A hybrid firefly-Bayesian Neural Network approach for survival and reliability estimation in non-homogeneous Poisson processes

open access: yesScientific African
We develop a new parametric inference scheme, which will combine Bayesian Neural Networks (BNNs) and Firefly Algorithm (FFA) in order to estimate the parameters of the Gull-Alpha Power Gompertz-Makeham (GAPL-GM) distribution fitted in a Non-Homogeneous ...

Non-Homogeneous Poisson Process Software Reliability Model and Multi-Criteria Decision for Operating Environment Uncertainty and Dependent Faults

open access: yesApplied Sciences
The importance of software has increased significantly over time, and software failures have become a critical concern. As software systems have diversified in functionality, their structure has become more complex, and the types of failures that can ...

Time-Dependent Reliability Evaluation of Scraper Chain Based on Dependent Competing Failure

open access: yesIEEE Access
During operation, scraper conveyors endure severe and highly complex operating conditions that induce multiple failure modes. These modes are dynamic, interdependent, and competitively interacting.

NHPP 二 モトヅク ソフトウェア シンライド セイチョウ モデル ノ テイリョウテキ ヒカク [PDF]

open access: yes
ソフトウェアのテスト段階から収集したデータに基づいて,ソフトウェアの信頼性を定量的に分析,評価するためのモデルが数多く提案されている.本稿では,学生実験から収集したデータを利用して,非同次ポアソン過程(NHPP)の理論を応用したソフトウェア信頼度成長モデル(SRGM)の比較を行う.先ず,推定値の誤差評価及び信頼度成長曲線の適合度評価に関し,S字型SRGMが指数型SRGMより優れていることを示す.次に,超指数型SRGMに対し,推定精度を高める新しい方法を提案する ...
