A Branch-and-Price Algorithm for Parallel Machine Scheduling Using ZDDs and Generic Branching [PDF]

INFORMS Journal on Computing, 2016
We study the parallel machine scheduling problem to minimize the sum of the weighted completion times of the jobs to be scheduled (problem Pm∥∑wj Cj in the standard three-field notation). We use the set covering formulation that was introduced by van den Akker et al.

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

A branch‐and‐price algorithm for a targeting problem [PDF]

Naval Research Logistics (NRL), 2007
AbstractIn this paper, we consider a new weapon‐target allocation problem with the objective of minimizing the overall firing cost. The problem is formulated as a nonlinear integer programming model, but it can be transformed into a linear integer programming model.
