Cloud Service Scheduling System for Building Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building management systems, such as fire alarm and intrusion systems, face challenges in efficient service scheduling and validation due to lack of real-time data on necessary service, inadequate tracking of service visits, and insufficient records for certification, leading to costly disruptions and potential system failures.
Innovation Solution
A service management system that collects detailed installation and service data, using predictive analysis to generate accurate models for service duration and cost estimation, and aggregates data to schedule visits and evaluate technician performance, providing validation for service completion and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional service scheduling methods are used without real-time data collection, then service visits can be scheduled regularly, but service costs increase and system failures may occur due to inadequate timing
Solution Approach 1:
The system performs preliminary data collection and predictive analysis before service visits are needed. By accumulating operational data from building management systems and analyzing it predictively, the system determines optimal service timing in advance, preventing system failures before they occur while avoiding unnecessary service visits.
Solution Approach 2:
The system implements continuous feedback loops by collecting real-time operational data from building management systems, analyzing the data to determine service needs, and using this information to schedule subsequent service visits. This feedback mechanism ensures service is performed at the optimal time based on actual system conditions rather than fixed schedules.
2Productivity
If detailed service data collection is implemented, then service scheduling accuracy and technician performance evaluation improve, but system complexity and data processing requirements increase
Solution Approach 1:
The service management system performs multiple functions through a single integrated platform: it collects operational data, performs predictive analysis, schedules service visits, tracks technician performance, and generates compliance reports. This multi-functional approach consolidates what would otherwise require separate systems, managing complexity while delivering comprehensive service management capabilities.
Solution Approach 2:
The system automatically collects service data from building management systems without requiring manual data entry by technicians or administrators. The predictive analytics and scheduling functions operate autonomously based on collected data, reducing the need for human intervention in data collection and processing while improving accuracy and consistency.
3Measurement precision
If predictive analysis models are developed using accumulated service data, then service duration and cost estimation accuracy improve, but data accumulation time and processing complexity increase
Solution Approach 1:
The system continuously accumulates and pre-processes service data in the background as it becomes available from building management systems. By the time predictive analysis is needed, relevant data has already been collected and prepared, enabling rapid model development and accurate service estimations without requiring extended data accumulation periods when service scheduling is needed.
Data Source
AI summary
A service management system facilitates and validates service on building management systems. A connected services database stores service events based on services performed on devices of different building management systems along with information about technicians performing the services, buildings containing the building management systems and devices being serviced. A service data aggregator retrieves the service events from the connected services database and generates prediction information and validation information based on the service events and other information. The prediction information includes a predicted duration and cost of different types of service as well as a predicted service interval for devices requiring periodic service. The validation information includes whether services performed by a particular technician need to be reviewed or audited, or whether the particular technician needs additional training or oversight, based on comparing the duration of services performed by the particular technician to the duration of services performed by all technicians.
