【摘要】 基于分层赋时着色Petri网,构建了一个能够准确表达资源配置、任务持续时间及信息传递的资源模型,以便有效进行建设工程项目实施阶段的资源管理和优化配置。在建设工程项目实施阶段资源特点分析的基础上,对分层赋时着色Petri网中的非空颜色集合进行定义,并对资源管理中分层建模、资源分配和资源归还基础模型进行了研究,解决了基于分层赋时着色Petri网构建建设工程项目实施阶段资源模型的关键问题。最后,以某工业与民用建筑的实施阶段为例,进行资源管理模型的构建和仿真分析,验证了基于分层赋时着色Petri网构建建设工程项目实施阶段资源管理模型的正确性和有效性。更多还原

【Abstract】 For the implementation stage of a construction project,in order to effectively carrying out the resources management and optimal allocation,this paper proposed a resource model based on hierarchical timed colored Petri nets,which could accurately express the resource allocation,task duration and information transmission.After analyzing the resource characteristics of the implementation stage of the construction project,defined a non-empty color set in hierarchical timed colored Petri nets.And furthermore,it studied the hierarchical modeling of resource management and the basic model of resource allocation and resource return,then solved the key issues of building resource model based on hierarchical timed colored Petri net.At last,based on the above model theory,it built a resource management model on an instance of the implementation stage of an industrial and civil building.Through the simulation result,test and verify the correctness and effectiveness of the model based on hierarchical timed colored Petri net finally.更多还原
