Function partitioning algorithm of maintenance equipment based on occasion failure rate

Function partitioning of maintenance equipment is studied based on the fact that failure rates are different in different usage conditions. With the consideration of the types, usage occasion and volume of maintenance equipment, an assigning model from maintenance device to maintenance equipment is built for the failure rate in main occasion of maintenance equipment. The maintenance devices can be initially assigned to maintenance equipment by its main usage occasion without consideration of volume limitation, and the assigning correction of maintenance devices is conducted based on the difference between occasion failure rates with the consideration of volume limitation. An assigning algorithm of two maintenance equipment is proposed, and an example is given, which proved the model and solution algorithm are scientific.
