工作分解结构(WBS)是工作内容的分层表示。它被证明是有效的,使用WBS的定义和结构工程。WBS现在是项目管理中的一个共同的工具,项目管理知识的书(PMBOK)收集和重新定义它的话。根据PMBOK的描述,WBS是一个可交付成果导向的层次分解的工作将由项目团队执行(PMI,2008)。通过项目WBS,又可细分为更小的部分,为了让项目经理或其他人员对项目要素明确。同时,它可以使操作程序标准化的一大贡献。


在1917年由亨利·劳伦斯·甘特发明的甘特图。甘特图的形式是一种棒图。以棒图,横轴表示的持续时间,而垂直轴代表在项目中的那些任务。在图表中的单杠,给人以视觉上的形象,以飨读者了解每个任务的条件。单杠的长度可以显示的任务应该花多长时间的酒吧的开始和结束的时间点的任务的开始和结束。甘特图是由任务持续时间的关系附件和时间尺度。


3. Overview of Schedule Management Tools


3.1 Work Breakdown Structure (WBS)
Work breakdown structure (WBS) is a hierarchical representation of the work contents. It is proved to be efficient that using WBS to define and structure the project works. WBS for now is a common tool in project management as the Project Management Book of Knowledge (PMBOK) collected the word and redefined it. According PMBOK’s describe, WBS is a deliverable oriented hierarchical decomposition of the work to be executed by the project team (PMI, 2008). Through WBS, the project can be subdivided into smaller parts in order to let project managers or other workers clear about the components of the project. And also, it can make a great contribution to operate procedure standardization.


The importance of Work Breakdown Structure has been acknowledged by both theoretical researchers and engineering practice personnel. First of all, tt is the basis for defining work packages which is the crucial work of project management preparation (Rad, 1999; Colenso, 2000). Garcia-Forniels et al. (2003) declared that the WBS is the most important tool for project management because it provides a basis for scheduling, planning, responsibility assignment, information management and control. Also, through the procedure of WBS, the construction project information can be collected by the computer. Thus the WBS is the fundamental of project informationize.


Being a kind of scientific methodology of project management, the process of decomposition lead by WBS is not arbitrary but according to a sequence of principles and standards. There are 3 most important pre-works need to complete before project managers initiate the WBS process. The first relates to the decomposition criteria, which reflect the facets of information by which the work is subdivided across the WBS hierarchy. The second is the sequencing of these criteria, which relates to the order in which the criteria are applied in the hierarchy. The third issue relates to the level of detail, which reflects the extent to which the entire work is decomposed.
