摘要
提出了刻画函数凸性的几个新概念,研究了它们的若干性质,获得了这些新概念之间的蕴含关系,给出了这些新概念在可靠性理论中的几个应用.
In this paper, some new notions related to the convexity of a real function are introduced, and some properties of these new notions are investigated. Applications of the new notions and their new properties in the theory of reliability are discussed as well.
