如果T = （t1，···，Tn）是一个随机寿命向量，那么它的分布可以由一组λ的多变量条件风险率决定。本文找到了λ上T为Block-Savits MIFRA（多元递增故障率平均值）或Savits MIFR（多元递增故障率平均值）的充分条件。给出了Ross多变量可靠性模型和负荷分担模型的应用。讨论了多元不完全修复的Shaked和Shanthikumar模型与MIFRA性质的关系。
If T = (T 1, · ··, Tn ) is a vector of random lifetimes then its distribution can be determined by a set λof multivariate conditional hazard rates. In this paper, sufficient conditions on λare found which imply that T is Block–Savits MIFRA (multivariate increasing failure rate average) or Savits MIFR (multivariate increasing failure rate). Applications for a multivariate reliability model of Ross and for load-sharing models are given. The relationship between Shaked and Shanthikumar model of multivariate imperfect repair and the MIFRA property is also discussed.
