Method for identifying interactive association relationship between related service requirements of product

Abstract

The invention discloses a method for identifying an interactive association relationship between related service requirements of product. The method comprises the following steps: step 1, establishinga group rough cloud model of the influence degree between the product related service requirements; step 2, determining the numerical value of the influence degree between the related service requirements of the product; and step 3, sorting the related service requirements of the product based on a DEMATEL method. The method has the beneficial effects that each evaluator is allowed to freely givejudgment and evaluation in the form of interval language values; the advantages of a DEMATEL method, a cloud model theory and a rough set theory are combined; the uncertainty of personal evaluation is processed by using a cloud model theory, so that the use defects of a fuzzy set theory can be effectively overcome; the subjective value and the objective value of the influence degree are comprehensively considered, and the influence degree between related service requirements of products can be more comprehensively disclosed.

Description

technical field [0001] The invention relates to a method for product-related service design, demand analysis, identification and calculation of interrelationships among demands. Background technique [0002] Objective fact 1: Related services provided around products are becoming more and more important. [0003] Since the 1990s, as the boundary between tangible products and intangible services has gradually blurred, companies have begun to provide more comprehensive and personalized product-related services centered on customers, and even realize service transformation. Practice results also show that related services provided around products can help effectively improve customer satisfaction, increase customer loyalty, enhance product market competitiveness, achieve business expansion, and ultimately bring sustainable profit growth, etc. [0004] Objective fact 2: There are various requirements for product-related services, but it is impossible for enterprises to meet all...

AI Technical Summary

Problems solved by technology

However, for Type-1 fuzzy sets: it is very contradictory to use an accurate value to measure the fuzziness; for Type-2 fuzzy sets, the value takes into account the fuzziness of the degree of membership, while ignoring the uncertainty of the interval sex

Therefore, both fuzzy sets have their own defects, and they cannot deal with the ambiguity and uncertainty of personal evaluation well (intrapersonal uncertainty)

[0021] (4) Existing studies have shown that people usually prefer to use the form of language value to give judgments, and it is often difficult to express perception with an accurate number
