Identification and elimination of interior points for the minimum enclosing ball problem
(Society for Industrial and Applied Mathematics, 2008)Given A := {a1,...,am} C ℝn, we consider the problem of reducing the input set for the computation of the minimum enclosing ball of A. In this note, given an approximate solution to the minimum enclosing ball problem, we ... -
The impact of abusing return policies: a newsvendor model with opportunistic consumers
(Elsevier, 2018)Consumers may return a product for a variety of reasons, such as the product having the wrong color or size, having poor functionality, being damaged during shipment, or simply prompting regret for an impulsive purchase. ... -
The impact of frying aerosol on human brain activity
(Elsevier, 2019)Knowledge on the impact of the exposure to indoor ultrafine particles (UFPs) on the human brain is restricted. Twelve non-atopic, non-smoking, and healthy adults (10 female and 7 male, in average 22 years old) were monitored ... -
The impact of price skimming on supply and exit decisions
(John Wiley & Sons, 2015)Stochastic inventory control theory has focused on the order and/or pricing policy when the length of the selling period is known. In contrast to this focus, we examine the optimal length of the selling period - which we ... -
Impacts of battery characteristics, driver preferences and road network features on travel costs of a plug-in hybrid electric vehicle (PHEV) for long-distance trips
(Elsevier, 2014-11)In a road network with refueling and fast charging stations, the minimum-cost driving path of a plug-in hybrid electric vehicle (PHEV) depends on factors such as location and availability of refueling/fast charging stations, ... -
Implementation of warm-start strategies in interior-point methods for linear programming in fixed dimension
(Springer, 2008)We implement several warm-start strategies in interior-point methods for linear programming (LP). We study the situation in which both the original LP instance and the perturbed one have exactly the same dimensions. We ... -
An improved probability bound for the Approximate S-Lemma
(Elsevier, 2007)The purpose of this note is to give a probability bound on symmetric matrices to improve an error bound in the Approximate S-Lemma used in establishing levels of conservatism results for approximate robust counterparts. -
Incorporating just-in-time into a decision support system environment
(Elsevier BV, 1991)In this paper, a Decision Support System is proposed for a Just-In-Time production system. The Decision Support System includes three components: database, model base, and interface. The database contains the predefined ... -
Incremental polynomial time dualization of quadratic functions and a subclass of degree-k functions
(Springer, 2011-08)We consider the problem of dualizing a Boolean function f represented by a DNF. In its most general form, this problem is commonly believed not to be solvable by a quasi-polynomial total time algorithm.We show that if ... -
Inequity averse optimization in operational research
(Elsevier, 2015)There are many applications across a broad range of business problem domains in which equity is a concern and many well-known operational research (OR) problems such as knapsack, scheduling or assignment problems have been ... -
Influence of diamond tool chamfer angle on surface integrity in ultra-precision turning of singe crystal silicon
(Springer, 2019)Ultra precision diamond machining enables the economical production of freeform optics on infrared materials such as silicon. To produce optics with acceptable surface integrity, it is important to have a good understanding ... -
Influence of tool wear on machining forces and tool deflections during micro milling
(Springer, 2016)Tool wear on the cutting edges of micro end mills is an important issue affecting process outputs such as tool deflections and surface roughness, especially when difficult-to-cut materials such as titanium alloys, stainless ... -
Information and preference reversals in lotteries
(Elsevier, 2011)Several approaches have been proposed for evaluating information in expected utility theory. Among the most popular approaches are the expected utility increase, the selling price and the buying price. While the expected ... -
Input data analysis using neural networks
(Sage Publications, 2000)Simulation deals with real-life phenomena by constructing representative models of a system being questioned. Input data provide a driving force for such models. The requirement for identifying the underlying distributions ... -
An Input/Output control system for the dynamic job shop
(Taylor & Francis, 1987)A combined input/output control system is presented for periodically determining the set of jobs to be released (input variables) and the capacities of processing centers (output variables) in the dynamic job shop, so that ... -
The integer knapsack cover polyhedron
(Society for Industrial and Applied Mathematics, 2007)We study the integer knapsack cover polyhedron which is the convex hull of the set of vectors x ∈ ℤ+ n that satisfy C T x ≥ b, with C ∈ ℤ++ n and 6 ∈ ℤ++. We present some general results about the nontrivial facet-defining ... -
An integer programming model for pricing American contingent claims under transaction costs
(2012)We study the problem of computing the lower hedging price of an American contingent claim in a finite-state discrete-time market setting under proportional transaction costs. We derive a new mixed-integer linear programming ... -
Integrated aircraft and passenger recovery with cruise time controllability
(Springer, 2016)Disruptions in airline operations can result in infeasibilities in aircraft and passenger schedules. Airlines typically recover aircraft schedules and disruptions in passenger itineraries sequentially. However, passengers ... -
Integrated aircraft-path assignment and robust schedule design with cruise speed control
(Elsevier, 2017-08)Assignment of aircraft types, each having different seat capacity, operational expenses and availabilities, critically affects airlines’ overall cost. In this paper, we assign fleet types to paths by considering not ... -
An integrated approach for airline scheduling, aircraft fleeting and routing with cruise speed control
(Elsevier, 2016)To place an emphasis on profound relations among airline schedule planning problems and to mitigate the effect of unexpected delays, we integrate schedule design, fleet assignment and aircraft routing problems within a ...
