Method for requirements prioritizing based on optimal combination of components

Based on the separable cost_remaining benefit method for multi_objective hydropower projects, an investment distribution model is established applying group decision theory; and an optimal combination model of several investment distribution methods is put forward by using the optimization theory.

The paper is based on the limit theory and former person s research on arithmetic for optimal combination forecasting of non-negative weights.

Through overall optimization on the main highway technical indicators,the optimum combination of technical.

An optimum combination scheme was determined,of which the deflector opening of top mill separator was "6",oxygen content at outlet of economizer 3.

This paper elaborates the incentive theories,analyses the present incentives situation of construction project managers based on the forming of the construction project manager group,the present situation and the ways of incenting the construction project managers,and analyses the ways of incenting them and then formulates optimal portfolio of incentives based on statistical theory.

Language gene method (LGM) and indifference curve method (IDCM) are used to get its optimal portfolio investment proportion.

In this paper,we analyse the shape of Non-discrimination curve and its reason of formation from the relation of Non-discrimindation curve and risk security,then replace the Non-discrimination curve,directly research on the optimal portfolio of much risk security on the efficient frontier.
