Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transportation planning systems face inefficiencies due to conflicting goals such as minimizing costs and ensuring on-time delivery, particularly when utilizing truck-based transportation with drop trailer arrangements, which are not adequately considered in existing algorithms and methods.
Innovation Solution
The development of computer-based systems and methods that consolidate orders and plan loads by incorporating drop trailer arrangements, allowing for the selective assignment of shipments to loads and providing actionable plans that optimize utility measurements by leveraging drop trailer capabilities, such as flexible trailer usage and reduced wait times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If live (un)load situations are used where drivers stop and wait while trucks are loaded or unloaded, then cargo loading/unloading can be completed, but driver time is wasted and transportation efficiency decreases
Solution Approach 1:
The system segments the loading/unloading process from the transportation process by introducing intermediate staging areas. Trailers are dropped off and picked up at designated locations without requiring driver presence during the actual cargo transfer, separating these operations in time and space.
Solution Approach 2:
The patent introduces intermediate facilities (staging areas, cross-dock locations) as mediators between the truck and final destination. These intermediaries handle the loading/unloading operations, allowing trucks to bypass waiting time while cargo is transferred through the intermediate facility.
2Productivity
If drop trailer arrangements are implemented to reduce waiting time, then transportation efficiency improves, but system complexity increases due to coordination requirements
Solution Approach 1:
The system implements feedback mechanisms through real-time tracking and communication systems that monitor trailer locations, staging area capacity, and route status. This feedback enables dynamic coordination decisions, optimizing the drop trailer arrangement implementation while managing system complexity.
Solution Approach 2:
The patent replaces manual coordination mechanisms with automated information systems, including GPS tracking, electronic communication platforms, and centralized management systems that coordinate drop trailer operations without requiring complex human-to-human communication.
3Productivity
If multi-stop loads are optimized using traditional routing algorithms, then delivery routes are established, but drop trailer opportunities are missed leading to suboptimal utility measurements
Solution Approach 1:
The system performs preliminary identification and evaluation of drop trailer opportunities during the route planning phase. By analyzing destination characteristics, facility capabilities, and route parameters in advance, the system proactively incorporates drop trailer arrangements into the optimized routing decisions before execution.
Solution Approach 2:
The patent introduces an intermediary optimization layer that sits between traditional routing algorithms and final route determination. This intermediary component specifically evaluates drop trailer opportunities and integrates them into the overall route optimization, ensuring this information is not lost in the optimization process.

AI summary
Systems, methodologies, media, and other embodiments associated with transportation planning in light of drop trailer arrangements are described. One exemplary computer-implemented method embodiment includes receiving orders that describe items to be delivered to facilities as controlled by order requirements. The method may also include accessing a transportation planning model that includes information concerning shipping modes and carriers by which an order can be delivered to a facility. The transportation planning model may also include data concerning drop trailer arrangements between facilities and the carriers. The method may also include selectively consolidating orders into shipments based on the transportation planning model and the availability of a drop trailer arrangement. The method may also include selectively assigning shipments to loads based on the transportation planning model and the availability of a drop trailer action. The method may output an actionable plan of loads stored, for example, on a computer-readable medium.
