An Integrated Approach to Product Development

Reliability Engineering presents an integrated approach to the design, engineering, and management of reliability activities throughout the life cycle of a product, including concept, research and development, design, manufacturing, assembly, sales, and service. Containing illustrative guides that include worked problems, numerical examples, homework problems, a solutions manual, and class-tested materials, it demonstrates to product development and manufacturing professionals how to distribute key reliability practices throughout an organization.

The authors explain how to integrate reliability methods and techniques in the Six Sigma process and Design for Six Sigma (DFSS). They also discuss relationships between warranty and reliability, as well as legal and liability issues. Other topics covered include:

• Reliability engineering in the 21^st Century
• Probability life distributions for reliability analysis
• Process control and process capability
• Failure modes, mechanisms, and effects analysis
• Health monitoring and prognostics
• Reliability tests and reliability estimation

Reliability Engineering provides a comprehensive list of references on the topics covered in each chapter. It is an invaluable resource for those interested in gaining fundamental knowledge of the practical aspects of reliability in design, manufacturing, and testing. In addition, it is useful for implementation and management of reliability programs.

Preface

Humans have come to depend on engineered systems to perform their daily tasks. From homes and offices to cars and cell phones, the context in which we live our lives has been largely constructed by engineers who have designed systems and brought their ideas to the marketplace.

While engineered systems have many benefits, they also present risks. How do we know that a building is safe and reliable? How do we know that a sensor in a train will work? How do we know that airbags and brakes will function in an emergency? No matter how many experts were involved in designing systems, the chance for failure always lingers. Thus, all engineering disciplines need reliability.
