A collaborative multi-criteria decision making technique for risk factor prioritization

Organizations are a collection of individuals, and often a disastrous organizational accident involves contributions from several technical/environmental factors and actors throughout the system over time. This paper illustrates the efficiency of a new collaborative decision making technique that could assist a group of executive decision makers in identifying, analyzing, evaluating and prioritizing significant organizational system risks. The results from the collaborative technique when applied to real world risk intensive situations, such as aviation safety risk management, are compared with those obtained by using existing notable techniques. For the case examples shown, the number of expert judgments is reduced by up to 80%. Advantages and limitations of the proposed modeling approach for collaborative decision making are discussed.
