Duration Control System for Construction Project Using PERT

Abstract

The Program Evaluation and Review Technique (PERT) has been widely used as a tool for project management. In PERT analysis, the activity time distribution is assumed to be a beta distribution, and the mean and variance of the activity time are estimated. These support the critical path and the probability of the whole project. With the information of mean and variance of critical path, which is assumed as normally distributed, the probability of completion of a project with specified dates can compute. To establish a PERT Cost, one first develops a framework for gathering cost data for each activity. Using the Optimum Time- Cost Estimate Concept of Resource Allocation Supplement method of Cost Estimation, one can find the minimum cost for specific completion dates. The system in this paper gives the expected duration, critical path, probability and time-cost estimates of the whole project using the application of Bridge Construction.
