XI-R21: S&RA
Safety and Reliability Analysis

Short description

Objectives

The course aims to provide:

Knowledge: The course shall give a thorough introduction to basic concepts and approaches related to analysis and evaluation of safety and reliability of technical equipment – with a special focus on equipment that is used for production and distribution of energy.

Skills: The attendees shall be able to identify and assess failures of single units and of complex systems. They shall be able to assess which parts of a system that are of special importance to prevent system failures. They shall further be able to apply different methods to determine the reliability of single items and complex systems, and identify the pros and cons related to each method.

General competence: The attendees shall learn to understand the importance of safety and reliability in relation to applications within production assurance, quality, risk, environmental protection, and sustainable development. They shall, in addition, gain an understanding of the relationship between costs/disadvantages and benefits related to different safety measures.

Target Attendees / Participants

The course is dedicated to:

• professionals (engineers, managers, inspectors, legislators, …) who wish to deepen their knowledge in the field of risk based inspection
• other professionals dealing with risk and safety in industry
• individuals with no previous experience in the field of risk based inspection, but willing to extend their knowledge and take up new roles in this field within their companies
• university students of Steinbeis European Master Program in Risk Engineering and Management, and similar programs.

Definition and discussion of basic concepts related to reliability and risk analysis. Functional analysis and identification and evaluation of faults and hazards. System analysis based on FMECA, reliability block diagrams and fault trees. Quantification of reliability and availability of technological systems. Measures for reliability importance. Analysis of repairable systems by Markov methods. Analysis of safety-critical systems (IEC 61508). Analysis of systems with common cause failures. Estimation of failure rates. Survey of reliability data sources.

Teaching Methods

The basic theoretical contents of the course are presented in lectures these days. Small exercises and group works are used to get familiar with the concepts. The remaining part of the course is based on self-study with supervision from the professor by email. There are mandatory exercises to be conducted as part of the self-study.
