When we build simulation models and construct dynamical models for physical systems, we often do not do so using a clear overall framework that organizes our geometry, dynamics and models. How do geometry and dynamics intertwine to eeect system change over multiple abstraction levels? We present a methodology, called object-oriented physical modeling (OOPM), which builds on the currently accept...

Since 1996, various attempts have been made to unify different object-oriented modeling languages. As a result of this endeavor, two languages have been developed: the Unified Modeling Language UML [3] and the Open Modeling Language OML [2]. Both UML and OML introduce a distinctive new feature: they allow users to extend or even to modify the base language in order to adapt the language to spec...

This paper addresses two issues: how formal object modeling techniques facilitate the XML application development and how XML technology helps formal/graphical software design process. In particular, the paper presents a XML/XSL approach to the development of a web environment for Z family languages (Z/Object-Z/TCOZ). The projection techniques and tools from object-oriented Z (in XML) to UML (i...

Object Modeling Technique is widely applied in the field of software engineering; and in this paper we applied this technique to model a mobile robot including its behaviors and interactions with environment. The paper first describes key background knowledge about object oriented analysis in software engineering, behavior based robotics and their similarities. Then, based on these similarities...

The paper presents the methodical principles of business process modeling using the Semantic Object Model (SOM). The entire modeling approach of the Semantic Object Model (SOM approach) comprises layers for the enterprise plan, for business processes, and for application systems. Business processes are interpreted as procedures to carry out the enterprise plan. Application systems are interpret...

This paper is a short presentation of the SOM (Semantic Object Model) approach. SOM was created to fulfill two main objectives. The first objective is the revision of the traditional data modeling techniques in order to integrate them within an object oriented framework, without sacrificing the main object-oriented principles, namely encapsulation, extendibility and reusability. The paper advoc...

When we build simulation models and construct dy-namical models for physical systems, we often do not do so using a clear overall framework that organizes our geometry, dynamics and models. How do geometry and dynamics intertwine to eeect system change over multiple abstraction levels? We present a methodology , called object-oriented physical modeling (OOPM), which builds on the currently acce...

Graphical variant modeling refers to a novel approach to object-oriented modeling whereby a class overrides behavior inherited from a parent class by specifying variations in the graphical description of that behavior. This approach differs from conventional approaches wherein object behavior is overridden by replacing the entire description. This paper outlines the potential benefits of graphi...

The notion of associations is motivated and presented. This kind of association is seen as first class a concept in notations at both modeling and programming level. Among others the association support evolution of systems by adding descriptions and instantiations of associations to executing systems. 1 Motivation We briefly motivate our introduction of the notion of association by the problem...
