Template method for multidimensional integrated balancing of property and reliability, maintainability and supportability

Abstract

The invention discloses a template method for multidimensional integrated balancing of property and RMS (reliability, maintainability and supportability), comprising the following steps: (1) sorting a scheme, extracting data, and dividing the data into three classes: property data, RMS data and cost / preparation time data; (2) processing the property data, and obtaining a property index value; (3) converting MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repair) into use availability A0, carrying out standardization processing, and obtaining the standardized use availability A0*; (4) calculating cost equivalent, and standardizing; (5) inquiring the template according to the property index value, the A0* value and the standardized cost equivalent value c*; and (6) according to the value inquired by each scheme, determining the sequence of all schemes. The method can reduce the level of dependency on software, can quickly, conveniently and effectively obtains the scheme priority sequence, and provides support for scheme decisions at different stages in the comprehensive design of the product. The standardized comprehensive balancing step can reduce the faults in the comprehensive balancing and helps a decision maker to improve the decision level and quality.

Description

Technical field [0001] The invention provides a template method for multi-dimensional comprehensive trade-off of performance and reliability maintainability and supportability (Reliability, Maintainability and Supportability, RMS for short), which involves comprehensive trade-off of schemes in different stages of product comprehensive design. According to the different performance, RMS, and cost of each scheme, query the comprehensive trade-off template to provide support for the scheme decision-making at different stages of product comprehensive design. It belongs to the technical field of reliability engineering. Background technique [0002] Performance and RMS comprehensive trade-off decision-making is an important part of the comprehensive design process. It mainly weighs and compares limited design solutions by comprehensively considering performance and RMS characteristics, and determines the pros and cons of them for decision-making reference. It is a typical multi-...

AI Technical Summary

Problems solved by technology

However, the current performance and RMS comprehensive trade-off calculation is relatively complicated. In engineering applications, only the corresponding software can be used to complete the work quickly, and the necessary classification of data is not carried out in the software calculation process, and the same processing method is adopted, which does not conform to reality. , and it is easy to cause errors of missing data

A lot of repetitive work is required for each calculation, which reduces efficiency. In addition, the comprehensive trade-off decision-making process is not clear
