Analytical Framewok of Operation System's Capacity Manangement after Disruption

Unpredictable disruptions have made mangers quite clear that,no matter how safe the design is,the operation systems can not be immune to nature disarsters,operational accident and intentional attacks still.This paper focus on the capacity management after disruption,and presents an analytical framework be of wide adaptiveness and clearity.Some contermeasures are presented also.All of these are pretended to provide an more logical analysis for the capacity management of large-scale operation systems when they were disrupted.
