This new edition is focused on offering more problem solving hints and tips as part of the solution to most examples and solved problems throughout the book. New content changes include an increased coverage of sustainability. Each chapter has a new section that features information on how sustainability is impacting the topic of that chapter.

More coverage of technology and technology examples via operations and supply chain management as well as many new/current examples such as JIT and how the automotive industry/supply chain was disrupted from the Japan earthquake.
