عنوان مقاله [English]
Equipment is usually damaged by a random pattern based on a gradual deterioration process. In these cases, the level of deterioration gradually increases, and when its value exceeds the predefined decline threshold, it is considered disabled. In addition, environmental disturbance factors such as temperature, humidity, pressure, etc. may experience uncontrollable changes and alter or accelerate failure patterns. Since estimating the remaining equipment life is very important in the effectiveness of forecast maintenance planning and this estimate should be based on identifying accelerated failure patterns, the present study is the first to estimate the remaining equipment life in the presence of effects. The accelerator is focused on two correlated disturbance factors and in it to monitor the environmental factors affecting the life of the equipment from control charts and how to meet the average residual life of the equipment in different conditions under control, out of control due to the first disturbance factor, Being out of control due to the second factor and being out of control due to both factors are presented. A numerical example is also provided to illustrate the details of the calculations.
