Blockchain-Enabled MRO: Enhancing Transparency and Efficiency in Aircraft Maintenance

Arthur C. Dela Peña, Meredith I. Rutao, Robert P. Corpuz — Wed, 11 Dec 2024 00:00:00 +0000

Blockchain technology is emerging as a transformative solution for addressing challenges in aviation Maintenance, Repair, and Overhaul (MRO), particularly in enhancing transparency, efficiency, and data security. This study explores the integration of blockchain within MRO operations in the Philippine aviation industry, aiming to assess its impact on data management, part authentication, and regulatory compliance. Utilizing a mixed-methods approach, data were collected through surveys, interviews, and document analysis involving MRO professionals, blockchain experts, and industry stakeholders. Findings indicate that blockchain can significantly improve record transparency, reduce counterfeit risks, and streamline verification processes, leading to more efficient maintenance cycles. Blockchain’s decentralized, tamper-proof ledger system was noted to address inefficiencies in data reconciliation and enhance traceability, which are critical for regulatory compliance. However, challenges such as cost, scalability, and integration with legacy systems were identified as barriers to adoption. The study recommends piloting blockchain in specific MRO functions, integrating it with IoT for predictive maintenance, and collaborating with regulators to develop industry standards. Future research should focus on blockchain’s long-term cost implications, its synergy with artificial intelligence for predictive analytics, and strategies to overcome regional adoption challenges. The study underscores blockchain’s potential to modernize MRO practices and offers insights into its practical application in a developing market.

Determination and Implementation of the Shortest Path for Emergency Evacuation at the Bali Dwipa University Building: A Case Study

Wed, 11 Dec 2024 00:00:00 +0000

This study applies the Floyd Warshall Algorithm to determine the shortest emergency evacuation route in the Bali Dwipa University building. An efficient and fast evacuation route is essential to ensure the safety of all building occupants. This study was conducted at Bali Dwipa University, Denpasar, Bali, to evaluate and map the building layout to the third floor as part of the evacuation system analysis. The research methodology involves collecting primary and secondary data and direct manual measurements in the field. The research stages begin with creating a building plan, which includes collecting information on the layout and existing evacuation procedures. Furthermore, using a precision measuring instrument, mapping the relationship between objects is carried out with manual measurements of the distance between rooms to determine the evacuation route to a safe point. The results of these measurements are analyzed to build a spatial structure by selecting the nodes and edges in the graph that represent the building. Then, the Floyd-Warshall algorithm is implemented to find the shortest path from each room to the gathering point, located in the first floor's lower front yard. The study results indicate that applying the Floyd-Warshall algorithm effectively determines the shortest path from each node in the Bali Dwipa University building to the main evacuation point. By mapping the nodes from the 1st to the 3rd floor and measuring the distance between the nodes, this study produces a clearly defined optimal evacuation route. This study is expected to improve the efficiency of evacuation routes and the safety of occupants in emergencies.

Exploration of Contractors’ Management Strategies in Delivering Successful Construction Projects in Ghana: A Factor Analysis Approach

This study explores the management strategies used by contractors in Ghana during the construction stage to successfully deliver construction projects. The research employed a descriptive cross-sectional survey to gather data from 375 site managers working in medium and large-sized construction firms in Ghana. Principal Component Analysis (PCA) was used to reduce the 32 strategies identified through the literature review to 27 sub-strategies. The analysis identified four key strategy categories that contribute to successful project delivery: effective project planning, monitoring and control, stakeholder collaboration, and integration of digital technologies. The findings provide valuable insights and recommendations to enhance project management practices within Ghana's construction industry, aiming to improve project delivery and increase stakeholder satisfaction.
