For modelling hybrid systems, we have extended Event B based on its framework with the differential event. The differential event describes continuous behaviors of hybrid systems by differential equations and evolution constraint, whose proof obligations provide dynamical properties of a model. In order to ensure the safety and reliability of a model, proof obligations should be proved. It is difficult...
Modeling and Analysis of Real-Time and Embedded systems (MARTE) is a profile of United Modeling Language (UML), which provides support for specification, design and verification for Real-Time Embedded Systems (RTES). MARTE sequence diagram can deal with both discrete and dense time in which a clock can be either chronometric or logical. However it lacks the ability to describe the continuous behavior...
Cyber-Physical Systems (CPSs) integrate computing, communication and control processes. Therefore, both time and space information are required in the design and modeling of CPS systems. CPS also requires demanding real time property. However, unified modeling of continuous and discrete variables is still an unsolved problem in the CPS development. In this paper we propose an extended UML state chart,...
