Information from socio-economic analyses can serve not only to select between alternative risk management measures in the decision-making matrix but can identify the relevant timelines for implementation (e.g., resulting from process change, product reformulation or instillation of pollution abatement technology). In the case of authorisation, REACH specifies that socio-economic data will form a key variable in the identification of suitable alternatives and the period for granting an authorisation before it needs to be reviewed. 

To illustrate the essence of the asset-allocation problem, 1 begin with a simple example theit includes the following assets U.S. stocks, intemationeil stocks, U.S. bonds, international bonds, and cash. This constitutes a broad asset mix typical of that used by many professional managers. Expected returns are 11.0%, 12.6%, 6.0%, 6.9%, and 5.0%, respectively. The expected standard deviations (risk) of these returns are 12.5%, 14.7%, 4.3%, 7.8%, and 0.0%. Note that the standard deviation of cash returns is zero because this asset is presumed to consist of riskless U.S. Treasury securities. The correlation matrix for asset returns is ... 

The purpose of a risk management matrix is to (a) provide a logical framework for hazard analysis and risk assessment and (b) assist risk decision makers in arriving at their risk reduction and risk acceptance or declination conclusions. The implicit goal is to achieve acceptable risk levels. Several standards and guidelines now include the concepts of residual risk and acceptable or tolerable risk (e.g., ANSl/Bll TR3, ISO/IEC Guide 51, SEMI SIO—see references for full titles). 

In the following subsections, we will present some Markov chain properties required to hold in order to compute the MFPT values, provide formulas to compute the MFPT matrix of a Markov chain and discuss how detectability can be modeled for improving supply chain risk management. 

Firstly the chapter approaches risk management in a general sense, including the phases of risk assessment (risk identification, risk analysis and risk evaluation), risk control (risk reduction or mitigation, and risk acceptance), risk documentation and communication, and risk review. Then some methods for risk assessment are explored further, such as matrix type and Failure Mode Effect Analysis (FMEA) using risk priority numbers (RPN). 

To emphasize Safety professionals must understand that the definitions of terms for incident probability and severity and for risk levels vary greatly. Thus, they should tailor a risk assessment matrix to suit the hazards and risks and the management tolerance for risk with which they deal. Examples of the definitions used for incident probability and severity are presented here, as well as definitions for risk categories and risk assessment matrices. They are intended to provide safety professionals with a broad base of information from which choices can be made in developing the matrix considered appropriate for their clients needs. 

A general purpose of the flood risk management framework is providing a basis for rational decision making. Recording different variants with associated risks, costs, and benefits, in a matrix or decision tree serves as an aid for making decisions. 

A risk assessment matrix is a useful tool to identify the level of risk and the levels of management approval required for any Risk Management Plan. There are various forms of this matrix, but they all have a common objective to define the potential consequences or severity of the hazard versus the probability or likelihood of the hazard. 

The Hazard Risk Index (HRI) matrix is a risk management tool used by system safety for hazard/mishap risk assessment. The HRI matrix establishes the relative level of potential mishap risk presented by an individual hazard. By comparing the calculated qualitative severity and likelihood values for a hazard against the predefined criteria in the HRI matrix, a level of risk is... 

This chapter presented a disruption risk assessment method for managing the supply disruptions in a global supply chain. The assessment can help practitioners to quantify risks in their supply chains based on hazards, vulnerability, and risk management practices. The disruption risk scores of suppliers facilities and transportation links can lead a company to proactively manage its suppliers. They then can use the disruption risk matrix to visualize the relative risk of all idenfified hazards. We presented a case study of a global distribution company to illustrate the application of this framework in assessing disruption risks for facilities and transportation links. This framework can be used to develop a company disruption risk profile, which in turn can be used to identify the critical network components that are prone to disruptions and to prioritize the risk mitigation activities. 

Each process owner requires a defined level of decision authority. This authority level delineates the bounds of decision making granted by the organization to the process owner. Business needs and risk assessment must be incorporated into the design of the decision authority granted to a process owner. Table 6 is an example of a decision authority matrix design for a process owner. It requires cross-functional management support to be effective.
