Enhanced CPM/LOB Repetitive Scheduling Formulation to Meet Deadlines
Large portion of construction projects involve large number of units (e.g., highway sections, floors, housing units, etc.). For these repetitive projects, existing scheduling formulation integrates CPM network analysis with the line-of-balance (LOB) analysis. Despite the CPM/LOB benefits in determining the necessary crews that meet a given deadline, however, CPM/LOB formulation has a serious drawback as it underestimates the number of crews and can result in a project delay although the deadline is relaxed. To overcome this drawback, this paper proposes an improvement method that modifies the project deadline to avoid creating schedules that lead to project delays, while keeping resource usage at an optimal value. The paper introduces two variations of the CPM/LOB formulation for shifted and parallel crew arrangements and uses an example to highlight the deadline satisfaction problem. The paper then introduces the detailed formulation of the proposed solution and demonstrates its effectiveness. The paper contributes to improving the schedule computation for repetitive projects to systematically meet deadlines and project constraints.
