Production Planning and Control is a key industrial engineering function for the manufacturing company and to comprehend these techniques and topics, it is essential to have the basic knowledge of the production functions and its scope. This book is prepared in such manner that even those who do not have much exposure to the function of production planning would be able to comprehend them, as they are related to industrial engineering. As the Planning Manager at Rallifan, heading the PP&C department, the author had the opportunity to introduce several PP&C systems and formats and with that experience, he was responsible to introduce similar systems and formats at Tanzania's National Bicycle Company right from its project stage. This experience has fully been utilised in bringing out this book on the basics of Production Planning. With all the case studies this book is expected to be of immense help not only to the engineering students, but also to practicing engineers who want to develop their career on production management. Special importance given to the fundamentals of statistics, so that the reader is fully equipped to understand better the vital topic of forecasting, which has a high bearing in statistics. Besides, exclusive chapters are devoted on related topics like Plant Layout, Scientific Inventory Control, Critical Path Method, Theory of Constraints etc. A unique feature of this book is that two chapters are devoted to explain the fundamentals of Industry 4.0 and the Internet of Things which are the latest buzz words reflecting advancement in Manufacturing Technology. This book is thus aptly titled Production Planning and Control: A Comprehensive Approach. Another feature of this book is that besides the syllabi, the university questions from several Indian and foreign Universities are compiled, classified chapter-wise and given at the end of each chapter as criteria questions, indicating the relevant paragraph number as a clue. This is expected to make the book highly examination oriented to the student besides being practical oriented to the PPC engineer.
