The P4S Team of Lab-STICC & ENSTA Bretagne are proud to be a partner of the OneWay project, led by Airbus and supported by DGAC (the French Civil Aviation Authority), which aim to ensure digital continuity in the aeronautical sector. OBP2 plays an important role in the verification of the Product Development Plans expressed in BPMN.
Modeling Capabilities and Digital Analysis of a Product Development Plan
Against a fiercely competitive global economic backdrop, the aeronautical industry is one of France’s strengths. With a fabric of small, medium and large companies, the French aeronautics sector is the only one, along with the United States, that is fully capable of developing, producing and marketing civil and military aircraft. The French Government has developed a plan for supporting the aeronautics sector, designed to protect French expertise and know-how, while delivering the far-reaching changes needed to achieve the energy transition. The strategy is focused on the green transition and lowering carbon emissions in air transport.
The French aeronautical industry’s expertise on its products, programs and interactions within its value chain is widely recognized. For all that, it must contend with a growing number of challenges if it is to become more proficient in its design and development cycles and more efficient in its engineering activities and ensure that the performances of its products and support systems continually improve. It also needs to take technological innovations more swiftly on board and take advantage of the opportunities offered by new information technologies. Given these challenges, there is an inevitable need for radical changes to engineering methods within the French aeronautical industry, and this is where the ONEWAY project comes in.
The project began in May 2021, for an 18-month period, with a budget of €48m. It brought together 14 partners: Airbus, Dassault Aviation, Liebherr Aerospace, Safran Electrical & Power, Safran Aerotechnics, Thales, Altran Technologies, Cap Gemini, Sopra Steria, CIMPA, PragmaDEV, IMT Mines Ales, Université de Rennes 1 and ENSTA Bretagne.
ENSTA Bretagne helps to define a digital capacity for supporting decisions regarding launch, then control and management of a Product Development Plan (PDP). The PDP seeks to predict and control the best date for a product and its industrial system to be brought to the market, as well as the expected production ramp-up stage. This has become crucial for the competitiveness of the French aeronautical industry.
Thanks to the experience of ENSTA Bretagne’s Processes for Safe and Secure Software and Systems (P4S) team on federating complex software systems, the development of formal semantics and analytical algorithms, an equipped PDP modeling framework has been established. The tool developed allows for a detailed capture of the business specifics, industrial-scale simulation of the development process and validation of the models built through formal verification methods.
For ENSTA Bretagne, the two main implications in the ONEWAY project concern the formal verification and validation of the PDP. Project outcomes:
- Extension of the OBP2 model-checker with statistical exploration algorithms for massive testing on industry-derived models;
- Improvement of the layer of expression of formal properties associated with the system requirements or Top Program Objectives;
- Invention of a modular strategy for the formal verification of time-bound systems, based on the PDP’s formal semantics without the need for costly model transformation procedures.
