Research on key indicators and evaluation system for future wide-body aircraft cargo loading systems based on the CRITIC method
With the profound transformation of the global trade landscape and the vigorous development of e-commerce, air cargo, as a crucial component of the modern logistics system, is facing unprecedented opportunities and challenges. Wide-body aircraft serve as the primary workhorses for intercontinental air cargo transport, and their cargo loading systems are the direct task execution systems for cargo handling. During the overall design of future wide-body aircraft, research gaps persist in evaluating cargo loading systems and defining potential design indicators. These gaps can affect overall aircraft performance, cargo transport capacity, cargo hold loading/unloading efficiency, aircraft turnaround time, safety, and reliability. Based on the CRITIC (Criteria Importance Through Intercriteria Correlation) objective weighting method, this study systematically explores the evaluation indicator system and key design indicators for future wide-body aircraft cargo loading systems. It constructs an evaluation framework covering multiple dimensions such as basic system design performance, operational and economic efficiency, safety and reliability, intelligence and digitalization level, and environmental and sustainability performance. Furthermore, it identifies key design indicators and technical pathways for future cargo loading systems. The research demonstrates that establishing a scientific and comprehensive evaluation system is of great significance for promoting the innovative development of wide-body aircraft cargo loading systems and enhancing the overall efficiency of air cargo transport.

Experimental study on the diffusion patterns of novel clean fire extinguishing agents in concealed areas of civil aircraft cargo compartments
This study constructs a 1:1 physical platform simulating the concealed areas of an Airbus A330-300 cargo hold and conducts experiments using handheld onboard fire extinguishers to investigate the diffusion characteristics of the novel clean extinguishing agent and its concentration distribution in concealed spaces. The results indicate that the extinguishing agent exhibits a top-down diffusion trend along the vertical axis. Along the longitudinal diffusion direction, the agent concentration is highest near the injection point and gradually decreases with increasing distance from the source. During diffusion, the agent struggles to ascend to the upper concealed spaces. By directing the spray toward obstructing equipment or structures, a portion of the agent can penetrate shielded corners.

Into the raging sea : thirty-three mariners, one megastorm and the sinking of the El Faro
In the tradition of The Perfect Storm and Into Thin Air, Rachel Slade's Into the Raging Sea is a nail-biting account of the sinking of the American container ship El Faro, the crew of 33 who perished onboard, and the destructive forces of globalization that put the ship in harm's way.
A Technical Analysis Regarding the Use of Autonomous Ships in the Black Sea Basin
Over the last few years, ships that can operate with little or no crew have moved from a bold concept into something that may soon become reality. The Black Sea is a challenging yet interesting place to observe how such vessels operate, as it has busy routes, unpredictable weather, and occasionally security issues. In this paper, we share our approach to examining the use of Maritime Autonomous Surface Ships (MASS) for cargo transportation between Europe and Asia. We followed the discussions at International Maritime Organization (IMO) regarding MASS and also examined new environmental rules, such as those from the European Green Deal. To make it more concrete, we used the Romanian training ship Albatros as an example. Using normal wind and sea data, we attempted to estimate the amount of energy that could be saved, the reduction in fuel and emissions, and the improvement in navigation safety that could result from fewer people being exposed to risk. By combining numbers with real-world context, we provide, hopefully, a down-to-earth view of what autonomous shipping might mean for the Black Sea.

Transportation aircraft class F cargo compartments method of compliance study on fire protection and analysis
Cargo compartments are important components of conventional transport category aircraft, serving both passenger and freight operations. Following a fire-related accident on a South African Airways flight, the FAA introduced Amendment 25-142 to revise the definition of Class B compartments and establish Class F compartments, thereby enhancing fire protection standards. This paper provides a detailed definition of Class F compartments, analyzes compliance methods for their key design elements, and proposes fire protection design recommendations. A reference compliance approach, validated through experimental data, is presented. The experimental results demonstrate the effectiveness of the proposed methodology in achieving fire suppression and compartment isolation requirements.

Sail, Steam, and Diesel
Water transportation has played a key role in the Great Lakes region’s settlement and economic growth, from providing entry into the new lake states to offering cheap transportation for the goods they produced. There are numerous tales surrounding the Great Lakes shipping trade, but few storytellers have addressed the factors that influenced the use, design, and evolution of the ships that sailed the inland seas. Sail, Steam, and Diesel: Moving Cargo on the Great Lakes provides a comprehensive overview of the evolution of Great Lakes ships over the centuries, from small birch-bark canoes originally used in the region to the massive thousand-footers of today. The author also looks at the economics of vessel operation in the context of the expanding scope of the shipping industry, which was crucial in catapulting America into becoming an industrial juggernaut. The captains of industry and the sailors whose labor propelled the trade populate this account, which also offers solemn acknowledgment of the high cost paid in both lost ships and lives. Although they might not realize it, millions of Americans have owed their livelihoods to the Great Lakes boats, and this volume is an excellent way to recognize the importance of this regional industry.

Measuring delivery route cost trade-offs between electric-assist cargo bicycles and delivery trucks in dense urban areas
IntroductionCompleting urban freight deliveries is increasingly a challenge in congested urban areas, particularly when delivery trucks are required to meet time windows. Depending on the route characteristics, Electric Assist (EA) cargo bicycles may serve as an economically viable alternative to delivery trucks. The purpose of this paper is to compare the delivery route cost trade-offs between box delivery trucks and EA cargo bicycles that have the same route and delivery characteristics, and to explore the question, under what conditions do EA cargo bikes perform at a lower cost than typical delivery trucks?MethodsThe independent variables, constant variables, and assumptions used for the cost function comparison model were gathered through data collection and a literature review. A delivery route in Seattle was observed and used as the base case; the same route was then modelled using EA cargo bicycles.Four separate delivery scenarios were modeled to evaluate how the following independent route characteristics would impact delivery route cost - distance between a distribution center (DC) and a neighborhood, number of stops, distance between each stop, and number of parcels per stop.ResultsThe analysis shows that three of the four modeled route characteristics affect the cost trade-offs between delivery trucks and EA cargo bikes. EA cargo bikes are more cost effective than delivery trucks for deliveries in close proximity to the DC (less than 2 miles for the observed delivery route with 50 parcels per stop and less than 6 miles for the hypothetical delivery route with 10 parcels per stop) and at which there is a high density of residential units and low delivery volumes per stop.ConclusionDelivery trucks are more cost effective for greater distances from the DC and for large volume deliveries to one stop.
