Abstract：The negative exponential distribution model is used to construct failure interval time of meteorological equipment,and the equipment maintenance time obeys the normal distribution.When more than one devices go out of action,Matlab can record the actual maintenance time of each equipment.The average equipment maintenance time and maintenance efficiency are obtained under the condition of frequently-occurring failures according to multi-simulations,which have a practical guidelines for improving the quality of equipment maintenance and failure reducing.
