Analysis of matchable problems based on system availability

With the growth of reliability,maintainability,supportability(RMS)engineering,the models of availability have been studied widely.However,the wave of the instantaneous availability did not get necessarily noticed.In this paper,the matchable problem generated by the interaction of subsystems of the new equipment is studied by analyzing the curve of the instantaneous availability within finite time,and some new concepts are presented for further study.The research frame and some major problems are also addressed.
