Transportation Plan Optimization for Holding Time and Dispatch Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transportation planning methods fail to consider the holding time of transportation objects from their arrival at the starting point to the arrival of the vehicle, leading to inefficiencies and increased mental burden on passengers or potential deterioration of perishable goods.
Innovation Solution
An information processing method that creates a transportation plan by considering the sum of holding costs and transportation costs, arranging starting and ending points in time series, and optimizing the plan to minimize the total holding and transportation time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional transportation planning methods are used that focus on minimizing vehicle operation time and distance, then vehicle efficiency is improved, but the holding time of transportation objects at the starting point increases
Solution Approach 1:
The patent applies preliminary action by considering the holding time from the arrival of transportation objects at the starting point to the arrival of the vehicle in advance when creating the transportation plan. The plan creation unit generates transportation plans that minimize the sum of holding times and transportation costs, rather than only optimizing vehicle operation efficiency. This allows the system to proactively reduce waiting times for transportation objects at starting points by pre-coordinating vehicle dispatch timing with object arrival times.
2Speed
If the vehicle operation time is minimized, then the vehicle can respond faster to future requests, but the transportation object waits longer at the starting point
Solution Approach 1:
The patent applies parameter changes by modifying the optimization objective function from minimizing only vehicle operation time to minimizing the sum of holding times and transportation costs. This parameter change in the evaluation criterion allows the system to balance between vehicle response speed and object waiting time, generating transportation plans that consider both aspects simultaneously rather than prioritizing only vehicle efficiency.
3Device complexity
If transportation plans are created without considering holding time, then calculation complexity is reduced, but overall transportation efficiency deteriorates
Solution Approach 1:
The patent applies merging by combining the holding time consideration with the existing transportation cost minimization framework. The plan creation unit integrates holding time calculations into the existing plan evaluation process, merging two previously separate optimization objectives (holding time and transportation cost) into a unified evaluation criterion. This allows the system to consider multiple factors without requiring completely separate calculation systems.

AI summary
An information processing method includes acquiring a transportation request for each of one or more transportation objects, the transportation request including a starting point, an ending point, and a first arrival date/time that indicates a date and time at which each of the one or more transportation objects arrives at the starting point, creating a transportation plan on the basis of a sum of one or more holding costs that correspond to a difference between the first arrival date/time and a second arrival date/time that indicates a date and time at which one or more vehicles transporting the transportation objects arrive at the starting point for each of the one or more transportation objects, and one or more transportation costs required for transporting each of the one or more transportation objects from the starting point to the ending point, and outputting the transportation plan.
