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...

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...

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...
