Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s) A 5 minus E 4 B B 6 minus F 5 B C 4 A G 11 C, E D 2 A H 6 D , F

The amount of minutes you were active during the day is referred to as activity.

It's essentially the total amount of time you spent exercising in a 24-h cycle, and it may be anything from a gym aerobic or prenatal yoga class to brisk strolling.

Time to complete the project: 21 weeks

Below are the Critical Paths: B - E - G ES, EF, LS, LF.

The calculation has been attached below.  

The earliest start is the latest of the predecessors' earliest finish times. The combination of the oldest start and endurance represents the earliest conclusion.

The latest finish is the earliest of the successors' latest start timings. The deviation between the newest finish and the length is the latest start.

The slack is the time between the earliest start (or finish) and the latest start (or complete) (or finish).

The beginning of the "Program Complete" task is termed the construction length. This (project duration) is regarded to be the most recent finish of the predecessors for the sake of computing slack. This (project duration) is regarded to be the most recent finish of the predecessors for the sake of computing slack.

The critical route is a set of jobs with no slack in between them.

Explanation:

The earliest start is the latest of the earliest finish times of the predecessors. The earliest finish is the sum of earliest start and duration.

The latest finish is the earliest of the latest start times of the successors. The latest start is the difference of latest finish and duration.

The slack is the difference between earliest start (or finish) and latest start (or finish).

Project duration is the earliest start of the "Project Done" task. For purposes of computing slack, this (project duration) is taken to be the latest finish of the immediate predecessors.

The critical path is the sequence of tasks with 0 slack.
