The Aerospace Industries Association (AIA) Rotor Integrity Sub-Committee (RISC) has proposed an enhanced damage tolerance design strategy for critical rotating parts intended to reduce the rate of uncontained rotor events. Building upon the industry committee’s experience in developing a probabilistic relative risk assessment methodology for hard alpha anomalies in titanium rotors, a similar probabilistic approach has been proposed for induced anomalies along machined hole surfaces in engine rotors. Key inputs to this strategy are the development of a surface anomaly distribution for machined holes and the benchmark of design target risk (DTR). The DTR is an FAA/industry agreed upon design target value of relative risk against which the results of the probabilistic risk assessment are compared.

Risk Assessment Methodology

Abstract As counterfeiting techniques and processes grow in sophistication, the methods needed to detect these parts must keep pace. This has the unfortunate effect of raising the costs associated with managing this risk. In order to ensure that the resources devoted to counterfeit detection are commensurate with the potential effects and likelihood of counterfeit part usage in a particular application, a risk based methodology has been adopted for testing of electrical, electronic, and electromechanical (EEE) parts by the SAE AS6171 set of standards. This paper provides an overview of the risk assessment methodology employed within AS6171 to determine the testing that should be utilized to manage the risk associated with the use of a part. A scenario is constructed as a case study to illustrate how multiple solutions exist to address the risk for a particular situation, and the choice of any specific test plan can be made on the basis of practical considerations, such as cost, time, or the availability of particular test equipment.

Risk Assessment Methodology

It is a challenge to prevent an occupational accident in any industrial activities. The aim of this study is to improve the safety and reduce the risk of occupational accidents at shipyard through developing a risk assessment. This paper describes the concept and methodology of risk assessment for occupational safety and its application. The methodology introduces an effective and useful assessment procedure to construct the database based on the past occupational accidents occurred at shipyards. Quantitative methodology is developed to understand the unsafe working conditions and environment at the shipyard by the convenient handheld to collect the data with Information Technology. Some examples of effective hazard countermeasures are suggested and a feasibility study is conducted to improve a walking environment at shipyards.
