Proud of my Masters Program in OR Winning the George D Smith Prize

This year's INFORMS Business Analytics and Operations Research conference was held in Huntington Beach, California. Excellent talks on really relevant topics. Great conference, networking and top organizers. :)

Best of all, my former masters program in Operations Research, the Centre for Operations Excellence at the Sauder School of Business, University of British Columbia, won this year's George D Smith Prize. This is the field's top prize recognizing some of the best education programs.
The UPS George D. Smith Prize is awarded to an academic department or program for effective and innovative preparation of students to be good practitioners of operations research.

I was honoured to be at the gala event, and ecstatic for the program's win. My career would not have looked quite the same without the program. So happy for them.

Similarity between “A Single EU Sky” and “Ford Suppliers”? Optimization

How should EUROCONTROL select which improvement projects to invest in for a unified European sky for air traffic by the year 2020? Will Ford’s Automative Holding Components shut down their facilities and outsource everything? Optimization models come to the rescue, and they are big! 2 of the 6 finalists for the Daniel H. Wagner Prize for Excellence in Operations Research presented their exciting projects at INFORMS on Monday.

The air traffic is getting more and more congested in Europe, and a solution is needed to unite the European sky with a single set of protocols for all EU countries. EUROCONTROL is in the position to do so. It is the European Organization for the Safety of Air Navigation, and it currently has 37 member states. As a part of the modernization activities, EUROCONTROL needs to select a set of technological improvement projects from four major categories: network efficiency, airport operations, sector productivity, and safety net. For example, if considering only a subset of 5 projects out of a list of 20+ projects, each with 2 to 5 implementation options, there would be 300 possible combinations. Therefore, the question is which set of projects to select that would satisfy the various objectives and constraints of multiple stakeholders, such as the airports, the airlines, the society (environment), and more. Grushka’s team from the London Business School was asked by EUROCONTROL to provide vigorous and transparent analysis of this problem by involving all stakeholders. The team used an integrative and iterative framework to approach the problem. They used a mixed integer programming model to find the optimal combination of projects. As a result of this team’s effort, the EU may now use the same language to talk about uniting the European sky with a common understanding of the problem.

The Ford team had a very different but extremely urgent problem to solve. They needed to figure out whether 2 of their automotive interior supply production facilities should be closed down and their work outsourced to other suppliers because of unprofitability and underutilization at the plants. The number one problem was time – 8 weeks was all they had. The optimization problem they faced, however, was extremely large. The mixed integer non-linear programming model (MINLP) had around 450,000 variables and 200,000 constraints. After removing nonlinearity in the model, the mixed integer programming model (MIP) had 4.3 million variables and 1.8 million constraints. Just imagine the data gathering process and the model formulation! What a nightmare. Luckily, the team had the unconditional support from the CEO and was able to obtain a complete set of data –150,000 data points in the model. After 8 weeks of 20 hour-days, the team was able to deliver a model to test out the what-if scenarios and therefore removing the subjective decision making that is so common in most enterprises. As a result, Ford will be able to maintain 1 facility and outsource only a certain percentage of the work. It presented a saving of $50 million over five years compared to the alternative of outsourcing all the work.

The two projects were fascinating to listen to. They both showcased the importance of quantitative decision making in business. It will be a tough job to select a winner out of these two. Good luck to both teams!

Edelman Award: The Oscar of O.R.

The 2008 Edelman award winner is...(drum roll please...)

The Netherlands Railways!
Traffic on the railway nearly doubled between 1970 and 2006, but its timetable had not changed, leading to commuting problems...

Restructuring increased the percentage of trains arriving within three minutes of schedule from 84.8 percent in 2006 to 87 percent in 2007, while the number of passengers increased 2 percent in the first six months of 2007.

Profit, meanwhile, rose $60 million and the changes made additional capacity available...
Read more about it here. Or watch the YouTube reward ceremony here - pretty dramatic stage, eh! That's why it's the Oscar of Operations Research. :)
