Can we rely on Formal Methods?e systems is obviously a matter of concern to those involved in building or using such systems. We can also agree that there is a major gap between the reliability levels that are required of these systems and those that are obtainable using traditional hardware and software design methods. The basi

A Role for Formal Methodistssystem satisfies a non-trivial specification requires a large proof. Without mechanical support, building or checking such a proof is not practical. Even with mechanical support, designing a large proof is at least as difficult as designing a large program. We are barely up to the task of building l

Toward a Multilevel-Secure, Best-Effort Real-Time Scheduler the data. The conflicts between computer security requirements and timeliness requirements are described in the context of large, distributed, supervisory-control systems that are intended for use in such critical missions. The Secure Alpha[3] approach to addressing these conflicts is introduced..

Typically, there are no established formal procedures for monitoring the progress of the design during the implementation phase, the interval between the review and approval of the “paper” design and the
