DIMA – Decentralized Integrated Modelling Approach

Abstract

Let us enrich ourselves with our mutual differences. Paul Valery 9.1 General Basics of DIMA A SC is characterized by uncertain interactions of the elements and distributed goals. SCs can be described by various models (static and dynamic, stochastic and deterministic, analytical and simulation, etc.), which are interconnected. SCs are also characterized by a set of interrelated structures. Furthermore, the SC elements are active. Their activities are based on their own interests and goals. Active elements cause the necessity for balancing SC partner interests, a large number of uncontrolled factors, and formalizing difficulties. Besides, the SC execution is accomplished by permanent changes in the internal network properties and the environment. It requires SC adaptation to the current execution environment. So, reflections of SC configuration, planning and execution models are needed. The other issue of SC modelling is the interlinking of conceptual and mathematical models in order to achieve adequate, scaleable and representative models and providing application independence. Such a complex nature of SCs requires a combined application of different disciplines and modelling approaches (see Fig. 9.1).
