Surrogate duality for robust optimization

Suzuki, Satoshi; Kuroiwa, Daishi; Lee, Gue Myung - In: European Journal of Operational Research 231 (2013) 2, pp. 257-262

Robust optimization problems, which have uncertain data, are considered. We prove surrogate duality theorems for robust …

Worst-case global optimization of black-box functions through Kriging and relaxation

Marzat, Julien; Walter, Eric; Piet-Lahanier, Hélène - In: Journal of Global Optimization 55 (2013) 4, pp. 707-727

A new algorithm is proposed to deal with the worst-case optimization of black-box functions evaluated through costly computer simulations. The input variables of these computer experiments are assumed to be of two types. Control variables must be tuned while environmental variables have an...

Robust solutions of quadratic optimization over single quadratic constraint under interval uncertainty

Jeyakumar, V.; Li, G. - In: Journal of Global Optimization 55 (2013) 2, pp. 209-226

In this paper we examine non-convex quadratic optimization problems over a quadratic constraint under unknown but bounded interval perturbation of problem data in the constraint and develop criteria for characterizing robust (i.e. uncertainty-immunized) global solutions of classes of non-convex...

A joint optimal pricing and order quantity model under parameter uncertainty and its practical implementation

Lim, Sungmook - In: Omega 41 (2013) 6, pp. 998-1007

We consider a robust optimization model of determining a joint optimal bundle of price and order quantity for a … ellipsoids. We show that the robust optimization problem can be transformed into an equivalent convex optimization which can be …

Multi-criteria robust design of a JIT-based cross-docking distribution center for an auto parts supply chain

Shi, Wen; Liu, Zhixue; Shang, Jennifer; Cui, Yujia - In: European Journal of Operational Research 229 (2013) 3, pp. 695-706

We present a solution framework based on discrete-event simulation and enhanced robust design technique to address a multi-response optimization problem inherent in logistics management. The objective is to design a robust configuration for a cross-docking distribution center so that the system...

Robust weighted vertex p-center model considering uncertain data: An application to emergency management

Lu, Chung-Cheng - In: European Journal of Operational Research 230 (2013) 1, pp. 113-121

This paper presents a generalized weighted vertex p-center (WVPC) model that represents uncertain nodal weights and edge lengths using prescribed intervals or ranges. The objective of the robust WVPC (RWVPC) model is to locate p facilities on a given set of candidate sites so as to minimize...

Decision making under uncertainty in energy systems: State of the art

Soroudi, Alireza; Amraee, Turaj - In: Renewable and Sustainable Energy Reviews 28 (2013) C, pp. 376-384

The energy system studies include a wide range of issues from short term (e.g. real-time, hourly, daily and weekly operating decisions) to long term horizons (e.g. planning or policy making). The decision making chain is fed by input parameters which are usually subject to uncertainties. The art...

An inexact robust optimization method for supporting carbon dioxide emissions management in regional electric-power systems

Chen, C.; Li, Y.P.; Huang, G.H. - In: Energy Economics 40 (2013) C, pp. 441-456

In this study, an inexact robust optimization method (IROM) is developed for supporting carbon dioxide (CO2) emission … management in a regional-scale energy system, through incorporating interval-parameter programming (IPP) within a robust … optimization (RO) framework. In the modeling formulation, penalties are exercised with the recourse against any infeasibility, and …
