During period 2, SC4EU continued active development and coordination towards the Digital Reference ecosystem and the asso-ciated user administration processes. IFAG led and moderated regular meetings, ensuring that all bene-ficiaries’ efforts were effectively aligned and integrated across the work package. Progress was made in expanding the ecosystem's technical capabilities and collaboration between partners, although the complexity of several tasks led to necessary extensions and adjustments to initial planning. The OCP was significantly expanded with new and enhanced features. The vocabulary development environment now includes the Ontology Development Tool (OnDeT), which visualises the evolution of project terminology over time and is available for all ontologies registered in the OCP. The consensus tool was introduced to support controlled terminology maturation.
The planning ontology from the previous SC3 project was extended and refined towards a demand fore-casting ontology. New concepts, predicates, and agent activities in addition to the artifacts from the planning ontology were incorporated into the proposed forecasting ontology. The final version of the forecasting ontology was implemented in the Protégé tool. We also initiated to work on methods using the WSTS dataset and company-specific historical demand data from IFAG to forecast the IFAG demand based on the WSTS data. The System Dynamics (SD) model was further extended and refined. A model to predict lot completion times in wafer fabs was implemented and tested in the reporting period.
Significant results have been achieved concerning the specification and requirements for the survey use case. A substantial amount of dialogue has taken place among the project partners, focusing on clarifying the specifics of the survey questions. Given that different surveys are designed for each tier of the supply chain, the project partners have collaboratively discussed and tailored questions to meet the distinct needs of each tier. The development of the questions for the semiconductor manufacturers, the Tier-1 suppliers and the OEMs is completed and a successful first complete survey run has been conducted. Six survey types (SEMI, OEM, TIER 1, monthly/yearly) are now operational. Analysts can select survey templates that automatically configure the questions, MPC operations, and corresponding Excel import features connected to WP5 transformation files, ensuring privacy compliant data uploads.
In the first half of 2025 the “semi” survey questions were finalized within WP5. It was decided to cover the survey’s questions demand with the future sales & marketing forecasts, inventory, and order can-cellations, with a focus on technology nodes as dimension for the question. Next steps of WP5 is finish-ing the definition of the OEM questionnaire specification and shift the focus then to the Tier1 survey and the transformation graph between the semiconductor products. For the OEM survey the automotive market has been selected.
