ABSTRACT:
A system of preventive maintenance for plant component parts correlates parameters for determining the transition probability distribution of degradation phenomena, selects an arbitrary influencing factor with respect to each of various influencing factors of the degradation phenomena, selects one of the parameters for the transition probability distribution as a first function, and sets the transition probability distribution when the variables of various influencing factors are reference degree values of a reference system. The system computes a ratio between the first function and the parameter value in the reference system to give a function of the subdivided index of degradation of the influencing factor, multiplies the subdivided index of degradation of various influencing factors by a unit conversion and a coefficient for reliability.
