Problems solved by technology
If a fixed value is used to describe the index attributes, the investment ranking of the projects to be built may cause a ranking deviation; at the same time, the indicators in the power grid construction project index system have different dimensions and attributes, so the investment ranking of power grid construction projects is a multi-attribute decision-making problem.
[0003] In terms of decision-making methods, existing methods generally focus on objective indicators and fail to take into account the subjective feelings of decision-makers

Embodiment Construction
[0085] Below in conjunction with accompanying drawing of description, the present invention will be further described.
[0086] The invention provides a new method for investment ranking of power grid construction projects, such as figure 1 shown, including the following steps:
[0087] Step 1: Construct a comprehensive evaluation index system for the investment ranking of projects to be built under the new power reform environment. The comprehensive evaluation index system includes qualitative indicators and quantitative indicators; among them, the projects to be built are power grid planning projects waiting to be constructed.
[0088] Such as figure 2 As shown, the comprehensive evaluation index system adopts a three-layer index system, which are target layer, category layer and index layer.
[0089] Among them, the target layer is the first layer, which is the name of the target, specifically the comprehensive evaluation indicators for the grid planning project investme...

The invention discloses a power grid construction project investment ranking new method, which comprises the following steps of: constructing a comprehensive evaluation index system for ranking the investment of each project to be constructed under a new electric power transformation environment, including the qualitative indexes and the quantitative indexes; qualifying the qualitative indexes bya fuzzy number method, and describing and calculating the quantitative indexes by interval numbers; adopting the linear transformation of rewarding good and punishing bad to normalize the data of eachindex; according to the qualitative and quantitative indexes, determining the optimal and worst ideal schemes; using a grey relational method to calculate the approximation degree between the normalized values of each index and the ideal points in the optimal and worst ideal schemes; based on the prospect theory, determining the value function and decision weight according to the optimal and worst ideal scheme, and calculating the comprehensive prospect value of each project to be built; and according to the comprehensive prospect value, ranking the investment of each project to be built. Thebeneficial effects of the present invention are that: the distinguishing precision of the indexes is greatly improved, the investment ranking can consider the risk attitude of the decision-maker, andthe decision-making result accords with the reality better.
Description
technical field [0001] The invention relates to an investment decision-making method, in particular to a new method for investment sequencing of power grid construction projects, which belongs to the field of investment decision-making of power grid construction projects under the environment of new electricity transformation. Background technique [0002] Under the electricity market environment, there are uncertainties in on-grid electricity price, electricity sales, power supply cost, line loss rate, average electricity selling price, electricity purchase price, and power supply reliability rate. If a fixed value is used to describe the index attributes, the investment ranking of the projects to be built may cause a ranking deviation; at the same time, the indicators in the power grid construction project index system have different dimensions and attributes, so the investment ranking of power grid construction projects is a multi-attribute decision-making problem. .
