Determination of the Modified Periodic Inspection Policy Using Nonparametric Appoximation

비모수적 근사를 이용한 수정된 정기검사정책의 결정

A modified periodic inspection policy is examined. It is troublesome to know the life distribution and burdensome to compute an optimum planned inspection time numerically as well. A nonparametric a, pp.oximation is used so that equations for the optimum inspection time are expressed as closed forms. To show that the a, pp.oximation can be used in practice, simulations are conducted in the case of Weibull failure times.
