Автоматизация обработки аэронавигационной информации на основе многоагентных технологий

Progress in the development of computer engineering provides an opportunity to address a wider variety of challenges using computer software systems. The task of automatic aeronautical navigation information processing is referred to the number of such issues. This stipulates the necessity to adopt new approaches to design and develop similar systems. One of these approaches is based on the application of the collective activity idea of a set of agents – multi-agent technologies. In this regard, the purpose of the article is to consider the features of the automated aeronautical navigation information processing implementation on the basis of multi-agent technologies. To achieve this goal, the problem-structural methodology of hybrid systems synthesis, which allows us to create self-organizing models, was selected. Each element of which develops, obtaining data and knowledge from other elements. In the research process, a formal definition of the multi-agent system of automatic aeronautical information processing is presented, which involves a set of agents, environment of agent functioning, a set of permissible relations between agents, description of rules for forming a network of agents, a set of individual and joint actions, communication interactions, behavior and actions strategies, a possibility of system evolution. Furthermore, an emphasis is placed on the description of each agent. For this purpose, the authors propose to use four elements: a set of variables, inputs and outputs, an autonomous technique that performs appropriate changes over a set of variables. As agents, the paper comes up with the idea to use the following: Pilots Notification Agent, Preflight Information Bulletin Agent, Data Generation Agent, Aviation Processes Agent, Aviation Database Generation Agent, Aeronautical Maps Creation Agent, Aeronautical Data Set Export/Import Agent, Publications and References Agent. In addition, the article presents the multi-agent system diagram of automated aeronautical information processing and describes in detail processing an application in the agent using the mathematical expression. The results, obtained in the course of investigations, can be used to improve the effectiveness of the analytical component in the structure of the system to form the direct and reverse coordination relationship while solving aerial navigation problems.Прогресс в развитии средств вычислительной техники обеспечивает возможность решать все более широкий класс задач с помощью программных систем, к числу таких задач относится задача автоматической обработки аэронавигационной информации. Это обусловливает необходимость использования новых подходов к проектированию и разработке таких систем. Один из этих подходов основан на применении идеи коллективной деятельности совокупности агентов – многоагентных технологий.

Big Five Technologies in Aeronautical Engineering Education: Scoping Review

The constant demands that technology creates in aerospace engineering also influence education. The identification of the technologies with practical application in aerospace engineering is of current interest to decision makers in both universities and industry. A social network approach enhances this scoping review of the research literature to identify the main topics using the Big Five technologies in aerospace engineering education. The conceptual structure of the dataset (n=447) was analyzed from different approaches: at macro-level, a comparative of the digital technology identified by cluster analysis with the number of co-words established in 3 and 8 and, a keyword central structure (n=8) at micro-level. The articles were categorized by the type of digital technology and, those related to the educational context (n=86) were co-word analyzed to study the relationships between basic and applied research. A total of 18 selected studies were analyzed from a design-based research approach. Findings reveal that Big Data, IoT (2002-2008) and, cloud computing (2010-) were initially applied in the aerospace engineering field. Only Cloud computing (2012) and, Big Data (2017) were transferred towards more educational research. Cloud computer appears related to collaborative work and classroom education. Big data is related to computer-aided design in engineering education. Only Web 2.0 (n=3) is used in the teaching of aeronautical engineering, without any interaction identified in the basic research. Most of the selected studies addressed the undergraduates students and the instructional approach strategy with the result of the potential for improved student learning

Barriers to the adoption of digital twin in the construction industry : a literature review

Digital twin (DT) has gained significant recognition among researchers due to its potential across industries. With the prime goal of solving numerous challenges confronting the construction industry (CI), DT in recent years has witnessed several applications in the CI. Hence, researchers have been advocating for DT adoption to tackle the challenges of the CI. Notwithstanding, a distinguishable set of barriers that oppose the adoption of DT in the CI has not been determined. Therefore, this paper identifies the barriers and incorporates them into a classified framework to enhance the roadmap for adopting DT in the CI. This research conducts an extensive review of the literature and analyses the barriers whilst integrating the science mapping technique. Using Scopus, ScienceDirect, and Web of Science databases, 154 related bibliographic records were identified and analysed using science mapping, while 40 carefully selected relevant publications were systematically reviewed. From the review, the top five barriers identified include low level of knowledge, low level of technology acceptance, lack of clear DT value propositions, project complexities, and static nature of building data. The results show that the UK, China, the USA, and Germany are the countries spearheading the DT adoption in the CI, while only a small number of institutions from Australia, the UK, Algeria, and Greece have established institutional collaborations for DT research. A conceptual framework was developed on the basis of 30 identified barriers to support the DT adoption roadmap. The main categories of the framework comprise stakeholder-oriented, industryrelated, construction-enterprise-related, and technology-related barriers. The identified barriers and the framework will guide and broaden the knowledge of DT, which is critical for successful adoption in the construction industry
