在真实的建筑世界中，用于建筑活动的资源是有限的。为了避免施工现场的资源浪费和短缺，调度必须包括资源分配。本文提出了一种新的资源约束的施工进度计划系统。系统采用了基于遗传算法的搜索技术。本文提出了新的遗传算法交叉和变异算子UX3和UM3。这些新算子克服了传统遗传算法在排序问题中的缺陷。该系统可以有效地在有限资源的约束下提供施工工期、资源量和最短工期的最佳组合。
Resources for construction activities are limited in the real construction world. To avoid waste and shortage of resources on a construction jobsite, scheduling must include resource allocation. A new resourceconstrained construction scheduling system is proposed in this paper. A GA-based searching technique is adopted in the system. In this paper, new GA crossover and mutation operators, UX3 and UM3, are presented. These new operators overcome the drawback of traditional GA operators for sequencing problems. The system effectively can provide the optimal combination of construction duration, resource quantities and minimum project duration under the constraint of limited resources.
