●设某工厂有B1和B2两条流水线生产同一种产品,B1和B2的产量分别占60%和40%,且B1和B2的不合格率分别为1%和2%。现在从该厂的这种产品中随机抽取一件,结果为不合格产品,则该不合格产品是流水线B2所生产的概率为__(61)__。

●在业务领域分析过程中,通过建立实体关系图,把与业务相关的数据模型化;通过建立__(62)__来表示业务活动的分解过程;两个业务过程之间的相互依赖关系应记录在过程依赖图中;通过建立__(63)__来详细说明整个业务过程的逻辑。

●多个软件工程师合作开发一个项目,各开发者之间需要两两互相通信。假设每一条通信路径的开销为200LOC/年(LOC为代码行数)。设有四名软件工程师,如果单独工作,每个人的生产率是6000LOC/年,那么由这四名软件工程师组成的项目组的生产率为__(64)__。在这一年期限的最后两个月,又增加了四名工程师,新增成员的个人生产率为3000LOC/年,那么这六人组成的项目组全年完成的开发工作量为__(65)__。
(64)A.28000LOC/年 B.24000LOC/年 C.22800LOC/年 D.21500LOC/年
(65)A.21000LOC B.23000LOC C.23500LOC D.24500LOC
●Developing reliable software on time and within __(66)__ represents a difficult endeavor for many organizations.
Usually business solutions have three main aspects : people, __(67)__ , and technology. The main reason for failing software projects has little to do with technology and tools, and much to do with lack of process __(68)__ . Experience has shown that introducing new technology and tools in an immature or undisciplined environment is likely to increase the Chaos.CASE tools are not enough. "A fool with a tool is still a fool!"
Structured method was the first wave of the software industry. This was the beginning of
transforming software development from a "__(69)__ industry" to mass production. Software
process movement is the second wave in the software industry. The process maturity movement
prepares the way for the third wave of the software industry: "software industrialization".
Software development will become like an assembly and manufacturing process. A critical enabling factor is a disciplined software engineering process with predictable quality, __(70)__ and functionality.
