Chapter 14 entitled 'JIT and lean operations' deal with operation system in which materials are moved through the system and services are delivered with precise timing so that they are delivered at each step of the process just as they are needed - hence the name just-in-time. | JIT and Lean Operations McGraw-Hill/Irwin Copyright © 2012 by The McGraw-Hill Companies, Inc.
