10.15 The Breakit Company manufactures anti-lock disk brakes (ABS) for use in auto- mobiles. An essential part of the manufacturing process is the factory assemble and integration linking (FAIL) system. Unfortunately this system has experienced num- erous failures over the years under a minimal repair concept that is a nonhomoge- neous Poisson process having an intensity function of p(t) = 1.15 x 10-713 with measured in operating hours. The system averages 2000 operating hours a year and is currently five years old. When the system fails, the repair time is lognormal with med = 6.2 hours and s = 1.2. (a) When the system was new, its manufacturer offered a 500-operating-hr warranty What is the system reliability during the warranty period? (b) What are the expected numbers of failures through the first five years of the system? (c) How many failures are expected in the next year (year 6 of the FAIL system)? (d) When the system fails, what percent of repairs will be completed within a single 8-hr shift? (e) When the system fails, it takes a crew of two to repair it. If the labor rate is $50 per hour and based upon the MTTR, what is the maintenance cost of the FAIL 10.15 The Breakit Company manufactures anti-lock disk brakes (ABS) for use in auto- mobiles.
