Title: Data-driven approach to demand dispatching for emerging on-demand servicesAbstract
Recent on-demand services, such as Uber and GoGoVan in Hong Kong, provide a platform for users to request services on the spot and for suppliers to meet such demand. Future energy systems can also be considered as on-demand services, as multiple suppliers compete to satisfy energy demand from their customers. In this talk, I will describe the fundamental problem of demand dispatching in these emerging on-demand services, with the objective of maximizing supplier profits and saving user costs. Due to the autonomy of the suppliers, traditional optimization approaches are no longer applicable. We adopted a data-driven approach, the upshot of which is that the time-varying pattern of the supply-demand distribution and the pattern of suppliers in accepting user demand can be predicted using historical service data, and such predictions can be used online algorithms to optimize demand dispatching in terms of response times and service costs. I will focus on real-world scenarios in the GoGoVan system, an online logistic platform providing shipping services to customers in Hong Kong.Short Bio
