Looking Forward to Delivering My IFORS Distinguished Lecture in Buenos Aires!

I was deeply honored to have been selected an IFORS (International Federation of Operational Research Societies) Distinguished Lecturer.

I will deliver my Distinguished Lecture at CLAIO, which will take place in Buenos Aires, Argentina, December 12-15, 2022. Information on the conference can be accessed here.

The IFORS Distinguished Lecture program started in 1999 and the full list of previous lecturers can be found here. I find it quite remarkable that I have had the pleasure of meeting quite a few Operations Research scholars on this list!

It was such a delight to receive the letter below from IFORS.

The title of my lecture is, "Human Migration Networks: How Operations Research Can Assist with Refugees and Supply Chain Labor Shortages."

I published my first paper on human migration networks, amazingly, in 1989, and the research has continued, with many wonderful co-authors. During the COVID-19 pandemic, our research on human migration networks intensified, because of the additional challenges and also increasing refugee flows as well as labor shortages in many economic sectors around the globe. Even now we are working on another human migration network paper that focuses on coalitions and social welfare.

I have very much enjoyed working on my lecture. It is dedicated to essential workers who have sustained us in the COVID-19 pandemic with acknowledgment of all the freedom-loving people on the planet including those fighting for their freedom in Ukraine. 

Some of the papers that I will be highlighting in my lecture are: a paper published in the Journal of Global Optimization, co-authored with Professors Patrizia Daniele and Ladimer S. Nagurney, on refugee networks, and the paper that I wrote and which was published in Operations Research Perspectives, which integrates human migration networks with labor in supply chain networks.

I will also highlight research that we published in the IFORS journal, International Transactions in Operational Research, on policy interventions for bringing human migration population distributions in line with system optimization.

I very much appreciate that IFORS posted the statement below on Russia's war against Ukraine on its homepage.

Coincidentally, the last time that I was in Buenos Aires, which was in June 2010 for the ALIO-INFORMS Conference, the World Cup was taking place and I blogged the experience. And, now, the World Cup is again taking place, but in the month of December, and in Qatar, and I will be back in Buenos Aires! I leave you with several photos that I took in Buenos Aires.

And congratulations to Argentina for making it to the quarterfinals of the World Cup today!

World Cup Postcard from Argentina -- 1 Month and 1 Day

On June 11, 2010, the 2010 World Cup began and that was the same day that we mailed a postcard to ourselves from Buenos Aires, Argentina, where I spoke at the ALIO-INFORMS conference.

Remember that today is July 12, 2010, the day after the ending of this World Cup in South Africa. I am pleased to report that the postcard that we sent to ourselves (since we love to track how long deliveries can take) arrived today! It took 1 month and 1 day and, strangely enough, it had a side trip to Mexico. Perhaps it was because Argentina beat Mexico in this World Cup?!

We started getting messages from relatives and friends in the past 10 days or so that our postcards to them from Buenos Aires were trickling in.

I wish that there had been a GPS tracker on this card because I am sure that the journey that it took was fascinating from a transportation point of view.

Above is what we are calling our infamous World Cup postcard. We whited out our address, which was present, so that was not the excuse for this extreme snail mail delivery.

At least it did arrive, finally!

Even Hillary Clinton was in Argentina

In honor of the great World Cup win by Argentina today against South Korea to the score of 4-1, I have posted the above photos that I took in Buenos Aires last week where I attended the ALIO-INFORMS conference.

In the top photo above is a nice note from Hillary Clinton who dined at the Cafe Tortoni in Buenos Aires, a cafe that we also had the pleasure of eating at last week. I also recommend La Biela in La Recoleta, a very historic part of Buenos Aires, whose charming waiters gave us many extra pieces of exquisite dark chocolate.

If you'd like to see more photos of Buenos Aires, please see my earlier blogposts. The New York Times has front page coverage today about the Argentine soccer coach, Maradona, and his team's star player, Messi. Maradona, who is considered one of the top former soccer players ever, has promised to run naked through the streets of Buenos Aires should Argentina win the World Cup. He continues to coach his team at the World Cup matches dressed in a gray suit, which, as many have noticed (and despite the elegance of the people of Buenos Aires) does not fit him well.

Also, Professor Peter Lohmander of Umea, Sweden has kindly posted gorgeous photos that he took while at the same operations research conference in Buenos Aires . His photos may be accessed here.

The Greening of the Metropolis

On my flights back from the ALIO-INFORMS in Buenos Aires, Argentina I had the distinct pleasure of reading the latest issue of Bloomberg Businessweek. There was a special segment in it on Clean Energy and an excellent article, "The Greening of the Metropolis." With cities being home to more than half of the world's population and generating more than two thirds of the world's carbon dioxide, greening of our megacities can make a significant difference in improving the environment.

I am hopeful. With the leadership of some of the biggest cities in the world taking proactive, creative steps to reduce emissions, much can be accomplished especially since regions and nations are failing to act.

Kudos to Los Angeles and its mayor, Antonio Villaraigosa, for 1,700 miles of bike paths that are to be completed by 2015, complete with showers and bicycle storage areas.

Bravo to the mayor of Toronto, David Miller, who plans on investing over $1 billion in public transport and environmentally-friendly air-conditioning systems for buildings.

In Tokyo, where, amazingly, 68 percent of the trips are by bike, subway, or on foot, in April a cap and trade system was instituted for carbon dioxide that is city-wide. As for Houston, Texas, where an astonishing 95% of the trips are made by car, at least officials are getting electric cars to reduce emissions.

Robert Doyle, the Lord Mayor of one of my favorite cities, Melbourne, in Australia, plans to bar cars from downtown and to offer incentives for green investments.

Copenhagen, in Denmark, is spending over a billion and a half dollars on bike paths, green energy projects, and retrofitting city buildings.

Amsterdam's infrastructure is being improved to the tune of 1 billion dollars, with its 2,400 houseboats being retrofitted to use electricity instead of diesel.

New York City, one of my absolutely favorite cities, since I grew up in Yonkers, is moving forward with its PlaNYC, to make buildings more energy efficient, power plants more environmentally-friendly, and with tax breaks for the use of solar panels.

Having spent over a week recently in another megacity -- Buenos Aires, Argentina, with about 11 million people in the central and surrounding areas, I know that much needs to be done.

The architecture of this city is stunning as are the neighborhoods with unique identities, and the lively, warm people and culture.

However, the traffic is horrendous with the busses running frequently but on diesel and their evident fumes spewing and belching out. Not only do they emit toxic pollutants but the noise that they generate is substantial. As one former Argentine physics colleague of my husband's, dating back to our Brown University days, told us during a lovely 3 hour dinner in Buenos Aires: when the busses go on strike, the people notice how much cleaner the air gets and how much more peaceful the city is even with more cars! Ironically, in parts of the developing world, getting rid of public transit with aging engines may actually improve air quality.

A better approach (and our colleague told us that he expects that this may happen but it will take about 10 years), is for the city of Buenos Aires (where 1/3 of Argentina's population lives) to purchase busses with the latest green technologies and with quieter designs.

Above are photos taken from the 14th floor of the Etoile Hotel in Buenos Aires where we spent last week. In the photos one can see the famous La Recoleta Cemetery where Eva Peron is buried and the Law School with the big columns, where the operations research conference that I attended and spoke at took place.

My talk at the ALIO-INFORMS conference was on "Sustainable Supply Chain Network Design: A Multicriteria Perspective" and it certainly hit "close to home." The paper is available here and the pdf of the presentation is here.

The Dogs and their Walkers in Argentina

Travel is always eye-opening and opens one's eyes as a travel guide never can.

Having returned from a stay in Buenos Aires, Argentina, where I attended a professional conference, I continue to be amazed at the number of dogs and their walkers that we encountered.

The above photos were taken in Buenos Aires during the past week.

The last photo above is of a dog named Rubio, who lives in the area of Buenos Aires known as La Recoleta, where we stayed at the Etoile hotel. The restaurant goers and waiters at the numerous outdoor cafes keep Rubio well-fed and quite content.

We have been told that the dogwalkers can walk up to 12 dogs at a time. As in North America, the golden retrievers and the chocolate labs love to play with tennis balls.

The World Cup has begun and Argentina

Yesterday, I was still in Buenos Aires, Argentina, spending 1 day touring after the ALIO-INFORMS conference. The city was filled with the Argentine flag and numerous decorations to commemorate the first day of the 2010 World Cup in South Africa. While dining and getting ready to head for the airport to catch a flight back to Dulles and then to Bradley, I caught glimpses of the South Africa vs. Mexico game (score 1-1) and the France vs. Uruguay game (score 0-0) plus some of the opening ceremonies prior.

There are numerous large TV screens in Buenos Aires so that people can watch the World Cup soccer matches.

After a very comfortable flight on United from Buenos Aires to Dulles of about 10 and a half hours but a less than comfortable processing at immigration and security at Dulles with long queues and some sort of strange call for a meeting at 7:00AM for the customs and immigration workers, we just made it to our last flight from Dulles early this morning.

While unpacking, back in Amherst, we caught parts of the Argentina vs. Nigeria game in which Argentina won 1-0 with Maradona as its soccer team's coach.

Above are some photos taken in Buenos Aires, Argentina during the past week marking the World Cup festivities. I am sure that the country is celebrating with its victory in the World Cup today.

The sport of football/fusbol/soccer brings the world together during the World Cup, which takes place this year from June 11-July 11, 2010, in a terrific display of athleticism, cameraderie, appreciation of other cultures, and just pure fun!

At the ALIO-INFORMS conference in Buenos Aires, I very much enjoyed Dr. Celso Ribeiro's plenary talk on how his research was applied to construct the schedules for Brazil's soccer teams, with great success. I especially enjoyed listening to the importance of "fairness" in the schedule and how such constraints were incorporated into the optimization model.

Faces at INFORMS Conference in Buenos Aires

Today was the first day that I could catch my breath since arriving in Buenos Aires, Argentina last Saturday to attend the ALIO-INFORMS conference. The conference was a whirlwind experience with about 1,000 conferees in attendance and just over 100 from the US. Giving a talk, taking part in a panel on international collaborations, plus attending an editorial board meeting, and giving a tutorial on Fragile Networks, still left me some time to attend both plenary talks and keynote talks as well as another tutorial (besides my own).

What a colleague said to me yesterday, I agree with -- in addition to the scientific exchanges that take place at an international conference, what makes such events so special is the people that you meet from colleagues from around the world that you get to see again and to reconnect with to new friends that are made.

Above are some photos taken at some of the above conference events that I mentioned earlier.

More photos and reflections can be found in several of my earlier blogposts.

The atmosphere in Buenos Aires, with the beautiful pale blue sky and the fascinating architecture and boulevards, plus the fantastic food and elegant people (and numerous dogs and dogwalkers), all make for a truly unique and special conference venue.

The Magic of Buenos Aires

The ALIO INFORMS conference that attracted operations researchers from around the world has come to an end. The organizers should be congratulated for an excellent conference. I will be writing additional blog posts about the conference but, in the meantime, in addition to the previously posted photos on this blog from Buenos Aires, Argentina I share some addtional ones with you above.

First 48 Hours in Buenos Aires, Argentina

I arrived in Buenos Aires, Argentina after about 17 hours of travel. It is Fall here but the weather is perfect with sunny skies and temps in the 60s.

The ALIO INFORMS conference has begun and I have met conferees from around the globe.

Above are some snapshots taken in Buenos Aires during my first 48 hours here.

The elegance of the city and its charms are apparent as is the warmth of the people here. Knowing Spanish is a clear advantage and it is great to have an opportunity to speak this language.

Operations Research Tutorials at ALIO-INFORMS Conference

There is a wealth of tutorials at the very soon to take place ALIO-INFORMS Conference, as well as exciting plenary talks and keynote speeches. The venue is Buenos Aires, Argentina, which has been called the "Paris of the South."

The topics of the tutorials and plenary and keynote speeches are varied and exciting and include a wide spectrum: from optimization in sports to portfolio management, OR education, revenue management, dynamic games, humanitarian operations, telecommunications applications, cliques in graphs, among others. The full list can be read here.

Mike Trick has a blog post that he is also off to the conference and has been working on his tutorial.

I am sure that this conference will be covered well by the bloggers in attendance and plan on posting from Buenos Aires!

The tutorial that I will be giving is on Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain Age and I have made the slides available (along with those for a presentation and for the International Collaborations panel that I will be on). An invited paper, based on this tutorial, and in press in the journal, International Transactions in Operational Research, joint with my co-author of the Fragile Networks book, can be downloaded (in pdf format).

International Collaborations Panel

I am very much looking forward to the ALIO-INFORMS Conference that will take place in Buenos Aires, Argentina, June 6-9, 2010. Besides giving a talk on Sustainable Supply Chain Network Design at the conference and an invited tutorial: Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain Age, which is on the theme of my latest book with Professor Patrick Qiang, I will be on a panel: International Collaborations. The panel was organized by Professor Sadan Kulturel of Pennsylvania State University Berks and is sponsored by WORMS (Women in Operations Research and the Management Sciences). Dr. Kulturel has assembled a great group of panelists that I am honored to be included with: Dr. Karla Hoffman of George Mason University, Dr. M. Gulnara Baldoquin of the Higher Polytechnic Institute in Cuba, and Dr. Lorena Pradenas of Concepcion University in Chile. More information on the panelists can be accessed here with a press release from Penn State Berks on this panel available here.

Each panelist will give a 10 minute presentation followed by questions and answers.

My presentation on my personal experiences and reflections on international collaborations is available here (complete with a lot of photos)

I am very much looking forward to this conference and to participating in the panel and discussions and I thank Dr. Sadan Kulturel for organizing this special panel.

Air Travel Disruption Twice As Long as After 9/11 and Counting

The air travel disruptions and chaos due to the ash spewing from the Eyjafjallajokull Volcano in Iceland have now lasted 6 days, twice the period of time that air travel to/from the US was shut down following 9/11. Hundreds of thousands of travelers have been affected, and even the British navy was enlisted to try to ferry some of its stranded citizens (with not complete success). Flowers and farm products are rotting in warehouses in Kenya (since these usually are distributed to Europe by air cargo flights), travelers have been camped out for days in the JFK airport as well as in affected airports in Europe. Artists and musicians cannot make their appointed events in the US. Student groups from the US have had their dream trips to Europe abandoned due to the flight cancellations, and athletes have been unable to compete in the Boston Marathon and in a world skating event in France, since they have been unable to reach their destinations. Of course, academics have also been unable to give talks abroad since their flights have been canceled, as well.

Even President Obama and Chancellor Angela Merkel of Germany canceled their appearances at the funeral of President Lech Kaczynski of Poland and his wife, Maria, who, along with dozens of other Polish dignitaries, perished tragically in a place crash in Russia recently. Chancellor Merkel had to take quite the circuitous route and combination of modes of transportation (even riding a bus from northern Italy to Germany) to make it back from the US because of the air travel disruptions.

The Dow Jones Newswire is reporting that Asian chip and cellphone makers could be affected if the European air space closure does not end soon. Although most electronic products from Asia are shipped by sea, smaller products such as cellphones and ships are transported by air. Samsung spokesman James Chung, was quoted as saying in the report, If this volcano problem lasts longer than expected, it would have a direct impact on Samsung's chip and cellphone exports. The crisis is costing the European economy alone billions of dollars in lost business. Airlines, already suffering from economic woes, are sustaining losses of hundreds of millions of dollars a day.

Now The New York Times is reporting that a new ash cloud is looming from the Iceland volcano whose recent eruption has affected travel and economic activity from Beijing to New York!

While this natural event has been evolving and has impacted broad swaths of the civilized world, and has resulted in major economic damage (plus personal discomfort and dislocation for many), I have been busy at work completing a paper (in which the volcanic eruption is noted). The paper, Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain Age, is a synthesis of my recent work with Professor Patrick Qiang on network vulnerability and robustness and how to identify which nodes and links in network systems (including transportation ones and the Internet) are the most important. The paper also discusses synergies associated with exploiting network structure from corporate mergers and acquisitions to teaming of humanitarian organizations in the case of disasters for logistics operations. The paper is an invited one for the journal, International Transactions in Operational Research, and is the topic of the tutorial that I will be presenting at the ALIO-INFORMS International Meeting to be held in Buenos Aires, Argentina, June 6-9, 2010.

Number 100 -- Oh, the Places You'll Go!

This is my 100th blog post, since starting this blog in January 2009. It is also the first day of September and a gorgeous, crisp day in Amherst, Massachusetts.

The anticipation of the new academic year is clearly in the air!

I decided to name this blog post, "Oh, the Places You'll Go!" after the famous Dr. Seuss book. Dr. Theodore Seuss Geisel was born in Springfield in Western Massachusetts. Western MA is the home of numerous writers and creative folks, and I like to think that academics strive to be creative and productive.

As someone who works on networks from transportation and logistical ones to social networks, I practice what I write about and "preach." One of the best benefits/recognitions of doing solid research is the invitations that one garners and the places that one gets to go to. Indeed, one of my favorite senior colleagues is Professor Martin Beckmann, who is the co-author of the classic book, Studies in the Economics of Transportation, and who was on my dissertation committee at Brown University. He is a brilliant economist whose love of life and good food and friends has taken him around the world. I have been at conferences with Professor Beckmann from Mallacootta in the outbacks of Australia to Stockholm, Sweden, one of my favorite parts of the globe. Although he is in his mid80s he still travels and meets with colleagues in Europe and Asia. He is an amazing scholar, individual, and lover of life! You can see some photos of Professor Beckmann (even with me on a beach in Australia) if you click here and scroll down the page. Professor Beckmann is the recipient of the Robert Herman Lifetime Achievement Award in Transportation Science, among other notable recognitions.

I received an invitation a few weeks back to be a plenary speaker in Cape Town, South Africa, at a conference on life cycle management that will take place next week and, regretfully, I had to turn down this invitation since the new academic year begins next week at UMass Amherst.

Yesterday, I received an invitation to speak at a conference, which also really piqued my interest -- a conference in Mongolia! This conference, which is on Optimization, Simulation and Control will take place July 25-28, 2010, and it is worthwhile to check out the website. However, and this is painful, I have already made a commitment to be a plenary speaker at the Computational Management Science Conference to be held in Vienna, Austria, July 28-30, 2010, an invitation that came first and that I could not refuse.

Also, I have already committed to giving a tutorial on Fragile Networks at the ALIO-INFORMS conference to be held in Buenos Aires, Argentina, June 6-9, 2010, which I am very much looking forward to, and where I will really put my Spanish to practice!

Since beginning this blog, I have in 2009 alone given talks in Dallas, Ithaca, Northfield (Minnesota), Cambridge, Vienna, Rome, New York City, and Chicago and in Davis, California (but virtually). Each year brings new destinations and new adventures! The life of an academic is never dull but does require spirit, flexibility, and stamina! Some photos taken at conferences, speaking venues, and of other activities can be found here.
