Scheduling Construction Projects by Using Product Models and Learning from Cases

为了利用许多建设项目计划和 工作方法选择根据以往的经验，一个调度 提出了一种基于实例推理的模型。 该模型不 只适应以前的情况，以适应新的项目， 计划;它还提取和汇总计划知识 并将其作为知识库的一部分 以备将来使用。 因此，在保存时出现的存储问题 许多情况下，周围是减少，因为规划知识是 增量编译。 为了有效地检索这些汇编的知识或案例， CasePlan使用一个产品模型， 项目中存在哪些设计元素以及它们如何 在结构上或功能上与另一个相关。 产品型号 用于案例分类和学习规划知识。 研究表明，产品模型在 组织和编辑知识。 CasePlan系统 这项研究的结果也将是最先进的 自动化施工调度 其时间表将 有足够的细节来驱动离散事件模拟， 该项目的施工执行，可以提供 执行反馈，并用于评估CasePlan的 输出.

To exploit the fact that many construction projects are planned and work methods selectedbased on previous experience, a scheduling model using case-based reasoning is presented. This model not only adapts previous cases to suit a new project to be scheduled; it also extracts and summarizes planning knowledge from several cases and stores that as part of its knowledge base for future use. Thus the storage problem that arises when keeping many cases around is reduced, as planning knowledge is incrementally compiled. To efficiently retrieve this compiled knowledge or the cases, CasePlan uses a product model that describes at a general level what design elements are present in projects and how they structurally or functionally relate to another. The product model is used for case classification and learning planning knowledge. The research demonstrates the importance of product models in organizing and compiling knowledge. The CasePlan system resulting from this research will also be a state-of-the-art automated scheduler for construction. Its schedules will have enough detail to drive a discrete-event simulation of construction execution of the project, which can provide execution feedback and serve to assess the quality of CasePlan's output.
