Reliability of Ideal Indexes

open access: yes, 2022
The Fisher and GEKS are celebrated as ideal bilateral and multilateral indexes due to their superior axiomatic and econ-theoretic properties. The Fisher index is the main index used for constructing CPI by statistical agencies and the GEKS is the index used for compiling PPPs in World Bank's International Comparison Program (ICP).

Load and resistance factors for prestressed concrete girder bridges

open access: yesBudownictwo i Architektura, 2020
There has been a considerable progress in the reliability-based code development procedures. The load and resistance factors in the AASHTO bridge design code were determined using the statistical parameters from the 1970's  and early 1980’s.

A method to take account of inhomogeneity in mechanical component reliability calculations [PDF]

open access: yes, 2005
YesThis paper proposes a method by which material inhomogeneity may be taken into account in a reliability calculation. The method employs Monte-Carlo simulation; and introduces a material strength index, and a standard deviation of material strength to ...
