Preface to the First Edition....There has been lot of progress in industry. However, India has not been able
to establish in the Reliability Engineering field due to sellers market conditions.Manufacturers have been able to sell products of whatever quality and reliabilitythey make.
Now, the situation is changing to competitive market as customer expectationis for goods of better quality and reliability. The quality and reliable goods areneed of the hour for company survival. Application of reliability engineeringconcepts leads to better firm survival. The quality and reliability is built in theproduct by the involvement of all the departments of the company including topmanagement. In view of this, working knowledge of basic concepts and reliabilityengineering practice is necessary for all executives, production supervisors,sales and personnel.
This book covers all essential quality control techniques needed for designers,engineers, manufacturing plants and service sectors. It gives details of qualityconcepts, control on purchased product, manufacturing quality, qualitymanagement, human factor in quality, control charts, defects diagnosis andprevention, quality standards, total quality management, just-in-time and Taguchimethod. Further, it also covers reliability, production planning and control,maintenance functions, general maintenance, predictive maintenance, spare partsmanagement, Pareto principle, SWOT analysis and value engineering.
Appendices cover reliability terms, quality management terms, qualityassurance terms, maintenance terms, various standards, normal distribution,cumulative Poisson probabilities and two model question papers.
Authors are very thankful to JSS Academy of Technical Education, Noidafor their encouragement leading to such contributions. Authors also appreciatecooperation and helps extended by Mrs. Ranjana Pandey, Mrs. Parul Aneja,relatives and friends.
