Membrane　structure　is　a　kind　of　structure　for　construction　based　on　many　emerging　technologies,　and　this　structure　have　been　totally　adopted　in　the　design　of　National　Aquatics　Center　(cailed　＇Water　Cube＇)　that　is　a　new　venue　for　Beijing　2008　Olympic　Games.　The　construction　of　Water　Cube　and　the　success　of　membrane　structure＇s　adoption　represent　the　highest　level　of　technology　on　civil　engineering　in　China.　For　diffusing　the　benefit　of　emerging　technology　on　civil　engineering,　a　roadmap　of　membrane　structure　should　be　constructed　for　identifying　the　roads　of　industrialization.　The　research　on　the　technology　roadmap　of　membrane　structure　is　complex　system　engineering,　due　to　the　complexities　and　uncertainties　of　membrane　structure.　So　a　strategy　for　this　project　decides　the　production　of　the　roadmap.　The　methods　for　constructing　a　technology　roadmap　mainly　include　the　obtaining　of　experts＇　opinions　based　on　Delphi　and　the　analysis　of　experts＇　opinions　based　on　AHP,　and　then　compile　it　according　to　the　data　analyzed.
