| Abstract | Critical Real-Time Systems (RTS) have strong requirements concerning system's reliability. UML and its profile MARTE are standardized modeling languages widely accepted by industrial designers to cope with the development of complex RTS. Relying on Model-Driven Engineering (MDE), time properties verification of UML-MARTE specifications at early phases of the system lifecycle becomes possible. A key issue is to eliminate the gap between UML semi-formal semantics and fully formal executable semantics using model transformation. The model transformation must guarantee the consistency between high-level user models and lowerlevel verification models. Meanwhile, it should guarantee that the subsequent verification is not too expensive and can be applied to real size industrial models. This paper presents an approach to translate UML-MARTE Activity Diagrams into Time Transition System (TTS) with the aim of efficiently verifying time properties in RTS. TTS is a generalization of Time Petri Nets (TPN) with the priority and data handling at the transition level, supported by TINA model checker. This contribution focuses on how to define the TTS formal semantics to avoid the core problem of state space explosion in model checking. This work has been integrated in a time properties verification framework for UML-MARTE RTS specifications. The proposed method is evaluated using a representative case study. Experimental results are given to demonstrate the method's performance. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
