本文就民用飞机的研制中飞机安全性、可靠性、维修性及测试性(以下简称四性)的指标论证过程,给出了一种论证辅助系统的设计方法。该系统可实现对四性指标数据的管理、关联、搜索、自动匹配等,为四性需求指标论证提供实时的在线数据支持,极大提高指标论证的效率。本文分别对四性指标论证辅助系统功能、架构、及实现等方面进行了阐述。为我国民机研制四性领域的指标论证提供了一种新的思路和方法,极大提升了工作效率。
In this paper, the demonstration of aircraft safety, reliability, maintainability and testability (hereinafter referred to as the “four characteristics”) in the process of civil aircraft demonstration is given, and a design method of supporting system is given. The system can realize the management, association, search and automatic matching of the four-character index data, provide real-time online data support for the four-character requirement index demonstration, and greatly improve the efficiency of index demonstration. This article elaborates on the function, structure and implementation of the auxiliary system of the four indicators. It provides a new way of thinking and method for demonstrating the indicators of the four areas in the development of civil aircraft in our country and greatly improves the work efficiency.
