  • intelligent adversary Risk Analysis a bioterrorism Risk management model
    Risk Analysis, 2010
    Co-Authors: Gregory S. Parnell, Christopher M Smith, Frederick I Moxley
    Abstract:

    The tragic events of 9/11 and the concerns about the potential for a terrorist or hostile state attack with weapons of mass destruction have led to an increased emphasis on Risk Analysis for homeland security. Uncertain hazards (natural and engineering) have been successfully analyzed using probabilistic Risk Analysis (PRA). Unlike uncertain hazards, terrorists and hostile states are intelligent adversaries who can observe our vulnerabilities and dynamically adapt their plans and actions to achieve their objectives. This article compares uncertain hazard Risk Analysis with intelligent adversary Risk Analysis, describes the intelligent adversary Risk Analysis challenges, and presents a probabilistic defender-attacker-defender model to evaluate the baseline Risk and the potential Risk reduction provided by defender investments. The model includes defender decisions prior to an attack; attacker decisions during the attack; defender actions after an attack; and the uncertainties of attack implementation, detection, and consequences. The Risk management model is demonstrated with an illustrative bioterrorism problem with notional data.

    Abstract:

    Abstract : The tragic events of 911 and the concerns about the potential for a terrorist or hostile state attack with weapons of mass destruction have led to an increased emphasis on Risk Analysis for homeland security. Uncertain hazards (natural and engineering) have been analyzed using Probabilistic Risk Analysis (PRA). Unlike uncertain hazards, terrorists and hostile states are intelligent adversaries who adapt their plans and actions to achieve their strategic objectives. The critical Risk Analysis question addressed in this paper is as follows: Are the standard PRA techniques for uncertain hazard techniques adequate and appropriate for intelligent adversaries? Our answer is an emphatic no. We will show that treating adversary decisions as uncertain hazards is inappropriate because it provides the wrong assessment of Risks. Specifically, the paper compares uncertain hazard Risk Analysis with intelligent adversary Risk Analysis, describes the intelligent adversary Risk Analysis challenges, and uses a defender-attacker-defender decision Analysis model to evaluate defender investments. The model includes defender decisions prior to an attack; attacker decisions during the attack; defender actions after an attack; and the uncertainties of attack implementation, detection, and consequences. In section 1, we describe the difference between natural hazards and intelligent adversaries and demonstrate, with a simple example, that standard PRA does not properly assess the Risk of an intelligent adversary attack. In section 2, we describe a canonical model for resource allocation decision making for an intelligent adversary problem using an illustrative bioterrorism example with notional data. In section 3, we describe the illustrative Analysis results obtained for the model and discuss the insights they provide for Risk management. In section 4, we describe the benefits and limitations of the model. Finally, we discuss future work and our conclusions.

  • fuzzy Risk Analysis based on ranking generalized fuzzy numbers with different heights and different spreads
    Expert Systems With Applications, 2009
    Co-Authors: Shyiming Chen, Jimho Chen
    Abstract:

    In this paper, we present a new method for fuzzy Risk Analysis based on ranking generalized fuzzy numbers with different heights and different spreads. First, we present a new method for ranking generalized fuzzy numbers. The proposed method considers the defuzzified values, the heights and the spreads for ranking generalized fuzzy numbers. Based on the proposed method for ranking generalized fuzzy numbers, we propose a fuzzy Risk Analysis algorithm to deal with fuzzy Risk Analysis problems. The proposed method provides a useful way for handling the fuzzy Risk Analysis problems.

  • Fuzzy Risk Analysis based on the ranking of generalized trapezoidal fuzzy numbers
    Applied Intelligence, 2007
    Co-Authors: Shi-jay Chen, Shyiming Chen
    Abstract:

    In this paper, we present a new method for fuzzy Risk Analysis based on the ranking of generalized trapezoidal fuzzy numbers. The proposed method considers the centroid points and the standard deviations of generalized trapezoidal fuzzy numbers for ranking generalized trapezoidal fuzzy numbers. We also use an example to compare the ranking results of the proposed method with the existing centroid-index ranking methods. The proposed ranking method can overcome the drawbacks of the existing centroid-index ranking methods. Based on the proposed ranking method, we also present an algorithm to deal with fuzzy Risk Analysis problems. The proposed fuzzy Risk Analysis algorithm can overcome the drawbacks of the one we presented in [7].

  • a new method for ranking generalized fuzzy numbers for handling fuzzy Risk Analysis problems
    Joint International Conference on Information Sciences, 2006
    Co-Authors: Shyiming Chen, Jimho Chen
    Abstract:

    In this paper, we present a new method for ranking generalized fuzzy numbers for dealing with fuzzy Risk Analysis problems. The proposed method considers the defuzzified values, the heights and the spreads of generalized fuzzy numbers, simultaneously, for ranking generalized fuzzy numbers. It gets better ranking results to rank generalized fuzzy numbers than the existing methods. We also apply the proposed method to deal with fuzzy Risk Analysis problems. The proposed method provides a useful way for handling fuzzy Risk Analysis problems.
