A Quantitative Analysis System and Method for Depot Level Maintenance Items Based on Increment

Abstract

The invention discloses a base-level maintenance quantitative analysis system and method based on increment. The system includes: product structure hierarchy and importance division module, calculation of product maintenance frequency and failure rate increment module, calculation of base-level maintenance capacity increment module, determination of base-level maintenance project module and incremental maintenance depth and cost tradeoff analysis module. The quantitative analysis method of the invention establishes a base-level maintenance capability incremental model taking the maintenance frequency incremental strength and importance as quantitative parameters; integrating the product hierarchy, importance, maintenance times, failure rate, maintenance depth and other important use of data and design information, integrated optimization of the above factors to determine the impact of base-level maintenance projects.

Description

technical field [0001] The present invention relates to a method for quantitative analysis of maintenance items, and more particularly, to a system and method for quantitative analysis of base-level maintenance items based on increments. Background technique [0002] After the product is delivered to the user (usually an organization or institution), the user usually needs to establish its own maintenance capabilities. On the one hand, the product can perform rapid and timely self-protection without relying on the product supplier when it is used in an emergency; By increasing the depth of maintenance, the product can be repaired economically, the utilization rate of maintenance equipment can be improved, and the consumption of spare parts for high-level products can be reduced. [0003] Users and suppliers usually determine user maintenance capabilities according to GJB 2961-1997 "Repair Level Analysis". This method conducts qualitative analysis on product safety, confident...

Problems solved by technology

The primary consideration of this method is the economics of establishing base-level maintenance capabilities. Qualitative analysis factors are limited, so most of the needs of users for forming their own core maintenance capabilities are ignored. Some important products and products with high failure rates are often not included in user maintenance. The scope of capabilities can only rely on product suppliers. The result is that the failure of important products will make the entire product unusable, and the cumulative delay time of products with high failure rates will be greatly extended. In general, the normal use of the product is not guaranteed, but the cost is also higher. Practice shows that spare parts and maintenance equipment are the main maintenance resources, and their cost is the most important cost of maintenance capacity building. This method calculates the cost of all resources, but it does not link with the maintenance depth, and does not fully consider the impact of maintenance depth on Impact of repair costs and user demand for high repair depth
