Abstract

 

This paper compares two computer-based modelling and simulation methodologies applicable to construction, the CYCLONE system and Petri Net, to a conventional manual simulation methodology, the multiple activity chart. The main objectives of the comparison are to assure the quality of the results obtained from the two computer-based methods and to show how Petri Net, a general modelling tool, can be used to model construction operations. Petri Net is also compared to CYCLONE, a construction modelling system, to show its potential as an alternative modelling tool for construction. Comparisons of the graphical models and modelling elements of the two computer-based systems are also made. Advantages and disadvantages of the two systems in the construction context are discussed. Results from the simulation runs show that CYCLONE and Petri Net are accurate systems to construction modelling and simulation. Petri Net also shows its potential to be a powerful construction-modelling tool.
