The research of tractor reliability based on nonhomogeneous Poisson process

By tracking the experimentation of tractor operation, we obtained the data of the tractor failure, and used the nonhomogeneous Poisson process to establish the model of tractor failure process. Moreover, we estimated the parameter of the model by the networks method. At last, discussed are the correlation of the improvement or countermarch and failure intensity function. The failure intensity curve in the initial stages of tractor operation was mapped, which may estimate mean time between failures.
