Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors and complex data analysis are used to improve anomaly detection accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system divides the facility into multiple zones with specific surveillance requirements. Different sensor types and analysis algorithms are assigned to different zones based on their specific needs, allowing high precision where required while maintaining simpler operation in other areas. This segmentation resolves the contradiction by localizing complexity to where it provides maximum benefit.
Solution Approach 2:
The central computing unit serves multiple functions: it processes data from various sensor types, performs anomaly detection, classifies anomalies by severity, and coordinates mobile robotic platforms. This multi-functionality consolidates complexity into a single universal platform rather than requiring separate specialized systems for each function.
2Reliability
If continuous surveillance of multiple facility elements is implemented, then reliability of security monitoring is improved, but loss of time for data processing increases
Solution Approach 1:
The system performs preliminary classification of surveillance data into normal and anomalous states using automated algorithms. By pre-processing and categorizing data continuously, the system maintains high reliability monitoring while reducing the time required for manual analysis of each data point, as anomalies are automatically identified and prioritized.
Solution Approach 2:
The system implements feedback loops where classification results are continuously refined based on historical data and pattern recognition. This allows the system to learn from past anomalies and improve detection accuracy over time, maintaining high reliability while reducing processing time through optimized algorithms that adapt to facility-specific patterns.
3Measurement precision
If automated classification algorithms are used to reduce uncertainty in security evaluation, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The classification algorithms are designed to be dynamic and adaptive, adjusting their complexity based on the specific surveillance context. The system can switch between simple rule-based classification and more complex machine learning models depending on the situation, allowing high precision when needed while maintaining simpler operation during normal conditions.
Solution Approach 2:
The system applies complex classification algorithms selectively to data that requires detailed analysis, rather than applying them uniformly to all surveillance data. By using partial action (applying complex algorithms only where necessary), the system achieves high precision for critical evaluations while avoiding the time and computational cost of applying full complexity to every data point.
4Measurement precision
If mobile robotic platforms are deployed for enhanced data acquisition, then measurement precision is improved, but device complexity and loss of time increase
Solution Approach 1:
Mobile robotic platforms serve as intermediary devices that physically transport sensors to difficult-to-reach areas of the facility. Rather than installing fixed sensors throughout the entire facility, the robotic platform acts as a mobile intermediary that can be deployed only when and where enhanced data acquisition is needed, reducing overall system complexity while maintaining high measurement precision for critical areas.

AI summary
Systems and methods for surveillance of a facility including facility elements. The system includes a central computing unit providing a digital model of the facility providing topological or logical or functional relationships of the facility elements, surveillance sensors adapted for surveillance of a plurality of the facility elements and for generation of surveillance data, communication means for transmitting data from the surveillance sensors to the central computing unit, and state derivation means configured to analyse the surveillance data and derive a state of a respective facility element. The central computing unit is configured to record a state pattern by combining states of at least one facility element based on at least one relationship of the facility element provided by the facility model, provide a state pattern critical-noncritical classification model which considers relationships provided by the facility model, and perform a criticality-classification based on the relationship.
