Firstly  we build the SD model of soybean industry. Secondly  we optimize soybean security policy simulation dynamic model and simulate the model based on our country specific situation. At last  on the basis of the simulation results  we analyze current domestic soybean industry security situation and provide a method to make suggestions for soybean security policy. 2012 Chinese Assoc of Automati.   基于访问控制空间的多策略安全体系结构 期刊论文  OAI收割 通信学报, 2006, 卷号: 27, 期号: 2, 页码: 107 李丽萍; 卿斯汉; 贺也平; 沈晴霓   |  收藏  |  浏览/下载：19/0  |  提交时间：2010/08/23 安全体系结构  安全策略模型  Linux安全模块  策略规范 security architecture  security policy model  Linux security module  policy specification
