This article gives an overview of the most characteristic steps of the relational modeling strategy, from the component to augmented abstract block diagrams, putting the emphasis on some epistemological aspects. Robert Rosen's modeling strategy is a formal representation of biological organization, specifically of circular causality. In this regard, the most important contribution of Robert Rosen is the anschaulichkeit - the intuitability - of the closure of the organization and of the intertwinement of the different Aristotelian causes, even if they are incommensurable.

The transition model is represented in the form of discrete state space. The target values for each particular rank are deter mined by the user defined trajectory function. Optimal recruitment and transition dynamics is determined by the minimization of the differences between desired and actual state values. Analytical approach to the optimization is considered in order to provide proper control strategy.

Each of these points are made more precise by considering what changes they require to be made to the basic equation characterising anticipatory systems. In addition, some philosophical questions concerning the content of anticipatory representations are considered.

Simulation-based decision support is a holistic methodology for decision assessment in organizations. System dynamics is a proper methodology for modeling and testing the dynamic hypotheses of organizational systems. The role of subjects in model development and its validation from cybernetic, psychological and cognitive perspectives are discussed in this paper. Group participation in model building and validation is suggested in order to prevent the manipulation of dominant subjects and/or implicit dictators during modeling. This paper concludes with some useful examples of systems simulation in solving real problems.

An anticipatory model of CT consists of the following parameters : flexibility, originality, fluency and elaboration. The intellectual abilities Int[tH] consist from two components : Creative abilities C[tH], and Learning contribution L[tH]. The mathematical model of the intellectual abilities Int[tH] = C[tH] + L[tH] = {C0MAX – [tH – T0H]²} + kL * tH Here C0MAX is maximum creative abilities, tH is age, kL is learning coefficient.

At first it lists the different steps of the life cycle of the Automated Production Equipment, then expounds the need for several types of models, corresponding to different aspects of the control development, and shows the problems brought up by their obtention or their validation. It reviews some control methods, with special emphasis on their anticipatory aspects. It tries to make clear not only the main ideas, but also the operating conditions corresponding to each method.
