Examples of subcontractor

• When subcontractors cannot provide enough resources, they hinder their own per formance, that of other subcontractors, and ultimately the entire project.

• Disputes among subcontractors would follow if the causes of delays are not clearly established and the cost overruns are not reimbursed properly.

• Another notable feature is that every subcontractor only considers its own activities, but it will also enhance global outcomes.

• Other, more complex middle agents, such as subcontractors, are not available in this architecture.

• Therefore, the subcontractors may try to change the project schedule in order to accommodate their wishes.

• The problem we are trying to solve is rescheduling activities through distributed coordination when subcontractors have available resources that differ from the needed resources.

• Thus, projects need a new distributed coordination approach wherein all of the concerned subcontractors can respond to changes and reschedule a project dynamically.

• Traditional centralized coordination techniques used by general contractors become insufficient as subcontractors per form most work and provide their own resources.
