Resource Allocation in Guided Transportation Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In guided transportation systems, resource allocation methods often fail when multiple vehicles compete for shared resource devices, leading to allocation failures and inefficiencies, as existing methods do not effectively manage resource contention and prioritization.
Innovation Solution
A method of resource allocation where resource controlling devices sequentially process lists of resource devices, with prioritization and first-come-first-serve basis handling, to ensure efficient allocation and release, using a communication network for vehicle requests and status updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource allocation is performed using a chain-based list where any single device failure causes entire route allocation to fail, then allocation reliability is improved, but allocation efficiency and system productivity deteriorate
Solution Approach 1:
The patent segments the resource allocation process into independent allocable units (individual resource devices) rather than treating the entire route as a single chain. Each resource device can be independently allocated or released, allowing partial success where some devices are allocated even if others are unavailable, thereby improving productivity while maintaining reliability through selective allocation
Solution Approach 2:
The system performs partial allocation by allocating only those resource devices that are available and can be assigned, rather than requiring complete allocation of all requested devices. This allows the system to achieve partial success and continue operations with available resources, improving overall system productivity while maintaining reliability through the ability to allocate what is possible
2Ease of operation
If resource devices are allocated on a first-come-first-serve basis without prioritization, then allocation simplicity is maintained, but resource utilization efficiency and system adaptability worsen
Solution Approach 1:
The patent implements dynamic prioritization where resource controlling devices can adjust allocation priorities based on current system conditions, vehicle requirements, and resource availability. This dynamic approach allows the system to adapt to changing conditions and optimize resource utilization efficiency while maintaining operational simplicity through automated priority management
Solution Approach 2:
The system incorporates feedback mechanisms where resource controlling devices monitor allocation status, vehicle requirements, and resource availability to dynamically adjust prioritization decisions. This feedback loop enables the system to optimize resource utilization efficiency while maintaining ease of operation through automated, condition-based priority adjustment
3Adaptability or versatility
If multiple vehicles compete for the same resource devices without effective contention management, then system adaptability is maintained, but allocation reliability and system stability worsen
Solution Approach 1:
The patent introduces resource controlling devices as intermediary components between vehicles and resource devices. These intermediaries manage contention by coordinating allocation decisions, evaluating vehicle priorities, and mediating access to contested resources. This intermediary layer maintains system adaptability while improving allocation reliability through structured contention management
Solution Approach 2:
The system performs preliminary evaluation of vehicle priorities and resource availability before allocation decisions are made. By assessing contention scenarios in advance and establishing priority orders, the system can resolve conflicts before they cause failures, thereby improving allocation reliability while maintaining adaptability through pre-established allocation rules

AI summary
A method of resource allocation by a resource controlling device includes receiving, from a sending device, a list of resource devices requested by a resource requesting device. Allocation of a first resource device on the list of resource devices is performed. A list of remaining resource devices is sent to a next resource controlling device if the first resource device on the list of resource devices is successfully allocated for the resource requesting device and the first resource device is not a last resource device on the list of resource devices. An allocation failure message is sent to the sending device if the first resource device on the list of resource devices is not successfully allocated for the resource requesting device.
