A New Model to Identify and Judge on System States of Large Scale Engineering Project

Abstract

The problem of identification and judgement on engineering project system state brings disadvantage to automatic analysis and diagnosis of engineering project implement states diagnosis system. In order to solve the problem, the engineering systematic state and its evolution mechanism is analyzed at first, and the inner relationship among information gain, Eulidean norm and systematic state change is found. Then, according to Lyapunov system stability theory, a new method to instant identify and judge by Euclidean norm to engineering project system state is put forward under the premise of information gain. The critical parameters that judge the system states under different norm values are determined with simulation test. Finally, the practicability and availability of the method has been proved with real engineering experiments.
