3.7 Modelling uncertainty, fuzzy situations and Grey Methodologies

View More

   The development of technology is enabling novel interaction platforms such as the social media in Internet.  At the same time, through investment, policies and regulations, society can enforce or prevent the development of specific technologies. Uncertainty plays a significant role in these changes. The interactions between technology and people in society are indeed complicated and traditional mathematical systems have no capacity to model them. Alternative systems are necessary to model such interactions, among them, data-driven models are gaining momentum.  With the increased availability of data from Internet and the Internet of things (IOT), big data technology is the current focus for such developments.  However, uncertainty in systems mean that the historical data cannot reflect recent changes of policy or other environment factors, and the only reliable data is likely to be real time data rather than historical big data.  And, of course unexpected uncertainty can always surprise us in modelling.  Therefore, effective modelling, maximising the use of available meaningful, albeit limited data, recognising uncertainties is essential in our big data age. Among others, the theory of grey systems does provide exactly such a facility.  Here, this session, wants to highlight the role of grey systems; this debate will focus mainly on the two extremes: big data and limited data, certainty and uncertainty.”
