A new scheduling method, where probability values can be assigned to activity durations, is proposed in this thesis. Probabilistic Scheduling Method (PSM) accepts activity durations tagged with probability or confidence intervals. Tests were carried out using examples of 3,7, and 9 activities to evaluate PSM's practical capability. The comparisons of PSM to Critical Path Method (CPM), Performance Evaluation and Review Technique (PERT), and Monte Carlo application to PERT (MC PERT) conclude that PSM results in similar most probable duration estimation. Further tests were implemented to evaluate PSM's capability to project schedule revision on an ongoing project. A microsoft Excel application was used to organize tests data and calculations. PSM computations are more industry friendly. They allow for a range of duration associated with a range of probabilites. PSM provides flexibility and simplicity, and also dependency information that will benefit its user in decision making

One of a number of techniques to increase efficiency in the engineering industry which have appeared in the last few decades is Critical Path Scheduling. It is not much used in the petroleum industry, because its application is limited, but in many activities associated with drilling it can save time and money. Its use is illustrated by applying it to a typical rig move.There is a time-cost relationship on any job. An unplanned job will take a time and have a cost which can be reduced by Critical Path Scheduling to a point where cost is minimal, because further reductions in time will involve overtime, airfreight, and other abnormal charges. These factors can be analysed and better judgements can be made.The method used to apply Critical Path Scheduling is the Time Scale Arrow Diagram. It is a manual technique suitable for small to medium size jobs which has advantages in analysis and presentation over conventional methods employing computers. A rectangular, or parallel line diagram is used.A rig move is a complex operation whose costs can be a significant part of those for a whole drilling operation. It is usual to rely on experienced personnel to arrange for the rig preparation, loading, trucking, and rigging up at the new location to be done in the most efficient way. Jobs vary depending on the arrangements between the operator and the contractor, distances, local conditions, and other such factors. The Critical Path Schedule enables an analysis to be made beforehand which will assist in obtaining maxiumum efficiency in the operation.

This paper aims to present a methodology for use in construction planning named the Repetitive Scheduling Method (RSM). Students on a graduate level construction management program can learn how to create a RSM schedule to be applied to a real project. Typically, the Critical Path Method (CPM) is used to plan general construction projects. This paper presents a case study wherein a CPM diagram is transformed into a RSM schedule for use in the construction of a green condominium. RSM is the most suitable tool for planning repetitive projects like condominium buildings, apartment complexes, or real estate development projects. It utilizes an uninterrupted flow of resource concept in order to eliminate manpower-related resource wastage. As a result, construction productivity can be improved by using the right construction planning tool on the right project. Interested graduate students researching construction engineering can apply RSM on their repetitive projects in the future.
