If the activity E took 16weeks instead of 12weeks to complete ,what impact will it have on the project duration?arrow_forwardIn one of the little-known battles of the Civil War, General Tecumseh Beauregard lost the Third Battle of Bull Run because his preparations were not complete when the enemy attacked. If the critical path method had been available, the general could have planned better. Suppose that the following planning network, with activity times in days, had been available: Determine the earliest and latest activity times and the activity slack for the network. Indicate the critical path and the time between the general’s receipt of battle orders and the onset of battle.arrow_forwardThe following estimates of activity times (in days) are available for a small project: Activity Optimistic Most Probable Pessimistic A 4 5.0 6 B 8 9.0 10 C 7 7.5 11 D 7 9.0 10 E 6 7.0 9 F 5 6.0 7 Compute the expected activity completion times and the variance for each activity.

- The Farmer's American Bank of Leesburg is planning to install a new computerized accounts system. Bank management has determined the activities required to complete the project, the precedence relationships of the activities, and activity time estimates, as shown in the following table. Use POM- QM to analyze this project. According to the result of POM-QM, the expected project completion time is (type number only, no text) Activity a b C d C f 8 k Activity Description Position recruiting System development System training Equipment training Manual system test Preliminary system changeover Computer-personnel interface Equipment modification Equipment testing System debugging and installation Equipment changeover Activity Predecessor a a b, c b, c d, e d, e h f.g a 5 3 4 5 I 1 3 Time Estimates (weeks) 1 1 2 5 m 8 12 7 8 I 4 6 2.5 1. 2 8 b 17 15 10 23 1 13 9 7 1 2 11arrow_forwardThe following is the data available for a project: Activity Predecessor Expected Duration (Days) A - 12 B A 9 C B,E 3 D - 10 E D 6 F E 3 G - 2 H G 9 I E,H 2 Expected duration for the completion of the project.

- QUESTION 7 The Stone River Textile Mill was inspected by OSHA and found to be in violation of a number of safety regulations. The OSHA inspectors ordered the mill to alter some existing machinery to make it safer (add safety guards, etc.); purchase some new machinery to replace older, dangerous machinery; and relocate some machinery to make safer passages and unobstructed entrances and exits. OSHA gave the mill only 35 weeks to make the changes; if the changes were not made by then, the mill would be fined $300,000. The mill determined the activities in a CPM/PERT network that would have to be completed and then estimated the indicated activity times, as shown in the following Table 6: Table 6 Activity Description A B с D E F G H I J K Activity Description Order new machinery Plan new physical layout Determine safety changes in existing machinery Receive equipment Hire new employees Make plant alterations Make changes in existing machinery Train new employees Install new machinery…arrow_forwardRedman Finance Services Inc. is interested to offer shared service expense reporting and processing services to a large multinational organization using an IaaS-SaaS-PaaS Model. Should the offer be accepted, following are the key activities to implement the project. What is the minimum number of weeks required for completing the project? What is the latest possible week that activity C may be started without delaying completion of the project? What is the computed slack time for activity D? Determine the latest finish time for activity E. Determine the latest time activity A can be started without delaying the project completion.arrow_forwardConsider the PERT network given below: 10 1-2-3 20 8-10-12 3-4-6 3-5-7 30 40 50 4-5-6 7-8-9 60 6-8-10 1-4-7 70 Determine the float of each activity and identify the critical path if the scheduled completion time for the project is 20 weeks.arrow_forward
