Abstract: Raising healthy life expectancy is an urgent issue in super-ageing societies. To promote people's health at national and municipal levels, a social system is needed to achieve behaviour change. This study conducted an indepth system design of a novel behavioural change platform (BCPF) service that promotes behavioural changes through the support of the surroundings. First, to identify the system associated with each service provider in the BCPF service, the authors analysed Level 2 diagrams using the object process methodology. Second, customer value chain analysis was performed to visibly and logically identify primary stakeholders and value streams. Finally, to describe the dynamic behaviour of BCPF service, system dynamics simulation was conducted. Through a comprehensive examination of the relationships between parameters sensitive to the number of BCPF service users, the analysis revealed the number of users can increase to more than 10% of the total population within three years.
