Truckload freight transportation utilizing relay points to improve the driving job
(2012-07)
We propose a relay point based approach on a highway transportation network to obtain robust solutions for the truck driver turnover and driver retention problem. We exploit the characteristics of the driver routing problem ...
Comparing the performance of ordinal logistic regression and artificial neural network when analyzing ordinal data
(2012-07)
Scope and Method of Study: The purpose of this study is to compare the performance of the Ordinal Logistic Regression (OLR) and Artificial Neural Network (ANN) models when analyzing ordinal data using different scenarios ...
Supply chain coordination under sales effort free riding
(2012-07)
We study a supply chain with one manufacturer and two retail channels, where an online retailer offers a lower price and free-rides a brick-and-mortar retailer's sales effort. The free riding effect reduces brick-and-mortar ...
Polyhedral combinatorics, complexity and algorithms for k-clubs in graphs
(2012-07)
A k-club is a distance-based graph-theoretic generalization of clique, originally introduced to model cohesive subgroups in social network analysis. The k-clubs represent low diameter clusters in graphs and are suitable ...
Modeling inventory information visibility in supply chain networks
(2012-05)
Scope and Methods: The stock-out rate at a store has become a serious concern for firms in a supply chain network (SCN). This situation can lead to loss in customer good will and market share. Information sharing among the ...
