This study aims to propose an improved affine interval truncation algorithm to restrain interval extension for interval function.
To reduce the occurrence times of related variables in interval function, the processing method of interval operation sequence is proposed.
The interval variable is evenly divided into several subintervals based on correlation analysis of interval variables. The interval function value is modified by the interval truncation method to restrain larger estimation of interval operation results.
Through several uncertain displacement response engineering examples, the effectiveness and applicability of the proposed algorithm are verified by comparing with interval method and optimization algorithm.
