methodology specifically developed for assessing and analysing risks incurred by the business transactions of an organisation. A transaction is a part of a business information system that has one or other functional goal. An order-entry-and-delivering-ofgoods transaction forming part of an MRP (materials, requirement & planning) in...

Fuzzy theory and Bayesian network theory were based on the fault tree. The fault tree analysis method improved the fault analysis to obtain number of event's exact problem. Considering the characteristics of the fuzzy risk analysis at the same time, it also solved the problem of scale fault analysis modeling. The theory is applied to the cost of construction shield tunnel risk analysis, floatin...

The unavailability of sufficient data and uncertainty in modeling, some techniques, and decision-making processes play a significant role in many engineering and management problems.  Attain to sure solutions for a problem under accurate consideration is essential.  In this paper, an application of fuzzy inference system for modeling the indeterminacy involved in the problem of HSE risk assessm...

Failure mode and effects analysis (FMEA) is a popular and useful approach applied to examine potential failures in different products, designs, processes, and services. As a vital index, the risk priority number (RPN) can determine the risk priorities of failure modes by some risk factors such as occurrence (O), severity (S), and detection (D). However, in FMEA, the traditional risk priority nu...

the build-operate-transfer (bot) projects are a popular method of privatization of public infrastructure development. there are several risks which might affect a bot project negatively. concession period is one of the most important decision variables in arranging a bot-type contract which should be determined considering the existing risks and uncertainties. a longer concession period is more...

in recent decade, several methodologies and tools have been developed to undertake a risk analysis in order to prevent accidents in the process industries. attempts have been made to study and compare these methods. however, yet no method has been proposed to aid managers in a scientific selection of a proper risk analysis method. in this paper, we have presented a multi criteria decision makin...

In this paper, the author analyzed the synthetic four dimensional evaluation index systems on risk of carbon finance in commercial banks in China. The analysis was conducted by means of an AHP-based Fuzzy Approach which builds a system analysis technique for multiple criteria decision making, and by market risk, credit risk, operational risk and project risk. The result show that evaluation ind...

in order to have better insight of project characteristics, different kinds of fuzzy analysis for project networks have been recently proposed, most of which consider activities duration as the main and only source of imprecision and vagueness, but as it is usually experienced in real projects, the structure of the network is also subject to changes. in this paper we consider three types of imp...
