What is it about?

This study integrated the analytic network process (ANP) and fuzzy set (FS)to develop a construction quality index (CQI) model as a concrete indicator and objective standard for evaluating construction quality.

Why is it important?

The CQI model is based on the frequency of defects and weights, improves the problem of intuitive on-site ratings provided by auditors, and establishes an objective and simple method for rating construction quality to effectively enhance rating standards for construction inspections.


This study proposed a CQI model that integrates the ANP and FS. The advantage of this model is that it can process situations where factors are dependent and extract characteristics of the frequency of defects from historical inspection data as objective ratings from pairwise comparisons. Subsequently, based on the CQI values calculated by each factor weight, the model can more accurately represent actual construction quality than can the construction inspection system.
