A value‐driven, integrated approach to Model‐Based Product Line Engineering

Abstract

Pushed to the edge of their capabilities in a highly competitive world market, organizations everywhere look for efficient means to innovate and develop their products and services. This paper proposes and illustrates a holistic integration of Product Line Engineering (PLE) and Model‐Based Systems Engineering (MBSE) to connect and align market and business analysis, architecting, design, and engineering. This value‐driven, integrated approach capitalizes on MBSE best practices to tackle the concrete challenges of product line engineering.

Tackling Optimization and System-Driven Engineering in Coupling Physical Constraints with MBSE: The Case of a Mobile Autonomous Line of Products

“…∑ 𝐹 𝑥 = 𝑀 × 𝑎 = 𝑓 − 𝑚 × 𝑔 𝑥 (8) 𝑀 × 𝑎 = 𝑇/𝑅 − 𝑀 × 𝑔 × 𝑠𝑖𝑛(θ) (9) 𝑇 = 𝑅 × 𝑀 × (𝑎 + 𝑔 × 𝑠𝑖𝑛(θ)) (10) The Torque value in (10) is the expression we modelled for one wheel. In (11), we add N as the number of wheels, which divides the torque required for the system:…”

“…While most common system engineering publications rely on MBSE and SysML 1.3 principles to provide pragmatic models [6] and to share high-level information, the inclusion of physical constraints are seldom expressed in system models. Furthermore, the processes exposed for MBPLE using variants at high level with Cameo Modeler [7] or ARCADIA/Capella [8] do not include automated connections that would take mechanical constraints impacts on system overall decisions.…”
