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.
