This is the first Indian book that shows applications of simple topics in Mathematics, ranging from linear functions, quadratic functions, concave and convex functions, sequences, combinatorial analysis to help Indian practicing manager in stating, defining, structuring, and resolving complex managerial problems. Extensive use of MS Excel is made to help the readers in carrying out complicated computations without any errors. The appendices at the end of chapters provide mathematical formulations for readers who wish to get into the details. Many real-life cases to sharpen the readers' skills in applying the ideas of Mathematics for analysis and resolution of unstructured problems are included.

Vasant Mote worked as a Planning Officer in Calico Mills Ahmedabad. He joined the Indian Institute of Management Ahmedabad (IIMA) in 1962 where he worked as a Professor until he retired in 1993. During his career in the Institute V. L. Mote took consulting assignments from many reputed Indian firms. His clients included among others Binny Ltd, The Gujarat Road Transport Corporation, Clarion Advertising Agency, Mumbai, and Arvind Mills.

T. Madhavan joined the Institute as an Assistant Professor and retired as a Professor in May 2003. After retirement, he served as Cat Centre Coordinator from 2003 to 2006. He continued as visiting faculty in the Indian Institute of Management Ahmedabad till May 2011. Applications of Mathematics for the betterment of life in the rural India is his major research interest.

I must commend Wiley on bringing out a very good book on Operations Research authored by Prof. Mote and Prof. Mahadevan. It is indeed a valuable resource for post graduate students and practitioners!”
