A new approach for vague risk analysis based on the ranking of trapezoidal vague sets is proposed. Firstly, a new method for ranking of vague sets is presented. Then, the proposed method is applied to developed a new method for dealing with vague risk analysis problems. This analysis helps us to find out the probability of failure of each components of combustion system, which could be used for...

Society for Risk Analysis (Europe) Conference From the everyday to the extraordinary: challenges for risk analysis and management

This paper proposes a Cross Impact Analysis for supporting critical infrastructures risk analysis. This methodology contributes to decision-makers and planners with analytical tools for modeling complex situations. These features are generally useful in emergency management and particularly within the critical infrastructures scope, where complex scenarios for risk analysis and emergency plans ...

This paper reports the results of a study aimed at understanding and characterising IT management sophistication in small businesses. A multiple-case study approach was therefore used to explore the IT management practices of small businesses. Data collection involved four small-medium chartered accountancy (CA) firms and three IT firms closely associated with the CA industry. The case results ...

The risks posed by management are neither addressed by risk analysis nor included in safety cases. Yet they have been shown to be significant contributors to accidents. This paper argues for more attention to be paid to them and for the development of a risk-analysis method to address them. The paper examines the aspects of management risk that it might cover and offers a set of proposals for i...

This paper discusses some models of Imprecise Probability Theory obtained by propagating uncertainty in risk analysis when some input parameters are stochastic and perfectly observable, while others are either random or deterministic, but the information about them is partial and is represented by possibility distributions. Our knowledge about the probability of events pertaining to the output ...

Digital application marketplaces are increasingly relevant for digital platform owners seeking to reap the benefits of distributing, brokering, and operating applications by third-party developers. Owners of such marketplaces have two vital goals: address the needs of heterogeneous end-users and attract third-party developers. A key element in simultaneously accommodating these goals is value c...

At eSmart 2003, Kekicheff and Brewer [1] reported on the development of the GlobalPlatform Card Security Requirements Specification (CSRS) [2]. They pointed out not only that the CSRS presents a semi-formal security specification for the entire card platform, but also that it proposes a method for selecting the most appropriate card configuration based on risk analysis. Particular attention was...

This paper addresses the concept of model uncertainty within the context of risk analysis. Though model uncertainty is a topic widely discussed in the risk analysis literature, no consensus seems to exist on its meaning, how it should be measured, or its impact on the application of analysis results in decision processes. The purpose of this paper is to contribute to clarification. The first pa...
