问题 问答题

试题二(25分) 阅读下述说明,回答问题1至问题4,将解答填入答题纸的对应栏内。 [说明] 某项目进入详细设计阶段后,项目经理为后续活动制定了如图2所示的网络计划图,图中的“△”标志代表开发过程的一个里程碑,此处需进行阶段评审,模块1和模块2都要通过评审后才能开始修复。

项目经理对网络图中的各活动进行了成本估算,估计每人每天耗费的成本为1000元,安排了各活动的人员数量并统计了模块l、模块2的开发和测试活动的工作量(如表2所示),其中阶段评审活动不计入项目组的时间和人力成本预算,如表2所示。

请计算该项目自模块开发起至模块测试全部结束的计划工期。

答案

参考答案:

模块1:开发时间6天;测试3天;修复1天;测试2天;总计12天。 模块2:开发时间8天;测试3天;修复1天;测试2天;总计14天。 因此,关键路径为模块2的开发、修复和测试,该部分工作的计划工期为14天。

解析:

本题考查项目的进度和成本管理等相关理论与应用。考生应结合案例的背景,综合运用理论知识和实践经验回答问题。 这是一道考查项目工期计算的题目。根据表2给出的每项活动的人员安排和所需要的工作量计算出每个活动计划需要的天数,比如模块1开发的活动计划需要工作量是48人天,安排了8人,48/8=6,所以模块1开发的活动计划需要6天完成。类似地,可得到其他活动计划需要完成的天数分别是:模块1测试3天,模块1修复1天,模块1测试2天,模块2开发8天,模块2测试3天,模块2修复1天,模块2测试2天。 从模块开发到模块测试的计划工期为从模块开发到模块测试的关键路径长度,目前有两条路径:一条是模块1开发→模块1测试→模块1修复→模块1测试,长度是6+3+1+2=12,需要12天;另一条是模块2开发→模块2测试→模块2修复→模块2测试,长度是8+3+1+2=14,需要14天。最长的路径即为关键路径,因此自模块开发起至模块测试全部结束的计划工期是14天。

      In my profession as an educator and health care provider, I have worked with numerous children

infected with the virus that causes AIDS.The relationships that I have had with these special kids have

been gifts in my life.They have taught me so manythings, but I have especially learned that great courage

can be found in the smallest of packages.Let me tell you about Tyler.

    Tyler was born infected with HIV: his mother was also infected.From the very beginning of his life, he

was dependent on medications to enable him to survive.When he was five, he had a tube surgically

inserted in a vein in his chest.This tube was connected to a pump, which he carried in a small backpack

on his back. Medications were hooked up to this pump and were continuously supplied through this tube

to his bloodstream.At times, he also needed supplemented oxygen to support his breathing.

     Tyler wasn't willing to give up one single moment of his childhood to this deadly disease.It was not

unusual to find him playing and racing around his backyard, wearing his medicineladen backpack and

dragging his tank of oxygen behind him in his little wagon.All of us who knew Tyler marveled at his pure

joy in being alive and the energy it gave him.Tyler's mom often teased him by telling him that he moved

so fast that she needed to dress him in red.That way, when she peered through the window to check on

him playing in the yard, she could quickly spot him.

     This dreaded disease eventually wore down even the likes of a little dynamo like Tyler.He grew quite

ill and, unfortunately, so did his HIVinfected mother.When it became apparent that he wasn't going to

survive, Tyler's mom talked to him about death.She comforted him by telling Tyler that she was dying

too, and that she would be with him soon in heaven.

     A few days before his death, Tyler beckoned me over to his hospital bed and whispered, "I might die

soon.I'm not scared.When I die, please dress me in red.Mom promised she's coming to heaven, too.I'll

be playing when she gets there, and I want to make sure she can find me."
