Hydrogen Refueling Scheduling for Cargo Handling Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of hydrogen gas as fuel in cargo handling apparatuses, such as gantry cranes, leads to potential fuel depletion during operations and increased frequency of fuel supply, resulting in decreased cargo handling efficiency.
Innovation Solution
A management system that allocates cargo handling operation data to each apparatus, creating an operation schedule with designated cargo handling times and spare times, and schedules hydrogen gas supply during spare times to maintain efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If hydrogen gas is used as fuel in cargo handling apparatuses, then carbon dioxide discharge is suppressed, but cargo handling efficiency decreases due to frequent fuel supply operations
Solution Approach 1:
The management system performs preliminary scheduling of fuel supply operations during spare times before they are critically needed. By anticipating fuel consumption patterns and scheduling supply operations in advance during non-cargo handling periods, the system prevents fuel depletion without interrupting cargo handling operations, thus maintaining efficiency while achieving environmental goals
2Reliability
If fuel supply operations are increased in frequency, then fuel depletion is prevented, but cargo handling efficiency decreases
Solution Approach 1:
The management system automatically monitors fuel levels, calculates consumption patterns, and schedules supply operations without manual intervention. This self-service approach optimizes fuel supply timing based on actual usage patterns, ensuring reliable fuel availability while minimizing disruptions to cargo handling efficiency through automated, data-driven decision-making
3Productivity
If cargo handling operations are continuous, then cargo handling efficiency is maintained, but fuel supply timing becomes constrained
Solution Approach 1:
The management system dynamically adjusts fuel supply schedules based on real-time cargo handling operations and fuel consumption patterns. By continuously monitoring operational data and adapting the scheduling algorithm, the system identifies optimal spare time windows for fuel supply that minimize impact on cargo handling efficiency while ensuring fuel availability, making the scheduling process flexible and responsive to changing conditions
