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.
The table below represents a IS project set of activities, its expected completion time (weeks) and preceding activities. Activity Expected Time (weeks) Preceding activities A 5 None B 4 None C 10 A D 8 B E 14 B F 6 C, D G 7 D, E, F H 3 F, G Draw a network diagram for the IS project shown above. For each activity, calculate its earliest completion time (TE) and latest completion time (TL). Label TE and TL on the network diagram. Calculate the slack time for each activity.
The table below show a set of activities of an IS project,its expected completion time (ET) and preceding activities. Activity Preceding Activity Expected Time (ET) A - 7 B A 9 C A,B 5 D C 17 E C 12 F C 7 G D,E,F 10 H D,G 7 Draw a network diagram for the IS project shown above.,and calculate its earliest completion time (TE), latest completion time (TL) and slack time (ST). If the activity E took 16weeks instead of 12weeks to complete ,what impact will it have on the project duration?
A contractor needs to complete a project. The project involves 10 activities (labeled A, B, ..., J) with precedence relationship in network below. The estimate (in weeks) of the duration of each activityis in the table below. a. The mean and variance of the activity time for A~F are given in the table. Find the mean and variance of the activity time for the remaining arcs.b. Identify the critical path and then compute the mean and variance of the project completion time.c. What is the probability that the project is completed between 32 and 36 weeks?d. What completion time should the contractor claims to be 95% sure of completing the project by then?
A project has these activities, precedence relationships, and activity durations: Activity Immediate Predecessor Activity Activity Duration (Week) a * 3 b * 9 c * 7 d a 12 e a,b 10 f c 11 g d 10 h e,f 7 i g,h 14 j c 15 k f,j 9 a. Construct a CPM network for the project. b. Compute the EF, LF, and slack for each activity. Write the values on the CPM network. c. Compute the ES and LS for all activities. Display the ES, EF, LS, LF, and slack values in a table. d. What is the critical path and its duration?
A political campaign manager must coordinate several activities to be prepared for an upcoming election. The following table describes the relationships among the activities that need to be completed, as well as the estimated times. Activity Immediate Predecessors Time (Weeks) A - 4 B - 6 C A 3 D A 4 E B, C 8 F B 7 G D,E 2 H F 1 Develop a project network for this problem. Determine the ES, EF, LS, LF, and slack time for each activity. Also determine the total project completion time and the critical path(s).
Please, I need help because I have no idea how to do any of these. 11. Building a backyard swimming pool consists of nine major activities. The activities and their immediate predecessors are shown. Develop the project network. For question number 12, you need to refer to question number 11. Also the first picture is for #11 and second picture(image) is for #12 12. Assume that the activity time estimates (in days) for the swimming pool construction project in Problem 11 are as follows: a. What are the critical activities? b. What is the expected time to complete the project? c. Based only on the critical path, what is the estimated probability that the project can be completed in 25 or fewer days?
A project consists of the activities in the following list. Times are given in weeks. Activity Preceding Time A -- 8 B -- 4 C A, B 7 D A, B 3 E C, D 5 F C, D 6 G E, F 4 Draw the project network diagram. Calculate each activity's ES, EF, LS, LF, and Slack using the project activity nodes on the project network diagram. What is the project completion time? Identify the critical path
