“…Сформулированный в [1] подход к управлению избыточностью отказоустойчивых систем, более подробно прорабатываемый в [2,14,15] для авиационных бортовых реализаций, подра-зумевает использование так называемых супервизоров конфигураций (СК) -программных объектов, каждый из которых соотнесен с определенной конфигурацией и выполняет все процедуры подготовки, выбора и реализации «своей» конфигурации. В работе [2] − модуль арбитража осуществляет выбор предпочтительной конфигурации в сложившихся условиях функционирования комплекса путем сравнения интегральных ИГ и ПФЭ конфигураций по определенным правилам, в результате чего осуществляет выбор предпочтительной для реализации конфигурации;…”

The article solves the task of an operational choice of the most suitable conditions for the functioning of the configuration of the components of a redundant onboard equipment in the interests at the same time as ensuring the high fault tolerance of the complex and the achievement of its other performance and technical characteristics. The basis of the redundancy management system is the program subjects in terms of the number of well-developed competitive configurations of heterogeneous and non-communicable equipment complex, called configuration supervisors. The choice of preferred configuration is proposed by performing a multi-level arbitration, which includes the comprising two phases of the pair arbitrator of the computers of the complex and the paired arbitration of configuration supervisors. To ensure the reliability of the competition in the conditions of possible collisions related to the unreliability of information parcels in a pair or with failures of arbitration modules, procedures have been introduced consisting in mutual cross-checking of information parcels between the supervisors of the pair. In case of conflicts when choosing a preference, mutual replacement of the inputs of the arbitration modules and re-evaluation of preferences is provided. The means of both types of arbitration are invited to include in each configuration supervisor, which ensures its self-sufficiency with participation in a competitive selection. The first part of the article is devoted to the paired arbitration of configuration supervisors that implements mutually crossanalysis of readiness indices and indicators of the functional efficiency of configurations combined into a pair. The brute force organized by any way allows you to identify the preferred configuration for subsequent implementation. Two options for paired arbitration of configurations of various complexity and efficiency with binary estimates of preferences (simplified and complete), as well as an arbitration option with triplex preference estimates are also proposed and analyzed. The results of the comparison of the arbitration options are presented, which is selected by the developer based on considerations of guaranteed presence or restrictions of the system design. A methodological example is given illustrating the possibilities of paired arbitration of configurations and its features of a practical nature.

The article solves the problem of operative selection of the redundant onboard equipment complex components configuration of the suitable in the current operating conditionаs in the interests of ensuring high fault tolerance of the complex, as well as achieving other operational and technical characteristics. The basis of the redundancy management system of the complex consists of configuration supervisors — as program subjects according to the number of its competitive configurations of heterogeneous and nonuniform equipment worked out in advance. The choice of the preferred configuration is proposed to be carried out by performing multi-level arbitration, which includes two phases of paired arbitration of computers and paired arbitration of configuration. It is proposed to include the means of both types of arbitration in each configuration supervisor, which ensures its self-sufficiency when participating in a competitive selection. The second part of the article is devoted to the computer’s arbitration for the implementation of redundancy management functions. The approach is applicable to a computing environment with many comparable computing devices and contains 2 phases. In the first phase, a preliminary selection of a competing pair of computers — as applicants for the implementation of redundancy management functions in them is carried out. In the break between the phases, the pair computers implement the procedures for pair arbitration of configurations given in the first part of the article. In the second phase, the final choice of the α-computer is made, in which the supervisor who won the arbitration will be implemented. In order to achieve the maximum possible centralization of selection procedures and, as a consequence, the exclusion of "bottlenecks" in terms of reliability of places, additionally proposed: the organization of secure data exchange between computers based on distributed registry technology; the procedure of paired arbitration of computers, consisting in mutual cross-validation of dominant supervisors of a pre-allocated pair by comparing preference matrices, including information parcels of arbitration objects. A methodological example that demonstrates the features of the system functioning in the conditions of computers degradation is given. The proposed approach can be used to solve the problems of reconfiguration control of heterogeneous computing facilities of technical objects on-board equipment complexes.
