This chapter describes the key concepts for modeling the organization?s enterprise architecture using the Unified Modeling Language (UML). Enterprise architecture consists on defining and understanding the different elements that shape the organization and how these elements are inter-related with the purpose of understand and facilitate organizational evolution and change. It separates core organizational concerns as different architectural views; the authors argue that modeling the multidimensional aspects of the enterprise should be organize...
Function is a key concept to integrate object modeling and process modeling in design. In this paper function is defined as a part of FBS (Function-Behavior-Structure) Diagram, where function is a description of behavior abstracted through recognition of behavior for utilization. Function defined above is then used in FEP (Functional Evolution Process) to represent design processes. In FEP, function can be evolved in three ways, i.e., decomposition evolution, causal evolution, and "patch" evolution. We show a FEP model of design of a weighing s...
Abstract Incremental modeling is the ability to incrementally add new and more specialized modeling capabilities to existing models, thus creating larger, more complex, and more specialized models. Some of the basic functions of the object-oriented integrated modeling support (IMS) system are described. Elemental modeling constructs are presented, and the creation of the models is discussed. Capabilities are based on the object-oriented principles of abstraction, encapsulation, class-subclass structure, inheritance, polymorphism, and specializ...
Abstract This paper presents a component oriented modeling environment for building hybrid dynamic models of physical system. The modeling environment is created using the generic modeling environment (GME), a meta programmable visual modeling application developed at the Institute for Software Integrated Systems (ISIS). The core of the modeling language itself is a hybrid extension of the bond graph modeling language. The advantages of an object-oriented approach to physical system modeling combined with the advanced features of GME for manag...
Abstract For many companies, the strategic as well as the organizational fit of their information systems is a pivotal factor for staying competitive. At the same time, there is an increasing demand for integrating business processes and informations systems with those of customers and suppliers. The resulting need for organizational changes and the introduction of corresponding information systems is a challenging task. The complexity of the task requires a separation of concerns. At the same time it causes language barriers between various s...
Abstract This paper describes a nonlinear transmission line modeling technique that can be employed to model power electronic circuits. The nonlinearities that can be dealt with also include the switching action of the power devices as well as the nonlinear behavior of saturable inductors and multilayer capacitors. With this new nonlinear technique, the transmission line modeling technique can now be used as a generalized discrete-time modeling tool for power electronic circuits. The nonlinear technique is demonstrated in two examples and the ...
Abstract The modeling of electrical characteristics of connections is an important stage of the design phase of a structure. Indeed, they have an impact on the current density distributions inside conductors as well as on the current distributions when several components are connected in parallel. This modeling has to be modified in case of a return plane in the studied structure as for power electronics or railway applications. For the first field the cooling system itself can be a ground plane and for the second one, the earth has to be mode...
Abstract Intelligent control of home appliances, have in recent years, attracted much theoretical attention, as well as becoming a major factor for industrial and economic success and rapid market penetration. Washing machines represent an important market. Intelligent control techniques are capable of providing useful means for both easier use and energy and water conservation. In this paper, we use two techniques that we have successfully used in other intelligent modeling and control applications. Firstly, we use a neuro-fuzzy locally linea...
Abstract In this paper we present a methodology which makes the task of modeling failure prone discrete event systems (DESs) considerably less cumbersome, less error prone, and more user-friendly. In order to model failures, we augment the signals set of the rules based formalism proposed by the co-authors of this paper, to include binary valued fault signals, the values representing either a non-faulty or a faulty state of a certain failure type. The rules based modeling formalism is further extended to model real-time systems, and we apply i...
Abstract This paper presents a correlation of results obtained by the authors in the modeling and simulation of left/right asymmetry (LRA) development in artificial embryology systems with its role in the analysis and modeling of developmental processes, such as in biology. LRA is presented as a different level of developmental stage in reference to the 2 basic types of asymmetry presented by all developing embryos (anterior-posterior and dorsal-ventral). Conclusions are presented on how our results support and help to understand the current r...
