Graphical-based method for transient evaluation of construction operations

Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns. The complexity of resource interactions combined with external factors creates a transient environment for construction operations. This research uses computer simulation techniques and a graphical method, DISCO (Dynamic Interface for Simulation of Construction Operations), for the evaluation of the transient effects of construction operations. DISCO uses the CYCLONE schematic model diagram of a process as the modeling framework and allows breaks or interruptions in the simulation run and stopping of the simulation time clock to investigate the transient states of resources and tasks in a process. The scope of the study focuses mainly on the transient effects caused by the process mobilization of construction operations every day. Two construction operations are used as case studies for the investigation. Results of the study and observations are discussed.
