Comments for ‘System availability assessment using stochastic models’

Comments for ‘System availability assessment using stochastic models’ I am very honored and delighted to be a discussant for the paper ‘System availability assessment using stochastic models’ by Kishor S. Trivedi, Dong Seong Kim, and Rahul Ghosh. I enjoyed reading this discussion article, because it involves some case studies in computer‐based system engineering with availability assessment. It can be emphasized that the underlying problems are all real‐world examples and are not artificial toy problems as seen in many theoretical papers. From theoretical view points, this paper treats an asymptotic one‐unit system for more complex systems in Figure 3 and shows how to derive transition rates λ eq and μ eq in Equations (4)–(7). However, I have some doubts of such formulations. To compute λ eq and μ eq from equations c1 λ eq = 1 π U ∑ R π i q ij and μ eq = 1 π D ∑ R π i q ij , we need to know π U and π D . However, if we could know π U and π D , the steady‐state availability and its corresponding unavailability can be easily given by A = π U and A ¯ ≡ 1 − A = π D .

Abstract

I am very honored and delighted to be a discussant for the paper ‘System availability assessment using stochastic models’ by Kishor S. Trivedi, Dong Seong Kim, and Rahul Ghosh. I enjoyed reading this discussion article, because it involves some case studies in computer‐based system engineering with availability assessment. It can be emphasized that the underlying problems are all real‐world examples and are not artificial toy problems as seen in many theoretical papers. From theoretical view points, this paper treats an asymptotic one‐unit system for more complex systems in Figure 3 and shows how to derive transition rates λ eq and μ eq in Equations (4)–(7). However, I have some doubts of such formulations. To compute λ eq and μ eq from equations c1 λ eq = 1 π U ∑ R π i q ij and μ eq = 1 π D ∑ R π i q ij , we need to know π U and π D .
