Symmetry in Scheduling Problems
The presence of symmetry is common in certain types of scheduling problems. Symmetry can occur when one is scheduling a collection of jobs on multiple identi...

This study proposes a game theoretic approach toward the analysis of renewable portfolio standard policy (RPS), which is one of the main forces behind prom...
BibTeX reference
The production-routing problem can be seen as a combination of two well known combinatorial optimization problems: the lotsizing and the vehicle routing prob...

The role of the Information and Communication Technology sector on productivity and economic growth is constantly increasing and, due to its pervasiveness, ...
BibTeX referencePositive Edge: A Pricing Criterion for the Identification of Non-Degenerate Simplex Pivots
The <i>positive edge</i> is a new pricing rule for the primal simplex: it identifies, with a probability error less than or equal to 2<sup>-30</sup> in sing...

The computational intractability of the dynamic programming (DP) equations associated with optimal admission and routing in stochastic loss networks of any n...
BibTeX reference
Paleoclimate evidence and climate models indicate that certain elements of the climate system may exhibit thresholds, with small changes in greenhouse gas em...
