摘要
针对以往提出的施工顺序知识表述模式在描述并行时间逻辑方面能力较弱的问题,提出了构件施工状态的概念及14种用来描述构件施工状态间时间关系的区间到区间的时间逻辑,其不仅可以描述施工活动在时间上的前后逻辑,还可以描述并行逻辑.在此基础上,提出了针对单个构件的"状态链"和针对2个构件间的"状态相互作用"的施工顺序规则,并以Express语言描述了两种顺序知识,使它们能够与工业基础类标准兼容,并可以直接嵌入到符合工业基础类标准的建筑设计模型中,使得从建筑设计模型中导出施工顺序成为可能.
Automatic generation of construction sequence from CAD model is a prerequisite for evaluating constructability of capital projects.Unfortunately,traditional studies for deriving construction sequence can not adequately capture or incorporate some necessary concurrency relationships.This paper proposed a new concept of construction state,and uses 14 types of interval-to-interval temporal relationships,resulting in that both precedence and concurrency relationships can be semantically depicted.Moreover,this paper further developed two types of construction sequencing knowledge: state chain type for a single building component and state interaction type for two components.Both knowledge types,which can be represented using Express language,are compatible with the IFC standard,and can also be embedded into IFC-CAD model.
