Elevator Call Prediction Control for Shorter Waiting Times
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevators often operate inefficiently due to varying frequencies of calls across different floors in buildings, leading to prolonged waiting times for users, especially when the elevator is far from the call location.
Innovation Solution
An elevator control system that predicts target floors based on historical call data, generating matrices to determine optimal locations using a weighting and scoring system, and moves the elevator proactively to anticipated call areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the elevator remains at its last destination floor or automatically returns to a lobby to await the next call, then the elevator operation is simple and energy consumption is low, but the user waiting time increases and operation efficiency decreases
Solution Approach 1:
The control system performs preliminary actions by predicting future call locations based on historical data and proactively moving the elevator to these predicted floors before actual calls occur. This anticipatory approach reduces user waiting time by ensuring the elevator is already positioned near where calls are likely to happen, rather than reacting to calls after they occur.
Solution Approach 2:
The system implements feedback mechanisms by continuously collecting actual call data and comparing it with predicted call locations. This feedback loop allows the system to learn from past performance, refine its prediction algorithms, and improve future predictions, thereby progressively reducing waiting times while maintaining adaptive control.
2Productivity
If the elevator moves to predicted target floors proactively, then operation efficiency improves and waiting time reduces, but energy consumption increases and control complexity increases
Solution Approach 1:
The system applies preliminary action by moving the elevator to predicted target floors in advance based on historical call patterns. This proactive positioning improves operation efficiency by reducing idle time and positioning the elevator optimally before calls occur, rather than moving reactively after calls are registered.
Solution Approach 2:
The control system dynamically adjusts its behavior by continuously analyzing real-time and historical data to update prediction models. This dynamic adaptation allows the system to optimize movement patterns based on changing usage patterns, improving efficiency while avoiding unnecessary movements that would waste energy.
3Measurement precision
If the elevator uses historical call data and prediction algorithms, then call response accuracy improves, but data processing requirements and system complexity increase
Solution Approach 1:
The system uses feedback by continuously comparing actual call locations with predicted locations, using this information to refine prediction algorithms. This iterative learning process improves prediction accuracy over time while maintaining a manageable level of system complexity through adaptive rather than overly complex processing.
Solution Approach 2:
The prediction system performs self-service by automatically analyzing historical data and updating its own prediction models without requiring external intervention. This self-learning capability improves accuracy while keeping the system architecture relatively simple, as the system manages its own complexity through automated data processing and model refinement.
