ScienceDaily: Techniques For Making Barbie Dolls Can Improve Health Care

From the article:

"By the end of the decade, the health care industry will realize that operations research, IT, and other advanced techniques that manufacturers have been using for 15 years to reduce the cost of making items like toys and computer chips will also improve health care delivery," said operations researcher William P. Pierskalla, the John E. Anderson Professor and former dean of the Anderson School at UCLA. "These techniques offer major cost, quality, and access improvements to the healthcare system."

The Hindu Business Line : Reliance refining margins rise as light, heavy crude prices diverge

From article:

"At RIL, there is always a linear programming that is under way, based on the world crude prices and the product demand pattern. The return on the rather high investment made in infrastructure was paying dividends, especially when the delta between the price of sour and sweet crude was significant - a direct corollary of rising crude prices," an analyst said.

WSJ.com - Plane Geometry: Scientists Help Speed Boarding of Aircraft

2005-11-02T07:27:00.000-08:00

Operations Research (O.R.) cuts turn-around time of aircraft, "can add up to tens of millions of dollars." This research has been published in the journal Interfaces as well.

From the article (click the title above to go to the whole Wall Street Journal article from 11/02/2005; subscription required):

Mr. van den Briel's research has led to an innovative boarding system at America West Airlines called "reverse pyramid." The first economy-class passengers to get on the plane are those with window seats in the middle and rear of the plane. Then America West gradually fills out the plane, giving priority to those with window or rear seats, until it finally boards those seated along aisles in the front.

Anthony V. Mulé, senior vice president for customer services, says the system, introduced in 2003, has saved at least two minutes in boarding time. "This is a great illustration of how science helped improve both efficiency and customer service," says Mr. Mulé.

Mr. van den Briel is one of a small cadre of experts in the science of airline boarding. Their research has upset much of the conventional wisdom about how to get people quickly into their seats. Boarding from the rear to the front, still standard practice at many American airlines, is almost certainly not the fastest way, these scientists say. Among the faster methods may be letting everyone board randomly or calling out each individual seat number.

Interesting Application of Monte-Carlo Simulation. From the article:
"The potential megawatt (MW) capacity of the Blue Mountain reservoir has been estimated by Monte Carlo simulation to have a minimum value of 30 MW (90% probability) and a most likely value of 47 MW. This is based on volumetric estimates of heat in place assuming an area of 5 to 8 square kilometers (2 to 3 square miles), a reservoir thickness of 350 to 1,500 m, an average reservoir temperature in the range of 145 to 220 degrees C."

From the article:
Time was when you would use simple average stock-and bond-market returns to calculate your investment goals. Stocks have risen on average 12.5 percent since July 1932 and bonds have gained on average 5.5 percent, says Ibbotson Associates. But in reality, stocks behave much differently, rising 54 percent in their best year and falling 35 percent in their worst year.

That's why most experts, including Susan Hirshman, managing director JPMorgan Fleming Asset Management in New York, recommend using a "Monte Carlo simulation" to predict whether you will build a sufficient nest egg.
