“…We can trace the origins of PLE as a distinct engineering practice back roughly to the mid-1970s, when the first works on the formalization of software product families appeared (often traced to the work of McIlroy 1976). But the formalization of this practice for its application to complex systems engineering is scarce and relatively new despite a historical, de facto, or casual reuse practice in industry, like the utilization of existing specification documents, technical drawings, or test procedures (Fortune and Valerdi 2013), and the existence of some reports on successful industrial applications (Flores et al 2013;Gregg and Clements 2016).…”

This paper presents a mid‐term return of experience from Alstom's rolling stock division on its implementation of product line engineering (PLE). It describes the journey we have undertaken to implement PLE, the challenges we have had to face, and the manner in which we are finding our way (most of the time deliberately, sometimes fortuitously) to define a profitable reuse strategy and to structure our approach on PLE. The paper also presents some encouraging intermediate results and concludes with the perspectives and the future challenges in our search for product line systems engineering excellence.

“…The number of prod- uct variants produced is in the low tens of thousands. GM is re-engineering its variability tooling to use the commercial product line tool Gears by BigLever Software 1 [14]. To help manage the complexity, product lines will be decomposed into modules corresponding to the natural divisions in the automotive system architecture to produce a hierarchical product line.…”

“…For example, modern cars use software to achieve a large variety of functionality, from power train control to infotainment. To organize and manage the huge variety of software subsystems, many car manufacturers, such as General Motors (GM), make extensive use of software product line engineering techniques [14].…”

Abstract. Software Product Lines (SPL) are widely used to manage variability in the automotive industry. In a rapidly changing industrial environment, model transformations are necessary to aid in automating the evolution of SPLs. However, existing transformation technologies are not well-suited to handling industrial-grade variability in software artifacts. We present a case study where we "lift" a previously developed migration transformation so that it becomes applicable to realistic industrial product lines. Our experience indicates that it is both feasible and scalable to lift transformations for industrial SPLs.

“…The need for variability among various subclasses of related products adds another dimension to this complexity-it is typical for large automotive manufacturers to build and sell millions of vehicles world-wide with different vehicle types, brands, and options under varying regulatory and legal requirements. In order to cope up with complexity and variability at such scale, automotive manufacturers are turning toward product line engineering approach [7]. Product line engineering approach is a framework to develop products family rather than individual products.…”

Modern automotive systems are composed of hundreds of software-implemented features often interacting with physical subsystems under real-time constraints. For efficient management of their development, the features are conceived and realized as product lines involving variability with different variants being deployed in different vehicle classes. The variability information is expressed at different levels of abstraction during the various phases of development, like requirements, design and implementation. We introduce and study a formal model of such feature product lines capable of capturing variability and real-time behavior. We define a notion of conformance to relate the variability at different levels of abstraction and propose a compositional method of verifying conformance of multiple features. The proposed approach naturally extends to hybrid system behaviors consisting of discrete and continuous plant variables. We demonstrate the applicability of the approach by giving a simple paradigmatic example.
