Random sets and Choquet-type representations
Çağın Ararat, Umur Cetin
As appropriate generalizations of convex combinations with uncountably many terms, we introduce the so-called Choquet combinations, Choquet decompositions and Choquet convex decomp…
Decomposable sums and their implications on naturally quasiconvex risk measures
Çağın Ararat, Barış Bilir, Elisa Mastrogiacomo
Convexity and quasiconvexity are two properties that capture the concept of diversification for risk measures. Between the two, there is natural quasiconvexity, an old but not so w…
End-of-Life Inventory Management Problem: Results and Insights
Emin Ozyoruk, Nesim K. Erkip, Çağın Ararat
We consider a manufacturer who manages the end-of-life phase and takes one of the three actions at each period: (1) place an order, (2) use existing inventory, (3) stop holding inv…
Constructive covers of a finite set
Çağın Ararat, Ülkü Gürler, M. Emrullah Ildız
Given positive integers with , we consider the number of ways of choosing subsets of in such a way that the union of these subsets gives $\{1,\l…
Multi-objective risk-averse two-stage stochastic programming problems
Çağın Ararat, Özlem Çavuş, Ali İrfan Mahmutoğulları
We consider a multi-objective risk-averse two-stage stochastic programming problem with a multivariate convex risk measure. We suggest a convex vector optimization formulation with…
