Analytic hierarchy process (Referred to as AHP), is a famous professor of operational research, Thomas saaty in the 1970 s, put forward a new decision-making method, has been widely used in the field of decision sciences. In 1996, in such a situation, professor saaty fully considering the elements or elements with the mutual influence between adjacent levels, through direct dominance and indirect dominance constructing comparative matrix, combining multiple matrix eigenvector build super matrix and the solution is empowerment, finally get the dominance of each element, put forward the optimization method of layer analysis method (AHP)Network analytic Hierarchy Process (ANP) network analytic hierarchy Process (Referred to asANP) network analytic hierarchy process (ANP)
