Arrow Diagramming Method (ADM):箭线图 PERT and CPM focuses on float duration, to determine which activities have the least scheduling flexibility.
PERT计划评审技术 Program Evaluation and Review Technique程序评估和回顾技术
Emphasis on meeting schedules with flexibility on cost重点在于成本的计划与弹性相协调
Three time estimates per activity:  pessimistic, most likely, and optimistic每项活动评估三次：悲观的，一般的，乐观的
The probability of completing a project at or later than its expected time is 50%按预计或晚于预计时间完成项目的概率为50%
Event oriented; uses dummy; activity on arrow (AOA)事件为导向的；使用标志符；活动箭头
Finish-to-Start logical relationship结束即开始的逻辑关系
Time estimates appear on arrow时间评估出现在箭头上
Critical Path Method关键路径方法 (CPM) Emphasis on controlling cost and leaving the schedule flexible重点在控制成本上，让计划保持灵活性
One time estimate per activity每项活动评估一次
Activity oriented; uses dummy; activity on arrow活动为导向；使用标志符；活动箭头
Time estimates appear on arrow时间评估出现在箭头上
Precedence Diagram Method优先图方法 (PDM) Represents improvement to PERT and CPM by adding lag relationships to activities 
[Start to Start; Start to Finish; Finish to Start; Finish to Finish]开始对开始；开始对结束；结束对开始；结束对结束
Work is done during activity. Arrow indicates dependancy在活动中完成工作。箭头指示依赖性
Activity on node; no dummy节点上的活动；没有标志符
GERT A network diagram drawing method that allows loops between tasks. It is a method of sequencing (e.g. a project requires redesign after completion of testing) 允许任务之间发生循环的网络图表制图方法。有先后次序的方法（例如：测试完成之后，项目需要重新设计）
Dependencies依赖关系 
Mandatory or Hard强制 Often involve physical or technological limitations (based on the nature of work being done)常常包括了物理及技术上的局限性（基于被完成任务的属性）
Discretionary自由 Soft:  desirable and customary (based on experience)软件：需要的，习惯性的（在经验基础之上）
Preferential:  preferred or mandated by a customer (also, need of the project sponsor)优先：
External外部 Input needed from another project or source从其他项目或资源输入所需 

Resource Planning Tools 资源分配工具
Responsibility Matrix责任矩阵 Identify who does what at what time/phase of the project定义谁在项目的什么时间/阶段做什么
Resource Spreadsheet资源表 Quantifies how much work is needed from each resource during each time period量化每段时间从各个资源所需的任务量
Resource Gantt Chart资源甘特图 Identify the periods of time (e.g. calendar date) when a particular resource is working on a particular task在一个特定的资源用于一个特定任务时，定义时间段（如：日历）
Resource Histogram资源柱状图
(Resource Loading Chart)（资源复合图） Vertical bar chart showing the total number of resources needed during each time period显示在每一个时间段所需资源总量的垂直条状图

Scheduling Tools进度计划编制工具 
Networks  (PERT, CPM, PDM)网络 Interdependencies; how related相互依赖；相互关系的
Barchart  (Gantt)甘特图 Effective progress reporting tool; no logical relationships shown between activities有效的发展报告工具；在活动中不现实逻辑关系
Milestone Chart里程碑图 Significant events; good for communicating status (used to track success)重要事件；对沟通情况有利（用于跟踪成功事件）
