Description

Smart facility management system and method {SMART FACILITY MANAGEMENT SYSTEM AND METHOD}

The present invention relates to a smart facility management system and method, and more particularly, to a smart facility management system and method that can support decision-making by linking real-time FM data and BIM data.

For efficient facility management, information at the design and construction stages should be collected and automatically linked to the maintenance process. Given the documentation of information needed for effective facility maintenance and operation, it is important to find effective ways to collect, access and update information.

In order to use the computer-based maintenance management system for the maintenance of existing buildings where the information is stored as paper documents, facility and other building information must be converted into digital files. Cost is consumed. That is, most of the information required for facility maintenance of existing buildings exists in the form of documents such as existing 2D drawings and specifications, and information management work efficiency is reduced by re-entering the facility maintenance system.

When generating BIM (Building Information Modeling) information at the design and construction stages, the information required for the facility maintenance phase must be modeled, but the BIM information is not yet fully integrated with the existing facility maintenance system.

In the existing facility management system, data such as drawings, history information, and related documents and site information are distributed into legacy data such as Excel, Word, and drawings. Information verification is often repetitive, such as requiring manual visits to facility management documentation or sites.

The process of identifying facility-related drawings or historical information is complex. For example, if the historical information is confirmed and the company's facility is out of warranty and a contract is required with a new facility management company, the data requested by the company for maintenance work may be returned to the facility management document repository or management information system and site. Check that the delivery process is repeated over and over again.

Knowledge DB extracts useful information through big data mining from big data analyzed in big data analysis.

Decision systems (DDS) support facility managers' decision-making through information extracted from knowledge databases. For example, when a user accesses Intelligent FM and requests information on the first floor stairs of the site, the DDS retrieves the information from the knowledge DB and visualizes it using MR / VR / AR.

DDS can associate BIM and FM data under the condition that GUID or classification system ID, which is a primary key (PK) of BIM, is designated and the same key is present in FM data.

The FM service provides (performs) an FM service registered in a service container. In addition, business process management (BPM) rules are stored in the service container, and the BPM controls the service execution order or conditions. Here, in case of structural damage such as a wall or a pillar, the FM service may be a function of notifying and alerting the administrator or staff of the facility when an abnormal value appears in the sensed data. Another example is a service that tells an administrator that someone has reserved a space but is not using it when it is not actually used.

The service device 200 may measure and manage a smart management level using a Capability Maturity Model Integration (CMMI) -based maturity model Smart FM Maturity Model (SFMM). Maturity model SFMM is defined as shown in [Table 2].
