Abstract: Construction managers are facing the increasing pressure from the owner to finish a project safely, on time, with the desirable quality and within the budget. These pressures make construction managers more and more focusing on construction operations planning and resource balancing. To provide an accurate and quick evaluation of a??what ifa?? scenarios, for decades, researchers in construction have used discrete-event simulation in modeling and analyzing construction operations. Construction Simulation technology contributes in modeling and evaluating the predefined alternatives for construction operation in a controlled environment of simulation systems. However, the complexity of comparing construction operation alternatives in simulation systems and the lack of a user-friendly interface have prevented this technology from being widely adopted in the construction industry.The goal of this research was to develop a simulation modeling method which enables construction managers to build up a construction simulation model visually and compare and evaluate different construction operation scenarios rapidly. This research proposed a Component-State based Criteria Simulation (CS2) method specifically designed for construction operations. This approach integrates component-state based concept, criteria based mechanism for internal control idea and two-level representation modeling. A detailed template for major modeling elements that includes key attribute of the component and a graphical user interface based on the template were also developed to facilitate building the simulation model visually.A detail case study based on a S$450M construction project in Singapore along with several demonstrating cases were modeled and analyzed using on CS2 method. For each case, the visual simulation diagram was built and simulation model was constructed and executed. The case study results indicated the effectiveness of the methodology in modeling and analyzing construction operations. Through managing the simulation model with the Criteria Object in the method, the CS2 method helped construction managers to compare and evaluate different construction operation alternatives visually without rebuilding the whole simulation modeling.
