- Consider a construction project with the following data on precedence relationships, durations, and costs: Activity Immediate predeccessor (s) Normal Time (days) Normal Cost ($) Crash Time (Days) Crash Cost ($) A - 6 120 4 170 B - 4 120 2 220 C A 3 195 2 270 D A 4 320 2 520 E B, C 7 700 4 1075 F D, E 5 650 2 1100 G E 10 1600 6 2300 F and G are the terminal activities of the project. (a) Find the critical path. (b) Find the project completion time and the corresponding cost. (c) Suppose it is required to complete the project in 22 days. Find which activities to crash and by how much, to yield the minimum project cost. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.I need assistance with the following questions in: Project Scheduling. This is a follow up to a question answered earlier. Question 1) was answered. 1) A company decides to plan a project, with activities, precedences and deterministic durations given in the following table: Activity i Duration (days) Immediate Predecessors A 32 none B 21 none C 30 none D 45 A E 26 A, B F 28 C G 20 E, F 2) The company decided that the project in the previous problem has to be expedited in order to optimize (minimize) the project cost. Expediting can be used to trade direct cost for indirect cost, since expediting the project reduces the indirect cost of the project by a fixed amount per day, while expediting an activity increases its total direct cost. The Accounting Department found that indirect costs amount to $100 per day, while activity direct costs as well as their normal and expedited times are given in the table below.…A project is scheduled to complete in six months duration. There are two activities in the project. The actual cost of Activity 1 is SAR 300,000 and that of Activity 2 is SAR 200,000. The planned value of these activities is SAR 280,000 and 150,000 respectively. On reviewing, the current project status is Activity 1 is 100% completed and Activity 2 is only 75% completed. (i) Perform the earned value calculations of the above project scenario and fill the given table. Activity Month 1 Earned Value Planned Value Actual Cost Cost Variance Scheduled Variance Cost performance Index Schedule performance Index (ii) What do you infer about the project schedule and cost based on your calculations?
- . True/False Statements (Tick the correct option) Selection of the critical path in network activity diagram for any project, is always focused onresult of the minimum time duration of the critical activities [ True / False ] Suppose, we have total 03 activities in the project “X”; namely L, M and N respectively. An activity “M” is the immediate successor of the activity “L”, while the activity “M” is the immediate predecessor for the activity “N”. According to this scenario, an activity “M” will be the last activity of the project “X” in the network activity diagram [True / False ] The dummy activity consumes both time and resources [True / False ] Towards the optimal solution through stepping stone method, when degeneracy problem is occurred, the next step is to focus on searching lowest value on the independent position in a non-allocated cells [True / False ] Hungarian algorithm, first convert any given assignment matrix into row reduction matrix [True / FalseProject Management In the below Precedence Diagram ( The activities durations are in weeks ) If the project manager wants to add extra (two) weeks for activity ( F ) and (three) weeks just in case other tasks may slip the schedule. Q: Show the impact of these provisions on the network diagram and recalculate the total project duration.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.

When is the earliest project completion?2. Which activities are critical (should not be delayed)?3. Which activities are noncritical (can be delayed)?4. How long can each of the activities be delayed without delaying the wholeproject (maximum slack)?A project consisting of eight activities satisfies the following precedence constraints:Time ImmediateActivity (weeks) PredecessorsA 3B 5AC 1AD 4 B, CE 3BF 3 E, DG 2FH 4 E, Da. Construct a network for this project. (You should need only one pseudoactivity.)You have collected the data for a Time-Cost CPM Scheduling model analysis. The time is in days and the project "direct costs" are given below. Immediate Normal Crash Normal Crash Activity Predecessor Time Time Cost (Direct) Cost (Direct) A None 3 2 $300 $408 B A 3 3 $100 $100 C A 1 1 $200 $200 D B and C 3 2 $400 $550 E D 2 1 $500 $900 F E 3 3 $200 $200 G F 2 2 $200 $200 The indirect costs for the project are determined on a daily duration basis. If the project lasts 16 days the total indirect costs are $408, 15 days they will be $350, 14 days they will be $200, and 13 days they will be $100. If you crash this project by one day what is the total (i.e., direct and indirect) project cost?
