Devising a procedure for substantiating the type and volume of redundant structural-functional elements of reconnaissance-firing systems

Abstract

This paper proposes an algorithm for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems, taking into consideration the operational patterns of such systems. Underlying this algorithm is the combination of survivability assessment methods and reliability assessment methods. Such an arrangement aimed to improve the efficiency of the application of these methods and reduce uncertainty in the calculations. The results from calculating an example of the application of a procedure for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems have been analyzed. The analysis of the results shows that the set task is fulfilled, in particular the specified probability of trouble-free functioning of a reconnaissance-firing system, with a combined type of redundancy. Moreover, it implies giving preference to passive redundancy, using active one only to critical elements – individual functional elements of the control subsystem. The advantage of a mixed type of redundancy over a passive redundancy is 28 %. In addition, it has been established that the multiplicity of redundancy, for accepted conditions, should not be lower than 2. A procedure for substantiating the type and volume of redundant structural and functional elements of reconnaissance-firing systems has been devised, taking into consideration the operational patterns of such systems. The specified procedure includes an algorithm, as well as methods for assessing survivability and methods for assessing the reliability of functioning. This procedure was tested for feasibility by considering an example of justifying the type and volume of redundant structural and functional elements of reconnaissance-firing systems that produced an adequate result. The result has been confirmed by the practical application of reconnaissance-firing systems in recent armed conflicts

Improving a procedure for determining the factors that influence the need of higher education institutions for specialists of the highest qualification

“…In general, the approach to determining the relative competence of experts during the aggregation of pairwise comparisons meets the improved approach proposed in [17,18]. Thus, the basic components of the coefficient of relative competence of a member of expert group С is self-evaluation С self , mutual evaluation С mutual , and objective component С objective .…”

“…Thus, the basic components of the coefficient of relative competence of a member of expert group С is self-evaluation С self , mutual evaluation С mutual , and objective component С objective . The general expression is: С=С self (Х 1 С mutual + +Х 2 С objective ), where Х 1 and Х 2 are relative weights of objective and mutual evaluation of competence of the members of the expert group [17,18]. In this case, mutual evaluation is determined as the indirect value of the judgments of all experts С mutual .…”

Devising a procedure for justifying the need for samples of weapons and weapon target assignment when using a reconnaissance firing system

“…Our research involved RFSs of the tactical level, which implied considering up to five targets and five types of weapons [22]. However, it should be noted that the procedure given in this paper could be adapted for other levels of planning, in particular, operational and strategic.…”

Обґрунтування Показників Та Критерію Можливої Живучості Артилерійських Підрозділів Під Час Вогневої Підтримки В Наступальних Діях

“…Постановка проблеми. Практика застосування складних систем військового призначення у ході ведення збройної боротьби, у тому числі артилерійських підрозділів (АП), показує, що проблема забезпечення необхідної ефективності застосування та забезпечення їх живучості має першорядне значення [1][2][3][4][5][6][7][8]. У свою чергу враховуючи, що цикл оновлення засобів ведення збройної боротьби, в тому числі і артилерійських систем, становить не менше 10 років [9][10], нагальним завданням на період до 2030 року є дослідження питань забезпечення живучості без зниження ефективності застосування військових формувань артилерії зі складу систем військового призначення.…”
