Formal Analysis of Concurrent Real-Time Requirements Models
نویسندگان
چکیده
This report demonstrates the use of modal and temporal logic to analysis the functional and safety requirements of concurrent real-time systems. Our research is based on the integrated method: Hazard and Operability Studies; Ward and Mellor Essential Models; and the Temporal Calculus of Communicating Systems to model and analyse real-time control systems. In particular, we discuss the interplay between traditional hazard analysis techniques and formal methods and their associated analyses in the context of an integrated model. The approach is illustrated by a small but realistic industrial case study.

Integrated Architectural Modeling of Real-Time Concurrent Systems with Applications in FMS
A Real-time Architectural Specification (RAS) model and its application in the modeling of flexible manufacturing system (FMS) are presented. An FMS is a typical real-time concurrent system composed of a number of computer-controlled machine tools, automated material handling and storage systems that operate as an integrated system under the control of host computer(s). The growing demand for...
متن کاملReachability checking in complex and concurrent software systems using intelligent search methods
Software system verification is an efficient technique for ensuring the correctness of a software product, especially in safety-critical systems in which a small bug may have disastrous consequences. The goal of software verification is to ensure that the product fulfills the requirements. Studies show that the cost of finding and fixing errors in design time is less than finding and fixing the...

متن کاملFormal Modeling and Analysis of AADL Threads in Real Time Maude
This paper presents, without altering the AADL meta-model, a formal description of static and behavioral aspects of the AADL thread component. This active and concurrent applicative component of AADL poses many challenges to its formalization and analysis including instantaneous and/or delayed communications, concurrent tasks and timedependent features, and the need to analyze correctness. This...
متن کاملA topological formal treatment for scenario-based software specification of concurrent real-time systems
Abstract: Real-time systems are computing systems in which the meeting of their requirements is vital for their correctness. Consequently, if the real-time requirements of these systems are poorly understood and verified, the results can be disastrous and lead to irremediable project failures at the early phases of development. The present work addresses the problem of detecting deadlock situat...
