Improving facilities lifecycle management using RFID localization and BIM-based visual analytics

摘要: Indoor localization has gained importance as it the potential to improve various processes related lifecycle management of facilities, such manual search find assets. In operation and maintenance phase, lack standards for interoperability difficulties processing large amount accumulated data from different sources cause several process inefficiencies. For example, identifying failure cause-effect patterns in order prepare plans is difficult due complex interactions interdependencies between building components existence multiple, fragmented sources. Building Information Modelling (BIM) emerging a method creating, sharing, exchanging managing information throughout buildings. Radio Frequency Identification (RFID), on other hand, emerged an automatic collection technology, been used applications facilities. The previous research author proposed permanently attaching RFID tags assets where memory populated with their taken standard BIM database enhance processes. This thesis builds this framework investigates methods supporting by using BIM, visual analytics. It usage location-related that can be retrieved are stored tags. also technology indoor RFID-equipped handheld readers. proposes location saved attached fixed locate them floor plan. These act reference moveable received signal pattern matching clustering algorithms. Additionally, extending incorporate information. provides opportunity interrelate predefined relationships. purpose, requirements’ gathering performed add new entities, types, relationships, property sets BIM. Moreover, visualization help facilities managers make better decisions phase lifecycle. knowledge-assisted BIM-based analytics approach root-cause detection integrated interactive exploiting heuristic problem solving ability field experts.
