For improving the method of finding maintenance windows under uncertain parameters, an algorithm
of maintenance window under uncertainties is presented using interval analysis and sensitivity analysis. Age
replacement model is selected to demonstrate how to use this new algorithm. Considered the uncertainties, the
optimal maintenance interval of preventive maintenance is not only a single value, but a possible range. The
requirement from maintenance engineers is also considered, the maintenance window is made as a symmetrical
interval format, like (100 ± 10) day. Comparing with the methods using in the literatures, the new algorithm is
without requirement of distribution assumption of uncertain parameter values and computer simulation.
