What is System?

System dynamics approach is to understand the behavior of complex systems over time. It deals with internal reactions and seminars time delays that affect the behavior of the entire system. What makes it different from the dynamics of the use of other approaches to study complex systems is the use of feedback, seminars and stocks and flows. These elements help describe how even seemingly simple systems offer non-linear puzzlement.



The dynamics of the system is a powerful methodology for modeling and simulation software for the way in the formulation and understanding and discuss issues and complex problems. Originally developed in the 1950s to help corporate managers and improve their understanding of industrial processes, the dynamics of the system currently being used throughout the public sector and the private sector for policy analysis and design.



The dynamics of the system is the aspect of the theory of systems as a way to understand the dynamic behavior of complex systems. On the basis of the way is the recognition that the structure of any system - many of the circular, complex and sometimes late in the relations between its components - often no less important in determining the conduct of the individual elements themselves. For example, the theory of chaos and social dynamics. It also claimed that in many cases because there is full ownership of the importance that can not be found among the elements of the property, in some cases, the behavior of the whole can not be explained in terms of the behavior of the parts.



The dynamics of the system established in the mid-1950s by Professor Jay Forrester from the Massachusetts Institute of Technology. In 1956, Forrester accepted the professorship at the Massachusetts Institute of Technology, recently formed to manage the school. His initial goal was to determine how his background in science, engineering and can be accessed through the impasse, in a useful way for some, the key issues that determine the success or failure of companies. Forrester 's light on the common ground upon which the engineering and management, which led to the establishment of a system of dynamics, were to a large extent, through its involvement with managers at General Electric in the mid-1950s. At that time, GE managers wiser because of local employment and plants at their meeting in the state of Kentucky introduced a large three-year cycle. Business cycle and the sentence is not enough to explain the instability of employment. At the same time simulation (or accounts) stripped of the flow of information between the structure of General Electric factories, companies, including decision-making structure of employment and layoffs, Forrester was able to show how the stability of employment in General Electric and was scheduled internal organizational structure of the company , And not an outside force such as the business cycle. Simulating That was the beginning of the field dynamics of the system.
