As long as the players move in independent parts of the net, they do not know of each other; when they synchronize at a joint transition, each player gets informed of the causal history of the other player. We show that for Petri games with a single environment player and an arbitrary bounded number of system players, deciding the existence of a safety strategy for the system players is EXPTIMEcomplete.} }

abstract = {Dynamically typed objectoriented languages enable programmers to write elegant, reusable and extensible programs. However, with the current methodology for program verification, the absence of static type information creates significant overhead. Our proposal is twofold: First, we propose a layer of abstraction hiding the complexity of dynamic typing when provided with sufficient type information. Since this essentially creates the illusion of verifying a staticallytyped program, the effort required is equivalent to the staticallytyped case. Second, we show how the required type information can be efficiently derived for all typesafe programs by integrating a type inference algorithm into Hoare logic, yielding a semiautomatic procedure allowing the user to focus on those typing problems really requiring his attention. While applying type inference to dynamically typed programs is a wellestablished method by now, our approach complements conventional soft typing systems by offering formal proof as a third option besides modifying the program (static typing) and accepting the presence of runtime type errors (dynamic typing).},

We use standard theory for controller synthesis to derive the dynamic behavior of a lanechange controller.

We also consider the possibility of exchanging knowledge between neighboring cars in order to come up with the right decisions.},

abstract = { We present an approach to prove safety (collision freedom) of multilane motorway trac with lanechange manoeuvres. This is ultimately a hybrid veri cation problem due to the continuous dynamics of the cars. We abstract from the dynamics by introducing a new spatial interval logic based on the view of each car. To guarantee safety, we present two variants of a lanechange controller, one with perfect knowledge of the safety envelopes of neighbouring cars and one which takes only the size of the neighbouring cars into account. Based on these controllers we provide a local safety proof for unboundedly many cars by showing that at any moment the reserved space of each car is disjoint from the reserved space of any other car. } }

abstract = {We describe how CSPOZ, a formal method combining the process algebra CSP with the specification language ObjectZ, can be integrated into an objectoriented software engineering process employing the UML as a modelling and Java as an implementation language. The benefit of this integration lies in the rigour of the formal method, which improves the precision of the constructed models and opens up the possibility of (1) verifying properties of models in the early design phases, and (2) checking adherence of implementations to models. The envisaged application area of our approach is the design of distributed {\em reactive systems}. To this end, we propose a specific UML {\em profile} for reactive systems. The profile contains facilities for modelling components, their interfaces and interconnections via synchronous/broadcast communication, and the overall architecture of a system. The integration with the formal method proceeds by generating a significant part of the CSPOZ specification from the initially developed UML model. The formal specification is on the one hand the starting point for {\em verifying} properties of the model, for instance by using the FDR model checker. On the other hand, it is the basis for generating {\em contracts} for the final implementation. Contracts are written in the Java Modeling Language (JML) complemented by \CSPjassda{},
an assertion language for specifying orderings between method invocations. A set of tools for runtime checking can be used to supervise the adherence of the final Java implementation to the generated contracts.},

We discuss how properties of highlevel specifications of realtime systems combining the dimensions of process behaviour, data, and time can be automatically verified, exploiting recent advances in semantics, constraintbased model checking, and decision procedures for complex data. As specification language we consider CSOZDC, which integrates concepts from Communicating Sequential Processes (CSP), ObjectZ (OZ), and Duration Calculus (DC). Our approach to automatic verification of CSPOZDC rests on a compositional semantics of this languages in terms of PhaseEventAutomata. These can be translated into Transition Constraint Systems which serve as an input language of an abstract refinement model checker called ARMC which can handle constraints covering both realtime and infinite data. This is demonstrated by a case study concerning emergency messages in the European Train Control System (ETCS). For CSPOZDC we also discuss a UML profile and tool support. } }

In this paper, we propose using CSPOZ, a specification language combining Communicating Sequential Processes (CSP) and ObjectZ (OZ), to specify security automata, formalize their combination with target systems, and analyze the security of the resulting system specifications. We provide theoretical results relating CSPOZ specifications and security automata and show how refinement can be used to reason about specifications of security automata and their combination with target systems. Through a case study, we provide evidence for the practical usefulness of this approach. This includes the ability to specify concisely complex operations and complex control, support for structured specifications, refinement, and transformational design, as well as automated, toolsupported analysis. } }

abstract = { CSPOZ [Fis97,Fis00] is a combination of Communicating Sequential Processes (CSP) and ObjectZ (OZ). It enables the specification of systems having both a statebased and a behaviouroriented view using the objectoriented concepts of classes, instantiation and inheritance. CSPOZ has a process semantics in the failures divergence model of CSP. In this paper we explain CSPOZ and investigate the notion of inheritance. Behavioural subtyping relations between classes introduced in [Weh02] guarantee the inheritance of safety and ``liveness'' properties. \begin{thebibliography} \bibitem{Fis97} C.~Fischer. \newblock {CSPOZ}: A combination of {ObjectZ} and {CSP}. \newblock In H.~Bowman and J.~Derrick, editors, {\em Formal Methods for Open ObjectBased Distributed Systems (FMOODS'97)},

This combination is illustrated by specifying the train controller of a case study on radio controlled railway crossings. The technical contribution of the paper is a smooth integration of the underlying semantic models and its use for verifying timing properties of CSPOZDC specifications. This is done by combining the modelcheckers FDR [Ros94] for CSP and UPPAAL [BLL97] for timed automata with a new tool \emph{f2u} that transforms FDR transition systems and certain patterns of Duration Calculus formulae into timed automata. This approach is illustrated by the example of a vending machine. \begin{thebibliography} \bibitem{BLL97} J.~Bengtsson, K.G.

We begin by introducing and investigating finite traces as a simple abstraction of the transition behaviour of automata. Using finite traces safety properties of processes can be modelled. Later infinite traces or {\it streams} together with stream processing functions are studied. Using infinite traces more advanced phenomena like fairness and liveness properties can be modelled. We discuss and relate operational, denotational, algebraic and logical approaches to traceoriented models and explain methods for the specification and verification of process behaviour based on these models. } }

abstract = { UMLRT is an extension of UML for modelling embedded reactive and realtime software systems. Its particular focus lies on system descriptions on the architectural level, defining the overall system structure. In this paper we propose to use UMLRT structure diagrams together with the formal method CSPOZ combining CSP and ObjectZ. While CSPOZ is used for specifying the system components themselves (by CSPOZ classes), UMLRT diagrams provide the architecture description. Thus the usual architecture specification in terms of the CSP operators parallel composition, renaming and hiding is replaced by a graphical description. To preserve the formal semantics of CSPOZ specifications, we develop a translation from UMLRT structure diagrams to CSP. Besides achieving a more easily accessible, graphical architecture modelling for CSPOZ, we thus also give a semantics to UMLRT structure diagrams. },
