A PROCESS-BASED APPROACH TO VALUE-ADDED CONSTRUCTION - THE CYCLONE DISCO SYSTEM/

Recently, the study of processes and of non value-adding tasks at the process level has enjoyed a renaissance in the manufacturing sector be cause of the emphasis on total quality management and the work of W. E dwards Deming and others. Interest by the construction industry in the study of processes at this level has been negligible. In order to ach ieve better quality in construction, the industry must become more pro cess oriented and involved in the study of resource interaction. The C YCLONE modeling system provides an environment for flow charting and s tudying the interaction of resources within a construction process. Th e DISCO program which is integrated with the CYCLONE modeling system p rovides a graphical modeling and simulation environment which facilita tes the analysis of construction operations using simulation technique s. The CYCLONE modeling format and the DISCO program interface constit ute a foundation upon which improved process design and efficiency can be established.
