Part 1 of 1 - 15.0 PointsQuestion 1 of 121.25 PointsWhich maintenance downtime is expended as a result of waiting for a spare part to become available, waiting for necessary test equipment to perform maintenance, waiting for transportation, waiting to use a facility required for maintenance, and so on?A.Maintenance Downtime (MDT)B.Logistics Delay Time (LDT)C.Administrative Delay Time (ADT)D.None of the aboveAnswer Key: BQuestion 2 of 121.25 PointsWhich is the third step in the Corrective Maintenance Cycle (Figure 2.11)?A.ReassemblyB.Localization and IsolationC.Removal of Faulty ItemD.Preparation for MaintenanceAnswer Key: BQuestion 3 of 121.25 PointsWhich is the first step in the Preventive Maintenance Cycle, (Figure 2.17 - Composite view of uptime/downtime factors)?A.Active Maintenance TimeB.Checkout TimeC.Preparation TimeD.Preparation for MaintenanceAnswer Key: CQuestion 4 of 121.25 PointsOperational availability is the probability that a system or equipment, when used under stated conditions in an actual operational environment, will operate satisfactorily when called upon.A. TrueB. FalseAnswer Key: TrueQuestion 5 of 121.25 PointsWhich is not an availability factor?A.AchievedB.InherentC.FrequencyD.OperationalAnswer Key: CQuestion 6 of 121.25 PointsAvailability is a key measure of system performance, which in turn is a function of maintainability and reliability.A. TrueB. FalseAnswer Key: TrueQuestion 7 of 121.25 PointsThe frequency of maintenance will decrease as system reliability is degraded.A. TrueB. FalseAnswer Key: FalseQuestion 8 of 121.25 PointsWhen assuming negative exponential distribution, the failure rate is considered to be relatively inconstant during normal system operation if the system design is mature.A. TrueB. FalseAnswer Key: FalseQuestion 9 of 121.25 PointsThe act of diagnosing and repairing, or preventing system failures is known as detection.A. TrueB. FalseAnswer Key: FalseQuestion 10 of 121.25 PointsAdministrative Delay Time (ADT) refers to the total elasped time that is required to repair and restore a system to full operating capacity and or to retain a system in that condition.A. TrueB. FalseAnswer Key: FalseQuestion 11 of 121.25 PointsDefine reliability. What are its major characteristics?Reliability is a key position in a logistics system. This is the system producing as needed for an extended period time; this is a factor that is vital in keeping the system moving smooth. The different parts of the term reliability are availability in the term of the processes available to keep everything smooth. Maintainability in reference to the amount of efforts needed to maintain a certain level of operations. Many different factors go into the entire process, different levels and processes for maintenance and predicting the rate of downtime fall into the realm of reliability. It is a long and thorough process that requires a lot of attention. Question 12 of 121.25 PointsDefine maintainability and list some of its major characteristics.Maintainability falls into the same family as the previous question. Maintainability is a designed system focused on accuracy. If you looked at the entire process including all the measures of time as in personnel, maintenance, and support factors. These factors go into finding the maintainability of a system, the cost and effort to maintain a system and keep it producing as needed. Also included in this is corrective maintenance time as in the unscheduled time needed for a system failure. Preventative maintenance in planned scheduled maintenance like inspections and normal planned issues. All these play into the maintainability of a system.
