摘　　要：建立了有限时间区间内设备预防性维修策略的非线性优化模型,给出了符合威布尔分布的换辊系统传感器故障率表达函数,并通过历史故障数据进行参数估计。将所有参数代入优化模型,计算了预防性维修的最优周期。同时,模型和方法对现场维修管理和计划的制订提供了决策支持。A nonlinear model with finite interval for preventive maintenance is given in this paper. And a function of sensor＇s failure rate in roll changing system, which is according with Weibull distribution, is also given. The function＇s parameters are estimated based on historical data of failure rate. All the parameters are taken to the optimized model, and the best periods of the preventive maintenance was obtained. At the same time, model and methods supply the decision - making and support to the local servicing management and plan.
