Logistics Delivery Notification System for Reducing Package Redelivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current logistics systems face challenges in accurately predicting when users will return to their destinations, leading to high rates of package redelivery due to the inability to determine the expected arrival time with sufficient accuracy.
Innovation Solution
An information providing method that calculates the expected arrival time of a user at their destination by acquiring their current location, determining the visiting duration based on the type of location, and calculating the necessary traveling duration, allowing for the transmission of targeted messages to encourage users to be present at the time of delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the delivery system uses general delivery scheduling without accurate user location tracking, then the system complexity is reduced, but the delivery reliability deteriorates due to high redelivery rates
Solution Approach 1:
The system performs preliminary actions by tracking user location and calculating expected arrival times before the scheduled delivery time. This allows the system to predict whether the user will be at the destination during delivery, enabling proactive communication and reducing redelivery rates.
Solution Approach 2:
The system implements feedback by notifying users of their expected arrival time relative to the scheduled delivery time and requesting confirmation of their presence. This feedback loop allows the system to adjust delivery plans based on user availability, improving delivery reliability.
2Measurement precision
If the system calculates expected arrival time using detailed location data and visiting duration, then the measurement precision of user availability improves, but the loss of information processing increases
Solution Approach 1:
The system applies local quality by storing and using visiting duration data specific to each location type (e.g., workplace, home, shopping center). This allows the system to calculate expected arrival times with high accuracy using only the necessary location-specific parameters rather than processing all possible user data.
3Loss of time
If the system sends notifications to all users regardless of their location, then the ease of operation is maintained, but the loss of time for unnecessary communications increases
Solution Approach 1:
The system applies partial action by sending notifications only to users whose expected arrival time is within a certain range of the scheduled delivery time. This avoids unnecessary communications with users who will definitely be absent or definitely present, reducing time loss while maintaining operational simplicity through automated threshold-based filtering.
