Student Paper Competition

Description

Each year the Canadian Operational Research Society conducts a student paper competition to recognize the contribution of a paper either directly to the field of operational research through the development of methodology or to another field through the application of operational research. The competition serves to showcase the high quality of OR education in Canada as well as the excellence of the new generation of operational researchers. Prizes are awarded in two categories: Undergraduate and Open.

First Prize - Open Category

"A Markov Chain Model for the Performance of an EMS System with Repositioning"
Ramon Alanis, School of Business, University of Alberta

We propose and analyze a two-dimensional Markov chain model to analyze an Emergency Medical System (EMS) that repositions ambulances using a compliance table policy, which is commonly used in practice. The model is solved via a fixed-point iteration. We validate the model against a detailed simulation model. We demonstrate that the model provides accurate approximations to the response time distribution and the distribution of the number of busy ambulances and that it can be used to identify near-optimal compliance tables.

"Community Facility Services: Drive Time and Market Share Analysis"
Erin Hrycyschyn, Felicia Ng, Brent Ouwerkerk, Jimmie Tom, Sean Tomilin, University of Alberta

Our Client has been collecting data for many years, however, there has been no initial analysis on any of the information that they have collected thus far. We have been commissioned to take the first steps at analyzing this data to draw awareness as to the gravity of their facilities on the general population to improve the coordination of maintenance shutdowns. We have used a GIS interface to model a drive time analysis of their facilities and have consolidated this analysis with an operating hour analysis to gain insight into their early hour customer behaviour. Similarly we combined the drive time analysis with facility closure information to predict migration patterns when facilities close for maintenance.
