第1题：
Developing the project schedule is often an iterative process. It determines the planned start and finish dates for project activities and milestones. Schedule development can require the review and revision of duration estimates and resource estimates to create an approved project schedule that can serve as a baseline to(75) progress.
A．analyze
B．track
C．level
D．extend
解析：通常，制订项目进度计划是一个反复迭代的过程，该过程确定每个活动和每个里程碑的开工日期和完成日期。制订进度过程要求对历时估算和资源估算进行评审和修订，从而产生一个经过认可的项目进度表，作为对项目进展进行追踪的基准。
第2题：
● Many useful tools and techniques are used in developing schedule． (72) is a schedule network analysis technique that modifies the project schedule to account for limited resource．
（72）
A．PERT
B．Resource levelling
C．Schedule compression
D．Critical chain method
试题（72）分析
在制定项目进度计划中有很多有用的方法和工具。如下：
PERT方法能协调整个计划的各道工序，通过描绘出项目包含的各种活动的先后次序，标明每项活动的时间或相关的成本，合理安排人力、物力、时间、资金，加速计划的完成；
Schedule compression进度压缩，是通过赶工、快速跟进等方法压缩工期，是在不改变项目范围条件下缩短项目进度的途径；
Critical chain method关键路径法计算所有计划活动理论上的最早开始与完成时间、最迟开始与完成时间，寻找活动的关键路径，通过调整关键路径进行进度制定；
Resource levelling资源平衡是根据有限资源调整项目进度的方法。
所以选D。

第4题：
is a method of constructing a project schedule network diagram that uses boxes or rectangles, referred to as nodes, to represent activities and connects them with arrows that show the dependencies.This method includes following types of dependencies or precedence relationships:(67), the initiation of the successor activity, depends upon the completion of the predecessor activity.(68), the initiation of the successor activity, depends upon the initiation of the predecessor activity.
A．PDM
B．CPM
C．PERT
D．AOA
解析：PDM是以一种方块或矩形(或称为节点)来表示活动，并将它们用表示依存关系的箭线连接起来，以构建项目进度网络图的方法。这种方法包括了下列依存或前导关系：完成—开始(F-S)，后续活动的开始依赖于前置活动的完成。开始-开始(S-S)，后续活动的开始依赖于前置活动的启动。

第9题：
(b) Describe a framework to assess the risks to the progress of the Giant Dam Project. Your answer should
include a diagram to represent the framework. (6 marks)
(b) Framework for assessing risk
Risk is assessed by considering each identified risk in terms of two variables:
– its hazard (or consequences or impact) and,
– its probability of happening (or being realised or ‘crystallising’).
The most material risks are those identified as having high impact/hazard and the highest probability of happening. Risks
with low hazard and low probability will have low priority whilst between these two extremes are situations where judgement
is required on how to manage the risk.
In practice, it is difficult to measure both variables with any degree of certainty and so if is often sufficient to consider each
in terms of relative crude metrics such as ‘high/medium/low’ or even ‘high/low’. The framework can be represented as a ‘map’
of two intersecting continuums with each variable being plotted along a continuum.
