Question

Question;Multiple Choice: (select the most correct response)1. Average job completion time is:a.b.c.d.total processing time divided by the number of jobs.total flow time divided by the number of jobstotal flow time divided by total processing time.total flow time minus total late time.2. Work center loading:a. is done prior to detailed scheduling.b. does not incorporate a priority sequence rule.c. is the assignment and commitment of specific jobs to each work center for theplanning period.d. all of the above.3. When using the critical ratio (CR) priority sequence rule:a. a ratio of less than 1.0 implies that a job has a priority over a job with a ratio ofmore than 1.0.b. a ratio of more than 1.0 implies that a job has priority over a job with a ratio ofless than 1.0.c. the job with the earliest due date is scheduled first.d. none of the above.4. Which of the following is not a performance measure used in scheduling?a.b.c.d.job flow time.tardiness.labor capacity requirements.utilization.5. Gantt charts have several major limitations to include:a. the need to be updated regularly to account for new job arrivals and revised timeestimates.b. the inability to assess the relative work loads at each work center.c. the inability to serve as a foundation for the detailed scheduling function.d. the inability to signal the need for reallocation of labor and equipment to busierwork centers.6. Assume a task has the following times: a = 10, m = 25, and b = 40. Its expected time is:a.b.c.d.e.10254030none of the above.7. The critical path of a network is the:a.b.c.d.e.shortest time path through the network.path with the fewest activities.path with the most activities.longest time path through the network.none of the above.8. Given the following activitys optimistic, most likely, and pessimistic time estimates of 2, 10, and 20 days respectively, compute the PERT variance for thisactivity:a.b.c.d.e.36918none of the above.9. Managers use the network analysis of PERT and CPM to help them:a.b.c.d.derive flexibility by identifying noncritical activities.replan, reschedule, and reallocate resources such as manpower and finances.plan, schedule, monitor, and control large and complex projects.all of the above.10. In an activity-on-node (AON) network, the nodes represent______whereasthe arcs represent _________.a.b.c.d.activities, timeactivities, precedence relationshipsevents, activitiesprecedence relationships, timeTrue or False: (select the one correct response)11. A job shop is a firm that specializes in medium- to large-volume productionand utilizes line or continuous processes.TRUEFALSE12. The gantt chart (for loading) shows the order in which each job will be processed at each work center.TRUEFALSE13. Earliest due date (EDD) is a priority sequencing rule that states the job requiring the shortest processing time is the next job to be processed.TRUEFALSE14. Dispatching is the assignment and commitment of incoming jobs to one ormore specific work centers, for the day or week.TRUEFALSE15. The DDATE priority sequence rule will always minimize average job lateness.TRUEFALSE16. The gantt chart (for loading) provides the basis for the promised date of thejob to the customer.TRUEFALSE17. The assignment algorithm is an alternative method for performing the loading function in a job shop.TRUEFALSE18. The gantt chart (for supplementary scheduling) allows management tomonitor the progress of all jobs in the system in real time.TRUEFALSE19. Activities on the critical path exhibit positive slack times.TRUEFALSE20. The variance of project completion time equals the variances of all activitiesin the project.TRUEFALSE21. The expected activity time is the average of an activitys optimistic and pessi-mistic times.TRUEFALSE22. Dummy activities are found in activity-on-arc (AOA) convention PERT/CPM network models.TRUEFALSE23. The dummy activity has an expected time of zero by definition.TRUEFALSE24. Early start time (ES) is computed from right to left (backward pass).TRUEFALSE25. The project-group approach extends little or no formal authority to theproject coordinator.TRUEFALSEPRACTICAL PROBLEMS26.
