Enterprise modelling - base for information system planning.

Today the modelling of an enterpise is enabled by various methods which are used for different purposes and views upon the enterprise. Using an object-oriented approach the Integrated Enterprise Modelling (IEM) concept will integrate different moddelling views in one consistent manufacturing enterprise model and will provide a modelling base for construction of an enterprise model from a user's point of view. Therefore the basic constructs like object class structure and a related process decription method via generic activity model will be presented. The kernel and the main views of a manufacturing enterprise model will be derived. The outline of a supporting computer aided tool will be presented.
