Current practice separates subcontractor management from schedule control. A factor-based model is proposed to measure the sensitivity of each factor to uncertainty by decomposing the effects of uncertainty at the level of activity, and then integrating these individual effects at the path level. By viewing the path of a schedule network as the working route of one or several subcontractors, the proposed model enhances knowledge of what to control on each subcontractor, such as those factors that a subcontractor is sensitive to, and the subcontractors that are most sensitive to a particular factor. Consequently, a project delay is averted. And management can control subcontractors and the schedule in an integrated manner.
