The Dynamic Research of Health Resources in Chongqing City Based on the Grey Majorized Model

Grey system theory is a new cross course by China famous scholar professor Deng Julong founded in 1982 . grey GM(1,1) model usually be used simulation and prediction of equidistant monitoring data sequent and gained a series of significant achievement in natural science and social science. But to non-equidistant and high growth data sequent, has to build the grey GM(1,1) model through equidistant treatment of non-equidistant data or to build directly non-equidistant grey model through complex transformation, and usually has larger lagging error. In time sequent [k,k+1] interval, in order to majorize and increase accuracy of background value z

(k+1), the area of [k,k+1] interval and GM(1,1) function curve envelope has been replaced by n small interval trapezoidal area. The GM(1,1) grey majorized model is built based on majorized grey model background value generally be used simulation and prediction of equidistant or non-equidistant and low or high growth data, this research puts to use Grey Majorized Model to analysis the tendency of the numbers of Chongqing health service expenditure, health revenue, the number of visits and health personnel, which may provide the base and reference for the development of Chongqing health plan.
