<P>PROBLEM TO BE SOLVED: To provide a supporting method for determining an optimal maintenance time by predicting a life of an objective facility, and to provide a computer program, and a supporting device that predicts a life of an objective facility so as to determine an optimal maintenance time thereof. Ž<P>SOLUTION: This supporting method includes a step 1 of estimating the number of repeating times of application of fluctuation stress at a bearing part on the basis of a time change of a power or a current of an electric motor in an objective facility and obtaining a consumption rate of a life so as to determine a remaining life, a step 2 of tracing a progress of a deteriorating condition by an exponentiation rule of a time change rate of a vibration speed obtained from a vibration sensor attached to the bearing part so as to estimate a time point of reaching a dangerous region, and a step 3 of determining a remaining life in accordance with the step 1 and step 2 in a late stage of a caution region on the basis of a result of vibration diagnosis in the step 2. In the step 3, the life of the objective facility is determined on the basis of the two time periods of the remaining life of the step 1 and step 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
