<strong>the</strong> associated costs, risks and revenues. While methods are proposed for design<strong>in</strong>g<br />

IVHM systems, <strong>the</strong>se have not yet significantly impacted <strong>vehicle</strong> design practice.<br />

IVHM can improve both <strong>the</strong> cost-effectiveness <strong>of</strong> new and legacy <strong>vehicle</strong>s by l<strong>in</strong>k<strong>in</strong>g<br />

ma<strong>in</strong>tenance, operations, and logistics to <strong>the</strong> present and future health <strong>of</strong> <strong>the</strong> <strong>vehicle</strong>.<br />

However, <strong>the</strong> costs <strong>of</strong> <strong>the</strong> technology are potential barriers to widespread adoption. There<br />

is a need for consolidated tools and methodologies for <strong>the</strong> design <strong>of</strong> IVHM applications.<br />

A better understand<strong>in</strong>g <strong>of</strong> <strong>the</strong> relationship between IVHM and emerg<strong>in</strong>g forms <strong>of</strong> service<br />

contract<strong>in</strong>g would also facilitate a wider adoption <strong>of</strong> both. Recent advances <strong>in</strong> sensor,<br />

communication and s<strong>of</strong>tware technologies have enabled a paradigm shift to take place <strong>in</strong><br />

<strong>the</strong> way complex assets are designed, operated and ma<strong>in</strong>ta<strong>in</strong>ed. Str<strong>in</strong>gent health<br />

management requirements are be<strong>in</strong>g placed on <strong>the</strong> development <strong>of</strong> new <strong>vehicle</strong>s [10] and<br />

IVHM <strong>of</strong>fers an opportunity to improve <strong>the</strong> management <strong>of</strong> products thorough <strong>the</strong>ir<br />

lifecycles, extend<strong>in</strong>g beyond <strong>the</strong> field <strong>of</strong> <strong>vehicle</strong> systems to <strong>in</strong>clude any complex<br />

technical asset.<br />
