- In a project network, the critical path is the sequence of activities which has the Multiple Choice greatest variance. longest duration. most events. most activities.arrow_forwardTask C is directly preceded by two tasks–task A and task B. Task A has an expected task completion time of five weeks and an ES time of week 6. Task B has an expected task completion time of seven weeks and an ES time of week 7. Task C has an expected task completion time of 10 weeks. The ES for activity C is?arrow_forwardFor the activity on arrow network information given below (activity durations are givenin the table under part b): a. Compute the earliest event occurrence time (TEj), the latest allowable eventoccurrence time (TLj), and the event slack (ESj) for all nodes/events. b. Compute the four schedule dates (ESDij, EFDij, LSDij, LFDij) and the floats(TFij, FFij) for all activities.arrow_forward
- 11-16 Jean Walker is making plans for spring break at the beaches in Florida. In applying techniques she learned in her quantitative methods class, she has identified the activities that are necessary to prepare for her trip. The following table lists the activities and the immediate predecessors. Draw the network for this project. 11-17 The following are the activity times for the project in Problem 11-16. Find the earliest, latest, and slack times for each activity. Then find the critical path. These problems go together and are deterministic times.arrow_forward3. Compute the early, late, and slack times for the activities in the network that follows, assuming a time-constrained network. Which activities are critical? What is the time-constrained project duration? Note: Recall, in the schedule resource load chart the time-constrained scheduling interval (ES through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the project. Assume you have only three resources and you are using a computer that uses software that schedules projects by the parallel method and following heuristics. Schedule only one period at a time! Minimum slack Smallest duration Lowest identification number 282 Chapter 8 Scheduling Resources and Costs Keep a log of each activity change and update you make each period-e.g., period 0-1, 1-2, 2-3, etc. (Use a format similar to the one on page 259.) The log should include any changes or updates in ES and slack times each period, activities scheduled, and activities delayed. (Hint: Remember to…arrow_forwardDave 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.

Can you do it in excel format please Part 1 To prepare a Gantt chart for the FAO-funded Aquaponics Project in Barbados, we need to break down the project into individual tasks and then arrange them in a logical order based on their dependencies.

- 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: Time Activity (weeks) Dave's earliest start (ES) and earliest finish (EF) are: Dave's latest start (LS) and latest finish (LF) are: The slack times are: The activities on the critical path are The total project completion time for Dave = weeks. ▼ Time Immediate Activity (weeks) Predecessor(s) A 6 8 3 3 B C D A A Activity A B C D E F G H Activity H G F E D C B A Activity A B C D E F G H | E F 6 G ES □ 0 H 8 T П LS 15 14 8 9 12 11 0 5 Slack || EF 6 13 22 23 5 7 9 8 LF | | L | | Immediate Predecessor(s) B B C, E D,Farrow_forwardSuppose you are the project manager for the following project: First, draw a network diagram for the project. Determine the critical path and slack times for all of the tasks. This completes your plan for the project schedule. During project execution, you become aware of the need to change the duration of Task 4 to five days. Meanwhile, Task 3 has been finished one day early, so it only took one day to do. What, if any, effects do these changes have on your project? What would have happened if you had not been monitoring the status of the project?arrow_forwardCritical Path Method (CPM) helps project manager to plan all tasks that must be completed as part of a project. They act as the basis both for preparation of a schedule, and of resource planning. A further benefit of CPM is that it helps to identify the minimum length of time needed to complete a project.
