system of decentralization
1.Based on the development of the control structure of manufacturing system, the advanced manufacturing system pattern with the characteristics of decentralization, integration and intelligentization is put forward, then the paper proposes to establish the agile manufacturing system of shopfloor level, the advanced management and control system(AMCS), and the architecture and the function model of AMCS are also presented.
2.A constitution based system of power decentralization is implemented for education in the United States, which has boosted the diversification of education in the United States.
3.With a briefly introduction of the problems existing in the low voltage distribution system of Guangzhou Metro Line 1, such as indirection wiring, interference of combined piping and wiring, confused standard classification of load level, decentralization of low load power supply, inflexible control mode, etc., the author argues that in the new design of low voltage distribution a great attention shall be paid to the above mentioned problems and a careful comparison between the old solution and the new one shall be made.
4.In combination with the design and application of the distributed control systems (DCS) for 6×300 MW units in Phase Ⅰ～Ⅲ projects of Shenzhen Mawan General Power Plant, a comparison among INFI-90, PROCONTROL-P and XDPS-400 DCS is made in terms of their system hardware, software, degree of decentralization, reliability and integration.
5.It has carried out the reform of rural relations of production, including implementation of the policy of the household contract responsibility system with remuneration linked to output and the two-layer management system featuring the integration of centralization and decentralization. In addition, the scope of market readjustment for grain has been expanded and the price of grain adjusted rationally so as to mobilize the enthusiasm of the farmers for grain production.
7.Aiming at some questions of structure complexity, position decentralization, management means lag for power distribution grid, with interface techniques of GPRS, Modem, RS -232/485, and combining fieldbus control theory, a intelligent distributed monitor system for low voltage power distribution was developed.
8.Since 1991, one of the important reforms of Indian economic system is the decentralization reform under the federalism, by which Indian federalism is to be changed from the cooperative federalism to the competitive one step by step.
9.Decentralization: the more autonomous the modules, the higher the likelihood that a simple change will affect just one module, or a small number of modules, rather than triggering off a chain reaction of changes over the whole system.
10.Auxiliary system FCS based on the two fieldbus was designed and has been successfully applied in BALCO Power Plant in India. Integration at control level is realized via network,in addition,decentralization of control as well as centralized monitoring and operation can be obtained by the field intelligent device and controllers.
