Discussion About Logic Decision Method of Maintenance Modes for Military Equipment

The choice of maintenance modes is a very important problem for laying down maintenance concept of military equipment.Maintenance modes can be divided into corrective maintenance, detective maintenance, time-based maintenance,condition-based maintenance, proactive maintenance and improvement maintenance.Applicability and validityof maintenance modes were discussed,and selection order of maintenance modes was analyzed.A new logic decision model of maintenance modes was put forward.The model was composed of three parts:the maintenance decision of non-functionally significant item(NFSI)and functionally significant item(FSI) which failure risk is acceptable,the preventive maintenance decision of FSI which failure risk is not acceptable,and the improvement maintenance decision of FSI.Compared with the logic decision models of MSG3 and RCM2,the logic decision method of maintenance modes is clear, simple and easy to use.
