This paper discusses the problem of choosing the best combination of deadlock-free routes of the Up/Down routing algorithm in the framework of the SANDS software. The software is designed specifically for design and simulation of SpaceWire on-board networks. The second component of SANDS allows you to set deadlock-free routes for information flows and select a configuration to present to the user. The document not only sets out the tasks and problems of this area, but also provides an overview of various solutions. In addition, an algorithm is presented that allows you to choose the best combination of deadlock-free routes. Alternative directions for further research are also indicated.

Issues related to the use of mathematical modeling in the process of making management decisions at a sea container terminal have been looked at. A brief overview of generally accepted approaches to the choice of a mathematical apparatus for describing the subtasks of the technological process of terminal cargo handling has been given. The stages of developing a mathematical model based on the author’s methodology for analyzing technological processes for processing import bound cargo traffic at a functioning container terminal have been described in detail. As an example, the process of developing a discrete-event simulation model for processing an import bound container flow arriving at a sea terminal in the MATLAB environment has been considered.

To reduce the total mass and increase the payload, it is proposed to consider the possibility of using wireless sensors on board modern aircraft. A wireless pressure sensor has been selected, an electromagnetic compatibility analysis has been carried out, an optimal standard of wireless data transmission has been proposed, and the element base has been selected for the implementation of the wireless pressure measurement process. The use of wireless technologies on board, according to the authors of the article, will significantly reduce the overall mass, improve reliability, maintainability and the possibility of further upgrading systems as a whole.

Accelerated aging processes occurring in chips manufactured according to fine design rules using ASIC technology lead to the occurrence of recoverable and unrecoverable faults in them during operation. Various mechanisms for fault mitigation are used to ensure the correct functioning of the SoC. The overhead costs (area and energy consumption) for the implementation of these mechanisms are different. The time required to detect an fault and restore the correct operation of the system is also different. As a rule, there are strict limits on the time of fault detection and recovery of the correct operation of the system and on the allowable overhead costs (area and power consumption). These restrictions can be especially severe for aerospace systems, for systems with hard real time requirements. However, the implementation of mechanisms of quickly detecting of faults lead essential hardware overheads. This paper discusses a way to eliminate this contradiction by preventing the consequences of the propagation of faults in individual components throughout the system. This approach can significantly reduce the time to restore the correct operation of the system. The paper discusses methods that allow preventing the propagation of the consequences of faults, an example of their application is given.
