The application of unascertained measurement model in safety evaluaion of construction

The evaluation of construction's safety is a systematic project involving multi-factor. Accordingly, select the most impact factors on safety evaluation of construction as indicators, establish unascertained measure comprehensive evaluation model. Applications used by the model shows that the evaluation result can objectively reflect construction's safety, which provides a new method and way for safety evaluation of construction and has theoretical and practical value. Due to the ordered division of evaluation space, the unascertained measure model improves distinguish level. It has reliable assessment result and is a practical model.
