The invention provides a method of diagnosing a system, a method of operating an aggregating system for system diagnosis and an aggregating system for system diagnosis, which are suitable for evaluating effectivness of system improvement. A total receiving steam amount Qi and a total necessary steam amount Qo are grasped. Further, a total amount of steam loss which can be solved by a predetermined system improvement is grasped as a total improvable steam loss amount. Then, based on these respective grasped total amounts, a ration of the total improvable steam loss mount relative to a total unknown steam amount Qx which is a difference between the total receiving steam amount Qi and the total necessary steam amount Qx is obtained as an improvable unknown steam ratio Kts. Or, the unknown steam ratio Kt and an improved unknown steam ratio Kxx or the unknown steam ratio Kx and an apparent improved unknown steam ratio Kxx' is/are obtained. |
