We had a record (21 inch) snowfall on Friday night, if you consider the 4th biggest snowfall of all time (since the 1860s) a record. Since then, our city seems to be trying to turn this into our own little Katrina, showing very little planning or execution in getting the city back in working order. City schools are closed and our street has yet to see a plow. Once a car is painfully extracted from its snow cocoon, a curious Pittsburgh rite begins: the placement of the kitchen chair. Since the city is unable to actually remove any snow (it only pushes it around a bit), no on-street…

Make Amazon work Better
3 Feb 2010 | 2:51 pm… if you are qualified, that is. I don’t normally post job ads on the blog: there are other outlets for that. But I have a few reasons for posting this one: I have always been interested in the operations research issues that Amazon faces. How can they get so much stuff to me in one day? And when I order twice in one day, why don’t they combine the orders into one box? The person asking is Shivi Shankaran who is a Tepper School MBA alum, and I love pointing out to my MBA students how operations research skills are a real competitive advantage for them. Other… -
What Panels would you Like to See?
3 Feb 2010 | 6:32 amThe organizers at this Fall’s INFORMS Meeting (theme of the conference: “Willie, Lance, and Optimizing the Music Scene in Austin”) have asked me to organize a series of panel discussions (or other “not four papers, each of 22.5 minutes” form) on topics of interest. These panels should not be on technical topics but rather on issues of professional interest. What would make for a good panel? Here are a few possibilties: Blogging, Twitter, and Facebook: Role for Operations Researchers (of course!) Editors Panel: How to be a successful author, referee, and… -
AIMMS Contest
1 Feb 2010 | 11:18 amI can’t resist competitions in operations research. It brings out the competitor in me, even if it is more like ESPN and sports: I like to watch others doing the work! AIMMS (whose software I use in class) is sponsoring their second modeling competition, in conjunction with this year’s MOPTA (Modeling and Optimization: Theory and Applications) conference. Last year’s competition was on scheduling trucks subject to maintenance requirements. This year’s competition is on creating financial portfolios that embed tax issues: Classical models used in portfolio… -
Yo Trick! Where’ve you been?
25 Jan 2010 | 9:03 amI was annoyed at myself this morning when I realized that January was almost over and I had only 3 blog posts. Since my goal is 3/week, it is clear that I am getting the year off on the wrong foot. I could, of course, put in eight or so posts on being too busy to post (kinda like a tweet I had about being too busy to tweet!) but I don’t think my audience would fall for that: being OR people, they are pretty smart and can see through such an obvious ploy. But it has been an interesting month, so I thought I would update on some of things that are happening in my life. Perhaps…

Bachelor Efficiency.
6 Feb 2010 | 9:07 amIt seems to be a known fact that confirmed bachelors are at times amazing inventors of time and labor saving methods, gizmos, and procedures. Here is another one.Recently I was visiting my bachelor friend John at his house and when I was rummaging in his drawers, searching in vain for a spoon, he has proudly shown me his latest labor saving device, (which also explained the lack of spoons in the drawers). He didn’t claim the idea as his own, on contrary; he said it is becoming a trend among their bachelor brethren, but I have seen it for the first time.He has purchased himself two… -
Healthcare system improvement project management: making a big team work
31 Jan 2010 | 7:46 pmIt's tough chairing meetings, tougher chairing a big meeting (10-15 people), and tougher yet chairing a big meeting that's supposed to last an 8-hour day, one day a week for 6 months. A lot of planning goes into making such a day work with team members varying from the analytical kind to the "feeling" kind, from the surgical kind to the managerial kind. I'm slowly to get a hang of it having done it for a couple months now. The following is a lot of common sense, but if one doesn't have the chance to go through this kind of work with big teams, one may not think it so obvious as an approach. -
CORU Clinical Operational Research Unit - London health care OR team
29 Jan 2010 | 2:31 amCORU - Clinical Operational Research Unit, based in UCL (University College of London), is a London health care OR team - the first I've come across working in OR specialising in health care, since I moved across the pond last year from Canada.Needless to say, I was very happy to meet up with Martin Utley, Director of CORU, last week. Thanks for a great chat, Martin. I'm genuinely excited to link up with the CORU group, as I have not yet met any OR bodies in health in UK yet. Reading up on some publications that Martin sent over - I do miss the academic side of Operational Research. It was… -
Psychotherapy and Operational Research / Change Management

"Although there are many details about our patients that we cannot know, nonetheless, our task is to delimit a system of observation in which we can trace the essential causal chains, and find accessible points, or handles, where interventions can be made."2.

Healthcare system improvement project management: how not to manage projects
6 Nov 2009 | 12:45 amLately, I am finding it difficult to not do the work myself in the projects I'm leading/managing. The excuse I've been using is "well, it's just easier to do it myself than asking someone else for it". However, I end up paying for it with way too many late nights working around the clock. I'll be the first to admit: this is the wrong way to manage projects. I end up feeling burned out and tired doing work that should have been done by others in the team, leaving me without enough energy or time to actually 'manage' the projects. Ultimately, if I continued this way, it would be both bad for me…

do not text and drive
8 Feb 2010 | 12:33 pmDespite what you might have read in the news lately, a recent OR paper suggests that you should not use your cell phone while driving. Alex Nikolaev, Matthew Robbins, and Sheldon Jacobson recently wrote a paper that analyzed traffic accidents in 62 counties in New York before and after a cell-phone-while-driving ban. The University of Illinois press release summarizes their results: The team found that after banning hand-held cell phone use while driving, 46 counties in New York experienced lower fatal accident rates, 10 of which did so at a statistically significant level, while all 62… -
OR and the Superbowl?
8 Feb 2010 | 7:22 amI hope you enjoyed the game last night. How was OR used for the Superbowl? I enjoyed reading about the logistics of the 2005 Superbowl in Jacksonville, Florida–including using cruise ships to provide enough hotel rooms–but I didn’t see anything similar for yesterday’s game. Please share anything you’ve found. Are the commercials worth the price tag now that viewers watch their favorites online? What was your favorite commercial? Tagged: sports -
The numbers behind health care – for a lay audience
31 Jan 2010 | 1:09 pmIn October, This American Life produced two interesting episodes about health interventions and evidence-based medicine that I am just listening to now. These This American Life shows seem fresh and interesting, largely because they try to discuss health insurance/care issues from a quantitative, evidence-based perspective, even though cite few numbers in the episodes. To illustrate this point, part of the first episode is even titled “Every CAT scan has nine lives,” referring to the side effects of over-using advanced medical techniques such as CAT scans. The More is Less… -
a combinatorial coupon challenge
25 Jan 2010 | 6:36 amNormally I do not get that excited about grocery shopping, but this Sunday was an exception: I used OR to do my grocery shopping. Many grocery stores have promotions that encourage shoppers to buy 10 items, such as the 10 for $10 sales. Oddly, there has typically been no penalty for buying fewer than ten items: all items would be $1 each. The sale merely suggests to stock up on ten or more sale items. This past year, my favorite grocery store (Kroger) has periodically offered a promotion that offers $5 cash back for every ten items purchased (but not any ten items, just the items… -
do women read this blog?
20 Jan 2010 | 10:53 amI was fascinated by a post about science news and gender that I read this week on the Eureka Zone, a Times Online science blog. Science research councils have increasingly encouraged their grant-holders to engage with the public about their work and for many research grants some form of public engagement is now a necessity. But whom do these scientists end up engaging? They find–for reasons unexplained in the article–that men disproportionally read science news. [M]en are more likely to actively choose to consume science in their free time and the bias is much greater than that…

The game theoretic advantage goes to the Republicans
8 Feb 2010 | 6:29 amPundits have asked themselves why it is so difficult for the Democrats to get things done even with 60 votes in the Senate, whereas the Republicans seem to do just fine with 50 votes in the Senate. I suspect that there are a number of reasons for this. But one reason that deserves mentioning is that Democrats believe in the importance of the federal government, and Republicans believe in the importance of thwarting Democrats. Consider the following table, which illustrates the values to Democrats and Republicans when the Democrats are in majorities in Congress. When Democrats control… -
Random thoughts on the Massachusetts election
20 Jan 2010 | 7:26 amYesterday, Scott Brown (a Republican) defeated a Martha Coakley (a Democrat) for the Senate seat in Massachusetts. The Senate seat was generally known as Ted Kennedy’s Senate seat because Kennedy was the Massachusetts Senator since 1962. I have a number of thoughts on the election. Here they are, in somewhat random order. The election of Scott Brown will kill the health reform bill because it will give Republicans 41 Senate seats, enough to filibuster any bill. Most Americans will be grateful, with notable exceptions including those who can’t afford health insurance, those… -
The Senate is broken!
7 Jan 2010 | 2:09 pmUS Citizens strongly believe in the United States Constitution and support it wholeheartedly. This is somewhat paradoxical since most Americans cannot name the three branches of government (on the brighter side, 3/4 can name the three Stooges I could go on about how little Americans know about the Constitution, but I really want to address a different point. The U.S. Senate is broken. Paul Krugman articulated this point well, and I fully agree. Here are three ways that it is broken: Because of the incredible overuse of “filibusters”, Democrats need 60 senators to get any bill… -
On the Failed Airplane Bombing Attempt
31 Dec 2009 | 6:48 amWhen geese “attacked” US Air Flight 1549, and Captain Sully Sullenberger landed the plane in the Hudson river, Americans were overjoyed that disaster had been averted. When Abdul Mudallah ignited an explosive device on Northwest Flight 253, and no one was injured, Americans spent the next week afraid, with countless criticisms of our government (many of which were justified). In reality, we should all be very thankful. First of all, we should be thankful that disaster was averted. This was great news. We should also be thankful because we have learned a great deal of what went… -
Traveling Incognito
18 Dec 2009 | 9:45 amSarah Palin, in a recent vacation trip to Hawaii, wore a “McCain for President” visor, but crossed out the words. Her explanation was: ”I Sharpied the logo out on my sun visor so photographers would be less likely to recognize me”. So, if I understand correctly, she thinks that photographers recognize her by her logo instead of the way she looks. Or perhaps she thought that crossing out the logo would make her invisible. In any case, despite all these strenuous efforts at traveling incognito, she was recognized. Who could have guessed that photographers…

C-ROADS Climate Model
5 Jan 2010 | 8:53 pmMIT system dynamicist John Sterman, who gave a plenary on climate policy modeling at INFORMS 2009, now has a podcast about that topic on the INFORMS Science of Better site. A good deal of the podcast serves as general background on climate change projections, international accords, and the concept of cap and trade. Sterman and his colleagues developed a climate policy model called C-ROADS, available from the website climateinteractive.org. C-ROADS models the impacts of policies (such as ones discussed at the recent Copenhagen meetings) on climate change. The base case of the model uses the… -

The Lean Recession
21 Jan 2010 | 4:28 amThe WSJ just posted (1/20/10) a small article about the semiconductor industry. Here is a line from the article: Distributors controlled 36.9 days of inventory at the end of the third quarter, down 15% from a year earlier,according to iSuppli. In dollar terms, distributors held $4.8 billion worth of semiconductor inventory at the end of the third quarter, down 22%. I couldn’t help but pull out Little’s Law to calculate the sales rate this year and last year. This year’s sales rate is R = I / T = 4.8 / (36.9 / 365) = 47.5$b. This year’s days-of-supply is down 15%… -
Will Intel keep rolling?
15 Jan 2010 | 4:40 amIntel is on a roll. They just reported 2009 Q4 revenue of $10.6 billion with net income of $2.3 billion – not bad indeed! (See NY Times, 1/14/20). The success is attributed to their recent investment in new plants ($7 billion), a resurgence in PC demand, and their move to make chips for netbook and smartphones (their Atom chip targeted to those markets brought in $1.4 billion in revenue). Kudos to Intel, but will the fun last? How long can Intel succeed with its strategy to heavily invest in new manufacturing technology so that it can stay ahead of rivals? There are reasons to… -

Death to Facebook – a self service nightmare
13 Jan 2010 | 5:11 amBefore getting to Facebook, let’s start off with Google. The NY Times today reported on Google’s troubles with their customer service for their new phone, the Nexus One (see NY Times 1/12/10). Apparently, if you have a problem with the phone, there is no one to call – no customer service representative to help you figure out why you can’t use your phone … nobody! This should not come as a surprise to those of us (all of us?) who use Google’s search page – nobody to call if you have problems with that either. But the big difference is that who… -
Ford to build one Focus
9 Jan 2010 | 8:07 pmFord is trying to do it again. Do you remember the Escort? It was suppose to be the “world car”, but apparently there was only about one part that was common between the U.S. and the European versions. But that was then and this is now. Ford is (and they are serious this time) committed to developing *one* Focus for the world (see NY Times, 1/9/2010) The strategy is based on the premise that preferences are converging around the world and so the one world car strategy is feasible. Not only is this probably correct, it probably has been correct for quite some time –…

Braess paradox, queuing (standing in line), and the Boston Globe
6 Feb 2010 | 2:27 pmI was pleased to see James Parker's column in the Boston Globe on queuing, which he says is what separates man from beasts. He gives credit to anthropologists for noting that queuing represents stable cooperative equilibrium and then goes out to note the Braess paradox, due to Professor Dietrich Braess, which showed that the addition of a new road may make everyone worse off in terms of travel time in the network. However, in the column he misrepresents the Braess paradox by saying that it reflects that two lines are shorter than a single line or queue. In the Braess paradox, the addition of… -

2 Feb 2010 | 4:33 pmThe New York Times has a very interesting, provocative article on the pooling of resources for humanitarian operations and, in particular, as applied to Haiti, but the topic is broader and relevant in other disaster and humanitarian relief contexts. The article is focused on the pooling of financial resources and notes that the Red Cross, although it did not have a large presence in Haiti prior to the earthquake, because of its brand name recognition, has received many more financial donations than has Partners in Health, which has had a large presence in Haiti, even before the earthquake…

Risky Business
31 Jan 2010 | 8:13 amNo, this is not yet another review of Tom Cruise’s breakthrough movie. It is about how decision makers in governments and business make their decisions, especially when the dynamics of the challenge they are facing is misunderstood. Understanding the dynamics of a system requires mastery of concepts like stocks, flows, delays, nonlinearities, feedback loops and uncertainty. Lack of understanding these concepts causes decision makers to make the wrong decisions. With the use of simple and easy to grasp models an analytical consultant can help government and business to make better decisions… -
Mexican flu vaccine campaign; a false positive?
30 Dec 2009 | 8:29 amGreat news this week, the Mexican flu epidemic is officially over in the Netherlands. In July of this year, the first cases of Mexican flu were reported. At that time the World Health Organisation (WHO) already had signalled that the danger of a flu pandemic was growing and every country was advised to take appropriate counter measures. One in every 3 persons would get infected if no counter measures were taken. In the Netherlands this lead to the “Grip op Griep” campaign informing people on how to reduce the chances of getting infected. With silly posters people were told how to sneeze… -

Go GREEN!
25 Oct 2009 | 8:23 amLast week I had a presentation at the ORTEC user conference, together with one of my friends form the Antwerp University, Patrick Schittekat. Also Walther Ploos van Amstel was there with a nice speech on the diminishing elasticity in logistics. Our subject was on how to be green from an environmental perspective but still be competitive. We state that instead of waiting for the governments to come up with measures to reduce emissions, companies should re-think their supply chain now. That way companies can turn going green from a liability into an asset and are well prepared for the future. -

A quantative based risk assessment would have lead to better estimation of the financial risks upfront and better risk mitigation strategies during the project.At the start of the project the total investment for the metro line was estimated to be €430 million. Based on this estimation the Amsterdam council decided to go ahead with the plan. Besides the relief the metro would bring to the dense traffic in the centre of the city, making it more healthier to…

What follows, then, is the post as I wrote it the other day: I am of the opinion it takes a certain kind of sensibility to understand how and why Enterprise 2.0 fits into an organization and, more importantly, how it can increase the effectiveness of everyone and everything with respect to how that organization realizes its goals.
