| Abstract: | Combing the actual conditions of computer hardware maintenance and on the basis of the reliability and avai-lability theory of equipmentl subsystem,a calculation method of maintenance importance variables which include equipment / subsystem asset salvage value,importance of business and unreliability was analyzed in accordance with the principle of maintenance funding efficiency optimization.Based on this,the mathematical model for evaluating the maintenance requirement of equipment/subsystem was researched and constructed,and then the maintenance decision algorithm was put forward.Finally,combining the instances,the paper proposed the method of maintenance efficiency eva-luation by using reliability theory of computer equipment/subsystem and the availability analysis based on Markov chain,providing certain inspiration for quantitative assessment of computer hardware maintenance. |
