一、前言大系统是近二十年发展起来的一门新学科,七十年代以来发展特别迅速.已公开发表的论文在二千篇以上.大系统问题在国际上受到如此重视,主要由于近年来科学技术的发展,在工、农业和国防中规模庞大、结构复杂的系统日益增加,因此研究这类系统的正常运行以及改进它们的性能有很大实用意义。什么是大系统?目前没有明确的、普遍接受的定义.本文将就国外近几年研究的实际的大系统举几个例,借以说明大系统的一般特征.
I. INTRODUCTION The grand system is a new discipline developed in the past two decades and has been particularly rapidly developed since the 1970s. More than 2,000 papers have been published in the public domain. Major system problems have been so heavily regarded in the world, mainly because in recent years It is of great practical significance to study the normal operation of such systems and to improve their performance in terms of the development of science and technology and the large-scale and complicated systems in industry, agriculture and defense. What is a large system? There is no clear, generally accepted definition .This article will be foreign in recent years to study the actual large system to name a few examples to illustrate the general characteristics of large systems.
