The benefit relationship matrix and influence relationship matrix among the strategy planning elements are set up.

The method of influence coefficient matrix which is successfully used in the Sino UK project of the Riv.

This paper gives derivations of two simple methods to calculate Jacobian matrixes of parallel mechanisms firstly: one is based on generalized inverse matrix of influenced coefficient matrix and the other is based on the velocity expressions between active joints and passive joints.

This paper offers a improved Hestense SVD method, and applies it in Parallel robot influenced coefficient matrix processing, therefore,the parallel robot real-time information processing ability is improved

The results obtained by the non-linear programming method are in agreement with those by the influence matrix method.

This paper gives the example using cable-stayed bend bridge with minimum radius in China,offsetting unclosed state by influence matrix and iterative method.

An efficient computational method of the influence matrix is proposed for cable force optimi-zation so as to calculate the cable force of cable-stayed bridges under dead loads easily.

Application of BP neural network in the effect matrix of flatness control;

By using the effect matrix,the nonlinear earthquake response of bridges under multi-support excitation is discussed in this paper.

In the nonlinear respondense analysis of bridges under multi support excitation,the effect matrix and Wilson θ method are used.

A concept of system effective matrix is presented, and subsequently, a new method-effective matrix based diagnosis is given.
