In this paper, we present a new fuzzy risk analysis method based on generalized fuzzy numbers. Firstly, we define new arithmetic operations between generalized fuzzy numbers. Then, we propose a new method to measure the degree of similarity between generalized fuzzy numbers. Finally, we apply the new arithmetic operations between generalized fuzzy numbers and proposed similarity measure to deve...
Introduction: Organizations, manufacturing and non-manufacturing companies, and development units are always associated with incidents and the need for proper risk assessment. One of these is the process of constructing subwayways that, given its nature, require special attention and the occurrence of accidents is always there. But as risk definition is clear, risk is always associated with unc...
multi attribute decision making methods are considered as one of the most useful methods for solving ranking problems. in some decision making problems, while the alternatives for corresponding criteria are compared in a pairwise comparison manner, if the criteria are inherently fuzzy, debates will arise in ranking alternatives due to the closeness of the values of the criteria. in this researc...
in the emerging supply chain environment, green supply chain risk management plays a significant role than ever. risk is an inherent uncertainty and has tendency to disrupt the typical green supply chain management (gscm) operations and eventually reduce the success rate of industries. in order to mitigate the consequences, a fuzzy multi-criteria group decision making modeling (fmcgdm) which co...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
This paper discusses hybrid probabilistic and fuzzy set approaches to propagating randomness and imprecision in risk assessment and fuzzy time series models. Stochastic and Computational Intelligence methods, such as Probability bounds analysis, Fuzzy -levels analysis, Fuzzy random vectors, Wavelets decomposition and Wavelets Networks are combined to capture different kinds of uncertainty. The...
Background and Aim: Based on the Iranian Social Security Organization statistics, in 2012 the accidents occurring in the construction industry accounted for 26% of all the occupational accidents in the country. Therefore, this study was conducted to identify the individual and occupational risk factors affecting the causes of occupational accidents in this industry using the fuzzy hierarchical ...
The traditional event tree analysis uses a single probability to represent each top event. However, it is unrealistic to evaluate the occurrence of each event by using a crisp value without considering the inherent uncertainty and imprecision a state has. The fuzzy set theory is universally applied to deal with this kind of phenomena. The main purpose of this study is to construct an easy metho...
This paper provides a Fuzzy based decision support system (DSS) for risk analysis in E-tourism ( Electronic Tourism ) investment. In general term, E-tourism is the use of information and communication technology (ICT) in tourism which may allow operating tourism in least variable cost, least time and increased work efficiency. It is worth noting that there are many factors that affect the deve...
