固定资源约束下的网络计划进度优化方法研究

Study on Approach to Optimize Network Planning Schedule for Fixed Resources Constraint

网络计划进度优化是工程项目管理的关键性问题之一。当前对于项目进度优化的研究集中于以最小的资源增量,实现既定的优化工期。本文从关键线路的转移方法出发,提出了一类利用网络计划中非关键节点的时差,将其上资源输入压缩节点进行进度优化的算法,并针对这一方法进行了算例说明,结果显示该方法对解决固定资源约束下的进度优化问题有着积极意义。

Network planning schedule optimization is one of the pivotal issues in engineering project management. The current studies on schedule optimization aim at achieving the optimal goals by least additional resources. In this paper, from transferring the critical path, the authors suggest a schedule optimization algorithm through transferring partial resource of un-critical activities to the critical activities. The result of applying the model shows that it is helpful for resolving schedule optimization issue for fixed resources.
