The following is NOT one of the advantages of CPM and PERT:a) Straightforward concept and not mathematically complex.b) Graphical networks help highlight relationships among project activities.c) Critical path & slack time analyses pinpoint activities that need tobe closely watched.d) Project documentation and graphs point out who is responsible for variousactivities.e) Precedence relationships must be specified and networked together.f) Applicable to a wide variety of projects.
3.1 Draw an Activity-On-Arrow (AOA) network diagram representing the project. Put the nodenumbers in circles and draw arrows from node to node, labelling each arrow with theactivity letter and estimated duration. 3.2 Identify all the paths on the network diagram and note how long they are. 3.3 What is the critical path for this project and how long is it? 3.4 What is the shortest possible time needed to complete the project?
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.
A potential conflict on projects is work scope; conflict can arise from differences of opinion on all the following except A. how much work should be done. B. how the work should be done. C. at what level of quality the work should be done. D. the cost of the work to be done.
Which of the following statement about critical path is true? O a It describes the shortest of all paths through a network O b. Some activities on the critical path may have slack O c Every network has exactly one critical path Od. It is the longest path of the interrelated activities in a project with zero slack time
A project manager has compiled a list of major activities that will be required to install a computer information system in her firm. The list includes estimated completion times for activitiesand precedence relationships.ActivityImmediatePredecessorEstimatedTimes (weeks)A — 2-4-6D A 6-8-10E D 7-9-12H E 2-3-5F A 3-4-8G F 5-7-9ActivityImmediatePredecessorEstimatedTimes (weeks)B — 2-2-3I B 2-3-6J I 3-4-5K J 4-5-8C — 5-8-12M C 1-1-1N M 6-7-11O N 8-9-13End H, G, K, Oa. Construct a network diagram. You can use either AOA or AON (see Example 5).b. If the project is finished within 26 weeks of its start, the project manager will receive a bonusof $1,000; and if the project is finished within 27 weeks of its start, the bonus will be $500.Find the probability of each bonus.
Draw a A-O-A network diagram for the project having 9 activities with the following inter-relationship. C follows D but precedes F; C follows B but precedes H; G follows F but precedes I; E follows A but precedes I; D follows A; H and I terminate at the same time; A and B start at the same time
You may need to use the appropriate technology to answer this question. Mueller & Associates is a urban planning firm that is designing a new public park in an Omaha suburb. Coordination of the architect and subcontractors will require a major effort to meet the 43-week completion date requested by the owner. The Mueller project manager prepared the following project network. A project network with 10 activities and 14 directed arcs is shown. Activity Start is connected to activity A. Activity A is connected to activity B, to activity C, and to activity D. Activity B is connected to activity F. Activity C is connected to activity E and to activity F. Activity D is connected to activity E. Activity E is connected to activity G and to activity Finish. Activity F is connected to activity G and to activity H. Activity G is connected to activity H. Activity H is connected to activity Finish. Activity Finish has no arcs directed to other activities. Estimates of the optimistic, most…

27. Consider a project with six activities: G, B, C, D, E, and F. Assume G and F can be started as soon as the project is kicked off. B can start as soon as G is completed, C can start as soon as both G and F are completed. D will start as soon as both B and C are completed. E will start as soon as D finishes. Which of the following choices is the correct collection of immediate precedence relationships in the project network? G--> B, F--> C, B --> D, C--> E, D--> E, F--> D G--> B, G--> C, B --> D, C--> D, D--> E, F--> C G--> B, G--> C, B --> D, C--> D, D--> E, D--> F None of choices G--> B, F--> C, B --> D, C--> D, D--> E, F--> D G--> B, G--> C, B --> D, C--> D, D--> E, D--> F
