Abstract : This report develops the major theoretical concepts for the integration of three diverse engineering modeling languages: IDEFO, IDEFIx, and XSpec. IDEFO is a high level modeling tool based on functional decompositions, IDEFIx is a detailed data modeling tool and XSpec is a simulation tool based on object-oriented decompositions. The approach used to integrate the tools is to develop a meta-model of the three modeling languages. These meta-models are examined, and a single combined meta-model is developed. All three systems use the same combined meta-model. This ensures that any changes to the system made in one language is reflected in the other languages automatically. The report is divided into the following sections. A short description of each of the languages is given. These are not intended to be exhaustive, they are provided so that the reader is familiar with the terminology used in each of the methods and to get a feel of the types of models each language produces. The meta-models of IDEFO and XSpec are given. The approach used to develop the combined meta-model is given. Finally, a complete description of the meta-model is presented.. ..IDEF, IDEFO, IDEFIx, XSpec, Activity Based Modeling, Engineering Modeling Language, Object oriented, Meta-Model.
