摘要工程进度控制及网络优化的研究从出现至今,一直是项目管理的重点研究对象,也是项目成败的关键因素之一,人们对其的研究从未停止过。本文通过对国内学者提出的机动时间稳定性和传递性理论加以分析并总结,提出了机动时间是否对紧后工序产生影响的详细检索步骤,给出了网络中具有机动时间稳定性或传递性工序对紧后工序是否影响的简易判别方法和证明过程。结合算例进行科学的计算,证明了检索步骤的可靠性。同时基于上述影响的存在,对规避影响的方法进行了详细的探究,对费用-工期的各种优化方法的适用环境进行了分析和评价。提出方法的选择要根据项目实际情况而定,不能一概而论。小项目可以选择线性规划法或整数规划法;大项目则选择网络流量法;复杂的大项目则选择遗传算法。56099

abstract
The study of project progress control and network optimization from the appearance to the present, has been the focus of the project management research object, but also one of the key success of the project, people have never stopped their studies. Based on domestic Stability and transitivity of flexible time’s analysis and summary. Raised whether the flexible time impact the later activities’s detail search steps , Presents a simple proof of identification methods and procedures of whether the work in the network which flexible time has Stability or transitivity has impacts on the later activities.With examples of scientific computing, proved the reliability of retrieval step. Based on the presence of these effects,in order to avoid impact, we carried out a detailed inquiry,and we do many analysis and evaluation to the environment of methods to solve the costs - duration.Proposed method chosen according to the actual situation of the project and can not be generalized.Small items can be selected linear programming or integer programming;Large projects can be selected network traffic law;Complex genetic algorithm can be selected large projects.
Keyword:network optimization; flexible time; retrieval step; costs - duration; optimization
