The present invention provides a prediction method of the spare part number of the optical transmission devices. The method comprises the steps of using the important machine plates of the devices to construct the reliability models of the devices, and calculating the annual average fault interval time of the devices; dividing the maintenance guarantee areas, selecting the storage sites of the important machine plate spare parts, according to the annular average fault interval time of the devices in the maintenance guarantee areas, respectively calculating the annular average blocking time of the devices in the maintenance guarantee areas, and according to the time redundancy of the annular permission blocking time and the annular average blocking time of the devices, redividing the maintenance guarantee areas until all maintenance guarantee areas satisfy a preset passable rate index; according to the divided maintenance guarantee areas and the configuration situations of the important machine plates of all devices in the areas, determining the basic numbers of the important machine plate spare parts at the selected storage sites; based on a queuing model, determining the supplement amounts of the important machine plate spare parts and the unimportant machine plate spare parts. According to the present invention, the accurate prediction of the spare part number of the optical transmission devices is realized.
Description
technical field [0001] The invention relates to the field of equipment maintenance, in particular to a method for predicting the quantity of spare parts of optical transmission equipment. Background technique [0002] With the continuous improvement of the level of science and technology, all kinds of automation equipment have become an important support for people's production and life, which requires that the equipment must be able to operate safely and reliably. These equipments have the characteristics of long life cycle and high price. When a failure occurs, it is the most convenient and fast maintenance method to replace the damaged part with pre-stored equipment accessories, that is, spare parts, which can greatly shorten the equipment downtime and reduce losses. Therefore, the determination of the number of spare parts is of great significance to the equipment operation and maintenance department, especially for the operation and maintenance of the optical fiber comm...
