1 Chapter 8 Project Management (PM) 2 To understand the basic concepts of network models for project management To learn the solution procedures of CPM (Critical Path Method) Drawing a project network Finding the earliest time, the latest time and the activity slack time Finding the critical path To examine activity scheduling based on earliest time, latest time and total slack To examine project crashing with Linear Programming Chapter Outline 3 Large-scale projects consist of numerous specific activities or jobs that must be completed, some in parallel and others in sequence, by various individuals and groups. The management must plan , schedule and control the jobs so that the entire project is completed on time. A complicating factor in carrying out this task is the interdependence of the activities. For example, some activities depend on the completion of other activities before they can be started. Basic Concepts of Project Management (1 of 2) 4 Project managers look for methods that will help them answer questions such as: What is the earliest time that the entire project can be completed? Among the activities comprising the project, which are likely to be the “ bottleneck ”( critical ) activities that will directly affect the project duration? What should be the scheduled start and finish time of each activity? How long can “ noncritical ” activities be delayed before they cause a delay in the entire project? …( and more ) Basic Concepts of Project Management (2 of 2)

5 Gantt Charts A popular tool for planning and scheduling simple projects CPM (C ritical P ath M ethod) Developed by J.E. Kelly of Remington-Rand Corporation and M.R. Walker of Du Pont to assist in the building and maintenance of chemical plants at Du Pont Applicable when activity durations are known with certainty PERT (P rogram E valuation & R eview T echnique) Developed by Lockheed Aircraft, the U.S. Navy Special Projects Office for the Polaris Missile Project Applicable when activity durations are not known with certainty Linear Programming Applicable when there may be other additional constraints, e.g. resource limitations Techniques for Project Management 6 Phase 1 – Formulation 1.1 Decompose the project into simpler activities 1.2 Determine precedence relationships among activities 1.3 Determine the activity duration* * If the activity durations are known with certainty, then use CPM in Phase 2. Otherwise, use PERT Three Phases of CPM / PERT Application (1 of 3) 7 Phase 2 – Planning (by CPM / PERT) 2.1 Construct project network 2.2 Determine the earliest and the latest completion time 2.3 Identify critical activities and the slack for non- critical activities 2.4 Determine critical path Three Phases of CPM / PERT Application (2 of 3) 8 Phase 3 – Control 3.1 Monitor project progress 3.2 Make necessary adjustments Three Phases of CPM / PERT Application (3 of 3)
