Automated Production Of Heterogeneous Industrial Control System Integration

With the aim of guiding the development actions in the distributed Management Information System (MIS) field better, I summarized and obtained some available theory result from real CDMIS projects. The paper focuses on three key techniques: three-tier architecture and components technique, Role Based Access Control technique and workflow system technique. This paper discusses both the basic theories and the realized schemes of all these technology. The workflow system technique is the emphasis of this article.In the chapter about the three-tier architecture and component technique, at first, I introduce the general situation about the developmental history of soft-architecture: from one-tier architecture to C/S model, then three-tier architecture. Secondly, I tell of the organization form, virtues and shortcomings of all these models. At last, I introduce the structure form, peculiarity, and realized scheme and running way of three-tier architecture in detail, I also introduce the relative components technique in brief.In the chapter about the Role Based Access Control technique, at first, I introduce the theoretical model. Secondly, I tell of its realized scheme in CDMIS, include the grounded theory and some main control tables'structure.In the chapter about the workflow system technique, at first, I introduce its keystone. Secondly, I expound two different realized blue prints. One of them is the special system which aims at those long and complex flow processes. This system mainly includes three modules: flow modeling, flow running and flow monitoring. Another system aims at those short and simple flow courses. This system Apply Extended Role Based Access Control technology on short workflow operations, it use role serial number to control workflow operations.
