. We define a valuebased modal calculus, built from firstorder formulas, modalities, and fixed point operators parameterized by data variables, which allows to express temporal properties involving data. We interpret this logic over Crl terms defined by linear process equations. The satisfaction of a temporal formula by a Crl term is translated to the satisfaction of a firstorder formula containing parameterized fixed point operators. We provide proof rules for these fixed point operators and show their applicability on various examples. 1 Introduction In recent years we have applied process algebra in numerous settings [4, 8, 12]. The first lesson we learned is that process algebra pur sang is not very handy, and we need an extension with data. This led to the language Crl (micro Common Representation Language) [13]. The next observation was that it is very convenient to eliminate the parallel operator from a process description and reduce it to a very restricted form, whi...

. In existing simulation proof techniques, a single step in a lowlevel system may be simulated by an extended execution fragment in a highlevel system. As a result, it is undecidable whether a given relation is a simulation, even if tautology checking is decidable for the underlying specification logic. This paper introduces various types of normed simulations. In a normed simulation, each step in a lowlevel system can be simulated by at most one step in the high level system, for any related pair of states. We show that it is decidable whether a given relation is a normed simulation relation, given that tautology checking is decidable. We also prove that, at the semantic level, normed simulations form a complete proof method for establishing behavior inclusion, provided that the highlevel system has finite invisible nondeterminism. As an illustration of our method we discuss the verification in PVS of a leader election algorithm that is used within the IEEE 1394 protocol. 1 Introdu...

Abstract. We define a cones and foci proof method, which rephrases the question whether two system specifications are branching bisimilar in terms of proof obligations on relations between data objects. Compared to the original cones and foci method from Groote and Springintveld [22], our method is more generally applicable, and does not require a preprocessing step to eliminate τloops. We prove soundness of our approach and give an application. 1

Studying industrial systems by simulation enables the designer to study the dynamic behaviour and to determine some characteristics of the system. Unfortunately, simulation also has some disadvantages. These can be overcome by using formal methods. Formal methods allow a thorough analysis of the possible behaviours of a system, parameterised system analysis and a modular approach to the analysis of systems. We present a case study in which a model of an industrial system is studied in a formal way. For this purpose, the model is first specified and simulated using the CSPbased executable specification language Ø. The model is translated into a model in the process algebra ACP ø . This enables us to give a correctness proof of the parameterised model and to study the model in isolation. 1. Introduction Nowadays, industry makes higher demands on methodologies used for the design of new factories. Firstly, due to the huge amount of money involved and growing competition on the market...
