3In queuing theory, which will be introduced in Chapter 6, L is used to denote the expected number of jobs in the process.

5Originally developed by Toyota, just-in-time (JIT) is now being used by many organizations around the world, including General Motors, Apple Computers, IBM, and others. JIT is mostly known for allowing companies to become more efficient by keeping low levels of inventory. However, JIT is more than just another inventory control system, because its underlying philosophy for managing operations influences all parts of a company.
6Integer programming is an optimization technique that allows decision problems to be modeled as a set of linear equations. There is one equation to model the objective function and one equation for each constraint in the problem. The solution method is based on solving a series of linear programming problems, which essentially allow for the decision variables to take on noninteger values.
