In this work: reliability of mechanical, electrical and welded joints has been discussed; parameters, which affect reliability directly or indirectly, have been included; and, importance of computers in reliability and maintenance has also been discussed. On the other hand, maintenance is the act of optimizing the available resources of manpower, materials, tools out test equipments etc. to keep the organizations in the healthy position at minimum cost. To meet out the challenges of the modernized and sophisticated equipments/machineries, it is desired to keep the system operative for a longer period. Therefore, the need to educate engineering graduates regarding all aspects of maintenance has become essential. Here attempt has been made to include all aspects of maintenance with the newer ideas of condition-based maintenance. In 21 chapters of this book, attention has been focused to include all important features of reliability and maintenance. This book will be useful to practicing engineers as well as to undergraduate students.
