2018 INFORMS Government & Analytics Summit: a recap

I chaired the 2018 INFORMS Government & Analytics Summit, an outreach event to government policymakers and Congressional staffers about how operations research can save lives, save money, and solve problems. It was a blast. Here is a recap of the event. Please visit the website for more information and to find recordings of the talks that will be posted soon. INFORMS Executive Director Melissa Moore kicked off the Summit with the following video:

I gave a few opening remarks and gave a quick, non-technical overview of operations research and analytics:

Secretary Anthony Foxx and General Michael Hayden gave the two keynotes that were the center of the Summit. Both speakers were experienced, understood the value proposition that OR and analytics offer to government officials and policymakers, and are dynamic and engaging speakers.

Former Transportation Secretary Foxx focused on transportation, and he emphasized the importance of integrating transportation solutions. In the United States, transportation is decentralized, with decisions, operations, and maintenance being made by many players, including the Federal government, local governments, and the private sector. A challenge is in developing a cohesive transportation plan with so many players. It is further compounded by transportation data that is collected and owned by so many of these players and stored at various sites. Yet Foxx was optimistic about our ability to bring these transportation issues together and solve problems. Foxx noted, “Waze knows more about transportation activity than I ever knew as Transportation Secretary.”

Foxx noted that transportation is not just a transportation problem. Transportation plays a key role in building communities, should be people-centric, and impacts community health. Transportation solutions should strive to build better communities, not just expand transportation infrastructure. He discussed the smart city initiative as an avenue to incentive cities to develop plans that integrate transportation plans with other objectives.

General Michael Hayden’s talk focused on guiding policy decisions in a post truth world. Intelligence is centered on making fact-based decisions and in collecting facts and expert judgement that are consistent with the facts. We increasingly live in a post-truth world, where decisions are made on feeling, emotion, loyalty, tribe and identify. These factors increasingly inform our truth, not the facts.

General Hayden’s talk was fascinating and philosophical at times. He mentioned Oxford Dictionary’s word of the year (post-truth) and discussed how the Enlightenment philosophy based on truth, data, hypotheses, and validation inspired our founding fathers. He discussed the flow of information and ideas as a system with reinforcement, cycles, and feedback loops. He views information flow as a structured system. He noted that intelligence is pessimistic and policy is optimistic. I wholeheartedly agree with the latter; I even wrote a blog post about it.

Hayden ended his talk with advice on how to work with decision makers. As NSA director, he worked with many decision-makers who were not in his field and not always enthusiastic about the facts and analysis he brought to the table. He found it helpful to use intelligence as a way to bound the possible policy decisions. By putting a box around the set of feasible policy decisions, he could help rule out bad and disastrous decisions from consideration. This also helped the decision-maker (often, a President) feel like the one in charge with input from an intelligence expert, which was helpful in facilitating productive conversations.

The three panels focused on transportation, national security, and healthcare. The INFORMS member experts and moderators were outstanding!

As chair, I would like to mention that we were fortunate to have many nominations and would have liked to have more opportunities to participate in the Summit. Moving forward there will be other opportunities to support INFORMS’ advocacy activities. We look forward to the chance to involve even more members as we work to help make sure policymakers in Washington better understand and appreciate how they can leverage O.R. and Analytics to help save lives, save money and solve problems.

I want to thank the INFORMS Staff and especially Jeff Cohen for making the INFORMS Government & Analytics Summit a reality.




Translating engineering and operations analyses into effective policy

I am presenting at the AAAS Annual meeting in a session entitled “Translating Engineering and Operations Analyses into Effective Homeland Security Policy” with Sheldon Jacobson and Gerald Brown:

In my talk, I will discuss three research questions I have advanced:

  1. How can we more effectively perform risk based security?
  2. What is the optimal way to allocate vehicles to emergency calls for service?
  3. What is the optimal way to protect critical information technology infrastructure?

My slides are below.

what I learned from preparing for a semi-plenary talk

I recently blogged about a semi-plenary talk I gave at the German OR Society Conference. This post is about the process of preparing for that presentation.

First I thought about the story I wanted to tell. I’ve given a lot of research talks before. I understand the general plot of a research talk, but a semi-plenary was not a regular research talk. I wasn’t initially sure how to tell a story in a new way. I asked a wise colleague for advice, which was excellent:

  1. Think about your favorite plenary talks. Model your talk after that (including the amount of math to include in the talk).
  2. Think of the talk as a series of 30 second elevator talks. Let those messages structure your story.
  3. Your audience will want to feel that they’ve learned something. What are the takeaways?

I found that creating an initial set of slides wasn’t so bad once I decided in the story I wanted to tell. I have given so many talks before that I had a huge set of slides that I could pull from. I had too many slides and could not fit into the time slot, and editing and pruning my slides was pure torture.

A few months ago, I read a post by an academic blogger who had recently given a plenary talk. I can’t find the post now but I remember that it took about 40 hours to create a one hour talk. This reminded me of an earlier post on teaching MOOCs (How college is like choosing between going to the movies and Netflix), where an enormous amount of time goes into a single lecture.

Here is why it took so long. I noticed that every time I removed a slide or combined a few slides into a single slide, it affected the story narrative in a major way. In a regular research talk, I find it easy to pick a few details to leave out. Not the case this time. Rather than condense the story, I eventually left some topics out all together or turned the insights from a  paper into a couple of bullet points on a slide. Finding the right balance of detail and insight was a constant challenge.

I ended up having almost no math in my talk. I decided that insights were more important that going through technical details.

I recreated almost all of the visuals from my slides in previous talk. It’s not that my visuals were total crap, it’s just that there was just too much detail and notation in previous figures I made for research talks. I didn’t want confusing visuals getting in the way of the story. Sometimes I added a picture to illustrate an idea or insight that was technical in nature rather than launching into a long narrative to explain a simple point. Here is an example of a new visual explaining the concept of ambulance response times and coverage:

Example of a conceptual slide I used in my talk.

Other times i just needed to make a simpler version of a figure or table that allowed me to look at a single curve or to compare two things, instead of a busier figure that works in a regular research talk. At one point, I changed a figure with four subfigures into a single figure by omitting the other three subfigures. I make nearly all of my figures with Matlab and save my code so that I can easily recreate figures for presentations or paper revisions. Remaking figures wasn’t too taxing, but remaking a lot of figures took some time.

Finally, I learned so much about my research when giving this talk. The end my my talk answered two questions:

  1. Where is emergency medical service research in OR going?
  2. Where does emergency medical service research in OR need to go?

I think about high level issues all the time (after all, I frequently write proposals!). But this was different: I was talking about places where this entire line of research is going, not just mine. When I was answering the question “Where does emergency medical service research in OR need to go?” when making my slides, I learned that my research had already made progress in the right direction. Not all of my ideas are in line with the where this line of research needs to go, and it was worthwhile to realign my priorities.

land O links: #informs2012 edition

Here are a few miscellaneous links from the 2012 INFORMS Annual Meeting.

  • Mike Trick writes about Al  Roth and Lloyd Shapley, winners of the 2012 Nobel Prize in Economics. Both are well-known in OR/MS circles and have strong ties with INFORMS. Mike notes that this may be the closest we’ve gotten to an OR Nobel. Congrats Roth and Shapley!
  • INFORMS has a video channel that is full of short videos, some of which are from the conference. Here is one about the INFORMS members who received the Nobel Prize:

  • In case you missed it, I urged attendees to register for the communities that interest them when they register for INFORMS. If a community represents an area that is near and dear to your heart, the best way to support them is to be a member. Strength in numbers matters: larger communities carry more weight with INFORMS.
  • @ORNinja had the best tweet of the conference. Nathan Brixius elaborates on this tweet.
  • Tallys Yunes has nice posts about Monday and Tuesday at the conference
  • Tallys made a video about the Annual Meeting before the conference. If you haven’t seen it–or if it didn’t make sense prior to the conference–watch it below:

A post from the INFORMS computing society conference: are application-oriented conferences too specialized?

I am attending the INFORMS Computing Society (ICS) Conference this week.  This is my first ICS Conference.  In addition to the focus on computing, the conference selected homeland security for its theme, with a secondary theme of energy security.  I initially found it unusual for an already-specialized  conference to have an application area focus.

On second thought, many conferences have application area focuses, such as transportation, health, risk analysis.  The application-focused conferences tend to attract people with a broad range of interests who use a variety of tools.  I suppose that the dual focus on computing would not be too limiting, but homeland security seems more focused than, say, health applications.

As a homeland security researcher, I have to say that I was eventually won over.  The talks were all pretty interesting to me, and there was a strong theme to the talks in nearly every session.  Best of all, conference was populated with other homeland security enthusiasts, so the questions asked during the talks were really insightful.  The audience questions quite often gave me even more to think about than the talks.

Since I am interested in both computation and homeland security, nearly all of the talks appealed to me.  Despite having a mere five tracks, I often had to make some tough choices between talks scheduled at the same time and missed more than a few talks that I wanted to see.

The five concurrent sessions were a nice contrast with the 75 concurrent sessions at at the INFORMS Annual Meeting.  Walking between buildings to session hop is not ideal.  When I started attending the INFORMS Annual Meeting, there were about 50 concurrent sessions, and all sessions fit within one convention center.  I have been hoping for the number tracks to be cut back, but they seem to grow every year.  But this tangent should really be its own post, so I’ll stop reflecting for now and come back to this theme later.

I would like to know if those who are less interested in homeland security enjoyed the ICS theme of homeland security as much as I did.  Given that many homeland security applications are ultimately aimed at managing risk, they have broad applicability beyond homeland security and even extreme events.  So I am not sure if the application was really all that limiting.

I hope not too many were deterred by the application focus.  Did you attend ICS?  If so, what did you think of the homeland security focus?
