....main distinction with the above mentioned techniques. Timed automata have been de ned and investigated in many papers [ACD93,AD94,TY01] We adopt the de nition given in [ACD93] 3 Timed Automata In this section we brie y recall the concept of timed automata, which was introduced by Alur and Dill [AD90] Timed automata are extensions of nite state automata with constraints on timing behaviour. The underlying nite state automata are augmented with a set of real time variables, called clocks. We start with introducing some auxiliary notation. Hereafter, IN = f0; 1; 2; g denotes a set of the ....

.... CC77, CC92] in order to obtain an abstract version of the system which is nite and computationally treatable; another approach, that is mostly applied to timed automata, calculates a quotient of the in nite set of states obtaining an equivalent automata with a nite number of states (see [AD90] for details) The in nite state approaches can also be classi ed into two categories. Firstly, we have those approaches that work symbolically by exploring the in nite statespace. Some of these approaches de ne abstractions to construct a nite model of the system which can be automatically ....

....complex structures, but also for exploiting the existence of symmetry in scalar types. 2.2. 3 Automata Theoretic Aproaches The foundations for automata theoretic approaches [53, 89, 90] is that a temporal logics formula j can be viewed as an acceptor of infinite words over the alphabet S = 2 [2]. Thus, the language L j which contains the words accepted by j, is a w automaton construct of the model M , i.e. A M ,if and only if: L (A M L A j where A j is the w automaton constructed from the TL formula. This approach is useful for extending model checking into a infinite state ....

....interpretation, approximation of real time safety properties can be formulated in the have been formulated in this framework [WT94, DT98] An approach to approximate also liveness is presented in Chapter 7. Timed Automata Model. For model checking, the timed automata model of Alur and Dill [AD94] is most influential for this thesis. The language is basically an extension of finite state machines with additional real valued variables that represent clocks. Transitions can be guarded by Boolean expressions over these clocks and clocks can be reset when taking a transition. Properties of ....
....over time. See [BRJ99, Kob01b,Kob01a] for an more detailed exposition. The first object oriented modeling languages appeared between the mid 1970s and the late 1980, as methodologists started to experiment with new modeling concepts that were tailored for the new object oriented design paradigm. In 1994 there were around 50 di#erent object oriented modeling languages around [BRJ99] The standardization of modeling languages started out, as Grady Booch and James Rumbaugh collaborated within the company Rational and sought to join their development methods, Booch and OMT with the Unified Method ....
