Problems solved by technology

Since the premise of this method is to assume that the time of each activity of the project obeys a normal distribution or a β distribution, the total duration and the critical path are random, but with the determination of the critical path, this assumption loses its meaning, so it has a certain defect

Embodiment Construction

[0063] The present invention is further elaborated below by specific example, as figure 1 As shown, the specific steps of the risk assessment method are as follows:

[0064] (1) Establish a risk assessment index system on the power sales side of power grid enterprises

[0065] First, establish a risk assessment method for power grid enterprises on the electricity sales side, combined with the business upgrade under the gradually open environment of the electricity sales side, the present invention adopts three-layer risk assessment indicators, and establishes a model such as image 3 Shown:

[0066] According to the relevant commercial risk system and the actual situation of power grid enterprises, the risk index evaluation system of the present invention is divided into three levels: target layer N, first-level evaluation index layer Ni (i=1, 2, 3, 4), second-level evaluation index Layer N1i (i=1,2,3,4) or N2i (i=1,2,3,4) or N3i (i=1,2,3) or N4i (i=1,2); target layer N Ris...

Abstract

The invention relates to a power grid enterprise electricity-selling side risk assessment method based on a triangular fuzzy number and an improved analytic hierarchy process. The method specifically includes following steps: establishing a power grid enterprise electricity-selling side risk assessment index system; establishing a power grid enterprise electricity-selling side risk assessment index scoring standard; establishing a triangular fuzzy conversion function; establishing an index scoring mapping relation; establishing a determination matrix; determining the matrix consistency verification; returning to the previous step if the consistency is not satisfied; moving to the next step if the consistency is satisfied; calculating a weight coefficient; and determining an important risk factor. According to the method, risk assessment of various risk indexes is conducted through an expert scoring method, the electricity-selling side risk can be comprehensively evaluated, the assessment method is simple and easy to operate, but the subjectivity is relatively high; and the subjectivity of expert scoring can be reduced with the cooperation of a multi-dimensional expert scoring set based on the triangular fuzzy number so that the accuracy of results output by the subsequent analytic hierarchy process is improved.

Description

technical field [0001] The invention relates to a risk assessment method for power sales side business of a power grid enterprise, in particular to a risk assessment method for power sales side of a power grid company based on fuzzy triangular numbers and improved analytic hierarchy process. Background technique [0002] Electric power marketing is the core business of power supply enterprises. The quality of electric power marketing work is related to the existence and development of electric power enterprises themselves. The power demand is multiplied and contradictory. First, electricity consumers hope for low electricity prices, high-quality services, and safe and stable power supply; second, enterprises hope for high investment returns, continuous technological advancement, and greater room for development; third, employees hope for job security and high wages; It is the government's hope that the development of electric power should be compatible with social and econom...
