The role of repair strategy in warranty cost minimization: An investigation via quasi-renewal processes
(Elsevier, 2009-09-01)Most companies seek efficient rectification strategies to keep their warranty related costs under control. This study develops and investigates different repair strategies for one- and two-dimensional warranties with the ... -
A simple duality proof in convex quadratic programming with a quadratic constraint, and some applications
(Elsevier, 2000-07-01)In this paper a simple derivation of duality is presented for convex quadratic programs with a convex quadratic constraint. This problem arises in a number of applications including trust region subproblems of nonlinear ... -
Sharpe-ratio pricing and hedging of contingent claims in incomplete markets by convex programming
(Elsevier, 2008-08)We analyze the problem of pricing and hedging contingent claims in a financial market described by a multi-period, discrete-time, finite-state scenario tree using an arbitrage-adjusted Sharpe-ratio criterion. We show that ... -
A global error bound for quadratic perturbation of linear programs
(Elsevier, 2002-04)We prove a global error bound result on the quadratic perturbation of linear programs. The error bound is stated in terms of function values. -
A joint production and transportation planning problem with heterogeneous vehicles
(Palgrave Macmillan, 2014-05)We consider a manufacturer's planning problem to schedule order production and transportation to respective destinations. The manufacturer in this setting can use two vehicle types for outbound shipments. The first type ... -
Temperature dependent flow softening of titanium alloy Ti6Al4V: An investigation using finite element simulation of machining
(Elsevier, 2011-04-01)Titanium alloy Ti6Al4V is the most commonly used titanium alloy in the aerospace and medical device industries due to its superior properties. There has been a considerable amount of research to better understand the ... -
Min-degree constrained minimum spanning tree problem: New formulation via Miller-Tucker-Zemlin constraints
(Elsevier, 2010-01)Given an undirected network with positive edge costs and a positive integer d > 2, the minimum-degree constrained minimum spanning tree problem is the problem of finding a spanning tree with minimum total cost such that ... -
Buyer's quantile hedge portfolios in discrete-time trading
(Taylor & Francis, 2013)The problem of quantile hedging for American claims is studied from the perspective of the buyer of a contingent claim by minimizing the ‘expected failure ratio’. After a general study of the problem in infinite-state ... -
Optimal multi-period consumption and investment with short-sale constraints
(Elsevier, 2014-03)This article examines agents' consumption-investment problem in a multi-period pure exchange economy where agents are constrained with the short-sale of state-dependent risky contingent claims. In equilibrum, agents hold ... -
Hard turning with variable micro-geometry PcBN tools
(Elsevier, 2008)This paper presents investigations on hard turning with variable edge design PcBN inserts. Turning of hardened AISI 4340 steel with uniform and variable edge design PcBN inserts is conducted, forces and tool wear are ... -
Lot sizing with piecewise concave production costs
(INFORMS, 2014-01-11)We study the lot-sizing problem with piecewise concave production costs and concave holding costs. This problem is a generalization of the lot-sizing problem with quantity discounts, minimum order quantities, capacities, ... -
A strong conic quadratic reformulation for machine-job assignment with controllable processing times
(Elsevier, 2009-05)We describe a polynomial-size conic quadratic reformulation for a machine-job assignment problem with separable convex cost. Because the conic strengthening is based only on the objective of the problem, it can also be ... -
Receding Horizon Control of Mixed Line Flow Shop Systems
(Springer, 2011-03)We consider reliable mixed line flow shop systems that are composed of controllable and uncontrollable machines. These systems are assumed to receive arrivals at random instants and process jobs deterministically in the ... -
Non-cooperative joint replenishment under asymmetric information
(Elsevier, 2013-06-16)We consider jointly replenishing n ex-ante identical firms that operate under an EOQ like setting using a non-cooperative game under asymmetric information. In this game, each firm, upon being privately informed about ... -
Analysis of the Behavior of Transient Period in Non-Terminating Simulations
(Elsevier, 2006-08-16)Computer simulation is a widely used tool for analyzing many industrial and service systems. However, a major disadvantage of simulation is that the results are only estimates of the performance measures of interest, hence ... -
Stochastic lot sizing problem with controllable processing times
(Elsevier, 2015-06)In this study, we consider the stochastic capacitated lot sizing problem with controllable processing times where processing times can be reduced in return for extra compression cost. We assume that the compression cost ... -
Robust portfolio choice with CVaR and VaR under distribution and mean return ambiguity
(Springer, 2014-01-09)We consider the problem of optimal portfolio choice using the Conditional Value-at-Risk (CVaR) and Value-at-Risk (VaR) measures for a market consisting of n risky assets and a riskless asset and where short positions ... -
Quantifying the value of buyer-vendor coordination: Analytical and numerical results under different replenishment cost structures
(Elsevier, 2008-06-16)Despite a growing interest in channel coordination, no detailed analytical or numerical results measuring its impact on system performance have been reported in the literature. Hence, this paper aims to develop analytical ... -
The latest arrival hub location problem for cargo delivery systems with stopovers
(Elsevier, 2007-10)In this paper, we concentrate on the service structure of ground-transportation based cargo delivery companies. The transient times that arise from nonsimultaneous arrivals at hubs (typically spent for unloading, loading, ... -
Integration of shipment scheduling decisions for forward and reverse channels in a recoverable item system
(Elsevier, 2012-11)In this paper, we consider the problem of finding the economic shipment quantities of failed and recovered items between a central depot and a collection center to coordinate the flow in both ways. Our model takes an ...
