Fuzzy Logic in Selection of Maritime Search and Rescue Units

The article discusses methods of ships assessment when determining their suitability for search and rescue action (SAR) at sea. Selection of the most preferable ships is one of the action planning elements. Due to various construction and equipment the civilian ships can only perform rescue task to a certain degree. According to the Multi-Criteria Decision Analysis (MCDA), many parameters and data have to be compared in order to create a ranking of vessels ordered according to the coordinator’s preferences. When data are missing, incomplete or uncertain, a similar effect can be obtained using fuzzy logic. The author discussed the nature of the criteria, evaluation methods and presented a simulation of a ship study using fuzzy logic. The author developed fuzzy rules and presented the principle of operation of the controller. The article deals with the main principles of a decision support system (DSS) for the selection of ships in SAR operations.

The technological design of all stages of development from a sketch to a 3D model is described. A distinctive feature of the proposed design is its versatility: the ability to use both a trolley and a trailer for small-sized equipment, for example, an ATV, which serves as an addition to existing weapons and contributes to increasing the effectiveness of extinguishing landscape fi res and conducting reconnaissance and search operations.

A Web-Based Decision Support Systems Framework for Ill-Structured Decision Situations

Decisions and actions in an ill-structured situation often include high-time constraints, lack of information, and poor cognitive efforts. Obtaining the necessary information through an information systems tool is supposed to be the best solution in such situations. To expose the decision situation, this study has taken the fire and civil defense service as the field of study. In exploring the required information resources, elements of the system architecture, and suitability of the proposed system in the current field, this study has resorted to the qualitative approach. To assess the dependability and performance of the systems, this study has used the RAS metrics and a black-box test. The result showed that the reliability stood within 62.70–70.00%, and its availability stood at 99.00% with a downtime of 3.65 days/year from a three-month study. As per the black-box test with standard 4G network connection, the system takes an average loading time of 1.00s for alphanumeric contents, 3.50s for images and graphics, and 5.50s for loading maps and navigations. This research evidenced that, the local emergency response and rescue units in developing countries like Bangladesh might want to use a well-designed response support system for improved acquisition, dissemination, and utilization of response information.

Determination the rational locations of territorial emergency response teams in the area of possible emergency situations of natural and technogenic nature

Due to frequent emergency cases at hazardous production facilities, which can lead to an environmental disaster, material and social damage, the issue of using the rational locations of territorial emergency response teams in the area of responsibility is the most relevant. The greatest weight if it is necessary to determine the rational place for the permanent deployment of territorial emergency rescue units created by the state authorities of the subject of the Russian Federation. Due to the lack of guidance documents and methodological recommendations for determining the permanent location of territorial emergency rescue units, this task was solved in each constituent entity of the Russian Federation in its own way and with a significant degree of subjectivity. It is proposed to use an algorithm for determining the permanent location of the rescue formation in the area of responsibility based on the probability of calling the formation to incidents, accidents and emergencies.

Use of modern psychotraining technologies in the framework of the recovery period of extreme detail profile specialists

The article considers the problem of the recovery period of activity of specialists of risky professions after their performance of tasks on purpose. In solving this problem, it was suggested to use socio-psychological training.

Detection of a predefined acoustic pattern by a measurement system on a drone and its application to search for a missing man in an underground mine

Due to the very difficult working conditions and a certain number of hazards that do not occur in other industries, the operation of rescue units in underground mines is necessary. The area of exploitation is usually very large, thus determining the location of a person, which may be in need due to the accident, is not an easy task. As the time for reaching such a person is crucial, there is a strong need for a solution that would provide a quick establishment of the victims’ location. Moreover, conducting a rescue mission is always associated with risk exposure for rescuers’ life and health. Thus, in this paper, we propose a solution based on an unmanned aerial vehicle (UAV) for a predefined acoustic pattern detection to support rescue units in human location assessment in the underground mine. The presented method is based on measuring the dissimilarity between the subsequent short-time power spectra and the referential spectrum characterizing the UAV’s ego-noise. This relatively general and data-driven approach is applied both to generated narrowband harmonic patterns and to the human voice. As the analyzed signals of interest are of specific frequency content they can be selected from the background noise with the use of band-pass filtering.

Implementation of subject-professional training of University cadets of higher educational institutions of the Ministry of Emergency Situations

The article deals with topical issues of improving the level of training of cadets of educational institutions of the State Fire Service of the EMERCOM of Russia for professional activities in the field of fire fighting. The application of the implemented disciplinary approach, which assumes a time-dispersed nature of studying various disciplines in the field of fire fighting, does not allow you to get concentrated knowledge, skills and sufficient experience in performing combat operations to extinguish fires, which affects the professional readiness of graduates for practical activities. The purpose of the study is to form a subject-professional approach that will allow, through the optional hours of the main educational program on the basis of previously formed skills and abilities, to implement through training courses concentrated training in the field of fire fighting to improve the professional readiness of graduates. To increase the level of professional readiness of graduates, the author studied the experience of practical training in the field of fire fighting, analyzed the activities of fire and rescue units in extinguishing, studied normative documents and scientific works in the subject area, has developed a subject-professional approach for concentrated training, as well as the subject-matter and content of training courses, has formed an evaluation tool for students. The author proposes to implement a subject-professional approach through the development and implementation of basic, special and additional training courses, for the formation of which modular, competence-based and contextual approaches were used, aimed at maximum professional orientation of training, courses that allow to increase the competence of graduates in the field of fire fighting. The author also proposes to implement the subjects of the training courses through practical classes based on the game forms of training that increase the educational and professional motivation of students. The author concludes that in order to increase the effectiveness and further development of the subject-professional approach, it is necessary to expand the subjects of training courses and improve them, taking into account the changing regulatory framework, the experience of fire and rescue units in fires, the development of fire extinguishing tactics and the introduction of new models of fire equipment and fire-technical equipment.

ANALYSIS OF RISK AND NO-RISK INTERVENTIONS BY MEMBERS OF FIRE AND RESCUE UNITS UNDER MULTI-RISK CONDITIONS

The issue of occupational safety and health of the members of fire and rescue units has been continuously studied by numerous authors. Their interest stems from the constant need to improve the methods and procedures of occupational safety and health assessments for fire and rescue unit members, all for the purpose of preventing injuries, primarily the fatal ones. The fact that a certain number of high-risk situations in which firefighters avoid an injury or death remain unreported poses a serious threat to the firefighters’ safety. This threat has been unjustifiably neglected and it is what motivated the research discussed in this paper, which reveals the results of three discriminant analyses.

Interdisciplinary Distance Learning Workshop for IT Students

The purpose of the study. The purpose of research is to substantiate and develop a multifunctional training complex for preparing cadets to conduct emergency rescue operations and fire-fighting by the usage of virtual reality technology. The relevance and necessity of developing a training complex are due to the professional activities of fire-fighters, related to the protection and rescue of citizens and the state from fires and the peculiarities of the educational process being implemented. The problem of effective formation of professional competencies in the field of fire-fighting is caused by the limited training ground base of universities, which does not allow training at various residential, social, industrial, transport and other functional facilities, that requires their replacement with virtual analogues. In addition, the limited budget of training time and a large number of cadets studying at the university, who must have the skills and abilities to manage fire and rescue units, organize fire extinguishing and interact with other emergency services, require the introduction of digital technologies to increase the intensification of the educational process and expand its capabilities.Materials and methods. To perform research tasks, methods of scientific and pedagogical study were used, which included the analysis and synthesis of information in the field of creating and applying digital virtual reality for educational purposes, the activities of fire and rescue units during fire-fighting and the requirements of regulatory legal acts for the performance of their professional tasks. Methods of modeling, contextual, game and reflexive training were used to form methods of preparing fire-fighters in virtual reality, recreating the professional environment.Results. The research of the activities of professional fire-fighters, the peculiarities of the educational process implemented at the universities of EMERCOM of Russia has revealed deficiencies in the training of cadets for activities in the field of organizing and conducting rescue operations and fire-fighting. According to the investigation of the adaptation and usage of digital learning technologies to improve the professional competencies of graduates in the field of fire-fighting, the application of virtual reality technology was proposed that allows to simulate a professional environment and to organize it in both individual and group practical preparation of cadets to professional tasks on a variety of residential, social, industrial, transport and other functionalities in conditions of simulating various scenarios of the occurrence and development of fires. To organize the training of cadets, the requirements for the specification and technical characteristics of the equipment, the project of the training ground for the organization of virtual learning (which was physically implemented at the Ivanovo Fire and Rescue Academy of State Fire-Fighting Service of EMERCOM of Russia), system and applied software, basic objects, models and scenarios of fire spreading on them, a system for evaluating the tasks performed by the trainees were developed in common with closed joint-stock company “Institute of Telecommunications” (St. Petersburg, Russia). Conclusion. The result of the research is the first physical prototype of a multifunctional training complex to prepare cadets for emergency rescue operations and fire-fighting, where it is planned to conduct a pilot operation stage during 2021, expand the list of objects and scenarios for the development of fires and subsequently introduce it into the educational process. The technological and methodological experience gained in the process of designing, implementing and operating a multifunctional training complex is planned to be extended by scaling it to other universities of the EMERCOM of Russia, which will create and unify a single system of practical training of cadets in the field of fire-fighting, using virtual reality technology.
