Abstract With the emerging energy demand, water shortage in rural areas, electric supply challenges, and urgent needs for net zero technologies, there has been a recent response with alternative Hydro-Powered Pumping (HPP) technology, known as Bunyip. The recently developed system continues to build commercial success, designed overcome several limitations associated previous technology of Hydr...

In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data. Epistemic uncertainty is represented using two approaches: (1) moment bounding approach and (2) likelihood-based approach. This paper first proposes a ...
