Data were obtained using Excel 2010, SPSS 24.0, and yaahp 10.0 line entry, sorting, and analysis. IAHP method is used to decompose the multi-objective decision problem into several criteria levels and indicators. The weight value of each index is calculated by fuzzy quantization of the qualitative index. Subsequently, the TOPSIS method is used to sort the weight values obtained by IAHP. Through the combination of IAHP and TOPSIS methods, the construction engineering safety evaluation model is constructed based on IAHP-TOPSIS to evaluate the safety measures in construction engineering and prevent safety hazards.
