Manufacturing　companies　rapid　response　to　market　changes　requires　rapid　reconfiguration　of　their　manufacturing　process　to　match　market　demand.　The　product　reconfiguration　model　and　the　generation　of　the　reconfiguration　sequence　are　key　tasks　in　the　reconfiguration　process.　The　assembly　and　disassembly　of　various　products　were　analyzed　to　develop　an　effective　Petri　net　based　method　to　describe　the　structure　of　reconfigurable　products　and　to　represent　the　reconfiguration　of　interfaces.　A　sequence　generating　algorithm　was　developed　which　analyzes　the　economics　of　the　reconfiguration　cost　matrix　to　search　for　the　best　reconfiguration　path.　The　classic　driver　struts　of　a　reconfigurable　parallel　machine　were　analyzed　to　show　that　the　method　is　applicable　and　effective.
