based on wilensky's ant colony foraging model and considers additional nature rules including multispecies, competition and evolution mechanism,promoted antcolonysim model.it carried out simulations based on antcolonysim under different conditions as well as emergent properties including foraging predominance and analyzed competition predominance.

摘 要：在wilensky蚁群觅食模型基础之上，增加了多样性、竞争机制和进化机制，提出了人工蚁群觅食行为仿真模型。通过对该模型的仿真，分析了不同条件下的系统整体涌现属性，包括最短觅食路径、蚁群觅食优势和竞争优势。

With every timber cut, a plan is made by trained foresters to protect the watershed, ensure regeneration, and maintain or increase biodiversity.

In consideration on the complexity and diversity of network fault, formalized study on network fault management was conducted.

针对网络故障的复杂性和多样性，对网络故障管理的形式化描述进行了研究。

The disorder contained can only cause the complexity in the organization, disorder outside organization has the influence to organization complexity, but it cannot cause the organization the complexity, only if it is absorbed and in the organization, can the disorder constitute the complexity; all nature of the complexity is produced because of the disorder in the organization, if there is no the disorder, the organization has no nature such as fortuitousness, randomness, multiplicity and non-linearity, and it is impossible to appear the perturbation, the fluctuation, emerges with phenomenon such as branch, and cannot change suddenly and evolve.

无序只有包含于组织中才能够导致复杂性，组织外的无序对组织的复杂性产生影响，但它不能导致组织的复杂性，只有被组织吸收，成为组织内的无序，才能构成复杂性。复杂性的所有性质都因包含于组织中的无序而产生。没有无序，组织就没有偶然性、随机性、多样性和非线性等性质，就不可能出现扰动、涨落、涌现和分岔等现象，就不能突变和进化。
