Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0036] The cost of spare parts occupies a large proportion of the cost of the entire equipment life cycle. Therefore, the rational planning and allocation of spare parts has always been a hot spot in the research of precise support, and the core issue of spare parts planning and design is the calculation of the required quantity of spare parts. The invention solves the problem of precise allocation of spare parts at the grassroots level, and combines the reliability model and reliability prediction...

Abstract

The invention provides an electronic equipment spare part configuration and calculation method based on a reliability model. The method comprises the steps that (1) according to the condition of equipment support resources and the requirement of an equipment user, the minimum acceptance value of the optimized spare part supportability probability is determined, and basic configuration parameters of spare part configuration and calculation are determined according to the work stress condition and the physical structure of the equipment; (2) the mutual relation of all mold components is analyzed when the equipment completes a task, the reliability logic relation of the mold components is analyzed, the reliability model is built, and the total failure rate of the mold components is calculated according to a mathematical model corresponding to the reliability model; (3) an iteration model of the spare part configuration and calculation is constructed, and the number of spare parts, needing to be configured, of a component is obtained. Precision of spare part configuration is achieved, the reliability model and reliability predicted data are combined, and the number of the spare parts can be configured effectively and precisely. 0.

Description

technical field [0001] The invention relates to a spare part configuration calculation method for electronic equipment. The cost of spare parts occupies a large proportion of the cost of the entire equipment life cycle. Therefore, the rational planning and allocation of spare parts has always been a hot spot in the research of precise support, and the core issue of spare parts planning and design is the calculation of the required quantity of spare parts. Background technique [0002] Whether a certain type of component in the equipment is configured on site or not and the quantity of configuration is determined is called the configuration method of spare parts. Spare parts support probability, that is, the probability that there will be no missing parts when a certain part of the equipment fails and needs to be replaced within the specified guarantee time. As the probability of spare parts guarantee increases, the probability of on-site maintenance without missing parts al...
