Mission-Oriented Missile Equipment Support System Modeling: Considering the Failure and Health State

Missile equipment support system is a complex system involving mission profile, operating environment, support personnel, resource scheduling, and other factors, and most of the equipment failures are a process of continuous evolution over time. Based on the characteristics of equipment functions or performance parameters and current detection methods, only part of equipment health degradation trend can be monitored. Therefore, it is necessary to carry out the support system simulation considering the equipment failure and health state comprehensively. In this paper, a mission-oriented modeling framework of missile equipment support system based on agent is proposed. Agents of equipment, support, management, and environment are abstracted. The behavior logic, information transmission link, and interaction mechanism among agents are explained. The failure occurrence handling mechanism and health state degradation handling mechanism are determined. The equipment recovery behavior model, including equipment health state control model, corrective maintenance behavior model, and system reconstruction behavior model, are constructed, and the simulation process and implementation method are explained. Finally, a certain type of missile equipment is taken as an example for simulation. The results show that the mean time between failures can be extended and the times of corrective maintenance can be reduced by maintenance support with integrated consideration of equipment failure and health deterioration. In addition, the simulation results show the variation trend of equipment availability, which can lay a solid foundation for the optimization design of equipment support resources in the future, so as to improve the availability of equipment in the whole life cycle.

METHOD OF RELIABILITY IMPROVEMENT OF AIR-TO-SURFACE MISSILES CONTROL EQUIPMENT

The article analyzes the current state of the fleet of guided air means of destruction (missiles), the problems of repair and extension of the resource. The article substantiates the need for the transition of guided air missile of the "air-to-surface" class to operation according to the technical condition. The shortcomings of the existing inspection system for the technical condition of guided air weapon are shown. For the existing inspection system of technical operation of guided air weapon, one of the areas that will solve the problem of maintaining the combat readiness of aircraft is the transition to the operation of guided air weapon in technical condition.
 It is shown that the transition of guided air missiles to operation according to the technical condition and modernization of unguided air missiles involves strengthening the role of operations to measure and control their parameters and characteristics in order to determine the actual technical condition and make informed decisions about their further operation.
 Peculiarities of appearance of the Type 1 and Type 2 errors during control of a technical condition of aviation armament are presented. A method of increasing the reliability of air-to-surface missile control equipment by conducting control checks in the inter-check interval is proposed. The fundamental difference between the proposed information-redundant model of operation of guided air missiles and the classic model is the introduction into the system of operation a new diagnostic operation - an intermediate control check. Peculiarities of application of the developed method concerning calculation of both quantity of control checks and their periodicity within an inter-check interval are shown.

ЩОДО ОЦІНЮВАННЯ ВІДПОВІДНОСТІ МАТЕМАТИЧНОЇ МОДЕЛІ БЕЗВІДМОВНОСТІ БОЙОВИХ ЗАСОБІВ ЗЕНІТНИХ РАКЕТНИХ ВІЙСЬК ВИМОГАМ ДО МАТЕМАТИЧНИХ МОДЕЛЕЙ

The article presents a variant of the procedure for assessing the compliance of the mathematical model of the reliability of anti-aircraft missile warfare equipment with the requirements for mathematical models using the example of the Buk self-propelled fire launcher. Parameters affecting change of serviceability of self-propelled fire plant operation in conditions of combat situation are determined. The use of the Weibull distribution allows, by varying the parameter values, to increase the guarantee of the implemented self-propelled fire plant reliability indicators, stated in technical conditions, during its operation in the troops. If necessary, this model can also take into account factors that arise suddenly, for example, taking into account the staffing of the self-propelled fire plant of the anti-aircraft missile regiment to assess the possible (predicted) value of average daily losses, taking into account various measures to reduce the values of the predicted average daily losses. Values calculated using this model react markedly to changes in model parameters, are set within the specified restrictions. In addition, it is possible to determine the time between failures. The accuracy of the results of calculating certain quantities using the mathematical model was estimated by absolute and relative errors. The calculations indicate the relative simplicity of the mathematical model, because it uses simple mathematical methods. The ability to vary the parameters of scale and shape parameters (taking into account aging), the mathematical model of IED failure makes it possible to obtain individual (partial) results obtained using previously used similar models, which emphasizes the evolution of this model. The improved method of mathematical modeling quite adequately reflects the trouble-free operation of the anti-aircraft missile system "Buk" taking into account the conditions of hostilities and meets the requirements for mathematical models. Keywords: probability of failure-free operation, parameters of mathematical model, combat situation, absolute error, time between failures, average daily combat losses.

\u201cAn Eye Turned into a Weapon\u201d: a Philosophical Investigation of Remote Controlled, Automated, and Autonomous Drone Warfare

Military drones (unmanned combat aerial vehicles) combine surveillance technology with missile equipment in a far-reaching way. In this article, I argue that military drones could and should be object for a philosophical investigation, referring in particular on Chamayou’s theory of the drone, who also coined the term “an eye turned into a weapon.” Focusing on issues of human self-understanding, agency, and alterity, I examine the intricate human-technology relations in the context of designing and deploying military drones. For that purpose, I am drawing on the postphenomenological approach developed by Don Ihde in order to systematize the manifold aspects of human-technology relations in a four-level model (embodiment relations, hermeneutic relations, alterity relations, and background relations). This inquiry also includes a critical reflection on the (often hidden) normative implications of this technology. In doing so, I do not intent to offer an exhaustive relational ontology of military drones. I rather aim at providing a framework that is able to capture the core dimensions of this technology and their complex interrelations in a systematic way that has been missing in the philosophical debate so far.

Compared with multiple linear regression, least squares support vector machine and other methods, the results show the effectiveness of the model.
