Compromising system and user interests in shelter location and evacuation planning
(Elsevier Ltd, 2015)Traffic management during an evacuation and the decision of where to locate the shelters are of critical importance to the performance of an evacuation plan. From the evacuation management authority's point of view, the ... 
Computational methods for riskaverse undiscounted transient markov models
(Institute for Operations Research and the Management Sciences (I N F O R M S), 2014)The total cost problem for discretetime controlled transient Markov models is considered. The objective functional is a Markov dynamic risk measure of the total cost. Two solution methods, value and policy iteration, are ... 
Computationally efficient optimization of stock pooling and allocation levels for twodemandclasses under general lead time distributions
(Taylor and Francis Ltd., 2016)In this article we develop a procedure for estimating service levels (fill rates) and for optimizing stock and threshold levels in a twodemandclass model managed based on a lotforlot replenishment policy and a static ... 
Computing minimumvolume enclosing axisaligned ellipsoids
(Springer, 2008)Given a set of points S = {x1 ,..., xm}⊂ ℝn and ε>0, we propose and analyze an algorithm for the problem of computing a (1+ε)approximation to the minimumvolume axisaligned ellipsoid enclosing S. We establish that our ... 
Concentrator location in telecommunications
(Springer, 2004)We survey the main results in the author's PhD Thesis presented in December 2002 at the Université Libre de Bruxelles and supervised by Prof. Martine Labbé. The dissertation is written in English and is available at ... 
Concurrent consideration of product design, process planning and production planning activities
(1998)In manufacturing engineering, product design, process planning and production planning activities are often considered independently. However, in order to effectively respond to changes in business situations, such as ... 
A Conic Integer Programming Approach to Constrained Assortment Optimization under the Mixed Multinomial Logit Model
(Institute for Operations Research and the Management Sciences (INFORMS), 20170812)We consider the constrained assortment optimization problem under the mixed multinomial logit model. Even moderately sized instances of this problem are challenging to solve directly using standard mixedinteger linear ... 
Considering manufacturing cost and scheduling performance on a CNC turning machine
(Elsevier, 2007)A well known industry application that allows controllable processing times is the manufacturing operations on CNC machines. For each turning operation as an example, there is a nonlinear relationship between the manufacturing ... 
Constrained nonlinear programming for volatility estimation with GARCH models
(2003)This paper proposes a constrained nonlinear programming view of generalized autoregressive conditional heteroskedasticity (GARCH) volatility estimation models in financial econometrics. These models are usually presented ... 
Constrained optimal hybrid control of a flow shop system
(Institute of Electrical and Electronics Engineers, 2007)We consider an optimal control problem for the hybrid model of a deterministic flow shop system, in which the jobs are processed in the order they arrive at the system. The problem is decomposed into a higherlevel ... 
Continuation method for nonlinear complementarity problems via normal maps
(Elsevier, 1999)In a recent paper by Chen and Mangasarian (C. Chen, O.L. Mangasarian, A class of smoothing functions for nonlinear and mixed complementarity problems, Computational Optimization and Applications 2 (1996), 97±138) a class ... 
Continuous knapsack sets with divisible capacities
(Springer, 2016)We study two continuous knapsack sets (Formula presented.) and (Formula presented.) with (Formula presented.) integer, one unbounded continuous and (Formula presented.) bounded continuous variables in either (Formula ... 
A continuous review replenishmentdisposal policy for an inventory system with autonomous supply and fixed disposal costs
(Elsevier, 2008)In this study, we analyze an inventory system facing stochastic external demands and an autonomous supply (independent return flow) in the presence of fixed disposal costs and positive lead times under a continuous review ... 
Contracting under uncertain capacity
(Inderscience publishers, 2010)In this paper, we develop a twostage supplychain in which a supplier with uncertain capacity sells to a retailer facing a Newsvendor problem. We analyze the centralized system where both partners take their decisions ... 
Contractual agreements for coordination and vendormanaged delivery under explicit transportation considerations
(John Wiley & Sons, 2006)We consider the coordination problem between a vendor and a buyer operating under generalized replenishment costs that include fixed costs as well as stepwise freight costs. We study the stochastic demand, singleperiod ... 
Convergence of switching reward processes
(American Mathematical Society, 2001)We study the convergence in the Skorokhod Jtopology of switching reward processes constructed by sums of conditionally independent random variables or by processes with conditionally independent increments on the trajectories ... 
Convex hull results for the warehouse problem
(Elsevier B.V., 2018)Given an initial stock and a capacitated warehouse, the warehouse problem aims to decide when to sell and purchase to maximize profit. This problem is common in revenue management and energy storage. We extend this problem ... 
Convexity and logical analysis of data
(Elsevier, 2000)A Boolean function is called kconvex if for any pair x,y of its true points at Hamming distance at most k, every point "between" x and y is also true. Given a set of true points and a set of false points, the central ... 
Coordinated inventory replenishment and outsourced transportation operatoins
(Elsevier, 201410)We consider a onewarehouse N retailers supply chain with stochastic demand. Inventory is managed inhouse whereas transportation is outsourced to a 3PL provider. We develop analytical expressions for the operating ... 
Coordinated logistics: replenishment with capacitated transportation for a supply chain
(POMS, 201401)In this study, we consider the integrated inventory replenishment and transportation operations in a supply chain where the orders placed by the downstream retailer are dispatched by the upstream warehouse via an inhouse ...
