资源受限条件下公路工程进度计划优化方法

针对资源限制条件下的公路工程进度安排问题，讨论了资源分配的优先准则和工作调整步骤，对比分析了优先系数方法和资源调配方法的优化结果，在优先系数计算公式中考虑“工作最早完成时间”参数，对优先系数计算公式进行了改进，以提高模型的适应性；应用“约翰逊-贝尔曼”法则，对新参数的合理性作了进一步论证。分析结果表明，改进后的模型能够更合理地确定发生资源冲突时各项工作的先后顺序，可迅速有效地得到资源限制条件下的最短工期计划。

Optimization method for highway project scheduling under limited resources condition

To resolve the problems in highway project scheduling under limited resources condition, the priority and adjustment principle of resources allocation was studied, The optimization results of resources based on priority coefficient method and resources scheduling method were compared. In priority coefficient method, the earliest finished time should be taken into account to improve the computing formula for developing the adaptability of computing model, This improvement was discussed with the Johnson-Bellman rule. The results show that this method can quickly determine the sequence of working steps, and can quickly achieve the project scheduling with the shortest time under limited resources condition. 3 tabs, 5 figs, 10 refs.
