Title: SYSTEM UPGRADE ASSESSMENT METHOD BASED ON SYSTEM PARAMETER CORRELATION COEFFICIENTS
Abstract:
A system upgrade assessment method based on system parameter correlation coefficients. Solved is the problem of a prior system upgrade assessment method that an accurate assessment cannot be performed on an upgraded system. For such purpose, the system upgrade assessment method comprises the following steps: acquiring first data of multiple parameters before a system is upgraded (S110); acquiring second data of the multiple parameters after the system is upgraded (S120); calculating a first correlation coefficient between each piece of the first data and a second correlation coefficient between each piece of the second data (S130); calculating a third correlation coefficient between each piece of the first data and a corresponding piece of the second data (S140); and determining, on the basis of the sizes of the first correlation coefficient, of the second correlation coefficient, and of the third correlation coefficient, whether the system is successfully upgraded (S150). The system upgrade assessment method allows, by comparing the correlation coefficients of the system parameters before and after the upgrade, accurate determination of whether the system is successfully upgraded.
