“…Every individual evaluated by the original function is called a controlled individual. Similarly, a generation in which all its individuals are evaluated using the original function is called a controlled generation [39,40]. Metamodel management is generally divided into three principal approaches from an evolution control point of view:…”

“…The metamodel quality is based on its ability to correctly classify individuals in the population. However, the approximate classification procedure is an efficient method to control the quality of the metamodel without knowing the exact classification of the complete generation [40]. The approximate classification procedure proposed by Huang et al [39] is composed of several steps classified in the form of an algorithm (Algorithm 1).…”

“…In the second case, it is done by calling the approximate ranking procedure if n k the number of points required to build the metamodel is greater than the number of points T in the training set. This integration of the metamodel in the evolutionary method can take the form of an algorithm named KA-CMA-ES (Algorithm 2) [39,40].…”

The electro-thermomechanical modeling study of the High Electron Mobility Transistor (HEMT) has been presented, all the necessary equations are detailed and coupled. This proposed modeling by the finite element method using the Comsol multiphysics software, allowed to study the multiphysics behaviour of the transistor and to observe the different degradations in the structure of the component. Then, an optimization study is necessary to avoid failures in the transistor. In this work, we have used the Covariance Matrix Adaptation-Evolution Strategy (CMA-ES) method to solve the optimization problem, but it requires a very important computing time. Therefore, we proposed the kriging assisted CMA-ES method (KA-CMA-ES), it is an integration of the kriging metamodel in the CMA-ES method, it allows us to solve the problem of optimization and overcome the constraint of calculation time. All these methods are well detailed in this paper. The coupling of the finite element model developed on Comsol Multiphysics and the KA-CMA-ES method on Matlab software, allowed to optimize the multiphysics behaviour of the transistors. We made a comparison between the results of the numerical simulations of the initial state and the optimal state of the component. It was found that the proposed KA-CMA-ES method is efficient in solving optimization problems.

The complexity challenges of mechatronic systems justify the need of numerical simulation to efficiently assess their reliability. In the case of solder joints in electronic packages, finite element methods (FEM) are commonly used to evaluate their fatigue response under thermal loading. Nevertheless, Experience shows that the prediction quality is always affected by the variability of the design variables. This paper aims to benefit from the statistical power of the R software and the efficiency of the finite element software ANSYS©, to develop a probabilistic approach to predicting the solder joint reliability in Mechatronic Packaging taking into account the uncertainties in material properties. The coupling of the two software proved an effective evaluation of the reliability of the T-CSP using the proposed method.

“…Based on metamodel, Lin [2] proposed an intelligent sampling approach and employed this for the design of a bus body frame. Hamdani [3] used the Kriging model to efficiently solve the expensive mechatronic optimization problem in soldered joints. Metamodel has not only been applied in the updating process, but also in structural optimization [4], uncertainty quantification [5] and damage detection [6], among others.…”

Modal frequencies are often used in structural model updating based on the finite element model, and metamodel technique is often applied to the corresponding optimization process. In this work, the Kriging model is used as the metamodel. Firstly, the influence of different correlation functions of Kriging model is inspected, and then the approximate capability of Kriging model is investigated via inspecting the approximate accuracy of nonlinear functions. Secondly, a model updating procedure is proposed based on the Kriging model, and the samples for constructing Kriging model are generated via the method of Optimal Latin Hypercube. Finally, a typical frame structure is taken as a case study and demonstrates the feasibility and efficiency of the proposed approach. The results show the Kriging model can match the target functions very well, and the finite element model can achieve accurate frequencies and can reliably predict the frequencies after model updating.
