Ship damage control evaluation is based on the ability of its technical means (ship systems) to withstand combat damage and emergency, ensure combat mission accomplishment and prevent its crash. Estimated functional dependency graph (EFDG) is a mathematical model based on structured-logical schemes of ship system operation performance dependence on the state of the elements of these systems. The graph is designed to estimate ship damage control in combat and operational damages of ship systems. This model logically formally reflects functional dependencies between functionally significant elements of various level of ship system equipment aggregation as they perform functionally independent operations. External simulation conditions on EFDG are set by equipment failure models caused by combat and operational damages. The article proposes including in EFDG the nodes of a ship sections (rooms) status with arcs reflecting equipment placement according to the electronic model of the ship. For a slight increase in model dimensionality, this significantly reduces the total number of original data and the amount of considered variants. Such approach allows performing an effective computational analysis of ship damage control for a single model, when this ship damage control is provided by its systems regardless of equipment failure causes. Thus, analysis computational efficiency allows extending the spatial and functional variability of modeling to determine a ship project with the best damage control assessment.

Regulations and state standards are the main documents for regulating development of secured software automated systems. However, it has been a while since their adoption, and a software development technology is upgrading fast. In particular, the classical software development waterfall model, which was taken as a basis for these state standards and had been popular for many years, is recently found to be ineffective due to the lack of flexibility in formal development management. Lack of a development process flexibility leads to an inability to respond to emerging changes of system requirements and may lead to nonfulfillment of requirements specifications. The hybrid development method that combines the advantages of classical approach and modern flexible methods can solve the contradiction between a high technological level of modern automated systems development and outdated requirements of governing documents. The integration of modern flexible design techniques led to appearing of combination development models. At the stages of a waterfall model of software development life cycle they are of great interest both from the scientific point of view (to improve methodological approaches to software development), and practical (for high-quality software that corresponds to the requirements). The article describes some features of introduction of flexible development methods of special purpose functional software. They were identified by the experts of the Research Institute Centerprogramsystem when working on development projects. These features include requirements formation and management including tracing and prioritization, planning and tracking a work progress. The authors consider a number of differences between these types of activities in the development of special purpose software executed in accordance with state standards and a classic waterfall development method. They suggest solutions for organizing a hybrid process that combines the advantages of waterfall and flexible methods of special purposes functional software development and ensures an appropriate implementation according to government standards.

3. Problems of network traffic statistics processing to detect intrusion in existing information systems [№1 за 2016 год]

The article focuses on the problems of collecting and analyzing network traffic statistics to detect intrusion in information systems. Network traffic statistics is considered at the IP Packets flow level. The article considers two possible approaches to collecting such network traffic statistics. They are: collecting statistics at network key points and collecting statistics directly at network nodes. The author compares these approaches in the context of an intrusion detection system implementation into existing information systems. He also shows that the approach to collecting statistics at the key points of network depends on a network topology, while the approach collecting statistics directly on network nodes does not. The paper demonstrates that generation of summary network statistics for both approaches requires a resource-intensive operation (flow deduplication). It makes it necessary to use high-performance equipment. In the case of statistics collection directly at network nodes the author suggests a method for significant reducing of requirements to computing resources to form network summary statistics. This method eliminates the need for deduplication by monitoring network traffic only in one direction at all network nodes and external data links. The paper justifies that the incoming network traffic is effective for this purpose. It is shown that this method allows detecting several types of intrusion in local area networks both from external intruders and insiders without many resources. Cases of illegal network connections are also considered.

Based on analyzing types and content of the Navy combat operations the article justifies the structure of hardware and software tactical simulators for training combat units in ship command posts, submarines, homogeneous and heterogeneous naval tactical groups. The composition and structure of tactical training complex hardware should reflect the structure of real naval command posts. It should also adjust to real ships projects and a manning chart of combat units, command posts and control posts with their workstations. The content of combat actions and naval combat define the requirements for special software of simulators. Special software of tactical training complexes is a set of models of resources, objects, the environment, combat actions, training information models of workstations and trainers’ software.

Flight crew training using flight simulators is essential in order to ensure safe operation of aircraft and helicopters, and the effective implementation of their tasks. Flight simulators are particularly valuable in military aviation as they allow simulating a real combat situation with no restrictions. This is very difficult to simulate in a peaceful time. The article discusses general theoretical issues related to feasibility and development of tactical aircraft system trainers for naval aviation. These simulators are designed for aircrew tactical training so that a crew could use aircraft systems independently and in cooperation with other forces in a unified information-modeling environment. Exercises are carried out at training complex using a method of “virtual” tactical exercises both as unilateral using “computer power” and as “dueling situations”. Weapon simulators and military equipment are in a modeling system, which ensures their operation in one information field. It allows soldiers to act as they would act in real combat conditions. The article considers possible structural schemes of tactical simulators for similar and different types of aircraft systems.

8. Development of typical scenarios of interactive training sessions using new electronic training aids [№1 за 2016 год]
Author: Shustova N.А.

The article is devoted to development of scenarios for computer training programs. Classes that use these programs should have a certain structure. A script for a computer training program is a complicated methodically verified program consisting of three interconnected parts called scores. One score is for a teacher, two others are for students. Each score is constructed according to the structure of a training session and has its own content. A script is divided on scores due to methodical recommendations for trainings and psycho-physiological factors of each participant of a learning process (a teacher and a student). At the same time it is important to comply with the principle of necessity and residual feed of information for a student. Development of a script in such triune form will make computer training sessions more effective.

The article considers an approach to providing ship positioning in commission using automatic identification systems (AIS) with the assessment of the possibility to increase the accuracy of designated position retention when implementing a centralized measurement method. It also considers an approach to developing the structure of a ship automated control system that provides automated control of the ship during joint maneuvers. The approaches are based on the fact that currently it is possible to determine a ship's place continuously and accurately according to satellite radio navigation systems. This provides an efficient navigation support for activities of forces through automated processing and providing navigation data to a user. At the same time, capacity and high-speed data exchange is an important issue in activities of forces. It is essential in the process of managing the Navy forces and means in a rapidly changing environment and increasing in information flows. The practice of the Navy demonstrated the need to create a remote control system for tactical objects. It should solve the problems of determining geographical coordinates of its units and providing these data for users with a possibility to broadcast data including a space segment when a direct link is absent. The use of AIS in vessel traffic management systems operation showed significant advantages that are associated with the defini-tion of a place and motion parameters of maritime objects and ensuring their safe movement without collision. An AIS can be used as a prototype of a ship automated control system.

The article describes calculation methods of ship navigational safety parameters and indicators. It shows that the method implemented in navigational tables MT-2000 and the Instruction for navigation equipment INO-2000 is outdated. It contains methodological inaccuracies and has low efficiency. Such shortcomings are typical for ship navigation in general. The authors suggested developing the Rules of solving navigation probabilistic problems without marked discrepancies. They also suggested creating an integrated textbook, which should contain methods for solving navigation probability problems and cover sections of several disciplines to further algorithmization of rules for their machine implementation.
