Where are we heading?

by Marco Lubbecke

In a recent blog post, I asked the question where our field is heading. Our field, that is operations research, and I was asking for the next big research questions. My conclusion was that we should all work hard to establish operations research as the science behind “very popular notions” like big data, internet of things, industry 4.0, etc., before these are captured by non-scientists. It may sound like a purely academic endeavour but I believe that practice will hugely benefit from this in the end.

So, where are we heading? That much is sure: to San Francisco next week. I will post updates here, in my blog, and on twitter using #informs2014. Looking forward to meeting many of you there!

“good enough”

by Patrick Leach

My favorite phrase in the previous post is “…good enough in the context of our application.”  I continue to be amazed at the number of people who treat practical, real-life problems as though they were academic research problems – i.e., they want to find THE answer, rather than simply learning enough to make a confident decision.  Warren Buffet has been quoted as saying that he doesn’t care about what the exact results of an analysis are; in fact, if you have to know the exact result in order to be sure you’re making the right decision, you’re probably too close to a “decision boundary.”  Once Mr. Buffet is confident that he’s far enough away from such boundaries, he makes the decision and doesn’t look back.

Not Particularly Hard

by Shiva

While working on a new retail optimization problem a few weeks earlier, a colleague was a bit disappointed that it turned out to be NP-Hard. Does that make it unsolvable? No. The celebrated Traveling Salesman Problem (TSP) is known to be a difficult problem, yet Operations Researchers continue to solve incredibly large TSP instances to proven near-global optimality, and we routinely manage small TSP instances every time we lace our shoes. Why did I bring up laces? In a moment …

Hundreds of problems that are known to be difficult are ‘solved’ routinely in industrial applications. In this practical context it matters relatively less what the theoretical worst-case result is, as long as the real-life instances that show up can be managed well enough, and invariably, the answer to this latter question is a resounding YES. The worst-case exponential ‘Simplex method’ continues to be a core algorithm in modern-day optimization software packages.

This issue of contextual optimization is not a new one. For some ancient people who first came across ‘irrational’ numbers, it was apparently a moment of uneasiness: how to ‘exactly’ measure quantities that were seemingly beyond rational thought. For some others, it was not much of an issue. Indeed, there is an entire body of Ganitha (the science of calculations, or mathematics) work in Sanskrit, the ‘Sulba Sutras‘, almost 3000 years old, where irrational numbers show up without much ado. ‘Sulba’ means rope or lace or cord. If we want to calculate the circumference of a circle of radius r, we can simply use (2πr) along with an approximation for ‘π’ that is optimally accurate, i.e., good enough in the context of our application. If we we did not have a good enough value for π, we could literally get around the problem: simply draw a circle of radius r, and line up a Sulba along its circumference to get our answer. For really large circles, we can use a scaled model instead of ordering many miles of Sulba. Not particularly hard. The discovery of a new NP-Hard problem can be a positive thing, depending on how we respond to it. This could well be an ORMS motto:

“When the going gets NP-Hard, Operations Researchers get going”.

And this November, many of the world’s Operations Researchers are going west, to San Francisco. Welcome to the INFORMS annual conference!

What you need to know before you go…

by admin

We are looking forward to your participation at the 2014 INFORMS Annual Meeting in a few days in San Francisco, California.  Thanks to you this will be the largest and best meeting yet!  With record attendance, it is important to build in time to register and navigate the facility and arrive at desired sessions early to get a good seat.  We do expect many sessions to be standing room only so plan accordingly.

A fast and inexpensive way to get from the airport to the conference hotels is the Bay Area Rapid Transit, or BART. Trains arrive at the airport every 15 minutes and it is just a 30 minute ride to the downtown area. The closet BART station to the conference hotels is on Powell Street, a 5 minute walk away. Find more information about BART here: http://www.bart.gov/guide/airport/inbound_sfo

Taxi fares are approximately $41 each way. The airport shuttle is $15 each way and reservations must be made in advance. Make reservations at the discounted rate here: http://www.airportexpresssf.com/.
