... sensitivity analysis techniques. There are many quantities to describe the FU. The authors attempted to inspect many of the most important ones in two different orientations of the stirrer (horizontal, vertical). Design/methodology/approach Surrogate modelling techniques are involved to compute the Sobol...

.../approach Two novel strategies enhanced by the surrogate model based weighted expected improvement approach are discussed. The algorithms are tested using a two‐variable test function. The emphasis of these strategies is on accurate approximation of the shape of the objective function to accomplish...

... Electric machines Discrete optimization Interval arithmetic Optimal design Deterministic method Global optimization Induction machine Surrogate modelling Techno‐economic model In most practical cases, all problems of optimal design have two common distinctive peculiarities. The first one...

.../methodology/approach This paper discusses the use of kriging surrogate modelling in multiobjective design optimisation in electromagnetics. The investigation relies on the use of special test functions. Findings The importance of achieving appropriate balance between exploration and exploitation...
