With the advance of centralized fault management project

the plan of artificial cooperation emerged and developed rapidly to deal with the demands that telephone connection rate

quality of service.At the same time

the duty configuration problem of fault pretreatment platform began.The purpose of this paper is to analyze the characteristics of fault handling process of failure pretreatment platform with the knowledge of queuing theory

and establish the system model

M/M/C/∞/∞/FIFO

determine the parameters and performance indicators.With the statistics of call details

it is analyzed by this system model that the work condition of the fault handling duty

optimized the number of the duty

and obtained the reasonable allocation method and basis of the duty.
