An alternative approach for modeling of interference in discrete-event systems

Simulation modeling represents a framework within which discrete-event syst ems such as construction processes can be analysed, designed and improved. Modeling of some characteristics inherent in general construction processes , however, is difficult; One such characteristic is interference. This pape r proposes a construction process-based methodology developed from a Petri Net approach for the modeling of the behavior. This new methodology provide s an intuitive approach by the addition of three new modeling elements to b asic Petri Net constructs. The functionality of the new elements is describ ed and the implementation of the proposed methodology is provided. The appr oach provides a means of reflecting reality and practicality in constructio n-process modeling. It properly addresses the consequences of interference in terms of what happens to the interfered activities and to the involved r esources.
