The branch of engineering which focuses on the optimization of procedures, equipment and departmental budgets is known as maintenance engineering. It also focuses on improving the maintainability, availability and reliability of equipment. The primary purpose of maintenance engineering is to ensure that a particular unit is ready for use and maximize its availability while minimizing the costs. Some of the disciplines which contribute knowledge towards maintenance engineering are logistics, probability and statistics. There are numerous applications of this field such as analyzing repetitive equipment failures, forecasting spare parts, estimating repair costs and assessing the requirement for equipment replacements. This book elucidates the concepts and innovative models around prospective developments with respect to maintenance engineering. Some of the diverse topics covered in this book address the varied branches that fall under this category. Scientists and students actively engaged in this field will find this book full of crucial and unexplored concepts.
