Contract-Based Formal Specification of Safety Critical Systems
نویسندگان
چکیده
The paper proposes an approach to light-weight formal specification for interfaces, connectors, contracts and integration of component systems based on UML 2.0 superstructure. Both of static and dynamic contracts are provided with formal models. Dynamic contract can be verified through finding a legal environment in an optimistical way for the integrated components, whose contracts are depicted with interface protocol state machines. The consistency for component refinement is also studied. These formal models form the foundation for model checking, compositional reasoning, and real-time architecture development of component-based safety critical systems.

Applying RT-Z to Develop Safety-Critical Systems
We present the application of the formal specification language RT-Z, an integration of the model-based specification language Z and the real-time process algebra timed CSP, in the area of safety-critical systems. The characteristics underlying the development of safety-critical systems are identified, and criteria for specification languages to be used in this area are derived. It is demonstra...

One of the areas with greatest needs having available information at the right moment and with high accuracy is healthcare. Right information at right time saves lives. Healthcare is a vital domain which needs high processing power for high amounts of data. Due to the critical and the special characteristics of these systems, formal methods are used for specification, description and verificati...

متن کاملData-flow Networks in the Design of Safety-critical Systems
The paper deals with practical aspects of developing control systems. We briefly discuss safety-critical systems, we examine the use of formal methods as a possible technique for increasing safety and reliability (by allowing a formal specification of the initial requirements of the system and by avoiding design errors) and we propose a design methodology for such systems based on data-flow net...
متن کاملFormal Methods in Safety-Critical Railway Systems
In this article we would like to present some recent applications of the B formal method to the development of safety critical systems, namely platform screen door controllers. These SIL3/SIL4 compliant systems have their functional specification based on a formal model. This model has been proved, guaranteeing a correct by construction behaviour of the system in absence of failure of its compo...
