軟件可靠性的提高
嚴(yán)格進行軟件工程化管理是提高軟件可靠性的必經(jīng)之路。按照軟件工程化要求,需要做好如下五方面工作:
?。?)前期項目組針對軟件進行充分的論證和分析,爭取將軟件需求明確體現(xiàn)在軟件研制任務(wù)書中;
(2)設(shè)計過程中,盡量提高軟件模塊或單元的高內(nèi)聚性、低耦合性。單元之間的接口盡量明晰,整個系統(tǒng)軟件的復(fù)雜度不易過高,該拆分的就需要合理拆分為多個組成部分;
?。?)加強軟件文檔的健全性和準(zhǔn)確性,按照GJB438B-2009《武器系統(tǒng)軟件開發(fā)文檔》的要求,軟件研制過程中的文檔不能有缺失、描述不清、前后矛盾等情況出現(xiàn)。這些文檔必須經(jīng)過專業(yè)人士的評審認可,并且問題回歸后才能進行歸檔;
?。?)逐步建立軟件標(biāo)準(zhǔn)化工作,包括文檔標(biāo)準(zhǔn)化和代碼模塊標(biāo)準(zhǔn)化,這樣可以有利的縮短研制周期,降低研制風(fēng)險,提高軟件產(chǎn)品的重用率;
(5)切實加強嵌入式軟件的測試工作。
