Design of integrated managing system for NPP safety based on CIMS and fractal modeling method

In order to improve safely, economy and reliability of NPP (nuclear power plant) and to make the best of human, material and information resources in the NP1 a specific function model developing method for integrated managing system based on CIMS and fractal conception is discussed in this paper Under the guidance of general requirement, the developing process is deepened from integer to local, from macrocosm to microcosm. Furthermore, under the conditions of modularization, high inter-aggregation and low coupling, the developing process has the characteristics of layered detailing of the complexity degree. (authors)
