查询词典 formal model

First, the formal representation of the search environment is established, the multi-UAV is modeled as a controlled system and the predictive model of the system is presented. Considering the uncertainty of the sensor measurement and the environment, a Search Probability Map is defined and the updating method based on Bayes formula is presented. Based on SPM, information gain is defined to measure the search effects and used to be the optimization object in the predictive horizon. By using of GA, the solution of the optimization problem is got and it is taken as the input of the controlled system.

首先，建立搜索环境的规则描述，然后将多个UAV建模为一个控制系统，建立系统的预测模型，考虑到UAV传感器测量的不确定性和环境自身的不确定性，建立搜索概率图描述搜索环境的不确定性，给出了基于Bayes准则的搜索概率图更新方法，继而基于搜索概率图定义信息增益来衡量搜索效果，并将预测周期内的优化目标定为最大化信息增益，采用遗传算法进行求解，得到最优解作为被控系统的输入。

To regulate policy composition and guarantee its correctness, an algebraic model called APoCA (attribute-based access control policy composition algebra) is proposed for composing access control policy. In APoCA, an authorization relation between entities is described at the attribute level. APoCA fertilizes the existing formal frameworks by taking into account the computation of attribute values.
