Stability radius bounds for the lexicographic optimum of the vector boolean problem with Savage’s risk criteria
Abstract:
We consider a lexicographic Boolean problem of building an investor's portfolio of assets. The goal is to minimize risks using Savage's “bottleneck” (the worst-case regret) criteria. We obtained lower and upper attainable bounds for the stability radius of the lexicographic optimum of the problem in the case with octahedral metric$l_1$ in the portfolios space and Chebyshev metric$l_\infty$ in the risk and financial market conditions space.
