Doing by virtual experimenting

China has become and international center for semiconductor assembly and testing mainly due to relatively cheap labor and easy access to a huge market. With increasing facility and capital equipment investment, the demand for soft skills in complex production management is also growing rapidly because the profitability is highly dependent on process efficiency. The complexity of managing semiconductor production has been well recognized. Although simulation could potentially generate enormous benefits, the people that can apply simulation technology to draw insightful conclusions are still a scarce resource, especially in an emerging market such as China. An answer is to structure the simulation experiments in a repeatable and controllable manner, which provides a user-friendly and easy operational interface. A reactive scheduling system has been proposed by a number of academic researchers and industrial practitioners.
