摘要
Complementing our previous publications, this paper presents the information schema constructs (ISCs) that underpin the programming of specific system manifestation feature (SMF) orientated information management and composing system models. First, we briefly present (1) the general process of pre-embodiment design with SMFs, (2) the procedures of creating genotypes and phenotypes of SMFs, (3) the specific procedure of instantiation of phenotypes of SMFs, and (4) the procedure of system model management and processing. Then, the chunks of information needed for instantiation of phenotypes of SMFs are discussed, and the ISCs designed for instantiation presented. Afterwards, the information management aspects of system modeling are addressed. Methodologically, system modeling involves (1) placement of phenotypes of SMF in the modeling space, (2) combining them towards the desired architecture and operation, (3) assigning values to the parameters and checking the satisfac- tion of constraints, and (4) storing the system model in the SMFs-based warehouse database. The final objective of the reported research is to develop an SMFs-based toolbox to support modeling of cyber-physical systems (CPSs).
为进一步说明之前的文章,提出了支持面向特定系统表现特征(system manifestation feature,SMFs)的信息管理和构成系统模型编程的信息模式构造(information schema construct,ISCs)。首先,简要介绍了(1)利用SMFs进行具体化设计的一般过程,(2)创建基因型和表型SMFs的步骤,(3)表型SMFs实例化的具体步骤,以及(4)系统模型管理和处理的步骤。接着,讨论了表型SMFs实例化所需的信息块,提出了为实现SMFs实例化而设计的ISCs。然后,讨论了与系统建模相关的信息管理问题。在研究方法上,系统建模包括(1)在模型空间中放置表型SMFs,(2)针对所需架构和操作,组合所放置的表型SMFs,(3)参数赋值以及约束条件符合程度检查,以及(4)在基于SMFs的数据仓中存储系统构建模型。研究的最终目标是开发一个支持信息物理系统(cyber-physical systems,CPSs)建模的基于SMFs的工具箱。
