摘 要:全过程动态仿真技术将网络计划分析和数值仿真技术融于一体,以CPM网络模型为框架,再以框架中的仿真节点调用CYCLONE 模型,形成一个分层次的模型结构. 利用CYCLONE 模型仿真工序的随机施工工期和资源利用率等情况,采用CPM网络层对整个工程项目的进度进行分析. 其中CPM网络层模型是面向用户的,而CYCLONE模型属于底层,隐藏在CPM网络层之下,只向CPM网络层提供接口,从而解决了CPM不适合处理具有循环特征的复杂工程和CYCLONE 技术过于专业的问题,取长补短,达到方便和实用的目的. 通过在实际工程中的应用,验证了该技术的可行性.
Abstract : Integrating project scheduling technique with digital simulation technique , the dynamic simulation technique for whole construction processes takes critical path method(CPM) network model as a frame and then calls complex cyclic operation network (CYCLONE) model for its simulation nodes , engendering a hierarchical model . CYCLONE simulation model takes charge of simulating stochastic duration of activity and efficiency of resources , while CPMmodel performs project scheduling. The CPM model is user2oriented and CYCLONE model is wrapped up in the CPM model , which connects CPM model node by interface. In this way the dynamic simulation technique can take the advantage of CPM and CYCLONE as well as avoid their shortcomings , namely , CPMis unsuitable for complex projects with circulating processes and CYCLONE is too professional to be understood. By applying to practical project , feasibility of the technique is verified.
