Sustaining Supply Chains in Disasters and Post Hurricane Sandy

One week after Hurricane Sandy made landfall in the mid-Atlantic states of the United States there are still over a million electric power outages.

With cold temperatures, shortages of fuel for both vehicles and generators, and now a shelter crisis, due to so many homes being destroyed in parts of  New York and New Jersey, and major impacts on transportation infrastructure from bridges to subways, plus a nor'easter storm forecast for mid-week, I am wondering why more was not done and is not being done to help those in the recovery process.

Our relatives in New Jersey are still without power one week after losing it and friends have had to seek shelter since they are now homeless.

Clearly,  there are issues of serious resource misallocations as well as information shortages, among other shortages. Trained personnel are needed to restore power where it is needed and fuel needs to be transported and people informed as to where they can obtain it. Information needs to be provided to those who have lost their abilities to receive news and to receive communications electronically.

There are also questions, in certain communities,  surrounding how, if any, prioritization was done, in terms of restoring electric power, delivering fuel and other resources.

Commercial supply chains are different from humanitarian ones  and  we need to learn from previous disasters.

Different organizations can accomplish much more through synergistic teaming.  and it is good to see the military, including the National Guard, making extraordinary efforts to assist after this extraordinary disaster.

I was interviewed by Mr. Michael Breen for an AMS podcast on Sustaining the Supply Chain and the podcast can be accessed here.

There was also a recent special issue of the journal Transportation Research A on Network Vulnerability of Large-Scale Transport Networks in which Patrick Qiang and I published the paper, A bi-criteria indicator to assess supply chain network performance for critical needs under capacity and demand disruptions.

In this paper,  we constructed  a performance indicator in the case that demands for critical needs products (water, food, medicines, etc.) can be satis fied. We then considered the case when not all the demands can be satis fied and de fined another performance indicator. In order to assist cognizant organizations, such as governments, relevant corporations, and NGOs, to better manage critical needs supply chains, a bi-criteria performance indicator was, subsequently, proposed in this paper. This indicator synthesizes the preceding two in that it considers the following factors:

  • Supply chain capacities may be a ffected by disruptions;
  • Demands may be a ffected by disruptions; and
  • Disruption scenarios are categorized into two types.
We also showed how our supply chain performance indicators could be applied in practice and now we are seeing yet another disaster. More severe scenarios can be expected, given climate change, which is upon us and our communities. 

Time to harness all of our energies and expertise to minimize the damages, the pain, and the suffering.

Investing in Science for Economic Growth and Our Future in the Aftermath of Hurricane Sandy

The power had gone out in our neighborhood last night in Amherst, Massachusetts at 8PM sharp.

We had been expecting that it would, at some time, given the massive size and strength of Hurricane Sandy and had planned and prepared accordingly. We had purchased supplies even in Pennsylvania, where we had spent the weekend, filling up our cars with gas, getting enough cash from the ATM machines, stocking up on water and nonperishables as well as flashlights and extra batteries.  We had worked furiously yesterday at home, taking advantage of what electric power provides and knowing full well the difficulties presented when it is not available. My husband's university and mine (UMass Amherst) were closed yesterday due to Hurricane Sandy.

Only a few days before,  I had been speculating whether this October storm would be worse than that of our freaky Halloween snowstorm of a year ago when we were without power for over 72 hours and many of our friends in Connecticut for over 8 days!

We were prepared for this one, in part, because scientists had been informing us regularly as to the status of the weather forecasts for this major hurricane. I do admit that I followed closely the predictions of the European weather forecasting computer model versus the US one and was pleased to hear when they were "converging"  since the information that was being provided allowed for emergency preparedness of many organizations and communities.

Usually, we speak of algorithms converging to a solution, but, in this case, different mathematical models were converging to similar forecasts and information for the storm that is now being estimated as having caused over $20 billion in damage and it is not even over yet. Colleges and universities have shut down for 2 days -- including 5 Ivies -- my alma mater, Brown University, the University of Pennsylvania, which we had watched row in the Schuykill rowing regatta just this past Saturday in Philadelphia, along with many other college teams, and Princeton University (that also had its own regatta on Sunday), as well as Columbia University and Yale University. The breadth of the storm is affecting 900 miles and has produced low pressures never before measured.

Millions in the northeast of the US are without power and certain colleges are still without power.

In NYC, backup generators for hospitals failed resulting in superhuman efforts by the medical staff to evacuate and to keep life support systems for patients, including newborns, functioning.

The New York Stock Exchange has now been closed for the longest period for a shutdown due to weather since 1888!  Transportation in the major cities of the Northeast from Washington DC to Philadelphia and NYC has ground to a halt with mass transit systems shut down because of the anticipated flooding, which has now come to fruition, and bridges and tunnels are closed because of the winds of over 60 miles an hour that have swept over our communities and cities. Highways that we were on just two days ago in Connecticut were closed yesterday to all traffic except for emergency vehicles as was the Tappan Zee bridge and we drove over it this past Sunday.

Beautiful shorelines in New Jersey from Atlantic City to Long Island, Connecticut, and Rhode Island, now under water, and covered with debris, will be unveiled in new realizations as the tides pull back.

Today, after the sun rises, many of us will venture out of our shelters to survey the landscape, if we can, to see if and how it has been changed by Hurricane Sandy, which, as a natural disaster, will break records in terms of economic and physical impacts.

Last night, when the power failed, my husband and I hunkered down with a big battery-operated lamp and one flashlight each to read newspapers (good backup plan since we could not then be reading news online since our power had failed). 

An OpEd in The New York Times, "Science Is the Key to Growth," by Dr. Neal Lane, a former Director of the National Science Foundation (NSF) and the Chief Science and Technology Adviser to President Bill Clinton, caught my eye. In his thought-provoking OpEd, Lane writes:

Scientific knowledge and new technologies are the building blocks for longterm economic growth -- "the key to a 21st century economy," as President Obama said in the final debate.

He goes on to emphasize that the private sector can't do it alone and although companies translate our scientific discoveries into products federal investment in R&D, especially in basic research, is critical to their success -- just think of Google, for example, which he notes was started by two former grad students, whose names are now known by everyone using a computer, who were on NSF graduate fellowships!

Investments in science create jobs in entirely new industries and we deserve and need to be again "a land of rewarding jobs."  As Dr. Lane eloquently concludes: "we need to understand the basic investment principle in America's future: no science, no growth."

The electric power in our home was restored at 4AM and I hopped out of bed to get back to work.

Without science, there would be no weather forecasting -- there would be no modern healthcare -- there would be no well-thought out and executed evacuation plans -- and the same holds for recovery and reconstruction efforts.

The disasters of last year as well as the research that we had done for our Fragile Networks book motivated me to prepare a new course, Humanitarian Logistics and Healthcare, in which the students learned about crisis management and disaster relief and one of the student team projects was on the evacuation of a hospital.  This year, although I am on sabbatical, I have been invited to teach a condensed version of the course at the Vienna University of Economics and Business, where a former doctoral student of mine, Dr. Tina Wakolbinger, who received a PhD from the Isenberg School of Management, with a concentration in Management Science, is now a Full Professor. I will have an immense amount of material to cover and will definitely include topics about Hurricane Sandy.

Science uncovers frontiers and it also helps us to undetsand what makes for resiliency and how to prepare for emergencies and crises.

As I have written before, why can't the US be more like Sweden, where I spend a lot of time as a Visiting Professor and  which Dr. Lane also singled out, along with Israel, Japan, and South Korea in terms of investments in national research and development.

Thank you, Dr. Neal Lane, for speaking out!

What a Difference a Day Makes -- from the Schuykill Regatta to College and University Closings Because of Hurricane Sandy

Being a professor one has colleagues and friends in many colleges and universities around the globe -- so when an event happens somewhere, chances are high that you may know someone there.

Now with Hurricane Sandy expected to affect over 60 million people with its fury in the Northeast many of us are getting prepared.

However, only yesterday, we were in Philadelphia at the Head of the Schuykill Regatta watching so many rowers from the Northeast (men and women of all ages, including numerous college and university teams) compete in an atmosphere of warm weather, numerous spectators, and beautiful Fall foliage. We saw friends from many colleges that we had gotten to know through our daughter's elementary school and high school in Deerfield, Massachusetts. I was amazed at the boathouses that line the river and the beauty of Fairmont Park.My college roomate at Brown University was on the crew team so I have come to appreciate the sport.

And today, driving back from eastern Pennsylvania back to western Massachusetts, we saw state of emergency signs in New Jersey, in Connecticut, and we heard Governor Andrew Cuomo of NY announce that the subways were shutting down in NYC tonight at 7PM. Now Governor Deval Patrick has declared a state of emergency in Massachusetts. We also saw electric power company trucks from Georgia and Tennessee  in caravans as we were driving north.



Crew teams were rowing yesterday for colleges from UPenn to Lafayette College, among others, which are now closing for tomorrow because of Hurricane Sandy.

The University of Massachusetts Amherst is closed tomorrow (Monday) and my husband's university in Connecticut has cancelled classes for the next three days.

What a difference a day makes!

What will await us as when we wake up tomorrow and on Tuesday?!
