Formal languages for construction process modelling

Abstract:"Numerous modelling methods and languages have been developed for describing different aspects of industrial and other processes. Each method, for instance the widely used scheduling method as used in project planning software, has a specific scope (i.e. the modelling of the sequence in time of interdependent activities) for which it has been designed and for which it is well suited. Used outside this scope the method may prove quite inadequate. A number of such methods have either been used or proposed for the modelling of construction processes. In order to create the basis for a next generation of more general purpose process modelling tools an analysis has been made of six such methods. In order to illustrate the concepts and graphical notation of each method a simple example of making the foundation of a summerhouse with a sauna is used. Additionally the concepts of each method have been modelled using a uniform methodology, the EXPRESS information modelling language. Based on the analysis a synthesis method, called IDEF++ is proposed and defined in EXPRESS. The method is defined on the semantic level, as its main purpose would be to enable the storing of process descriptions in a database format, enabling multiple user views to the same information. A prototype application is developed to demonstrate different views."
