Abstract

Structural health monitoring (SHM) systems depend critically on using the correct number of sensors and on positioning them appropriately on the structure. A rigorous approach to this problem requires an optimization methodology as described in this article. The article begins with a definition of the problem and provides a literature review covering relevant methodologies. The basic theories of the main approaches are then discussed in more detail. Finally, the article provides an illustrative case study of a combinatorial optimization method based on the problem of impact location on a composite panel.
