A Flexible Inspection System (FIS) is defined as one where the inspection routines are determined just prior to performing the inspection. That is, the inspection effort is allocated dynamically using the information generated by the inspection process itself. A typical objective to achieve in inspection routine generation is the minimization of total production costs. However, information on costs is often difficult to obtain. Thus, alternative objectives should be sought. In this system, the maximization of an information gain factor (G) is proposed as the objective to optimize. The use of this factor would allow the implementation of efficient algorithms for inspection routine generation, a characteristic that is indispensable for implementation of real-time inspection control.
