Definition of Manufacturing System
We define a manufacturing system to be a collection of integrated equipment and human resources, whose function is to perform one or more processing and/or assembly operations onl, part, or set of parts.

Three functions: (1)Loading--involves moving the work units into
the production machine or processing equipment from a source inside the station. (2)Positioning--provides for the part to be in a known location and orientation relative to the workhead or tooling that performs the operation.
作业5：
most systems exhibit dynamic behavior on their way to (or sometimes even during) the steady state that may produce a deviation in performance from that computed by steady state analysis. Design and control of such systems (for example, multiechelon spare parts inventories, integrated manufacturing cells or computer/communication nets) involving explicit consideration of the cost or impact of transient behavior, is now a real possibility.
Human Resources
Human perform some or all of the value-added work that is accomplished on the parts or products.
Classification of Manufacturing System
② Three of the most important of these are widespread and inexpensive transportation systems, communication systems that provide real-time interaction between people in almost any part of the world, and computers that assist in the design, control, and analysis of complex activities.
Production machines
Manually operated production machines Semi-automated production machines Fully automated production machines
Material transport System
Type 1: Single Stations Type 2: Multi-Station Cells Type 3: Production Lines

2. 课外翻译（把下列语句翻译成中文）
① Flexible manufacturing systems (FMS) and computer /communication networks exemplify complex systems that fall into a class called discrete event stochastic systems (DESS). The efficient design and operation of these systems is extremely important to economic competitiveness, yet system behavior is not completely understood. Present methods of analysis and design of DESS focus on their behavior in the steady state, a conceptualization that requires performance measures to be made “in the long run” or “averaged over time.” Yet,
