Abstract

During the long-term operation, anti-aircraft missile weapons are characterized by the technical condition and level of reliability change influeincing the efficiency on the intended use. The article presents a model of surface-to-air missile system (SAMS) reliability during long-term operation, which contains a set of models, namely: a model of operation of ground combat assets (GCA) of SAMS according to the typical cyclogram of intended use (TCIU); a reliability dynamics model of SAMS GCA in the established system of maintenance and repair (SMR) and a reliability dynamics model of surface-to-air missiles (SAM) during extended usage. It is expedient to use the developed model at substantiation of requirements to the indicators of SAMS and SAM reliability for their development or modernization; when developing SAMS repair plans in terms of determining the time of SAMS GCA and (or) SAM repairing time and when developing methods for assessing the effectiveness of SAMS taking into account the duration of SAMS GCA and SAMS usage.

Highlights

Modern surface-to-air missile system (SAMS) are designed for long-term operation
In accordance with [14, 15] the SAMS operational and tactical indicator (OTI) Keff [13] represents the ratio of mathematical expectation (ME) of the number of targets destroyed by SAMS, taking into account its technical condition and reliability, to the nominal value of ME, provided that SAMS is operational at the beginning of combat operations and does not fail in the process of functioning during a long-term operation
Model of operation of SAMS ground combat assets (GCA) according to typical cyclogram of intended use (TCIU) describes possible operating modes in the operating interval considered in relation to the moment te – calendar time in service

Summary

Introduction

Modern SAMSs are designed for long-term operation. According to the SAMSs analysis used in many countries, it is established that the duration of their life cycle is. It is necessary to solve a set of tasks related to the assessment of the impact of SAMS GCA and SAM components on the efficiency of SAMS operation, namely substantiation of requirements to its GCA reliability indicators and reliability indicators and assigned SAM indicators. In this regard, it is important to develop a model of reliability of SAMS during long-term operation to assess the effectiveness of SAMS
