多阶段鲁棒Optimization仿射策略的最优性

Optimality of Affine Policies in Multi-stage Robust Optimization

Dimitris Bertsimas, Dan A. Iancu, Pablo A. Parrilo

摘要:

在本文中,我们证明了一类扰动仿射控制策略在一维,约束,多阶段鲁棒优化的背景下的最优性。我们的研究结果涵盖了有限的地平线的情况下,与极大极小(最坏情况)的目标,凸状态成本加上线性控制成本。我们开发了一种新的证明方法,探讨了可行的解决方案和结构的目标函数的几何属性之间的关系。除了提供一个优雅的和概念上简单的证明技术,该方法还需要非常快速的算法的情况下,分段仿射状态成本,我们探讨与经典的库存管理应用程序。

英文摘要:

In this paper, we show the optimality of a certain class of disturbance-affine control policies in the context of one-dimensional, constrained, multi-stage robust optimization. Our results cover the finite horizon case, with minimax (worst-case) objective, and convex state costs plus linear control costs. We develop a new proof methodology, which explores the relationship between the geometrical properties of the feasible set of solutions and the structure of the objective function. Apart from providing an elegant and conceptually simple proof technique, the approach also entails very fast algorithms for the case of piecewise affine state costs, which we explore in connection with a classical inventory management application.
