In the age-based maintenance policy, the goal is to minimize the following cost rate by finding the best value of t. Minimize: C(7) = C,F(7)+c,R(7) (5.1) r(t)dt Where T= Maintenance interval, decision variable R(t)= reliability function F(t), f(t)= cumulative distribution and probability density functions CF production loss in a failure replacement Cp= production loss in a planned replacement Do the following 1) Given R(t) = exp(-(1.51)), estimate C(t) given t=2. 2) Given R(t) = exp(), estimate C(t) given t=3. 3) Given R(t)= exp(-+-), based on equation (5.1), find the optimal t that minimizes C(T).
