Abstract: To fully and reasonably consider competitive information of Technical Characteristics(TCs)in House Of Quality(HOQ), and properly determine the final priority of TCs, an integrated methodology for determining the final priority of TCs based on uncertain linguistic information was proposed. The unbalanced uncertain linguistic variables was used to represent technology competitive evaluation given by experts, and a optimization model for determining technology competitive priority of TCs was built, and this model was solved by utilizing Lagrange function. Based on uncertain linguistic information decision theory, the Improvement Goal of Competitive Performances(IGCP)to realize TC was analyzed in qualitative and quantitative way. Analytic Hierarchy Process(AHP)was used to synthetize the Basic Priority Ratings(BPR)of TCs, the Normalized Technology Competitive Priority(NTCP)of TCs and the priority ratings of achieving the IGCP, and therefore the Normalized Priority Ratings(NPR)of TCs was determined. A new car headlight development was taken as an example to show the feasibility and effectiveness of proposed method.
