Practice Prize Competition


Each year the Canadian Operational Research Society conducts a competition on the practice of operational research to recognize the challenging application of the OR approach to the solution of applied problems. The main criteria considered in evaluating submissions are project impact on the client organization, contribution to the practice of O.R., quality of analysis, degree of challenge and quality of written and oral presentation.

There are two basic purposes behind the Competition, the first being the obvious one of recognizing outstanding O.R. practice. The other is to focus attention on O.R. and its applications by practitioners from Canada by attracting quality papers to the CORS National Conference.

3D container loading project wins first prize of the 2017 CORS Practice Prize competition

The first Prize was awarded to Philippe Grangier, Marc Brisson, Michel Gendreau, Fabien Lehuédé, Louis-Martin Rousseau and John Ye for their project entitled “A two phase algorithm for a real life 3D container loading problem”. The assessment of the committee was “The project tackles a challenging problem, has a demonstrated impact in the client organisation, uses an innovative combination of solution methods and is used in a production system”.

The second Prize is awarded to Felipe Rodrigues, David Stanford and Greg Zaric for the project entitled “Discrete event simulation model for planning level 2 “step-down” bed needs using NEMS”. The assessment of the committee was “The prize committee greatly appreciated how the project study challenges a conservative organisation in a complex system”.

The prizes were awarded during CORS/IFORS 2017. The members of the Prize committee were Mikael Rönnqvist (chair), Bernard Gendron, Fredrik Odegaard and Mustapha Ouhimmou.
