On the base of the concept of the dependability and combining the characters of electronic information system,it not only puts forward the definition of the dependability of electronic information system and its formal description,but also portrays concept model and evaluation model of the dependability of electronic information system.Through analyzing the factors related with the dependability,the indicators of dependability is established by AHP.Based on the synthesis the current primary methods of system evaluation,the multilayer synthesis evaluation method of the dependability of electronic information system based on entropy weight,is put forward which was used to evaluate the dependability of a system to prove that the method is effective.
