Location-Aware Construction

如果不断了解材料、设备和劳动力的位置，则可以更有效地管理建筑项目。位置信息用于规划施工活动、工作时间表、材料和设备供应、现场访问以及其他方面，如安全和工作区域的流动性。该研究计划将开发一个框架，从各种传感器获取位置数据，分析建设项目背景下的整体情况，并为建设参与者提供改进的信息和决策支持。这个“位置感知构建”框架由工具组成，这些工具将在特定的构建过程中集成“位置”、“进度”和“资源与活动相互依赖”的知识。研究目标将通过利用传感和无线网络引擎来获取位置信息，然后开发一个位置感知引擎来估计和可视化地表示更可靠的空间信息，一个认知引擎用于知识管理和评估活动和资源位置的相互依赖性，以及基于位置的应用引擎来实现。将使用先进的计算技术，包括数据融合、学习和适应、软计算（包括模糊逻辑、概率推理和粗糙集理论）、基于证据的推理、信念函数理论、进化计算和不确定性管理。本研究计划将改进用于重型建筑项目的施工方法、工具和技术，以协助决策者、施工人员、项目和设施管理人员、安全工程师和检查员。加拿大建筑行业的好处包括显著的成本和时间节约，生产力的提高，以及建筑区域内的安全性和流动性的增强。加拿大建筑公司也将从这个研究项目中直接受益，通过整合由此产生的先进方法和工具，提高他们在大型项目中的竞争地位。

Construction projects can be managed more effectively if the locations of materials, equipment, and the workforce are continuously known. Location information is used to plan construction activities, work schedules, materials and equipment supply, site access, and other aspects such as safety and work-zone mobility. This research program will develop a framework to acquire location data from various sensors, analyze the overall situation in the context of the construction project, and provide improved information and decision support for construction participants. This "Location-Aware Construction" framework consists of tools that will integrate the knowledge of "location", "schedule", and "resource and activity interdependencies" within the specific construction processes. The research objectives will be achieved by utilizing a Sensing and Wireless Network Engine to acquire location information, and then developing a Location Awareness Engine that estimates and visually represents more reliable spatial information, a Cognitive Engine for knowledge management and assessment of interdependencies of activities and location of resources, and Location-based Application Engines. Advanced computation techniques will be used, including data fusion, learning and adaptation, soft computing (including fuzzy logic, probabilistic reasoning, and rough set theory), evidence based reasoning, belief function theory, evolutionary computing, and uncertainty management. This research program will improve construction methods, tools, and techniques used for heavy construction projects, to assist decision makers, constructors, project and facility managers, safety engineers, and inspectors. Benefits for Canada's construction industry include notable cost and time savings, improved productivity, and enhanced safety and mobility within the construction zones. Canadian construction firms will also benefit directly from this research project, by incorporating the resulting advanced methodologies and tools that boost their competitive position for large projects.
