The board retained Operations Research/Education Laboratory at N. C. State University to make a complete study of the Bladen school enrollments and the present and projected population status of the county, and then make recommendations on a new plan of districts.

"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."

Video-on-demand services and digital video recorders are seen undercutting traditional linear programming schedules, which networks use to set advertising rates. Advertising-supported television continues to drive the bulk of programmers' sales.

"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.
A popular workshop feature allows producers to enter information about their own farms into Purdue's linear programming software. Using the program, growers can test some of their own management situations, such as the optimum size of their operation for their current resources or whether buying a certain new technology will be profitable.

A second project under way involves deploying "package-flow" technology in UPS's package centers, entailing a suite of custom-built software that combines operations research and mapping technology to optimize the way boxes get loaded and delivered. One goal is to cut the distance that delivery trucks travel by more than 100 million miles each year.
Institute for Operations Research and the Management Sciences sponsors this annual competition for the Franz Edelman Award for Achievement in Operations Research and the Management Sciences. Finalists are the Athens 2004 Olympic Committee, Eli Lilly, General Motors, Nanzan Educational Complex, Proctor & Gamble, and Swift & Co.

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.

Potential Impact of a Targeted Cardiopulmonary Resuscitation Program for Older Adults on Survival from Private-residence Cardiac Arrest -- Swor et al.
Medical Research Application of Monte-Carlo Simulation. From the article:
Monte Carlo simulation (n = 10,000) and sensitivity analyses (n = 40) were used to assess median and the empiric 95% confidence intervals [CIs] for incremental survival with either intervention.
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.
Interesting article about the integration of IT, Operations Research, and Operations Management in creating competitive advantage.

Real-Life Optimization. This is a Linear Programming-Based Solution. From the article:
Specifically, the company is changing how (and when) it decides to allocate logs to manufacturing facilities, what products to produce and what markets to sell them in. "What we are talking about is optimizing the allocation of wood fibre with the aim of maximizing net cash flow from across all of our operations," explains Ian Taviss, JDI Management Forester, who is spearheading the program to change wood allocation decision-making within the organization.

The trick is creating the optimal balance of low-end and high-end storage to perfectly match the value of corporate data, Zimmerman says. "There's some real linear programming that needs to go on to find the optimal mix of prime, secondary and tertiary storage," he says. "Nobody has an algorithm for the timed value of a piece of information. "
