"The Mayo Clinic Department of Orthopedic Surgery was facing low utilization of their operating rooms (ORs) for spine surgical procedures, combined with fluctuating empty days and days with overtime to complete scheduled surgeries. Extremely long days ended up being unsafe days with increased provider fatigue and higher likelihood of errors. Investigation revealed the cause to be inaccurate estimation of surgical and non-surgical duration and scheduling of surgeries rather than limited surgery demand. Existing scheduling optimization research in the literature was inadequate, as they provided a single "optimal" solution. Often, the single optimal solution was not satisfactory to the patients and the providers. The team 1) conducted descriptive research using historical data to identify clinical and operational factors; 2) developed and implemented predictive models for the duration of surgical and nonsurgical times in the OR based on these factors; and 3) developed and implemented a prescriptive scheduling search algorithm that suggests multiple slots for a given surgery thereby providing flexibility while ensuring high probability of completion of surgical day without much overtime (completion closer to 5 pm)."

"We describe a software application that enables owners of generation output from a virtualized Federal Columbia River Power System to safely operate the system while also shaping the generation to meet their energy and economic needs. The application, known colloquially as The Optimizer, employs modern Operations Research techniques to convert a highly non-linear problem into a linear one so as to create a robust solution for the entire, six-dam system on an hourly basis; over a ten-day time horizon; within seconds to minutes. The tool permits two operators to manage and optimize the entire generation portfolios for nine utilities simultaneously in a very stringent time frame around the clock, and enables planners to ensure that the operation of the river meets all of the requirements for flood control, fish management, electrical reliability, safe dam operation, and recreation under high degrees of uncertainty. As a result, the Optimizer allows utilities to integrate renewable, environmentally friendly wind and solar generation into their resource portfolio with hydro generation and empowers fast decision making and adaptation to rapidly changing conditions."

"We present the problem of scheduling crash tests for new vehicle programs at Ford. We developed a completely custom-made scheduling system that transforms a labor-intensive scheduling process relying on high levels of expertise, to a more automated one that utilizes optimization and institutionalizes expert knowledge. Our system enables engineers and managers to consider multiple scheduling scenarios, using efficient interfaces to specify problem instances and efficient methods to solve them."

«Проблема сопряжения членов экипажа авиакомпании состоит в том, что необходимо создать оптимальные пары, которые бы удовлетворяли требованиям к комплектованию рейса. Точный состав экипажа, необходимый для полета, часто варьируется в зависимости от пар, которые его формируют. В отличие от обычных подходов, Saber Long Haul Pairing Optimizer моделирует эту зависимость явно и использует сложные методы ветвей и цен. Мы используем реальные примеры авиакомпаний, чтобы показать, что наше решение приносит значительную экономию для авиационной отрасли ». "The airline crew pairing problem is to generate optimized legal anonymous pairings that cover the flight complement requirements. The exact crew composition needed on a flight often varies depending on of the pairings that cover it. Different from the conventional approaches, Sabre Long Haul Pairing Optimizer models this dependency explicitly and uses sophisticated Branch and Price techniques. We use real airline examples to show our solution brings considerable savings to the airline industry."

В этой статье анализируются методы управления запасами при самофинансировании фирм, чьи решения о пополнении запасов ограничиваются денежными потоками, которые периодически обновляются после покупки и продажи в каждом периоде. Разработанные стратегии были использованы для повышения уровня обслуживания клиентов и сокращения удельных затрат.
