Abstract
En 中文
In engineering, the widespread uncertainty variables may endanger structural safety. Constructing a model to accurately describe time-variant epistemic uncertainty variables with stationary characters has been a challenge. To address the issue, this paper introduces the concept of a minimum interval radius-based stationary interval process model (MIR-SIPM), whose construction is essentially a constrained optimization problem. Moreover, this paper proposes two methods to eliminate the constraints in the optimization problem corresponding to the construction of MIR-SIPM, presenting two unconstrained optimization problems to construct MIR-SIPM efficiently. Through numerical experiments, the accuracy and efficiency of the proposed methods in describing the uncertainty variables and information are validated.
