A constraints-shifting sequential method for reliability-based design optimization of engineering structures

Reliability-based robust design optimization under hybrid random and interval uncertainties

This paper utilizes the concept of robust design to conduct uncertainty-based design optimization under mixed random and interval uncertainties. Specifically, the reliability-based design optimization (RBDO) framework is used to handle random uncertainty, while the robust counterpart of RBDO is constructed using the mi...

Efficient Material Utilization in Truss Structures Using Deterministic and Metaheuristic approach

When the geometry and connectivity of a truss are fixed, efficient material utilization under strength, serviceability, and stability constraints is addressed as a size optimization problem. This study presents a comparative study of the material minimization of a truss structure by using three optimization algorithms:...

A modified augmented lagrange multiplier method for production scheduling within steelmaking plants

Within the current steelmaking and continuous-casting (SCC) production, the growing differentiation in the production processes stemming from the product diversification, brings about great difficulties in solving the SCC scheduling problem, and decreases pitifully the possibility of ascertaining the duality gap which...

A Heuristic Approach for the Optimization of Maintenance Task Plans in Electric Power Distribution Systems With Resource Constraints

In this study, we present a new approach for the optimized scheduling of maintenance tasks in electric power distribution networks based on a classic optimization technique. The original mixed-integer non-linear programming model is linearized using the piecewise linearization technique, adopting a classical pseudo-dyn...
