Relay Base Sorting Plan Adjustment for On-Time Package Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transportation delivery planning systems often overlook task time at relay bases, leading to delays in loading packages into connecting service trips, resulting in delayed deliveries.
Innovation Solution
A transportation and delivery planning apparatus that includes an assignment proposal creation unit, a sorting planning unit, and an evaluation determination unit. This apparatus creates an assignment proposal for service trips, devises a sorting plan for packages at relay bases, and evaluates the plan based on task time calculations to ensure packages are ready for connecting service trips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If task time at relay bases is not considered in transportation delivery planning, then the planning process is simpler and faster, but packages fail to be loaded into connecting service trips due to delays, resulting in delayed deliveries
Solution Approach 1:
The evaluation determination unit calculates task time in advance during the planning phase, and the sorting planning unit adjusts sorting schedules beforehand to ensure packages are ready before connecting service trips. This preliminary calculation and adjustment prevents delays without requiring complex real-time interventions.
Solution Approach 2:
The evaluation determination unit provides feedback by calculating task time and comparing it against available time windows. Based on this feedback, the sorting planning unit and assignment proposal creation unit adjust their plans to ensure reliable loading, creating a closed-loop planning system that improves delivery reliability.
2Reliability
If task time at relay bases is considered in transportation delivery planning, then delayed deliveries are suppressed, but the planning process becomes more complex and time-consuming
Solution Approach 1:
The evaluation determination unit performs task time calculation during the initial planning phase rather than during execution. This preliminary action allows the system to identify time constraints early and adjust plans accordingly, avoiding the need for time-consuming real-time adjustments while maintaining planning accuracy.
Solution Approach 2:
The system replaces manual, ad-hoc time calculations with an automated evaluation determination unit that systematically calculates task time based on predefined parameters. This substitution reduces the time required for planning while ensuring consistent and accurate time management.
3Productivity
If packages are sorted at relay bases according to conventional methods without task time consideration, then the sorting process is faster, but packages may not be ready for connecting service trips
Solution Approach 1:
The sorting planning unit creates a detailed sorting plan in advance that accounts for task time requirements. Packages are pre-sorted and prepared according to the calculated task time, ensuring they are ready for connecting service trips without requiring last-minute rushes that compromise reliability.
Solution Approach 2:
The sorting plan is dynamically adjusted based on the calculated task time and available time windows. The system flexibly optimizes sorting schedules to match actual constraints, allowing high-speed sorting while ensuring packages are ready on time for connecting trips.

AI summary
A transportation and delivery planning apparatus and method suppresses the delayed delivery of packages and is designed to: create an assignment proposal to assign each of transportation delivery instructions to each of service trips for which a service plan was created in advance; devise a sorting plan for packages at a relay base on the basis of the created assignment proposal for each created transportation delivery instruction; calculate task time of a sorting task at the relay base according to the sorting plan and evaluate a transportation delivery plan based on a calculation result; and change the sorting plan or modify the assignment proposal, based on an evaluation result of the transportation delivery plan, so that the sorting task for the respective packages will be completed at the relay base before a departure of the service trip for a connecting destination assigned to each of the transportation delivery instructions.
