NHPP软件可靠性模型参数的保序估计

Restrained Estimator of Parameters of Specified NHPP Software Reliability Model

摘要: 许多主要的非齐次泊过程松模型的故障强度都满足顺序约束条件.在顺序约束条件下,本文提出了故障强度的约束极大似然估计(RML),并讨论了其性质.利用故障强度的RML,获得了软件可靠性模型参数的加权最小二乘估计.

Abstract: Failure intensities of most main nonhomogeneous Poisson process (NHPP) models satisfies order constrained condition. This paper presents restrained maximum likelihood estimator (RML) of failure intensity under the condition, discusses some properties of RML. Through RML of failure intensities weighted least square estimation of parameters of NHPP model is obtained.
