The　traditional　methodology　on　risk　analysis　in　construction　project　feasibility　research　has　remained　for　a　long　time　in　the　atmosphere　of　qualitative　analysis.　A　thorough　quantitative　analysis　approach　in　the　same　field　has　been　carried　out　in　this　paper　based　on　the　properties　and　mechanisms　of　value　mining.　Taking　advantages　of　value　mining　theory,　the　practical　evaluation　on　potential　revenue　and　predictable　risk　of　construction　project　has　been　put　forward,　and　the　optimization　among　various　schemes　for　construction　project　feasibility　research　is　proposed,　under　the　principles　of　multi-target　fuzzy　decision　making　and　satisfaction　degree　of　value　mining.　©　2010　IEEE.
