Accounting for Parameter Uncertainty in LargeScale Stochastic Simulations with Correlated Inputs
(Informs, 20110601)This paper considers largescale stochastic simulations with correlated inputs having normaltoanything (NORTA) distributions with arbitrary continuous marginal distributions. Examples of correlated inputs include ... 
Accurate Calculation of Hazardous Materials Transport Risks
(Elsevier, 200307)We propose two pathselection algorithms for the transport of hazardous materials. The algorithms can deal with link impedances that are pathdependent. This approach is superior to the use of a standard shortest path ... 
Adjusted Hazard Rate Estimator Based on a Known Censoring Probability
(Taylor & Francis, 201111)In most reliability studies involving censoring, one assumes that censoring probabilities are unknown. We derive a nonparametric estimator for the survival function when information regarding censoring frequency is ... 
Agebased vs. stock level control policies for a perishable inventory system
(Elsevier, 20011016)In this study, we investigate the impact of modified lotsizereorder control policy for perishables which bases replenishment decisions on both the inventory level and the remaining lifetimes of items in stock. We derive ... 
Aircraft rescheduling with cruise speed control
(INFORMS, 20140523)Airline operations are subject to frequent disruptions typically due to unexpected aircraft maintenance requirements and undesirable weather conditions. Recovery from a disruption often involves propagating delays in ... 
Allocation Strategies in Hub Networks
(Elsevier, 20110611)In this paper, we study allocation strategies and their effects on total routing costs in hub networks. Given a set of nodes with pairwise traffic demands, the phub median problem is the problem of choosing p nodes as hub ... 
Analysis and applications of replenishment problems under stepwise transportation costs and generalized wholesale prices
(Elsevier, 201211)In this study, we analyze the replenishment decision of a buyer with the objective of maximizing total expected profits. The buyer faces stepwise freight costs in inbound transportation and a hybrid wholesale price ... 
An analysis of cyclic scheduling problems in robot centered cells
(Elsevier, 201206)The focus of this study is a robot centered cell consisting of m computer numerical control (CNC) machines producing identical parts. Two pure cycles are singled out and further investigated as prominent cycles in ... 
Analysis of order review/release problems in production systems
(Elsevier, 19990920)Order Review/Release (ORR) activities have mostly been ignored in past job shop research. In most previous studies, arriving jobs are immediately released to the shop #oor without considering any information about the ... 
Analysis of reactive scheduling problems in a job shop environment
(Elsevier, 20001101)In this paper, we study the reactive scheduling problems in a stochastic manufacturing environment. Specifically, we test the several scheduling policies under machine breakdowns in a classical job shop system. In addition, ... 
Analysis of simple inventory control systems with execution errors: Economic impact under correction opportunities
(Elsevier, 201006)Motivated by recent empirical evidence, we study the economic impact of inventory record inaccuracies that arise due to execution errors. We model a set of probable events regarding the erroneous registering of sales at ... 
Analysis of the Behavior of Transient Period in NonTerminating Simulations
(Elsevier, 20060816)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 ... 
Ant colony optimization for the single model Utype assembly line balancing problem
(Elsevier, 200908)An assembly line is a production line in which units move continuously through a sequence of stations. The assembly line balancing problem is defined as the allocation of tasks to an ordered sequence of stations subject ... 
An anticipative scheduling approach with controllable processing times
(Elsevier, 201006)In practice, machine schedules are usually subject to disruptions which have to be repaired by reactive scheduling decisions. The most popular predictive approach in project management and machine scheduling literature is ... 
Asymptotically optimal Bayesian sequential change detection and identification rules
(Springer, 20130412)We study the joint problem of sequential change detection and multiple hypothesis testing. Suppose that the common distribution of a sequence of i.i.d. random variables changes suddenly at some unobservable time to one ... 
Averaging methods for transient regimes in overloading retrial queueing systems
(Elsevier, 199908)A new approach is suggested to study transient and stable regimes in overloading retrial queueing systems. This approach is based on limit theorems of averaging principle and diffusion approximation types for socalled ... 
Backtracking and exchange of information: Methods to enhance a beam search algorithm for assembly line scheduling
(Elsevier, 20080501)Beam search (BS) is used as a heuristic to solve various combinatorial optimization problems, ranging from scheduling to assembly line balancing. In this paper, we develop a backtracking and an exchangeofinformation (EOI) ... 
Bayesian demand updating in lost sales newsvendor: a two moment approximation
(Elsevier, 20071001)We consider Bayesian updating of demand in a lost sales newsvendor model with censored observations. In a lost sales environment, where the arrival process is not recorded, the exact demand is not observed if it exceeds ... 
The Best GainLoss Ratio is a Poor Performance Measure
(SIAM, 20130306)The gainloss ratio is known to enjoy very good properties from a normative point of view. As a confirmation, we show that the best market gainloss ratio in the presence of a random endowment is an acceptability index, ... 
Bicriteria robotic operation allocation in a flexible manufacturing cell
(Elsevier, 201004)Consider a manufacturing cell of two identical CNC machines and a material handling robot. Identical parts requesting the completion of a number of operations are to be produced in a cyclic scheduling environment through ...
