Stochastic Look-ahead Scheduling Method for Linear Construction Projects

Abstract

Many construction projects involve repetitive operations that are exposed to various constraints and uncertainties. During construction field execution, schedulers must maintain and update look-ahead schedules, which coordinate work for the next several weeks based on the most recent productivity achieved. This study enhances the traditional linear scheduling method used for scheduling repetitive construction operations with stochastic simulation to incorporate uncertainty in activity performance during field operations. The proposed Stochastic Linear Scheduling Method (SLSM) was implemented and demonstrated in a pipeline construction project.
