Introducing a new concept and approach to modeling construction

Modeling construction is a critical step for understanding it and improving its performance. The thrust of this research paper is the need for the development of valid credible models as a logical precursor to automation. This article reviews the key models used to represent construction. Through this examination, it makes an important distinction between process and system modeling concepts. This distinction is the basis for concluding that no single tool, by itself, is accurately capable of fully modeling both construction system and construction work processes. Thus an integrated approach to modeling is required. Accordingly, the research conducted by the writers utilized a new integrated modeling approach that combines a set of descriptive tools to allow the development of various perspectives of construction. This article presents one of these tools as a new system modeling concept that overcomes deficiencies in current system modeling approaches. The power of this new model is illustrated in a detailed comparison among key current system modeling concepts.
