【摘要】 管理信息系统是由多个相互依赖的功能模块综合构成的,由于设计缺陷及功能满足需求增长的不适应性,导致系统不能实现其功能(即为失效)。运用重正化群方法分析了管理信息系统失效的临界条件,即求解各个功能子模块不能实现其功能的临界概率pc,当各个子模块的出错概率<pc时,则整个系统能实现其功能;如出错概率>pc,则系统出现长程相关而失效。更多还原

【Abstract】 Management information system is concluded with many relative function modules,which will fail because of the design shortcoming and non-adaptability between functions and increasing demands. The critical failure condition of management information system is studied based on renormalization group method. That is, the critical failure probability(pc) is studied of the function module. The management information system will work if the failure probability of function module is smaller than pc, on the contrary, which fail because of the remote relative happening between function modules.更多还原
