本手册所要讨论的问题是系统工程问题,因而我们似乎有责任为“系统工程”一词下一个定义,以使读者可以由此知道,他通过阅读本手册将会学到什么知识。系统工程,因而也包括本书在内,所涉及的是一类特殊系统的设计问题。这类系统的特性,我们将在下面予以描述。据我们推想,阅读本书的读者所关心的可能是这类系统的设计或分析问题,因而我们在本书中所提供的材料,将使他有可能找到必要的理论和实践知识,从而对他的设计或分析工作会有所帮助。本 The issue to be discussed in this handbook is the issue of systems engineering, so it seems that we have a responsibility to define the term “systems engineering” so that readers will know what knowledge he will learn by reading this handbook. Systems engineering, and thus also this book, deals with the design of a particular type of system. The characteristics of such systems, we will describe below. To the best of our knowledge, readers of this book may be interested in the design or analysis of such systems, and the materials we provide in this book will make it possible for him to find the necessary theoretical and practical knowledge of him The design or analysis of the work will be helpful. this
