Establishment of the New Solution for Complex Systems in Multidisciplinary Science Proven by System Analysis Theory and Simulator

This paper establishes a very important scientific solution to science of complexity for physicists, and
presents a multidisciplinary involved physics and engineering. The innovative solution for complex
systems presented here is verified on the basis of principles in engineering such as feedback-system
analysis using the classical control theory. This paper proposes that a complex system is a closedloop
system with a negative feedback element and is a solvable problem. A complex system can be
analyzed using the system analysis theory in control engineering, and its behavior can be realized
using a specially designed simulator.
