In this book the authors provide a fresh look at basic reliability and maintainability engineering techniques and management tools for application to the system maintenance planning and implementation process. The essential life-cycle reliability centered maintenance (ReM) activities are focused on maintenance planning and the prevention of failure. The premise is that more efficient, and therefore effective, life-cycle maintenance programs can be established using a well disciplined decision logic analysis process that addresses individual part failure modes, their consequences, and the actual preventive maintenance tasks. This premise and the techniques and tools described emphasize preventive, not corrective, maintenance.The authors also describe the techniques and tools fundamental to maintenance engineering. They provide an understanding of the interrelationships of the elements of a complete ReM program (which are applicable to any complex system or component and are not limited only to the aircraft industry). They describe special methodologies for improving the maintenance process. These include an on-condition maintenance (OeM) methodology to identify defects and potential deterioration which can determine what is needed as a maintenance action in order to prevent failure during use.Additionally, the authors describe an aircraft flight safety prediction model that can be used to facilitate application of the ReM analysis process. The model takes into account defects and failure mechanisms that may be introduced during production, storage, operation, and v vi Foreword maintenance. Standardized functional fault tree diagrams are presented which serve as templates to facilitate application or tailoring to specific systems or major components.This book can be a valuable reference document for continuous improvement of the system maintenance planning and implementation process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
