Generic Enterprise-Modelling Language

Generic enterprise modelling languages (GEML) define generic constructs (building blocks) for enterprise modelling. Generic constructs which represent the different elements of the operation improve both modelling efficiency and model understanding. These constructs have to be adapted to the different needs of people creating and using enterprise models. Therefore different languages may exist which accommodate different users (e.g. business users, system designers, IT modelling specialists, others).

Modelling the enterprise operation means to describe its processes and the necessary information, resources and organisational aspects. Therefore modelling languages have to provide constructs capable of capturing the semantics of enterprise operations. This is especially important if enterprise models are to support the enterprise operation itself.

Model-based decision support and model-driven operation control and monitoring require modelling constructs which are supporting the end users and which represent the operational processes according to the users perception.

Modelling languages increase the efficiency of enterprise modelling. In addition they allow a common representation of the enterprise operation. Modelling languages have to support the modelling of all entity types across all phases of their respective life cycles. In addition, modelling languages have to provide generic constructs as well as macro constructs (GEMs) build from generic ones. The latter will further enhance modelling productivity.

Famous quotes containing the words generic and/or language:

    “Mother” has always been a generic term synonymous with love, devotion, and sacrifice. There’s always been something mystical and reverent about them. They’re the Walter Cronkites of the human race . . . infallible, virtuous, without flaws and conceived without original sin, with no room for ambivalence.
    Erma Bombeck (20th century)

    But as some silly young men returning from France affect a broken English, to be thought perfect in the French language; so his Lordship, I think, to seem a perfect understander of the unintelligible language of the Schoolmen, pretends an ignorance of his mother-tongue. He talks here of command and counsel as if he were no Englishman, nor knew any difference between their significations.
    Thomas Hobbes (1579–1688)
