本文选自“Systems Engineering:Methodology and Applica—tions”(New York,IEEE,1977)一书的第一篇前三节(第四节《有关因素的确定:问题说明,价值系统设计和系统综合》从略)。文中介绍了系统工程方法论及其应用,指出了系统工程的必要性和定义,讨论了系统工程教育和培训要点,描述了系统工程的任务矩阵。该书第二篇文章《从工程观点看系统工程》译文将载于本刊第12期。 This article is taken from the first three chapters of “Systems Engineering: Methodology and Applications” (New York, IEEE, 1977) (Section IV: “Determining Relevant Factors: Problem Descriptions, Value System Design and System Synthesis” slightly). This paper introduces system engineering methodology and its application, points out the necessity and definition of system engineering, discusses the essentials of system engineering education and training, and describes the task matrix of system engineering. The second article in the book, “Systems Engineering from a Engineering Perspective,” will be published in Issue 12.
