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.…The estimated times and immediate predecessors for the activities in a project at Howard Umrah's retinal scanning company are given in the following table.

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 / False

- Assume that the activities in Problem 3.11 have the following costs to shorten: A, $300/week; B, $100/week; C, $200/ week; E, $100/week; and F, $400/week. Assume also that you can crash an activity down to 0 weeks in duration and that every week you can shorten the project is worth $250 to you. What activities would you crash? What is the total crashing cost? Note: The attached photos is the activities in problem 3.11.Draw the following project schedule (See textbook section 8.8 and exhibits 8.11-8.15) Task A duration 12 days Task B duration 4 days, the predecessor is task A Task C duration 6 days, the predecessor is task A Task D duration 8 days, the predecessor is task C Task E duration 6 days, the predecessor is task B Task F duration 4 days, the predecessor is task C Task G duration 8 days, predecessors are tasks D, E, and F Indicate the ES, EF, LS, LF and slack time (format as displayed in examples) and provide a legend with the diagram. Highlight/Identify the critical path on the diagram. Show the enumeration method to determine the critical path. Be sure that both methods indicate the same critical path.A plumber has decided to use the techniques of project management in order to plan a job. He knew all the different activities of the job, their precedence and their average durations. They are shown on the table below.ActivityDuration (days)Preceding activitiesA3NoneB3NoneC4AD9AE4B and CRequired:1. Draw a network diagram representing the sequence of activities and the dependence between them.2. Determine how long it will take to complete the job by conducting the forward pass3. By conducting the backward pass, identify the critical path and the non-critical path(s).Note:The work for this task should be produced using Word drawing facilities. The forward and backward passes should be clearly shown on the diagram. The calculations should be shown next to the network diagram.
