Evaluation method for manufacturer of collection terminal based on multi-attribute decision-making model

Abstract

The invention discloses an evaluation method of a collection terminal manufacturer based on a multi-attribute decision model, which relates to an evaluation method. The method includes steps of acquiring original data and obtaining an evaluation index; calculating each evaluation index value, constructing the evaluation index matrix and forming the decision matrix; calculate the information entropy of index value and Spearman grade correlation coefficient, determine the objective weight of quality evaluation index, process the decision matrix, and obtain the evaluation matrix of collection terminal equipment supplier; the positive ideal solution and the negative ideal solution of the supplier of the acquisition terminal equipment are calculated, and the Euclidean distance from the supplierof the acquisition terminal equipment to the positive ideal point vector and the negative ideal point vector is calculated. The relative approximation degree between the supplier of each acquisitionterminal equipment and the ideal solution is calculated, and the quality grade of each supplier of acquisition terminal equipment is determined from high to low. The technical scheme provides an objective and scientific basis for the power grid company to carry out the operation and maintenance of the electric power information acquisition system and the quality evaluation and supervision of the acquisition terminal equipment.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an evaluation method for acquisition terminal manufacturers based on a multi-attribute decision-making model. Background technique [0002] With the gradual deepening and application of the construction of the electricity consumption information collection system, collection related resources such as collection terminals, smart meters, collection communication channels, and collection operation and maintenance teams are gradually expanding in the provincial companies. Collection terminals are the core components of the electricity consumption information collection system. , its quality directly affects the success rate of users’ electricity consumption information collection, test call, and remote setting, and further affects the electricity bill settlement of the power supply unit. The operation and maintenance caused by its failure has also been wasted in recent years. A lot of ma...

Problems solved by technology

[0003] Existing methods generally evaluate the operation quality of collection terminals on the basis of some simple assessment indicators, such as collection rate and online rate, and lack the support of various data in actual operation, which is not convincing.

Therefore, the quality evaluation index system of the collection terminal is not comprehensive enough, the evaluation model and method are not perfect enough, there is a lack of scientific and reasonable quantitative evaluation of the quality of the collection terminal, and it is not possible to provide scientific and reasonable evaluation support for marketing measurement and material management.
