IDENTIFYING PRODUCT AND PROCESS STATE DRIVERS I...

The book reports on a novel approach for holistically identifying the relevant state drivers of
complex  multi-stage manufacturing systems. This approach is able to utilize complex  diverse
and high-dimensional data sets  which often occur in manufacturing applications  and to
integrate the important process intra- and interrelations. The approach has been evaluated
using three scenarios from different manufacturing domains (aviation  chemical and
semiconductor). The results  which are reported in detail in this book  confirmed that it is
possible to incorporate implicit process intra- and interrelations on both a process and
programme level by applying SVM-based feature ranking. In practice  this method can be used to
identify the most important process parameters and state characteristics  the so-called state
drivers  of a manufacturing system. Given the increasing availability of data and information 
this selection support can be directly utilized in  e.g.  quality monitoring and advanced
process control. Importantly  the method is neither limited to specific products  manufacturing
processes or systems  nor by specific quality concepts.
