....may seem rather esoteric, it yields a unique solution of equation (1.2) for any positive integer values of p, q. Therefore G 3 implies in fact an infinite set of di#erent orderings and di#erent initial sets. The concept of a system has been dealt with in many basic monographs (see e.g. 8] [4], 6] 5] and many more) All these concepts, be it an input output model, an input state output model, the behavioral model, would consider the A(G i ) cases described above as mutually di#erent systems, although they are described by a single equation. Equation (1.2) is a very simple example. ....

....a symbolic representation of network behavior in form of a finite state automaton. 8 3. MODELING NETWORK BEHAVIOR WITH Q 2 A communication network is a dynamic system . Methods for modeling dynamic systems have been studied primarily in systems science and general systems theory (cf. [13], 14] However, these methods lead to quantitative dynamic models, which, as we stated earlier in this paper, are not easy for human network managers to deal with. Our main objective is to take this infinite state dynam ic system and abstract a simpler finite state qualitative dynam ic system ....

....This process of decomposition can be applied recursively until we end up with a collection of basic subproblems that can be treated (in some sense) independently. These ideas have been implemented for many problems with varying degrees of success (see, e.g. Albus, 1991; Knoblock, 1990; Mesarovich et al., 1989; Botvinnik, 1984) Implementations based on the formal theories of linear and nonlinear planning meet hard efficiency problems (McAllester and Rosenblitt, 1991; Chapman, 1987; Nilsson, 1980; Stefik, 1981; Sacerdoti, 1975) An efficient planner requires an intensive use of heuristic knowledge. ....

....structural, is perhaps best exemplified by Webster s definition of a group of units so combined as to form a whole and to operate in unison [32] This has been taken up in the systems literature in many forms. In mathematical systems theory this view is best expressed by the Mesarovic school [18] which sees systems as mathematical relations (subsets of the cross product of the constituents state spaces) We call this view structural because it focuses on the specific given types of relations among specific types of entities. It entails an entering into relation of multiple entities, ....

....langage est illustr ee par la force expressive qui est test ee sur la meme th eorie des categories. 1 INTRODUCTION The input output paradigm of systems theory is well known and has received much attention in the literature. Our work is inspired by the abstract presentation of systems theory in [MT89]. General Systems Logical Theory is based on the input output paradigm and was first proposed in [RJ86] it has since been applied to deriving the basic rules of tensor analysis in non Euclidean spaces in [MPR93] An important development has been to demonstrate that the categorical tool of ....

This includes the literatures on multi level systems (e.g. Dirickx and Jennergren (1979) Burton and Obel (1984) Van de Panne (1991) and Sethi and Zhang (1994) aggregation disaggregation methods (see Rogers et al. 1991) for a survey) and abstract systems theory (Mesarovic and Takahara (1989)) Some of the research described in later sections of this survey is also based on decompositions of decision problems. 5 Communication constraints The decomposition of decision problems shows the possibility of decentralization, but does not in itself quantify the benefits of doing so. For this, ....

....representation. II. Related Research Modeling and simulation of dynamic systems has always been an important issue in both science and engineering. General methodologies of modeling and simulation of dynamic systems have been studied extensively in systems science and general systems theory (cf. [4], 5] control (cf. 6] economics ( 7] 8] 9] and artificial intelligence (cf. 10] Differences between methods used in all of these disciplines are, to a great extent, due to different treatments of the issues of granularity and consistency of reasoning. The systems science approach is ....
....by critical curves and surfaces [32] In all of these approaches, the 4 notion of a critical hypersurface was not fully formalized. It was introduced using examples from particular domains. In this paper we define this notion for a more general class of systems: general dynamic systems (GDS) [4]. None of the previous approaches made a clear connection to the theory of dynamic systems. In the systems science control literature the notion of the hypersurfaces has been addressed (cf. 19] 20] 21] 22] 23] 24] 25] However, as we mentioned earlier, it was limited to the system ....

....interpretation of the GDS model. The interpretation maps the continuous GDS model to a discrete finite state automaton. The qualitative abstraction functions and the automaton are combined to form a Qualitative Dynamic System (QDS) model of the qualitative plant. A general dynamic system [Mesarovic, 1989 #4] S, is an 8 tuple S = T, X, W, Q, P, f, g, 1) where: T the time set with an order relation on it, X the input set, W the output set, Q the inner state set, P the input processes, functions p: T X, f: T Q p Q, the state transition function, g: Q W, the output ....
