Abstract

In order to improve the accuracy and rationality in calculating the index weights of sluice safety assessment, and to overcome such drawbacks as single weighing manner, strong subjectivity and rough calculation of commonly-used weights calculation method, three-scale analytic hierarchy process is introduced as a subjective weighing method. The method of maximizing deviations based on the improved whitenization weight function is proposed as an objective weighing method. On this basis, a novel combination weighing method which integrates subjective and objective weights is put forward and is applied to the index weights calculation in sluice safety assessment. Engineering examples indicate that this method is reasonably practicable with strong operability, and could effectively make use of the expertise experience and data information to eliminate the interference of subjective factors and uncertain information. It offers a new idea in determining index weights for sluice safety assessment.

Key words
