Flett's rich experience in electronic computer technology and excellent contribution，It provides an important foundation for the practical process of system dynamics。In the 19450s，He undertaken the stability and control analyzer (ASCA) project，It aims to develop a flight simulator to test the new aircraft design。He originally planned to use this idea as an analog computer，But he realized that the simulation component cannot meet the requirements of the plan simulator。So，He learned the digital calculation through P. Crawford，Then I visited the calculation center of the Moore Electrical Engineering College of Harvard University and the University of Pennsylvania，Where is the world's first universal computer ENIAC。These visits make Fredster confident，ASCA project bet365 best casino games will be based on digital calculation。This is a bold decision。

But，Digital computers at that time were too slow，Unable to meet the requirements of ASCA。Foraster, as the director，Leading the development of a Whirlwind Computer。For many years，Whirlwind is the only machine that is enough to simulate a complex power system such as aircraft。Later，Whirlwind becomes the core element of the semi -automatic ground air defense (SAGE) system，and become the first computer to produce。Computer memory has become the main bottleneck in the development of whirlwind very early，Foraster invented the magnetic core memory in 1949，Electrical and Electronic Engineers Association (IEEE) also awarded him with honor medal in 1972。

Foraster thought in the mid -1950s，"The pioneering era in the computer field has ended"，I constantly seek new fields and new challenges。He is in the servo institution、Digital computing and SAGE work，Provides rich experience for the management of complex organizations and large high -tech projects。1956，He joined the School of Management，and start considering the contribution of digital computing and control theory to management。

　　Feedback control theory and complex system modeling

System dynamics was originally called industrial dynamics，Research on the dynamic mode of the behavior of industrial organizations changes over time，Its generation and development of the United States have attached great importance to the study of military systems since the 1940s，and the four foundations established therefore (information feedback system theory、Knowing the process of decision -making formulation、Experimental model method of researching Bet365 app download complex systems、Digital computers can be used as a means to simulate the actual process))。It can be said，These four foundations are that the system dynamics can later be in industry、The key to the important impact of an important impact in the enterprise field。

Automated innovation of the control system，Promote the turnaround tactical decision in military activities to turn more forward -looking and predictive strategic design。Before the 1950s，Drawing of the target in military operations、Evaluation of enemy threats and other automated decisions cannot rely on human beings to get better solutions。With the development of control theory，Modern military operations far beyond the reaction ability of human organizations，Automated decision -making process is gradually implemented and promoted in military operations。After World War II，Accelerate the process of industrialization in the United States，People are inspired by the decision -making process in military activities，The formula -based decision -making research quickly moves from the military department to the civil authority。

Before that，The theory of the servo institution that started in World War II，It has strengthened people's understanding of the information feedback system。The structure of the system indicates the complex connection between the elements，The information in circulation is used as a new input and re -loop，will pass positive、The effect of negative feedback is enhanced or weakened。In this process，It is often accompanied by some information delay，Make the dynamic behavior of the system more diverse。Due to business and military Bet365 app download needs，The design and theoretical research on the information feedback system has developed rapidly。But，The human activity system continues to highlight the pursuit of human value，The adaptation and transformation activities of the environment with this becomes more diversified，The overall behavior of the system becomes more and more unclear。plus information feedback process is becoming more and more important in industry and business，People urgently need to produce production in related fields、Transportation、Sales and other links to analyze and predict behavior prediction。

　　Study on System Science Theory and Discipline

System dynamics research is when the system changes over time，Its structure、How does the function and behavior change change。So，System dynamic generation，Not only absorbing information in the theory of control and information、Feedback、Control and other concepts and thoughts，More importantly, the concept of system theory on general system theory、Principles、Thoughts and methods。Under the promotion of interdisciplinary research，Various systems and methods are becoming mature，System ideas with overall theory as the core becomes more and more important in complex system management and application system ideas。

early 20th century，Mechanical repayment theory still occupies a dominant position in scientific development。It is trying to explain all disciplines in physics，This scientific unified theory has been respected by some scientists and philosophers。Upgraded with the theory between mechanics and vitality theoreticals，People are aware of the unlikely restoration of life.。A. Whitehead (A. Whitehead) proposed in the book bet365 Play online games "Science and Modern World" in 1925，Use machine theory to replace mechanical decision theory。This pioneering view provides important theoretical support for the research on the open system for L. Bertalanffy，Especially his system integrity、Organic、Dynamic、Opinion and other views，The basis for becoming a research of general system theory。Now，Scholars generally think，The scientific theory of modern systems began in the related research work of Betrangfei。

System dynamics absorbs the important concept of the early stage of system science、Principles and methodology results。For example，Open System、The structure and function of the system、The relationship between behavior, etc.，Lile the general systemology foundation for system dynamics。Virgin Control theory and the generation of Shennong information theory，Research on servo institutions with information feedback as the main feature。System、Public、Structure、Relationship、Function、Behavior、Information、Feedback、Openness、Non -linear and other concepts and thoughts，Not only reflects the core point of view of system scientific theory，The basic principles of becoming a scholar study the relationship between complex systems and their interaction between the environment，and also provides support for scientific theory for system dynamics。The main idea of ​​system science is operating、System analysis and system engineering and other methodology have been promoted and applied，Especially after World War II and its practice, it was successful。This overall way of thinking，Start solving the problem of complex human activities for managers，Provided a new choice。

Bet365 app download The rise of interdisciplinary research，Expand the scope of application of system theory。As Betrangfei expects，He aims to be biological、The concept of the system proposed in the disciplines of physics、Thought、Principles、Methodism, etc. Summary，and promote it to a more general system，The general principles followed by the systematic behavior centered on mutual relationships。Interdisciplinary studies have become one of the important means of complex non -linear relationships and uncertain behaviors in human systems in the social system。Because the composition elements we face are more and more，The interrelationship between the elements is closer and complicated，and the input and output between the system and the environment form a intricate interactive network，At the same time, due to the limited nature of human cognitive level，We can no longer rely on a simple combination of a certain field or a few fields to understand and handle the complexity of the system。Research on interdisciplinary research breaks the unpopular barriers between different disciplines。It is trying to integrate a variety of disciplines to achieve a more global goal，This will challenge the scientific community and the paradigm it they follow。As one of the important methods of system scientific research，Interdisciplinary research has always run through the development of system science。System dynamics is the systematic theory、Control theory、Information theory、Electronic Computer Technology、Management、The results of interdisciplinary research such as system engineering。
