Delivery Verification Using Time Window Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current delivery verification methods are inefficient, particularly for complex delivery locations, as they often require additional steps and resources, such as photographs, which can decrease the overall efficiency of the delivery process and increase memory and network usage.
Innovation Solution
A method that verifies deliveries based on the comparison of the actual delivery time to an estimated time of delivery, allowing for automatic verification when times align and requiring additional evidence only when they do not, thereby optimizing the collection of evidence and reducing inefficiencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If delivery verification is performed using traditional methods (photographs, additional evidence collection), then verification accuracy is improved, but delivery efficiency deteriorates due to increased time and steps required
Solution Approach 1:
The system pre-establishes a predefined time window around the estimated delivery time before the actual delivery occurs. This preliminary setup allows for automated verification based on timing data alone when the delivery falls within this window, eliminating the need for subsequent photograph collection or additional evidence gathering, thus resolving the contradiction between verification accuracy and delivery efficiency
Solution Approach 2:
The verification system uses the delivery time data itself to perform the verification function. When the actual delivery time falls within the predefined window around the estimated time, the time data automatically serves as sufficient verification evidence, making the verification process self-sufficient without requiring external evidence collection, thereby maintaining both accuracy and efficiency
2Reliability
If additional evidence (photographs) is collected for all deliveries, then verification reliability is improved, but resource consumption (memory, network) increases
Solution Approach 1:
The system applies different verification requirements to different delivery cases based on local conditions. Deliveries within the predefined time window use only time-based verification (no photographs), while deliveries outside the window require additional evidence. This localized approach to verification quality reduces overall resource consumption while maintaining reliability where needed
Solution Approach 2:
Instead of requiring full evidence collection (photographs plus time data) for all deliveries, the system uses only partial action (time data alone) for the majority of deliveries that fall within the predefined time window. This partial verification approach significantly reduces memory and network resource consumption while maintaining verification reliability through the time-based criterion
3Reliability
If delivery verification requires multiple steps and evidence collection, then verification thoroughness is improved, but the complexity of the delivery process increases
Solution Approach 1:
The verification process is segmented into two distinct paths: a simplified path for deliveries within the predefined time window (using only time-based verification) and a comprehensive path for deliveries outside the window (requiring additional evidence). This segmentation reduces overall process complexity by providing a streamlined verification route for the majority of on-time deliveries while maintaining thoroughness for late deliveries

AI summary
A method, apparatus and computer program product are provided for delivery verification. In the context of a method, an estimated time of delivery to a respective delivery location is determined. The estimated time of delivery is at least partially based upon a first location along a delivery route and the respective delivery location. The method also includes determining a delivery time at which a delivery attempt or a delivery was indicated to be made to the respective delivery location and performing a comparison of the delivery time to the estimated time of delivery. The method further includes differently verifying the delivery attempt or the delivery to the respective delivery location depending upon the comparison of the delivery time to the estimated time of delivery.
