Multi-granular Modeling And Its Application In RLMIS

With the rapid development of technology, the increase of informatization requirement degree, the increase augment of produce scales of software and the constant change of application requirements, software engineering are developed. Many problems of software design are improved by putting forward many modeling ideas. In this dissertation, five general modeling ideas are introduced briefly:In cognitive science, human apperception,thought information management and apperception information expression disposal are introduced into modeling.For a given object, mathematic model makes out some essential simple supposes based on proper inherent rule to reach an given target, and gets hold of one mathematic structure to explain especial phenomena using proper mathematic tools, then forecasts the future of objects, optimizes decision-making, controls objects and devises products which satisfy certain need.Object Description is that human realize objects by researching attributes and actions of objects and modeling real world by describing attributes and actions.Data Structure researches operation objects and their relationships in non-numerical programming.Data Modeling supports a kind of language and syntax to precisely describe relationships among data entities, and to define data entities and relationships among data entities. The bottom business data can be conserved by this method, and UML is brought forward to modeling.These modeling methods have their advantages and disadvantages respectively. But they are not suitable to devise RLMIS according to present analysis system, because RLMIS has complex relationship, dynamic data and various user demands changed with manage pattern.In 199s, Quotient Space Theory is put forward by Professor Zhang Bo and Zhang Ling. In this theory, a problem is described by triplet(X, T, f). X denotes the...
