This paper introduces a new notation called S which is based on higher order logic. It has been developed specifically to support the practical application of formal methods in industrial scale projects. The development of S has occurred in the context of an investigation into the possibility of using formal specification techniques in the development of a $400 million air traffic control syste...

A Real-Time Architectural Specification (RAS) approach and its application to command and control (C2) systems are presented. The objective is to establish a formal foundation that will enable us to integrate existing rich but fragmented formal techniques for system specification and verification into practical and scaleable formal engineering methods to support the design and development of hi...

Tool support is known to be one of the success factors in formal specification based analysis and -program development. This paper investigates tool support in the context of a case study where a wide range of tool features is required: For an access control, C++ code has to be developed based on the user’s requirements expressed in natural language. The access control has been classified a mix...

Formal methods are usually used for computer system specification, production and verification. In this paper, a new direction for the use of formal methods is proposed, namely formalization of the regulatory requirements for software of safety-critical control systems. Formal regulatory requirements, as opposed to formal specifications for a concrete system, have a generic nature, are applicab...

OSEK/VDX, a standard of automobile OS, is proposed to support the development of high-quality automotive applications. With its widely adopted, more and more automotive applications have been developed based on OSEK/VDX OS. As the continuously increasing complexity in the development of applications, how to efficiently develop an application is becoming a challenge. A primary problem is the req...

The mission system of an aircraft is a complex real-time distributed system consisting of a mission control computer, different kinds of devices interconnected by a number of serial data buses. The complexity and real-time requirements of mission systems have motivated research into the application of formal techniques to investigate and predict the effects of upgrades on mission system behavio...
