By carving up the management levels and expounding the management scales, it deduces that both the flat structure and hierarchicstructure have their advantages and disadvantages.
通过对管理层次的划分和管理宽度的论述，认为扁平结构与直线结构各有利弊。
2
On the other hand, this algorithm has a modular structure and its hierarchic and parallel implementation shortened the control period.
另外，该算法具有模块化结构，它的分层和并行实现缩短了双手的控制周期。
3
According to the structure character of the model, it's adopted by hierarchic optimization strategy.
