题目:Convergence Analysis for Mathematical Programs with
Distributionally Robust Chance Constraint
时间:2016年7月19日,10:10—12:00
地点:理科楼407
讲座内容:Convergence analysis for optimization problems with chance constraints concerns impact of variation of probability measure in the chance constraints on the optimal value and the
optimal solutions and research on this topic has been well documented in the literature of stochastic
programming. In this paper, we extend such analysis to optimization problems with distributionally
robust chance constraints where the true probability is unknown, but it is possible to construct an
ambiguity set of distributions and the chance constraint is based on the most conservative selection
of probability distribution from the ambiguity set.
The convergence analysis focuses on impact of the variation of the ambiguity set on the optimal value and the optimal solutions. We start by deriving general convergence results under abstract
conditions such as continuity of the robust probability function and uniform convergence of robust
probability functions and followed with detailed analysis of these conditions. Two sufficient
conditions have been derived with one applicable to both continuous and discrete probability
distribution and the other to continuous distribution but different from the well known traditional
boundary condition in the literature. Case studies are carried out for ambiguity sets being
constructed through moments and samples.
