Semiconductor wafer fabrication probably includes the most complex and constrained
manufacturing processes due to its intricate and time-varying environment. This paper
focuses on time constraint tunnels (TCTs), which can have a very high impact on the yield
and reliability of final products. More precisely, the original problem faced by managers of
controlling the release of multiple lots in a TCT is addressed in the context of a wafer facility
operating in a High-Mix Medium-Volume manufacturing environment. To support the …
