Governments around the world are planning to ban sales of vehicles running on petroleum-based fuels as an effort reduce greenhouse gas emissions, and electric surfaced a solution decrease pollutants produced by transportation sector. As result, wireless power transfer technology has recently gained much attention convenient practical method for charging vehicles. In this paper, patent analysis is conducted identify emerging vacant areas transfer. Topics first extracted from patents text...

In the event of a maritime accident, surveying maximum area efficiently in least amount time is crucial for rescuing survivors. Increasingly, unmanned aerial vehicles (UAVs) are being used search and rescue operations. This study proposes method to generate path that covers all generated nodes shortest with multiple heterogeneous UAVs. The proposed model, which mixed-integer linear programming (MILP) model based on hexagonal grid-based decomposition method, was verified through simulation...

The rapid increase in international trade volume has caused frequent fluctuation of the vessels’ arrival time container terminals. In order to solve this problem, study proposes a methodology for rescheduling berth and quay cranes by updated information on vessels. A mixed-integer linear programming model was formulated allocation crane assignment we solved problem using rolling-horizon approach. Numerical experiments were conducted under three scenarios with empirical data from terminal...

Recently, last mile delivery has emerged as an essential process that greatly affects the opportunity of obtaining service market share due to rapid increase in business-to-consumer (B2C) market. Express companies are investing expand capacity hub terminals handle increasing volume. As for securing massive quantity by investment, must examine profitability between and price. This study proposes two strategies a company’s decision making regarding adjustment density price developing pricing...

With the development of maritime technology and equipment, most ships are equipped with an automatic identification system (AIS) to store navigation information. Over time, size data increases, rendering its storage processing difficult. Hence, it is necessary transform AIS into trajectories, then simplify trajectories remove unnecessary information that not related route shape. Moreover, topographic must be considered because otherwise, simplified trajectory can intersect obstacles. In this...

Abstract This study investigates a method for improving real-time decisions regarding the storage location of export containers while are arriving. To manage decision-making process, we propose two module-based data-driven dynamic stacking strategy that facilitates stowage planning. Module 1 generates Gaussian mixture model (GMM) specific to each container group weight classification. 2 implements as an online algorithm determine arriving in real time. Numerical experiments were conducted...

Abstract Global shipment volumes have been increasing due to changes in the business environment of e‐commerce and manufacturing. Consequently, container vessels carry more cargo for international trade, uncertainties terminal management. Terminal operators manage terminals by establishing a proactive schedule that responds disruptions such as vessel delays, introduction buffer time is representative strategy. In this study, analyzing historical delay data with machine learning, we propose...

Research on WPT (Wireless Power Transfer) technologies for locomotives based large-capacity wireless power transmission systems is underway, and interest pertaining to this technology also increasing in related industries. Although there a growing trend analysis both domestic overseas markets, research that supports strategies through detailed classification of the trends are insufficient. Therefore, study intended produce topics, which analyze locomotives, by topic modeling LDA (Latent...

To develop physically flexible electronics, high performance and mechanical stability of component materials devices are required. For a display, backplane with thin-film transistors (TFTs) must be developed. Gate insulating excellent electrical properties highly important to the development TFTs. We investigated nanocomposite gate dielectrics composed polyimide (PI) because their superior thermal stability, as well different inorganic HfO2, TiO2, Al2O3 nanoparticles dielectric constants....

In this study, we investigate inventory allocation and pricing strategies for retailers by incorporating demand information into the issue of during presale period. a system, offer goods at price lower than retail price. By offering products discount, may attract additional demand. addition, system enables to reduce uncertainty market establish strategy based on results presales. A Bayesian approach was employed analyze update information, formulated as newsvendor problem determine optimal...

As short turnaround times of vessels allow container terminals to serve a greater number vessels, several terminal operators strive reduce the vessel times. In this study, we introduce load scheduling problem integrating ship and yard operations enhance efficiency loading by considering changes in operation. We design two-phase hierarchical structure characteristic QC schedule obtain optimal sequence outbound containers. Phase 1, mixed-integer linear programming model that allocates...
