报告内容摘要:

In this talk, I will present our recent progress on how to handle decision-making optimization problems with uncertain variables. Normally, solving an optimization problem with random variables in constraints or objective function is cumbersome or even computational intractable. To better capture the fluctuant nature of random variables, we propose a flexible distribution uncertainty model. Specifically, we extract reference distributions as useful references and allow the actual distributions of the random variables to vary around their references. Such a model allows convenient handling of volatile variables as long as their profiles are not too intensely different from the predictions or empirical knowledge. We further develop chance-constraint approximation and robust optimization approaches based on the proposed uncertainty model to firstly transform and then solve the problem. The proposed method is a universal method that can be conveniently extended to handle many other decision-making optimization problems with uncertainties. We summarize the merit of the proposed framework and its applications in modeling and solving optimization problems under various scenarios in different networks (smart grid, wireless sensor networks, data centers).
