The Research Of Tollgates Based Avinoic Software Development Lifecycle And Implementation Of Project Review Portal

With the development of China Aviation industry, China has been investing more andmore on self-development aviation products. We are facing an important developmentopportunity of China Aviation industry. At the same time Avionic as one of the most importparts of aviation industry has become the most valuable, rapid development area. Thedevelopment of Avionic requires strict development process and need to meet differentobjectives based on different level. This raises very strict requirement on avionic softwaredevelopment lifecycle.In this article we analyzed the requirements of avionic development processes and theobjectives of the processes in DO-178B. We proposed a tollgate-based software developmentlifecycle and developed a B/S based project review tool based on this lifecycle.We discussed all different phases of the whole lifecycle of the development of theproject review tool, including: Requirement analysis based on use case and user story analysis;Architecture design including database design， system high level design， layers of the system and frameworks we used for different layers; Detail design and implementation:Design patterns we used to implement different layers and the public components we used.Testing including requirement based test and unit test.In this article we provided one practical software and tool categories and tollgate basedsoftware development lifecycle model and developed a useful tool for the project review.This article is a good guidance for DO-178B software development and also helpful tostandardize project review.
