The braking system on a vehicle has two major components both of which must function in order that the breaks will work as intended. Assuming that the first component has a reliability of 99.8%, and the second a reliability of 96.9%. If the second brake component in the system above is given a backup with reliability of 96.9%, then the overall reliability of the system will Select one: a. Increase b. decrease cremain unchanged d. none of the above The best strategy of minimizing the amount of safety Inventory to be kept in a store without hurting the level of customer service is Select one: a. minimizing the cycle service level b. minimizing the uncertainty inherent in supply creducing the supply lead time d. minimizing the uncertainty inherent in demand
