The next big challenge for SMEs will be to implement the dual (or twin) transformation in sense of a digital transformation towards more intelligent manufacturing, while tackling and accelerating the
sustainability transformation to enhance economically, socially and environmentally sustainable processes, factories and value chains.
This project aims to take SMEs to this next level by developing a Strategic Roadmap for making them not only intelligent but also
sustainable, resilient and human-centric. This next level of SMEs will be data and intelligence-driven, thus using available data to
acquire new knowledge and to apply it for optimization purposes using artificial intelligence in a secure way. Further, a great
attention is paid to how manufacturing and value chains in SMEs can become more circular, green and resilient. The main outcome of the project is to develop and propose a Strategic Guideline and Roadmap that will facilitate SMEs in Europe and worldwide to achieve the above mentioned goals.
