随着航空电子系统的发展，系统的功能、性能和可靠性日益提高，制造成本也随之呈现正相关的变化。本文旨在研究航空电子系统的可靠性指标MTBF对制造成本的影响。基于TruePlanning成本估算系统模型的原理，通过对内部经验公式的巧妙利用，结合某民机无线电通信导航系统的数据，详细介绍建立系统MTBF和制造成本的函数关系式的方法和过程，为系统采购方和制造厂商开展可靠性和经济性权衡分析提供参考。

System functionality, performance and reliability is enhancing with the development of avionics systems. As a result, the manufacture costhas apositive correlation with the higher level of the system. This paper is aimed at studying the relationship of system MTBF and manufacture cost. Based on theprinciple of TruePlanning and the data of navigation system, introduce the methods and procedures of establishing the function relations between MTBF and manufacture cost through the clever use of TruePlanning’s empirical formulas. This will be a reference for the purchaser and the contractors to develop trade-off analysis of reliability and affordability.
