URP 4253: Project Planning & Evaluation Techniques
Application of CPM and PERT PERT and CPM, acronyms for "program evaluation and review technique" and "critical path method", respectively, are network techniques used to aid in the planning, scheduling, monitoring, and control of activities which are related to each other. Comparative discussions of CPM and PERT CPM CPM is frequently used in the construction industry to help organize and schedule those activities which together constitute a given construction project.
PERT PERT was first used to help coordinate the activities in the development of the Polaris missle system.
In using CPM, one assumes the activity times PERT allows for uncertainty and statistical are known with certainty (deterministic variation in activity times (stochastic activity times). activity times); Benefits of PERT Benefits of CPM ■ Expected project completion time. ■ Provide a graphical view of the ■ Probability of completion before a project specified date. ■ Predicts the time required to complete ■ The critical path activities that the project directly impact the completion time. ■ Shows which activities are circuital to ■ The activities that have slack time and maintaining the schedule and which that can lend resources to critical path are not activities. ■ Activity starts and end dates.
