Anotace:

Terms and definitions related to quality and reliability. Philosophy of quality and reliability. Basic quality control systems used worldwide: ISO 9000, Total Quality Management, Kaizen, Six Sigma, Lean, and Lean Six Sigma. Characteristics, principles, methods, and tools used in applications of these quality control systems. Other tools used in quality management systems: factorial experiments, Ishikawa's seven tools, seven new managerial tools, Taguchi's loss function, and quality function deployment. Analysis of failure modes and their effects, process capability. Statistical inspection. Basic concepts in reliability. Statistical distributions used in reliability, their characteristics, and applications. Reliability of components and systems; calculation of system reliability using the composition and decomposition method, the list method, and the minimum successful path method. Hot and cold backup, types of hot and cold backups. Reliability calculations associated with the use of these backups. Fault tree quantitative and qualitative analysis. The course aims to familiarize students with various quality systems and basic quality management tools and their use. Students will also gain a basic overview of the reliability issues and their solutions for individual components and for systems.
