[0015] Although the above methods can make a certain evaluation of supplier performance, they are highly subjective, and most of them are qualitative evaluations, which are easily influenced by evaluators.
And it cannot be managed according to the actual level of suppliers

Embodiment Construction

[0039] figure 1 As shown, it involves a gray clustering evaluation method based on the triangular whitening weight function of the central point, including the following modeling steps:

[0040] Step 1), set n decision objects i, m clustering indexes j, and s gray classes k, and according to the sample observation value x of decision object i on clustering index j ij Classify decision object i into gray class k; among them, i=1,2,...n; j=1,2,...m; k=1,2,...,s;

[0041] Step 2), set the value range of the clustering index j to [a j ,b j ]. According to the number s of gray classes that need to be divided according to the assessment requirements, determine the turning points of gray class 1 and gray class s respectively Center point of gray class k where k=2,3,...,s-1;

[0042] Step 3), for gray class 1 and gray class s, construct the corresponding lower limit measure whitening weight function and the upper-measure whitening weight function

[0043] Let x be an obser...

Abstract

The invention discloses a grey clustering evaluation method based on a center point triangle whiten weight function. The method comprises the following steps: setting n decision objects I, m clustering indexes j and s grey classes k, and classifying the decision objects I into the grey classes k according to sample observation values xij of the decision objects I about the clustering indexes j. According to the method, a a grey clustering evaluation model based on the center point triangle whiten weight function is adopted for the performance of suppliers, and the suppliers can be classified and clustered for management; for the model, the improvement of a triangle white function is substantially the replacement of an original pure triangle white function with a hybrid white function (comprising a lower limit measure white function, an upper limit measure white function and a triangle white function), and by such improvement, clustering index valuing range widening problem causing puzzle in the application of the grey clustering evaluation model based on the center point triangle white function for more than twenty years is eliminated.

Description

technical field [0001] The invention relates to a gray clustering evaluation method based on a center point triangular whitening weight function. Background technique [0002] At present, with the wide application of information technology and network technology, manufacturing enterprises are increasingly using information technology to track suppliers in terms of price, quality, payment cycle, delivery cycle, service, contract performance, growth, etc. The information makes it possible for the enterprise to conduct a comprehensive performance evaluation of all suppliers. The application of the information system has greatly improved the enterprise's monitoring of the entire supply chain, and at the same time improved the enterprise's evaluation method for suppliers, increased the evaluation methods for suppliers, and helped enterprises to make a better assessment of the actual cooperation situation of suppliers. Provide timely, accurate and objective assessments to achieve...
