Cost-efficient Variable Selection Using Branching LARS

Yue, Li Hua - 2010

Variable selection is a difficult problem in statistical model building. Identification of cost efficient diagnostic factors is very important to health researchers, but most variable selection methods do not take into account the cost of collecting data for the predictors. The trade off between...

Sequential Search With Ordinal Ranks and Cardinal Values: An Infinite Discounted Secretary Problem

Palley, Asa Benjamin - 2009

We consider an extension of the classical secretary problem where a decision maker observes only the relative ranks of a sequence of up to N applicants, whose true values are i.i.d. U[0,1] random variables. Applicants arrive according to a homogeneous Poisson Process, and the decision maker...

The Economics of Nuclear Power

Horst, Ronald L - 2006

We extend economic analysis of the nuclear power industry by developing and employing three tools. They are 1) compilation and unification of operating and accounting data sets for plants and sites, 2) an abstract industry model with major economic agents and features, and 3) a model of nuclear...

Cut-first branch-and-price-second for the capacitated arc-routing problem

Bode, Claudia; Irnich, Stefan - 2011

This paper presents the first full-fledged branch-and-price (bap) algorithm for the capacitated arc-routing problem (CARP). Prior exact solution techniques either rely on cutting planes or the transformation of the CARP into a node-routing problem. The drawbacks are either models with inherent...

Cost Estimating Certifications Offered by Professional Societies in the United States and Abroad

Remer, Donald S.; Ahle, Karen; Alley, Kevin; Silny, John; … - 2007

Many projects in industry and government go over budget and schedule. In most engineering economics courses, the emphasis is on how to compare alternatives and learn about time value of money and interest and inflation rates. The students are usually given the costs and asked to compare the...

Resource allocation in the Grid. A market engineering approach

Schnizler, Björn - 2007

The Grid provides access to distributed computational capabilities such as processors or storage space. One of the key problems is deciding which jobs are to be allocated to which resources at what time. In this context, the use of market mechanisms is a promising approach to solve these...

Market-Based Scheduling in Distributed Computing Systems

Stößer, Jochen - 2009

In verteilten Rechensystemen (bspw. im Cluster und Grid Computing) kann eine Knappheit der zur Verfügung stehenden Ressourcen auftreten. Hier haben Marktmechanismen das Potenzial, Ressourcenbedarf und -angebot durch geeignete Anreizmechanismen zu koordinieren und somit die ökonomische...
