查询词典 cluster sampling

According to the system view ofdegradation and decomposition put forward above,the paper proposes a newSplit Reasoning Simulation for qualitative model algorithm called SRSQM,which implements the decomposing,reasoning and solving of qualitative models.In another word,it combines variable cluster and causality graph to decompose acomplex qualitative model into many componentsand constraintsamong those components.Through the qualitative reasoning of the componentsand globally propagating the results,the overall solutions can be achieved.

根据复杂系统的递阶分解的系统观点，本文提出一种新的定性模型分解推理仿真算法，称作SRSQM，实现对定性模型的分解推理求解，即对于一个复杂的定性决策模型，应用变量聚类和因果图相结合的方法，将复杂的定性模型分解成若干个单元及其单元之间的约束，通过对各个单元的定性推理以及将单元推理的结果进行全局传播和过滤，得到整个系统的全局解。

After analyzing the basic information of the ecological engineering construction, the spatial and temporal scale, and monitoring index, the 1m IKONOS image and 2.5m SPOT5 image were introdueced as data sources, the methodology of RPC modeling and GCP optimitiaztion as modification to the interpretation, the AHP used in determining combination of multi-light specrum and the whole band wave, the virtue reality technique monitoring the classification and recognation, variable cluster allocation coeffiecents and its adaptation in spatial and imaged attributs in the research on water and siol conservation subtracting the least pathches of the area. The final stage is to subtract the information via human and computer interactive to interpret and monitor the classification in the study assisted with GPS, field identification and construction supervision.
