Real-Time Model Checking Is Really Simple
نویسنده
چکیده
It is easy to write and verify real-time specifications with existing languages and methods; one just represents time as an ordinary variable and expresses timing requirements with special timer variables. The resulting specifications can be verified with an ordinary model checker. This basic idea and some less obvious details are explained, and results are presented for two examples.

متن کاملFormal Method in Service Composition in Heath Care Systems
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 کاملModel-Checking of Specifications Integrating Processes, Data and Time
We present a new model-checking technique for CSP-OZ-DC, a combination of CSP, Object-Z and Duration Calculus, that allows reasoning about systems exhibiting communication, data and real-time aspects. As intermediate layer we will use a new kind of timed automata that preserve events and data variables of the specification. These automata have a simple operational semantics that is amenable to ...
متن کاملSpecifying and Analyzing Real-Time Object Systems in Real-Time Maude
Society is becoming increasingly dependent on large and complex software systems whose malfunctioning could have serious consequences. However, the size and complexity of modern software systems make it almost impossible to avoid errors in their (requirements and design) specifications. In fact, it seems that errors in specifications occur at least as frequently as errors in program code and ar...
متن کاملUniversitet Statistical Model Checking in
Statistical model-checking is a recent technique used for both verification and performance analysis of hybrid systems. It does not suffer from decidability issues or state-space explosion compared to traditional model-checking. Furthermore, it is applicable to more powerful formalisms such as stochastic hybrid automata. Its principle is simple so how simple is it really to make it work in prac...
