A cyber-physical system (CPS), that is to be used a safety important system, needs to analyze the traceability of development artifacts. The traceability analysis of the CPS should be performed integrating development artifacts and safety/hazard analysis elements because CPS has several features such as heterogeneity, dynamic reconfiguration, and interoperability. However, there is a limitation in terms of expressing all traceability relationships by identically connecting and analyzing the traceability between development artifacts and safety analysis elements. This paper proposes an analysis method and relationships of traceability for CPS. The proposed method uses an abstract model for development artifacts and safety analysis elements that are defined in this paper. The traceability relationships define the relations between elements of the model. The proposed method makes it possible to analyze integrated relationships from development artifacts and safety/hazard analysis elements. The case study shows integrated relationships according to each element of several artifacts.
OSDEF: An Integrated Framework for Practicing Object-Oriented Software Development
http://doi.org/10.5626/JOK.2019.46.8.774
Software development starts with a specific software development process (SDP) which contains the start and end of the development, SDP plays an important role in the software engineering education. Object-oriented software development education uses several examples that contain object-oriented characteristics into education and practices. However, there is an immense burden on the implantation phases as per the scale of the program, thus creating difficulties in the identification of the connected relations between software design and implementation. In the present work, we propose the OSDEF (Object-oriented based Software Development Education Framework) framework for proceeding an efficient software engineering education based on the OOPT (Object-Oriented Process with Traceability). The framework contains artifact management tools which can directly write development artifacts inside the tool, traceability analysis tool, and emulating environment for embedded software, which can practice a layered architecture in an efficient manner.
OOPT: An Object-Oriented Development Methodology for Software Engineering Education
Sejin Jung, Dong-Ah Lee, Eui-Sub Kim, Chun-Hyon Chang, Junbeom Yoo
The software development process (SDP) plays an important basic role in software engineering education. Every software is developed in accordance with a specific SDP which contains all phases of software development. SDP education helps students to understand the overall techniques and the process of software engineering. This paper introduces a software development methodology (i.e., process) - ‘OOPT (Object Oriented Process with Traceability),’ which was proposed for use in university software engineering classes. The OOPT is based on object-oriented software development, and it defines concrete requirements as well as outputs of each process/phases. It also contains the unit/system testing and a traceability analysis. We have used the OOPT in software engineering classes at Konkuk university for eight years. This paper conveys our experience as well as future extension and improvement plans.
