By relaxing cross-member constraints, the model is decomposed into member-wise subproblems, and a nested optimization structure is developed based on the job shop scheduling results.
Collaborative optimization (CO), one of the multidisciplinary design optimization techniques, has been credited with guaranteeing disciplinary autonomy while maintaining interdisciplinary compatibility due to its bi-level optimization structure.
To achieve this goal, a hierarchical indirect optimization structure is often selected.
The structure optimization by the empirical (MM+), semiempirical (PM3), and ab initio (HF/6-21) methods showed that these molecules are energetically stable.
The results of atomic-structure optimization and calculation of the electronic structure of the Si20, Si20-, NaSi20, and KSi20 clusters are reported.
The spectra were interpreted with the aid of normal coordinate analysis following full structure optimization and force field calculations based on density functional theory (DFT) and Hartree-Fock (HF) at 6-31G* and 6-311++G** basis sets.
The work provides useful reference for structure optimization selection of the driving diaphragm of micro valveless pump.
When the structure optimization of the side load spring is performed using FEA software ANSYS, its vertical and lateral elastic characteristics, supported by test data, are analyzed.
