网络计划图优化方法研究

Research on optimization method of network plan chart

通过绘制网络计划图、计算时间参数并指出关键线路,可以形成一个初始的网络计划方案,但一般会存在一些有待解决的矛盾与缺点。因此在满足既定约束条件下,为了设计一个工期短、质量好、成本低以及资源利用率高的计划方案,有必要对初始方案进行调整和修正。文章通过对网络计划图的工期调整、工期优化、资源优化、工期-费用优化等方面进行研究分析,提出可用于优化网络计划图的思路与方法。

By drawing the network plan diagram,calculating the time parameters and pointing out the key lines,an initial network plan scheme can be formed,but there are some contradictions and shortcomings to be solved in general.Therefore,in order to design a plan with short duration,good quality,low cost and high resource utilization,it is necessary to adjust and revise the initial scheme under the established constraints.Based on the research and analysis of the network schedule adjustment,optimization,resource optimization and time-cost optimization,this paper puts forward the general ideas and methods that can be used to optimize the network schedule.
