摘要: 针对足球比赛中预警值与实际值误差大、 预警误报次数多等问题, 提出了一种基于改进 Copula 模型的足球竞赛风险智能预警方法。 基于模糊综合评价矩阵确定足球竞赛风险指标评价体系, 划分指标等级状态, 选择Copula 函数, 构建改进 Copula 足球竞赛风险智能预警方法, 对足球竞赛风险进行精准判断, 以减少风险损失。 实验结果表明, 该方法的干扰压制维持在 20 dB 以上, 具有较高的抗干扰性, 可有效对干扰进行抑制。 该方法降低了预警值与实际值之间的误差, 减少了预警误报次数, 具有实用性和可行性。

Abstract: A football competition risk intelligent warning method based on an improved Copula model is proposed to address the issues of large errors between warning values and actual values, and multiple false alarms in football matches. Based on the fuzzy comprehensive evaluation matrix, the evaluation system for football competition risk indicators is determined. The indicator level status is classified, the Copula function is selected, and an improved Copula football competition risk intelligent warning method is constructed to accurately judge football competition risks and reduce risk losses. The experimental results show that the interference suppression of this method is high, maintained above 20 dB, and have high anti-interference ability. It can effectively suppress interference. This method also reduces the error between the warning value and the actual value, reduces the number of false alarms in the warning, and verifies the practicality and feasibility of this method.

Key words: football competitions, risk, fuzzy synthesis, evaluation model, early warning methods
