Abstract
Transposing the notion of software frameworks to the abstraction level of formal specifications and verifications, we developed a framework supporting the formal hazard analysis of chemical plants. It provides generic specification modules for the description of safety properties, specifica-tion modules for the description of plant models, and theo-rems stating that certain subsystem structures of the plant model imply certain safety properties. Using the framework for hazard analysis, one firstly describes the plant and its control equipment as a composition of framework module instances. Secondly, one expresses the different safety prop-erties of interest by parameterized framework modules. Fi-nally, a safety property is proven when an appropriate the-orem instance of the framework can be found. Thus, the framework facilitates the formal modeling. Moreover, the efforts for formal verifications are reduced drastically since framework theorem instances can replace explicit proofs. The framework utilizes modular temporal logic spec-ifications supported by the specification language cTLA which is a variant of Lamport’s temporal logic of actions TLA and in particular is devoted to the compositional de-scription of process systems. 1
