Abstract

The invention relates to a spare part guarantee probability calculation method and device for electronic universal parts, and belongs to the technical field of equipment spare part guarantee. The method comprises the following steps: establishing a probability matrix by utilizing the fault probability of each equipment universal part; selecting equipment for arranging general parts in columns as current equipment in sequence, sequentially calculating probability distribution conditions of the sum of faults of the general parts in other equipment by utilizing convolution operation, and finallycalculating spare part guarantee probability of the current equipment according to the probability distribution conditions of the sum of faults of the general parts in the other equipment. According to the method, the fault probability of the universal part in different devices is fully considered, the guarantee probability of the current device is calculated by using the fault probability of other devices, the overall demand of the universal part is planned, and resource waste is reduced while the sufficiency of spare part resources is met.

Description

technical field

[0001] The invention relates to the technical field of equipment spare parts support, in particular to a method and device for calculating the probability of spare parts support for electronic general-purpose parts. Background technique

[0002] Electronic general-purpose parts are electronic component units that are interchangeable in different types or the same type of equipment with different specifications, such as: printed circuit board plug-ins, resistors, capacitors, integrated circuits, etc. The life law of an electronic component unit is often described by an exponential distribution. The life X obeys the exponential distribution and is denoted as X~Exp(μ), and the density function of X is Due to the high versatility of common parts, after comprehensively considering the overall demand of all equipment (including common parts), centralized storage and unified supply of spare parts resources are often adopted. In the conventional spare parts guarant...
