Towards biogas purifier supply chain resilience
Context and Challenges
France heavily relies on natural gas imports, highlighting the importance of biomethane as a sustainable alternative. Biomethane production depends on large-scale biogas upgrading platforms, characterized by an Engineer-to-Order (ETO) system, with lead times of approximately one year and a complex supply chain involving numerous specialized suppliers and subcontractors. The I-Démo Alliance project aims to develop an industrial supply chain capable of meeting increasing demand, with the goal of increasing production capacity from 150 to 450 units per year. This project is carried out in collaboration with the companies Prodeval and Aventech, as well as the DISP laboratory.
Research Question
How can a methodological approach be developed to model a supply chain that enables demand ramp-up while maintaining resilience against potential disruptions?
Scientific Challenges
- Identify the characteristics of the biogas upgrading systems' supply chain to extract key elements that ensure the system's capacity to absorb increased demand while maintaining resilience.
- Design a decision-support tool for the supply chain to analyze and propose strategies that guarantee the system's viability and resilience under various ramp-up scenarios.
- Validate the proposed strategies through numerical experiments to evaluate their performance in terms of resilience capacity at different levels.
Results
- Development of a linear model to study the supply chain's capacity.
- Identification of indicators for assessing the supply chain's capacity, such as the workload of production and supply resources.
- Design of an iterative experimentation methodology in a ramp-up context, testing different demand profiles and product mixes.
- Validation and refinement of the mathematical model with companies.
