Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional transportation matching systems are used to match requesting devices with provider devices, then basic transportation coordination is achieved, but device imbalances and poor network coverage occur leading to increased latency and reduced responsiveness
Solution Approach 1:
The system performs preliminary actions by predicting future transportation requests using machine learning models and proactively positioning autonomous vehicles in anticipation of demand. This allows vehicles to be pre-positioned in high-demand areas before requests are made, reducing latency and improving network coverage responsiveness.
Solution Approach 2:
The system dynamically adjusts vehicle positioning strategies based on real-time conditions and predicted demand patterns. It continuously monitors contextual device information and modifies prepositioning instructions to adapt to changing transportation demands, ensuring optimal network coverage and reduced latency throughout the service area.
2Adaptability or versatility
If autonomous vehicles are statically assigned to fixed locations, then network coverage is maintained, but flexibility and responsiveness to changing transportation demands are reduced
Solution Approach 1:
The system employs dynamic prepositioning where autonomous vehicles receive updated navigation instructions based on real-time demand predictions and contextual information. This allows the system to maintain reliable network coverage while adapting vehicle positions to changing transportation needs, achieving both flexibility and reliability.
Solution Approach 2:
The system implements feedback mechanisms by monitoring actual transportation requests and vehicle performance, then using this information to refine predictions and adjust prepositioning strategies. This continuous feedback loop ensures the system maintains reliable coverage while becoming increasingly adaptable to changing patterns.
3Reliability
If more autonomous vehicles are deployed to improve network coverage, then coverage and responsiveness improve, but system complexity and computational resource requirements increase
Solution Approach 1:
The system segments the service area into multiple zones and assigns different prepositioning strategies to each segment based on local demand characteristics. This segmentation allows the system to manage complexity by handling smaller, more manageable regions independently while collectively achieving comprehensive network coverage.
Solution Approach 2:
The system changes key parameters such as prediction time horizons, zone sizes, and vehicle assignment criteria to optimize the balance between coverage and complexity. By adjusting these parameters dynamically, the system can scale to accommodate more vehicles while maintaining manageable computational requirements.
