Abstract
This research applies Project Evaluation and Review Technique (PERT) model to estimate acceptable duration for execution of each activity having random variable of time and some probability distribution for sand dredging operation in Niger Delta. The study takes into account proper planning, scheduling, controlling and allotment of dredging activities time using a project network model PERT. The model evaluated how acceptable time and saving cost could be achieved in a scenario of activities having random time variables. Readily available data of activities time from 2014 – 2017 were used to analyze the time estimate for various activities at a selected dredge site Aleto-Eleme in Port Harcourt metropolis Rivers State-Nigeria. The PERT was applied for the data analysis, to construct the PERT scheme for the dredging operations. Finally, parametric control for project evaluation and review techniques of acceptable time for the dredging activities were determined.
