Operation Science Applied offers a fundamentally new approach to the management of operations. It does this by first recognizing that operations in manufacturing, health care, construction projects, restaurants, etc. share the same fundamental issues that must be addressed. These are demand, transformation, response time and whether to have inventory. What makes management difficult is the variability that affects all of these. The book is filled with case studies from the real world along with the analytics that show how to mitigate the corrupting influence of variability and succeed. Designed for advanced students and practicing professionals.
