Knowledge Service Technology for Supporting Intelligent Product Design

Abstract

In this paper, a knowledge service method that supports the intelligent design of products is investigated. The proposed method provides the solutions to computational problems and reasoning and decision-making problems in the field of intelligent design. The requirement analysis of a knowledge-based intelligent design system integrates design knowledge into case-based reasoning activities through scheme analysis, scheme evaluation, and scheme adjustment, thus achieving knowledge-based intelligent reasoning and decision-making. During the similarity matching, a new hybrid similarity measurement method is proposed to calculate the similarity of crisp and fuzzy sets. This method integrates the fuzzy set similarity theory based on the traditional similarity measurement method. A method of attribute level classification is proposed to assign weight coefficients. The attributes are divided into the primary matching and auxiliary matching levels according to the decisiveness of case matching, and the set of weight coefficients is continuously and dynamically updated through case-based reasoning learning. Then, the weighted global similarity measure is used to obtain the set of similar cases from the case database. Finally, a design example of a computer numerical control tool holder product is studied to present the practicability and effectiveness of the proposed method.

Commercialising potential as a critical factor of differential media management: a cultural zoning study of China’s regulation of mukbang and online eating disorder communities

“…Eat-streaming research in Chinese, aligning with CCP’s agendas, criticises eat-streaming as (1) negative, vulgar, obscene, and internet trash (Li and Liu, 2019; Lu, 2020; Ma, 2018; Zhao, 2018); (2) unethical, immoral, repetitive, and meaningless (i.e. not facilitating China’s ideological training) (Wang and Chu, 2021; Yao, 2020); and (3) misguiding and encouraging unhealthy consumption (Qu, 2019; Shi, 2019; Wang and Niu, 2021). However, these criticisms tend to be one-sided, missing eat-streaming’s embodiment of the complexity of China’s censorship and its market-oriented governance.…”
