The invention relates to a dual-linear data coordinate method, which comprises: 1, based on the material relation diagram of mechanical factory, generating dual-linear data coordinate mode; 2, using variable eliminate method to decompose and normalize the coordinate mode; 3, based on decomposed and normalized mode, using micro particle group algorism, to obtain accurate material and component data. In said the invention, the priority value can be fixed easily, to treat the non-watched material speed and component variable easily, with high coordinate accuracy. And since the coordinate process is decomposed and normalized, and the search space of micro particle group algorism has reduced dimensions, the invention has high coordinate efficiency. And it uses the upper and lower limits of component variables, to confirm reliable coordinate result. The invention can be integrated with other systems.
