This thesis has summarized the emergence and development status quo of workflow , and also has analyzed the advantages of adopting workflow management and the disadvantages of current workflow management . after detailed research , this thesis has summed up the following : after standardization , conclusion and abstraction , the management , business and activities can be expressed by workflow . workflow can be divided into flow and nodes ; flow has few varieties and the structure of flow is constant ; the structure of nodes is limit and unchanged 经深入研究本文认为：组织的管理、业务与活动，经过规范、归纳和抽象分析后可以工作流来表达；工作流又可以分解为“流”和节点，其流的形式变化是很少的，流的结构形式也是不变的，而节点的构成与结构的全集也是有限已知不变的；对流和节点的活动可以分解为若干个不变的处理引擎予以实现，由工作流管理系统激活各种具体的工作流，调用和控制流与节点的相应处理引擎。
In order to provide the reference to creating the meaningful steel structural system industrial building forms integrating the architectural art with the steel structural technologies , the main approaches , which could organically comb1ne space and forms of industry building with the elements of steel structural building system are probed from the layers of the building system the basic structural member and the building detail 该文从结构体系、基本构件与节点细部三个层面，寻找将钢结构建筑技术与工业建筑艺术表现有机结合的基本途径，力求为创作技艺合一的、有意味的钢结构体系工业建筑作品提供借鉴。
