The conceptual model in uml can clearly express the relations among the objects , and can be easily communicated among the engineering personnel . the aim of introducing the logical model is to guarantee the consistency in translating the pattern definition from a conceptual model to a simulation model . adopting xml to describe the simulation model accords with the semi - structurtion characteristic of scenario data , and is also consistent with the object - oriented thought 應用uml構(gòu)建的概念模型既可以清楚地表示組成想定的對象之間的關(guān)系,又便于在工程技術(shù)人員之間交流;增加一個用uml描述的邏輯模型,目的是為了保證在概念模型向仿真模型模式定義的轉(zhuǎn)換過程中的一致性;應用xml來描述想定的仿真模型,既滿足了想定數(shù)據(jù)的半結(jié)構(gòu)化特點,又符合面向?qū)ο蟮乃枷搿?
