%X This research investigates the spare parts demand law of an aviation engine under certain maintenance policy,which is combined with period maintenance policy and failure replacement policy. The life time of unit is assumed to follow general distribution that is represented by Phase-Type(PH) distribution according to the dense properties of PH distribution;and a simulation algorithm is designed to obtain the unit replacement time series.Then using the EM algorithm,the spare parts demand point process of sing...
