为提高扩展有限状态机(EFSM)测试用例生成的效率及效果,提出了一种基于遗传算法的面向多样性EFSM测试用例集生成方法.在优化遗传算法个体编码和操作算子的基础上,引入EFSM测试序列集多样性度量,利用遗传算法,不断增加测试序列集中测试序列间的差异程度.同时在方法中增加测试序列可行性判别机制,以保证最终测试序列均为能产生测试数据的可执行序列.实验结果表明,与未考虑多样性的EFSM测试序列生成方法相比,面向多样性的方法不仅能够生成可执行并满足测试覆盖准则的测试序列集,而且有效减少了测试序列集生成的时间开销,同时缩小了所需最小测试用例集的规模.

目前民用飞机的技术出版物维护活动主要依靠人工进行源数据的影响度分析.该过程由于对人员的业务能力依赖性较强,因此不能保证源数据的维护流程执行具有合理的优先级,容易影响民用飞机的正常使用.基于层次分析法(AHP)的源数据影响度模型在分析技术出版物主要业务流程的基础上,采用综合评价方法,建立影响度评价指标体系并确定权重系数,计算得到源数据的影响度值并进行等级定义,以此作为源数据维护优先级的判断依据.该模型使得源数据的影响度量化和标准化,源数据的影响度分析可以与人员脱离,减少了业务活动中的人工出错.实例分析说明所提出的方法能够合理判断出源数据的更改优先级,并可以和技术出版物编制管理系统结合使用,具有重要的工程应用价值.

按照现代科学观念,要发现宇宙万物的奧秘需要不断地在微观和宏观、物质和精神等领域进行探索,由于宇宙是无限的,且又有新事物不断产生,因此科学探索似乎永远没有尽头。但在中国传统的“气化论”宇宙观下,无论是微观的粒子还是宏观的星系、无论是物质运动还是精神活动,它们在本质上都是“气”的运动,即《周易》中所说的“阴阳之气”或《庄子》所谓的“通天下之一气耳”①。
