【正文】 在建立的各種決策系統(tǒng)中，決策技術(shù)是最重要的技術(shù)。（５）系統(tǒng)優(yōu)化階段：診斷所有在系統(tǒng)運行期間出現(xiàn)的問題，優(yōu)化和提高TPP CIPS的系統(tǒng)性能。系統(tǒng)分析,系統(tǒng)設(shè)計和系統(tǒng)實施是TPP CIPS實施的重要階段, 系統(tǒng)維護和系統(tǒng)優(yōu)化在加強操作層和優(yōu)化系統(tǒng)中也是必需的。根據(jù)該分層模型,管理和決策層的功能系統(tǒng)是管理信息系統(tǒng)( MIS),監(jiān)控分析層的功能系統(tǒng)是監(jiān)控信息系統(tǒng)( SIS)。 CIPS的層次模型計算機集成制造系統(tǒng)的結(jié)構(gòu)描述是一個層次模型，它是設(shè)計和實現(xiàn)計算機集成制造系統(tǒng)的基礎(chǔ),大型火電廠的TPP CIPS是一個生產(chǎn)集成自動化系統(tǒng),它給過程控制和監(jiān)控分析管理以優(yōu)先權(quán)。為了提高整體管理水平和運行效率及增強發(fā)電廠的市場競爭，全世界所有著名的管理公司已經(jīng)取得進步，并且在發(fā)電廠經(jīng)營管理的發(fā)展集成化方面有了經(jīng)驗，最新的成果已經(jīng)在一些現(xiàn)代化發(fā)電廠得到應用。t affect safe operation. This system is an important research item now, which is called Supervisory Information System (SIS)To set up an integration model for power plant, especially large size thermal power plant could bring evident economic benefits to power plants. This paper based upon the thorough study of it, will put forward a three dimensional space architecture which is called Computer Integrated Production System for large size thermal power plant (TPPCIPS).2. Hierarchy Model of TPPCIPSHierarchy model is a structure description of CIMS, it is a base of design and realizing CIMS. Large size thermal power plant TPPCIPS is an industrial integration automation system which gives priority to process control and supervisory analysis management. Referring to Purdue Reference Model, this paper puts forward a hierarchy model with five levels and two sustaining systems. See Figure 1. Five level models and their main functions are: Field control level: this level is the base automation level of power plant, which controls the process directly including various measurements, instruments and actuators.Function control level: this level is to control the technological system of each functional group level, such as bustion control system, feed water control system, steam control system etc. in the DCS of main power building.Unit control level: this level is the workshop machine hall control level of power plant, which controls each unit and balance systems of power plant such as DCS of each unit, PLC and SCADA of auxiliary mon systems etc.Supervisory analysis level: this level is the real time supervisory level of whole power plant, which is to realize operation optimization, load distribution, economy analysis, equipment diagnosis, equipment status maintenance and equipment life management etc.Management and decisionmaking level: this level is the management information level of whole power plant, which is to realize business running management, finance management, resources management etc. norealtime management3.
