Chapter 6 - Risk Management

Abstract

This chapter deals with risk management. Risk management is a very important aspect of maintaining safety at an acceptable level in service. It describes a control process that is based on changes in inspection approaches and periods. The probability of an unsafe state is the ‘‘measure of safety’’ that is the basis for the design to explicit safety constraints. Uncertainty affects risk management and originates with the need to make decisions with less than perfect data, especially in an environment of innovation. The short-term correction, if a safety issue is involved, can be handled through the risk management process. However, the long-term influence on general validity must be included in the ‘‘regulations'’ in terms of procedures required for demonstration of compliance. Finally, when service data are used to update knowledge and reduce uncertainty, inspection methods and periods can be used as the means of a control process to maintain safety in service.
