    I just attended a great talk by Laura McLay at the German OR Society meeting in Aachen.  In her semi-plenary, Laura talked about all the work she has done in Emergency Medical Response.  Planning the location and operation of ambulances, fire trucks, emergency medical technicians, and so on is a difficult problem, and Laura has made very good progress in putting operations research to use in making systems work better.  She has been recognized for this work not only in our field (through things like outstanding paper awards and an NSF CAREER award) but also by those directly involved in…

    Here are a few links for your weekend reading. Wealthy Los Angeles K12 school vaccination rates are as low as Sudan’s. We have a paradox: higher overall vaccination rates and higher vulnerability due to risk caused by social networks choosing not to vaccinate. A few OR/Stat bloggers have written about FiveThirtyEight and data journalism recently. I like Michael Lopez’s (@StatsByLopez) blog post on where FiveThirtyEight stands after six months and Nathan Brixius’s take on FiveThirtyEight’s burrito challenge. The sad, gradual decline of the fade-out in popular music.

    How do you recycle an entire stroller?  Here I describe how I went about it, inspired by concepts in The Upcycle and Cradle to Cradle.  We had been storing some old strollers and car seats we no longer used in a shed in our yard.  Some were slightly broken.  The shed roof had been leaking and so some of the items were further damaged.  In the process of fixing the shed, the time came to get rid of the strollers.  The water damage had resulted in mold on the stroller fabric.  So the strollers could not be readily reused by another family. I looked into recycling programs in my city and…

    The number of disasters is growing as well as the number of people affected by them from the Ebola epidemic in western Africa to the floods in Kashmir to humanitarian crises in war-torn Syria, Iraq, and eastern Ukraine. The challenges faced by citizens, humanitarian organizations, governments, and even businesses in dealing with disasters are immense and the research questions have never been more timely.Together, with Professors Panos M. Pardalos and Ilias Kotsireas, we are organizing a conference that will take place in Greece this summer that should not be missed.The conference is on…

  • Taking Optimization With You After Graduation

    Michael Trick
    7 Aug 2014 | 9:06 am
    In the Tepper MBA program, we use versions of Excel’s Solver (actually a souped up version from Frontline Systems)  for most of our basic optimization courses.  Students like this since they feel comfortable with the Excel interface and they know that they can use something like this in their summer internships and first jobs, albeit they are likely to the more crippled version standard with Excel.  For those who are particularly keen, we point them to an open source optimization system that can allow them to stay within the Excel structure. In our most advanced course, we use AIMMS…

    At the recent International Federation of Operational Research Society (IFORS) meeting in Barcelona (a fabulous conference, by the way), I had the honor of being nominated as President of that “society of societies”.  If elected, my term will start January 1, 2016, so I get a bit of a head start in planning. I was looking through one of the IFORS publications, International Abstracts in Operations Research.  I am sure I will write about this more, since I think this is a very nice publication looking for its purpose in the age of Google.  This journal publishes the abstracts…

    This year, I have the distinct honor of chairing the committee to award the Franz Edelman Award, given out by INFORMS for the best work that “attests to the contributions of operations research and analytics in both the profit and non-profit sectors”.  This competition has been incredibly inspiring to me throughout my career.  Just this year, as a judge, I got to see extremely high-quality presentations on eradicating polio throughout the world, bringing high-speed internet to all of Australia, facilitating long kidney exchange chains, and more.  I have seen dozens of…
  • Blogging and the Changing World of Education

    4 May 2014 | 9:02 am
    As a blogger, I have been a failure in the last six months.  I barely have enough time to tweet, let alone sit down for these extensively researched, tightly edited, and deeply insightful missives that characterize my blog.  I tell you, 1005 words on finding love through optimization doesn’t just happen! I have my excuses, of course.  As the fabulous PHD Comics points out, most of us academics seem somewhat overbooked, despite the freedom to set much of our schedule.  I am not alone in being congenitally unable to turn down “opportunities” when they come by.

  • Major League Baseball scheduling at the German OR Society Conference

    Laura McLay
    3 Sep 2014 | 4:39 am
    Mike Trick talked about his experience setting the Major League Baseball (MLB) schedule at the 2014 German OR Conference in Aachen, Germany. Mike’s plenary talk had two major themes: 1. Getting the job with the MLB 2. Keeping the job with the MLB The getting the job section summarized advances in computing power and integer programming solvers that have made solving large-scale integer programming (IP) models a reality. Mike talked about how he used to generate cuts for his models, but now the solvers (like CPLEX or Gurobi) add a lot of the cuts automatically as part of pre-processing.
  • WORMS Childcare Travel Fund application for the INFORMS Annual Meeting

    Laura McLay
    29 Aug 2014 | 8:32 am
    I am the Past-President of the Forum for Women in OR/MS (WORMS). My last initiative as President was to get the ball rolling on a travel fund for students and junior faculty traveling to the INFORMS Annual Meeting with babies and young children (Fact: I did this once!). The travel fund would help pay for childcare costs at the conference. A student member made the suggestion at the business meeting as a way to support (both literally and figuratively) young women in our field, and I thought it was something we should already have been doing. Current WORMS President Susan Martonosi (at…
  • academic blogs: a labor of love

    I recently discovered an articles about academics who blog from Tim Hitchcock (a humanities professor). The title really caught my eye: “Twitter and blogs are not add-ons to academic research, but a simple reflection of the passion that underpins it.” Yes! We don’t have to create and maintain blogs, we do so because we love our disciplines and we love to share our passion: The best (and most successful) academics are the ones who are so caught up in the importance of their work, so caught up with their simple passion for a subject, that they publicise it with every…
  • the 30 most important seconds of your thesis defense

    14 Aug 2014 | 6:18 am
    I’m on a lot of dissertation committees. While most of the committees are for students in my department, many are not in my area of operations research. I’m surprised at how hard it can be to follow along to the bigger picture and/or to the technical details. Even when I completely understand the technical details, I usually do not know enough about the specific research niche to characterize the dissertation’s contribution or novelty. I tell students that the most important part of their thesis or dissertation defenses are the 30 seconds when they summarize the key…

  • The Upcycle

    I recently finished reading The Upcycle by William McDonough and Michael Braungart.  It is the follow-up to their inspiring 2002 book Cradle to Cradle, which I wrote about in one of the first posts on this blog in 2007. The Upcycle extends some of the key concepts from Cradle to Cradle such as its critical take on recycling as “downcycling”, the elegant notion of designing materials to be easily separated back into “biological nutrients” and “technical nutrients”, and more.  It takes the philosophy of the earlier book about solving sustainability challenges through design…
  • Tournaments and Logs

    With the NCAA basketball tournaments kicking off, here is a post about an exercise I put together for our pre-calculus class last semester on tournaments and logs.  I find a lot of students do not have a good intuitive grasp of the logarithm function and why it might be useful.  This exercise actually originated when my son was around 5 and began racing his toy cars.  (See the video above – it was hard to determine the winner by eye so we filmed it and ran the finish in slow motion; you can freeze-frame it at around 0:02 to see who won.)  He started collecting…
  • Visualizing LPs in Mathematica

    9 Feb 2014 | 2:48 pm
    I’m teaching undergrad linear optimization this semester.  Mathematica can be helpful for visualizing LPs.  It also has some LP solving capabilities.  (Special thanks on this post goes to my colleague Russ Rushmeier, with whom I’m teaching the course, for the example LP, some of the commands, and great discussions.) Here is the example LP we’ll use: max z = x1 + x2 + x3 subject to: 3 x1 + 2 x2 + x3 ≤ 6 x1 – x2 + x3 ≤ 1 x1 + 2 x2 +  x3 ≤ 4 x1 ≥ 0, x2 ≥ 0, x3 ≥ 0. First we’ll plot the feasible region, which is 3-dimensional, using the…
