    Research on intelligent level of the brain of computility network by WANG Chen, ZHAO Peng, TANG Guohua, WANG Xiaohan, YUAN Xiangyang

    Published 2024-08-01
    “…Based on the existing work and demand analysis in the industry, the goal and stage capability of the intelligent evolution of the brain of computility network were studied, and a classification method of the intelligent level of the brain of computility network was put forward, which included detailed steps such as the selection of the evaluation object, the decomposition of the evaluation process, the consideration of the constraint indicators, and a complete set of rules for the evaluation of the intelligent level of the brain of computility network. Finally a concrete application example was given. The proposed method can effectively quantify the specific level of the brain of computility network system, clarify the direction and index of its evolution to the next level, and provide reference for industry intelligent evaluation and system construction.…”
