“…In the context of the risk matrix the value of risk is a discrete value, corresponding to the categories of consequence and likelihood: "IF frequency is "f"' category AND severity of consequences is "c" category THEN risk is "r" category" (Markowski and Mannan, 2008).…”

“…The event then covers several risk cells, and via a reverse fuzzy process a single risk indicator can be derived. Markowski and Mannan (2008) describe such a technique, where input on a continuous (quantified) scale can be transferred to a fuzzy risk matrix, but, unfortunately, the paper does not conclusively demonstrate how different levels of uncertainty in the input affect the process. Note that the uncertainty that can be expressed in the "fuzzy risk" will be lost in the reverse fuzzy process; the risk matrix cannot express uncertainty otherwise than by the width of its categories, as described in the previous paragraph.…”

Risk matrices are widely used in risk management. They are a regular feature in various risk management standards and guidelines and are also used as formal corporate risk acceptance criteria. It is only recently, however, that scientific publications have appeared that discuss the weaknesses of the risk matrix. The objective of this paper is to explore these weaknesses, and provide recommendations for the use and design of risk matrices. The paper reviews the few relevant publications and adds some observations of its own in order to emphasize existing recommendations and add some suggestions. The recommendations cover a range of issues, among them: the relation between coloring the risk matrix and the definition of risk and major hazard aversion; the qualitative, subjective assessment of likelihood and consequence; the scaling of the discrete likelihood and consequence categories; and the use of corporate risk matrix standards. Finally, it proposes a probability consequence diagram with continuous scales; providing, in some instances, an alternative to the risk matrix.

“…These parameters can be estimated using statistical method and calculations or by engineering judgment [3]. Risk assessment matrix gives both, objective and the subjective evaluation of risk and identifies risk acceptability for system [4]. Implementation of quantified scales to the risk assessment matrix axes has become an accepted practice and is supported by certain standards, which improved the decision making.…”

Abstract. Different industries have various residual risk levels for their rotating equipment. Accordingly the occurrence rate of the failures and associated failure consequences categories are different. Thus, a generalized risk matrix model is developed in this study which can fit various available risk matrix standards. This generalized risk matrix will be helpful to develop new risk matrix, to fit the required risk assessment scenario for rotating equipment. Power generation system was taken as case study. It was observed that eight subsystems were under risk. Only vibration monitor system was under high risk category, while remaining seven subsystems were under serious and medium risk categories.
