The remarkable improvements in mixed-integer programming software that started in the late 1990’s have continued, unabated. These developments are enabling a new breed of applications to daily business operations and promise to make optimization a more central part of managing a modern enterprise. We will give several specific examples, and examine in some detail one successful, running application for short-interval detailed production scheduling in semiconductor manufacturing. Modern 300 mm semiconductor manufacturing facilities, or Fabs, cost upwards of $4B to construct, and 90-95% of all shop-floor work is now being automatically dispatched in several such Fabs worldwide using optimization.
