A study is presented, which is directed at finding a solution to the problem of compressing networks having overlapping activities. The method involves the use of cost duration charts, network diagrams and linear programming. The computer is used to solve the linear programming model. The results give information pertaining to earliest start and finish times of activities, what activities to expedite in order to complete the project within the specified time limit and by how many days, how much money should be allocated to each activity and what additional costs are incurred in expediting the work.
