Its principle is the equal bidding price criteria in the case of clearing based on the unified m arginal cost,while it is the equal incremental cost criteria for generators in the case of clearing based on the practical generators bidding.

The quotation rule mapping between the quotation formula and the request-characteristic variable as well as the product module is obtained based on the feedback amendatory coefficient,and the quotation method based on feedback amendment for multi-specification and small-batch mechanical production is realized.

Through establishment of quotation rule and the mapping between request-characteristic variable and quotation of product module, a rule-based quotation method is put forward, which is a new quotation method for mass customization.

From frequency equation represented by flexibility matrix,according to equivalent rules of equal structure period,total base shear and top-point displacement,three-degrees equivalent model for regular high-rising isolated structure was deduced,and simplified computing formula for model parameters has been given after numerical analysis.
