Machine Learning Product Line Engineering: A Systematic Reuse Framework
Machine Learning (ML) is increasingly applied across various domains, but existing reuse practices are fragmented and ad hoc. Product Line Engineering (PLE) offers systematic reuse in traditional engineering, but isn't tailored for ML-specific assets like datasets or iterative workflows. This paper proposes Machine Learning Product Line Engineering (ML PLE), a novel framework adapting PLE principles for ML systems. ML PLE introduces a systematic, variability-aware reuse approach spanning the entire ML development lifecycle, including datasets, pipelines, models, and configuration assets. It defines key requirements and a tailored lifecycle process. An industrial case study in space systems for satellite data analytics demonstrates ML PLE's potential to improve reuse, scalability, and efficiency.

ML PLE Fundamentals
Domain & Application Engineering
Addressing ML Challenges
ML PLE extends traditional Product Line Engineering by systematically managing ML-specific core assets such as datasets, feature pipelines, models, and hyperparameters. It aligns with the dynamic, data-driven nature of ML workflows, supporting variability management and comprehensive lifecycle traceability.
- Datasets
- Pipelines
- Models
- Hyperparameters
- Variability Management
- Lifecycle Traceability
The framework separates ML development into Domain Engineering (for creating reusable core assets and variability models) and Application Engineering (for configuring and integrating these assets into specific ML products). This structured approach ensures efficient derivation of ML solutions tailored to diverse application needs.
- Domain Engineering
- Application Engineering
- Reusable Core Assets
- Product Derivation
ML PLE tackles challenges like fragmented reuse, lack of systematic variability management, and poor traceability in iterative ML workflows. It enforces metadata-driven cataloging and standardized formats for FAIR principles (Findable, Accessible, Interoperable, Reusable) across ML assets.

| Aspect | ML PLE | MLOps Platforms |
|---|---|---|
| Primary Objective | Systematic reuse and variability management across multiple ML products. | Automation, monitoring, and deployment of individual ML models. |
| Scope | Product family level. | Single model or pipeline level. |
| Focus | Asset management, product derivation, lifecycle traceability. | Continuous integration and deployment (CI/CD). |
| Abstraction Level | Strategic and architectural. | Operational implementation. |
| Variability Management | Central to the framework. | Not a primary concern. |
| Reuse Mechanisms | Core asset modularization, asset readiness levels, feature-based selection. | Pipeline reuse, model registries, environment packaging. |
| Lifecycle Coverage | Full ML lifecycle including scoping, design, configuration, monitoring. | Primarily post-training: deployment, versioning, performance monitoring. |
Space Systems Case Study: Satellite Data Analytics
The ML PLE framework was applied to an industrial case study in space systems, specifically for data analytics in satellite missions. This domain is highly data-intensive and mission-critical, providing a suitable context for systematic ML reuse.
The framework guided the development of ML components across multiple satellite missions, supporting reuse of preprocessing pipelines, data transformation workflows, and model templates. This significantly reduced redundancy and improved consistency compared to independent development per mission.
The application demonstrated ML PLE's ability to manage variability in telemetry data formats, adapt workflows to mission-specific requirements, and enhance overall scalability, maintainability, and traceability of ML solutions in complex, high-dependence environments.
