How to Boost Product Line Engineering with MBSE - A Case Study of a Rolling Stock Product Line

Abstract

Abstract. This paper presents the first results of current product line engineering efforts at Alstom Transport. It describes the background that has led us to these efforts as well as the approach that we have adopted on Model-Based Systems Engineering (MBSE) and Product Line Engineering (PLE). We present a real-life application of MBSE and PLE that "goes beyond" SysML along with a quick overview of the first results stemming from this application to Rolling Stock systems.

Model-based systems engineering with requirements variability for embedded real-time systems

“…In addition, orthogonal variability documentation only handles variants on its diagram, and is linked with commonality models or artefacts. It has attracted a lot of attention in recent publications [12] [21], because it does not require changing the complexity of development artefacts and can be combined with different development artefacts [20]. For this classification, most recent efforts, such as the Orthogonal Variability Modelling (OVM) [22] (which was adopted as ISO/IEC standard #26550 in 2013) are examples.…”

“…This modelling tool was selected not only because of the successful cases of using it reported in the industrial paper by H. G. C. Góngora, M. Ferrogalini and C. Moreau [21], but also because it is based on ISO/IEC standard #26550 [46]. The core of this standard is OVM, an extension of which the proposed method is based on.…”

Where the big bucks (will) come from – Implementing Product Line Engineering for Railway Rolling Stock

“…Different Strokes for Different Folks. When analyzing the reuse practices in place in different areas of the organization, we identified three main approaches or "generations" of reuse (Chalé Góngora et al 2014): basic reuse (or opportunistic reuse), second generation reuse and third generation reuse (or strategic reuse). These approaches basically differ from each other by the level of maturity and the deepness of understanding of the PLE paradigm.…”

“…For the formalization of our product families, a second generation reuse strategy -including requirements databases, operational concept documents, verification and validation plans, train system architectures and the variability of the product family-was implemented. Figure 7 shows the environment that supports this reuse strategy (Chalé Góngora et al 2014). Our first implementations of the second generation reuse strategies differed slightly from the originally planned strategy explained above.…”

Model-based systems product line engineering with physical design variability for aircraft systems

“…The author Queiroz [10] proposed a systematic review on developing Critical Embedded Systems with PLE in 2014. Dumitrescu [11] and Góngora [12] both introduced methods to combine SPLE with Model-Based System Engineering (MBSE) in an industrial context. While Software Product Line Engineering is important in the systems domain, System Engineering is a much broader discipline; it includes the consideration of hardware aspects (mechanical and electrical engineering) as well as the overall integration of hardware and software components (for cyber-physical systems) [13].…”
