Abstract. The business model of a modern enterprise is a basic element for the most adequate and sound reaction to a change of the enterprise’s social-economic environment. In order to achieve desired results of the enterprise work, this reaction should take enterprise features into consideration. By means of metamodeling and system theory, it is possible to create an integrated business model system. This system is based on the enterprise features and the business models are implemented using a common set of entities. Figs: 4. Tabl.: 2. Refs: 25.
