Improved Artificial Bee Algorithm for Reliability-based Optimization of Truss Structures

Abstract

Introduction: In order to optimize the reliability of the truss structure more effectively, an improved artificial bee colony algorithm based on small interval was proposed and employed to the engineering practice. Method: First, the optimization model based on the reliability was set up. In the model, the bars were treated as design variables, and the total weight was the object function. Then, the comparisons with other methods in solving the truss structure discrete variable optimization demonstrate the feasibility and effectiveness of the improved algorithm. Conclusion: This work provides a new method for the reliability-based optimization of truss structures.
