This paper presents a novel layout model and floorplanning tool particularly suitable for taking into account user defined layout constraints on specific sets of modules and specific locations. The user defined layout constraints can be the setting of any common topological property associated with a group of specific modules such as the neighboring property for example. Or the use of any topol...

introduction: the appropriate-use optimization of the limited spaces of the iranian hospitals is believed to be a crucial step towards promoting the efficiency of these healthcare centers. the issue determining the optimization patterns of the layout of units has led to a lot of efforts by researchers as it increases the efficiency of the hospitals through patients’ improvement, changing the lo...

The conventional structural layout optimization method is usually used to solve the problem of a single structure, but it difficult apply modular aircraft structure containing multiple substructures. Therefore, this paper proposes mean value-based parallel collaborative (MVPM) for layout. This two-stage based on decomposition. basic idea MVPM decomposing into system coordination and several ind...

Recently, an improved (l + k) constrainted differential evolution (ICDE) has been proposed and proven to be robust and effective for solving constrainted optimization problems. However, so far, the ICDE has been developed mainly for continuous design variables, and hence it becomes inappropriate for solving layout truss optimization problems which contain both discrete and continuous variables....

natural frequency is one of the parameters that represent useful information about the dynamic behavior of structures. controlling this parameter can decrease the probability of damage under dynamic loading. weight optimization on layout and sizing with frequency constraints is a well known problem because of its highly non-linear behavior. improved ray optimization (iro) algorithm is utilized ...

This paper proposes an optimization methodology of on-chip spiral inductors. Characteristics of spiral inductors heavily depend on layout structures. We then formulate the characteristics with structural parameters and frequency as variables using a response surface method. The proposed method uses S-parameters to express inductor characteristics, and hence our method is independent of spiral g...
