Petri nets for simulation and modeling of construction systems

Simulation and modeling of construction systems have been actively researched over the past 20 years. This paper demonstrates how Petri nets, a powerful modeling tool previously used for modeling computer networks and automated manufacturing systems, can be used effectively for modeling construction systems. This paper describes the Petri net approach to modeling and shows how models of construction systems can be developed. Several common Petri net structures and features useful in construction system modeling are described. Time and color Petri nets and their application in modeling specific characteristics of construction systems are discussed. Two illustrative examples are presented and the advantages and disadvantages of Petri nets as tools for the modeling and simulation of construction operations are detailed.
