Milwaukee Paper Manufacturing had long delayed the expense of installing advanced computerized air pollution control equipment in its facility. But when the board of directors adopted a new proactive policy on sustainability, it did not just authorize the budget for the state-of-the-art equipment.
Draw the AON network for Milwaukee Paper, using the data in Example 1.APPROACH c In the AON approach, we denote each activity by a node. The lines, or arrows, represent the precedence relationships between the activities.
Draw the complete AOA project network for Milwaukee Paper’s problem.APPROACH c Using the data from Table 3.1 in Example 1, draw one activity at a time, starting with A.
Calculate the earliest start and finish times for the activities in the Milwaukee Paper Manufacturing project.APPROACH c Use Table 3.2, which contains the activity times. Complete the project network for the company’s project, along with the ES and EF values for all activities.
Calculate the latest start and finish times for each activity in Milwaukee Paper’s pollution project.APPROACH c Use Figure 3.10 as a beginning point. Overlay 1 of Figure 3.10 shows the complete project network for Milwaukee Paper, along with added LS and LF values for all activities. In what
Calculate the slack for the activities in the Milwaukee Paper project.APPROACH c Start with the data in Overlay 1 of Figure 3.10 in Example 5 and develop Table 3.3 one line at a time.
Show Milwaukee Paper’s critical path and find the project completion time.APPROACH c We use Table 3.3 and Overlay 3 of Figure 3.10. Overlay 3 of Figure 3.10 indicates that the total project completion time of 15 weeks corresponds to the longest path in the network. That path is Start-A-C-E-G-H in
Julie Ann Williams and the project management team at Milwaukee Paper want an expected time and variance for Activity F (Installing the Pollution Control System) where:a = 1 week, m = 2 weeks, b = 9 weeks APPROACH c Use Equations (3–6) and (3–7) to compute the expected time and variance for F.
Milwaukee Paper’s managers now wish to know the project’s variance and standard deviation.APPROACH c Because the activities are independent, we can add the variances of the activities on the critical path and then take the square root to determine the project’s standard deviation
Julie Ann Williams would like to find the probability that her project will be finished on or before the 16-week Earth Day deadline.APPROACH c To do so, she needs to determine the appropriate area under the normal curve. This is the area to the left of the 16th week.
Julie Ann Williams wants to find the due date that gives her company’s project a 99% chance of on-time completion.APPROACH c She first needs to compute the Z-value corresponding to 99%, as shown in Figure 3.14.Mathematically, this is similar to Example 10, except the unknown is now the due date
Suppose the plant manager at Milwaukee Paper Manufacturing has been given only 13 weeks (instead of 16 weeks) to install the new pollution control equipment. As you recall, the length of Julie Ann Williams’s critical path was 15 weeks, but she must now complete the project in 13 weeks.APPROACH c
