....presents basic definitions used in the paper. For brevity, the reader is assumed to be familiar with Petri nets, a formalism used to specify concurrent systems. The reader is referred to [26] for a general tutorial on Petri nets. A. Transition Systems A transition system (TS) is a quadruple [27] A = S; E; T ; s in ) where S is a non empty set of states , E is an alphabet of events , T ae S Theta E Theta S is a transition relation, and s in is an initial state. The elements of T are called the transitions of the TS and are often denoted by s instead of (s; e; s ) The ....

....and vice versa. Index Terms Graph visualization, transition systems, state spaces, cone trees. I INTRODUCTION HE last decade has seen substantial progress in the analysis of computer based systems. A central approach in this analysis is to describe the behavior by means of a transition system [1] consisting of states and possible transitions between these states. The most commonly used techniques based on explicit state enumeration can now deal with transition systems of billions of states. So called symbolic techniques deal with even larger systems, employing a form of abstracted state ....

....subgraph of G that is rooted on a vertex e is written G[e] Synchronized Product of Rooted Graphs. The synchronized product of graphs has been introduced by Arnold and Nivat [2, 21] It is an essential part of the semantic of interacting processes. For more material, the reader may refer to [1]. We introduce here a definition that is a variant of Arnold and Nivat s one. Indeed, in the scope of this paper, we need a product that takes as entry some rooted graphs and returns a rooted graph as well. Given n alphabets C 1 ; Cn possibly extended with , a synchronization constraint C ....

....at least time units after becoming enabled, and the upper bound restriction states that time units after becoming enabled. The following definitions present the concepts of transition system and TTS, together with the semantics of these models, i.e. the concept of run . Definition 4. 1: [3] A transition system (TS) is a quadruple (h( where is a non empty set of states, is a non empty alphabet of events, D[ is a transition relation, and is the initial state. Transitions are denoted . An event is enabled at state if lI . We will denote the ....

....satisfied. Excitation closure: For each event . Event effectiveness: For each event Bisimulation between two TS s corresponds to the equivalence of state transition graphs, which is traditionally used in automata minimization, and is formally defined as follows. Definition 3. 1 (Bisimulation [1]) Let and be two TS s with the same set of events. A bisimulation between and is a binary relation between and such that ia) for every , there exists such that ; ib) for every , there exists such that ; iia) for every and for every such that , there exists such that ; iib) for every and for ....

....is essentially one which kills the 2 cells , that is the morphisms between machines, so that the bicategory of minimized machines is locally discrete. We begin in Section 2 with a study of a minimization for labelled graphs by generalizing the notion of bisimulation for transition systems [Arn92]. To make the minimization functorial we consider path lifting morphisms of labelled graphs and then consider points and reachability. The resulting minimization process is an idempotent monad. In Section 3 we make the minimization compositional by defining a bicategory of spans of graphs on ....
....minimization functor on a suitable category of labelled graphs viewed as a slight generalization of labelled transition systems. We find that minimization is adjoint to the inclusion of the minimized labelled graphs. Transition systems are often used in modelling parallel processes. Definition 1 [Arn92] Let A be an alphabet, i.e. a finite set. A transition system labelled by A is = S, T, #, #, #) where S and T are sets of states and transitions, # : T and # : T S define the source and target of transitions, and the labelling # : T 4 makes the mapping ##, #, ## : T S injective. ....

....between the individual behaviours. Then the product of the Labelled Transition Systems with respect to the Synchronization System is built; it figures out the behaviour of the whole of the interacting system. Boolean properties can then be computed on the states and transitions of this graph[2]. The availability of a powerful model checker, the MEC tool[3] settled it. Temporal study The formal approach to temporal aspects of the system, more precisely the respect of every deadline, has been since the beginning considered out of reach of the automata approach, as time could be in no way ....
