The Process of Founding a Generic Evidential Model Based on Extending Compatibility Relation
基于扩展相容性关系的通用证据模型建立过程

Evidence modeling has become a bottleneck problem of restricting the application of D-S evidence theory currently. Dempster(1967) firstly brought forward an important concept-compatibility relation based on the research of multi-value mapping. Shafer(1985) defined basic probability assignment function-the model of evidence based on the compatibility relation later. By extending compatibility relation of belief function, the process of founding a generic evidential model is described for kinds of uncertainty in this paper. Compared with Appriou's(1999) first model, the physical meaning of the process of founding the generic evidential model is much more explicit and the system info is much more integrated. This process of modeling has wider range of application than other modeling methods of evidence.
