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 present invention provides a reliability model-based electronic equipment spare parts configuration calculation method, including: 1) determining the minimum acceptable value of the optimized spare parts support probability according to the equipment support resources and the requirements of the equipment user; Stress conditions and physical structures determine the basic configuration parameters for spare parts configuration calculation; 2) Analyze the relationship between all the components of this type when the equipment completes the task, analyze the reliability logic relationship between the components of this type, and establish a reliability model, Calculate the total failure rate of this type of component according to the corresponding mathematical model of the reliability model; 3) Construct an iterative model for spare part configuration calculation to obtain the number of spare parts that need to be configured for this component. The invention solves the problem of precise configuration of spare parts, and can effectively and accurately configure the quantity of spare parts in combination with reliability models and reliability prediction data.

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...
