Product scheme multi-index evaluation method considering order relation analysis

The invention discloses a product scheme multi-index evaluation method considering order relation analysis. The method comprises the following steps: firstly, collecting a data source, establishing a traceable relationship between demands of a demand model, and controllably transmitting the demands; carrying out functional decomposition on the demand model until multifunctional indexes which can be used for scheme design by designers are obtained; According to the invention, a multi-index weight evaluation design scheme is adopted, an index evaluation matrix is established, normalization processing is carried out to eliminate non-university, an order relation analysis method is adopted to solve index weights, and a comprehensive evaluation value of each scheme is calculated. According to the method, innovative demand modeling and analysis specifications can be formed in product research and development, scheme evaluation can be simply and quickly carried out in the initial stage of product scheme design, and
