Abstract

The scale, scope and complexity of the manufacturing operations in a semiconductor fab lead to some unique challenges in ensuring product quality and production efficiency. We describe the use of various analytical techniques, based on data mining, process trace data analysis, stochastic simulation and production optimization, to address these manufacturing issues, motivated by the following two objectives. The first objective is to identify the sub‐optimal process conditions or tool settings that potentially affect the process performance and product quality. The second objective is to improve the overall production efficiency through better planning and resource scheduling, in an environment where the product mix and process flow requirements are complex and constantly changing.

The effect of human behavior on malaria infection was investigated in a holoendemic area in the Solomon Islands, using a newly developed mathematical model based on the results of blood examinations and 2 weeks of direct observations. The present study indicated that the place where individuals spen
