....parallel composition are essentially a kind of logical conjunction, and are integrated seamlessly. Furthermore, there is tool support available for CSP, in particular there is the model checker FDR (Failures Divergence Refinement) Ros94] There will be a translation tool for CSP OZ to FDR soon [FiWe99, Wir99] and there exists alread a type checking tool [vG99] CSP OZ has been developed recently at the University of Oldenburg. In the appendix of this report, we present a case study in CSP OZ that is the translation of a part of the case study of [Bre98b] which we specified in Functional ....

More tool support will be available until the end of 1999: ffl the model checker FDR with a translation from CSP OZ to the language of FDR This translation [FiWe99, Wir99] will enable us to validate arbitrary safety properties of CSP OZ specifications, through the commercial model checking tool FDR [Ros94] which is available for CSP. The validation will be restricted, of course, by the size of the complete transition graph which FDR constructs. Also, a few ....

....we will be concerned with verifying CSP OZ specifications. The first step in the verification of a given CSP OZ specification will be a translation into CSP 1 , to be precise, into the CSP dialect of the model checker FDR (Failure Divergence Refinement [9] This technique has been proposed in [8], extending previous ideas of [16, 19] to use FDR to check properties of (CSP )Z specifications. FDR CSP is a combination of CSP with a functional language in the style of Haskell and Miranda. The functional language can be used to encode the Z data descriptions. Due to the possibly large data ....

....2 Prerequisites We start with a brief description of CSP OZ and the specific structure of the translated specifications. The data abstraction techniques we suggest are tailored towards this specific structure. The translation will be explained through an example, details can be found in [8]. Afterwards we briefly describe the semantics underlying the process algebra CSP. A summary of CSP operators can be found in the appendix, a more detailed introduction in [11] 2.1 CSP OZ CSP OZ is an integrated formal method that allows for a description of static aspects (by means of ....

....(in the sense of message exchanges via channels) An advantage of using formal methods in the specification of software is their precise formal semantics. This advantage can best be exploited when some property checking on the specification can also be performed. Using a technique proposed in [FW99] translating CSP OZ specifications into the input language of the CSP model checker FDR [FDR97] we carry out some correctness checks on the specification, most notably a check for deadlock freedom. Given the complex communication protocol among machine tools and transportation agents, ....

....for interaction. The communication scheme of a system is the major source for errors leading to deadlocks of the system. In the next section, we describe how we can prove deadlock freedom of our specification. 4 Verification The verification of the manufacturing system follows ideas proposed in [FW99] (building on ideas of [MS98] the CSP OZ specification is translated into the CSP dialect of the model checker FDR [FDR97] which can then be used to verify properties on the specification. The formal basis for this translation is the failure divergence semantics of CSP OZ classes. The CSP ....

....of these two worlds. It is a wide range specification language for complex distributed systems like telecommunication, satellite, or rail road systems. CSP OZ has powerful methods for building provably correct systems: like transformation rules and data refinement [FH97] or model checking support [FW99] In principle, it is also possible to transform CSP OZ specifications into code. However, all these tasks require expertise in using formal methods and tools and require often significant interaction. This problem holds for many formal methods and limits the chance for industrial success ....
