Application of analytic hierarchy process in determining the weight coefficients of diagnostic index system for occupational chronic obstructive pulmonary disease / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To determine the weight coefficients of the diagnostic index system for occupational chronic obstructive pulmonary disease (COPD), and to provide a reference for the determination of diagnostic indices.@*Methods@#The analytic hierarchy process was performed to establish the hierarchical structure of diagnostic indices for occupational COPD, construct a pairwise comparison judgment matrix, and conduct a consistency test on the judgment matrix, in order to determine the weight of each index.@*Results@#The weight coefficients of six first-level indices and 27 second-level indices were determined based on the analytic hierarchy process.All these index weights satisfied the consistency test.@*Conclusion@#The analytic hierarchy process uses expert experience knowledge to set up the index system, then judges the consistency of expert opinions through the consistency test, and effectively combines qualitative analysis with quantitative analysis, which may provide a scientific and feasible idea for establishing the diagnostic index system for COPD caused by occupational irritant chemicals.
