Problem #2 A contractor has six jobs awaiting processing at a workstation that is also a bottleneck and therefore is only capable of processing one job at a time. The day the job was received, its processing time and due date are given in the following table. It is now day 7. Day Job Job Processing Job Due Job was Received Time (days) Day A 29 B 15 37 1 WN D 25 E 32 43 Calculate the average throughput time and, for each job, the number of days overdue using the following priority sequencing rules: i. First-come-first-serve iii. Shortest processing time ii. Earliest due date Which rule should be used, in your opinion? Why? Problem #3 You are tasked with managing a project that has the following activities (time is given in weeks) and precedence relationships: Optimistic Most Likely Pessimistic Immediate Activity Time Time Time Predecessors A B C D B C, D a. Calculate the expected completion times for each of the project activities. b. Calculate the variance of the completion times for each of the project activities. c. Sketch the project activity network. d. Determine the project critical path. e. What is the expected project completion time? f. The project needs to be completed 12 weeks from now. What is the probability this deadline will be met
