The control of construction activities usually involves monitoring and manipulating multiple attributes at the same time. In this paper, a multi-attribute real-time control system for construction activities is presented. The proposed system monitors and controls two or more attributes, utilizing a set of single-attribute control systems operating in parallel. The proposed system includes a conflict resolution unit which is responsible for resolving any conflicting commands resulting from the individual parallel control systems. A feed-forward control loop is also integrated in the proposed model. The feed-forward loop assesses the controllability of the system, and either permit operation, stop operation or suggests adjusting the control standards.
