Extensions of fuzzy sets to broader contexts constitute one of the leading areas of research in the context of problems in artificial intelligence. Their aim is to address decision-making problems in the real world whenever obtaining accurate and sufficient data is not a straightforward task. In this way, spherical fuzzy sets were recently introduced as a step beyond to modelize such problems more precisely on the basis of the human nature, thus expanding the space of membership levels, which are defined under imprecise circumstances. The main goal in this study is to apply the spherical fuzzy set version of Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), a well-established multicriteria decision-making approach, in the context of planetary defense. As of the extraction of knowledge from a group of experts in the field of near-Earth asteroids, they rated four deflection technologies of asteroids (kinetic impactor, ion beam deflection, enhanced gravity tractor, and laser ablation) that had been previously assessed by means of the classical theory of fuzzy series. This way, a comparative study was carried out whose most significant results are the kinetic impactor being the most suitable alternative and the spherical fuzzy set version of the TOPSIS approach behaves more sensitively than the TOPSIS procedure for triangular fuzzy sets with regard to the information provided by our group of experts.

通过球面模糊集评估近地小行星偏转技术

将模糊集扩展到更广泛的上下文构成了人工智能问题中研究的主要领域之一。他们的目的是解决在现实世界中决策难题,只要获取准确和足够的数据不是一件容易的事情。以此方式,最近引入了球形模糊集,这是超越该步骤的基础,可以根据人的本性更精确地对此类问题进行建模,从而扩展了在不精确的情况下定义的成员级别的空间。这项研究的主要目的是在行星防御的背景下,应用球面模糊集版本的“通过优先顺序与理想解决方案相近的理想解决方案”(TOPSIS),这是一种公认​​的多准则决策方法。从近地小行星领域的专家小组中提取的知识之后,他们对小行星的四种偏转技术(动力冲击器,离子束偏转,重力引力增强器和激光烧蚀)进行了评估,这些技术先前已通过以下方法进行了评估:模糊级数的经典理论。这样,进行了一项比较研究,其最显着的结果是动力学冲击器是最合适的替代方案,并且对于TOPSIS方法提供的信息,TOPSIS方法的球形模糊集版本比TOPSIS方法更敏感。我们的专家组。和激光烧蚀),之前已通过经典的模糊序列理论对其进行了评估。这样,进行了一项比较研究,其最显着的结果是动力学冲击器是最合适的替代方案,并且对于TOPSIS方法提供的信息,TOPSIS方法的球形模糊集版本比TOPSIS方法更敏感。我们的专家组。和激光烧蚀),之前已通过经典的模糊序列理论对其进行了评估。这样,进行了一项比较研究,其最显着的结果是动力学冲击器是最合适的替代方案,并且对于TOPSIS方法提供的信息,TOPSIS方法的球形模糊集版本比TOPSIS方法更敏感。我们的专家组。
