The article solves the problem of complex substantiation of reliability and maintainability requirements for mobility means of surface-to-air missile (SAM) systems considering hierarchical structure of mentioned systems and appropriate characteristics of their mobility means, minimum configuration of SAM system means for air defense operation and a number of tactical characteristics of operation area. The quantitative characteristics of effectiveness of SAM system mobility means are measured by the coefficient of effectiveness sustainment which is the ratio of initial effect considering reliability and maintainability of mobility means to its value in case of faultless mobility means. The developed mathematical models, which are proposed for further use as a program product, are designed for defining the limit values of such reliability measures as mean range between failures and mean recovery time of combat and technical facilities of SAM system corresponding to given values of coefficient of effectiveness sustainment.
ОПТИМИЗАЦИОННАЯ МОДЕЛЬ КЛАСТЕРИЗАЦИИ ТРАНСПОРТНОЙ РАСПРЕДЕЛИТЕЛЬНОЙ СЕТИ ПРОМЫШЛЕННОГО ПРЕДПРИЯТИЯA.E. Radaev, V.V. Kobzev AN OPTIMIZATION MODEL FOR CLUSTERING A DISTRIBUTED TRANSPORT NETWORK OF AN INDUSTRIAL ENTERPRISEСовременные условия развития отечественных промышленных предприятий обусловливают высокую зна-чимость вопросов минимизации логистических затрат на этапе проектирования соответствующих распредели-тельных сетей. Данное обстоятельство определило целесообразность разработки оптимизационной модели кла-стеризации транспортной распределительной сети промышленных предприятия на базе математической по-становки задачи о разбиении. Разработанная модель обеспечивает определение потребного количества иден-тичных друг другу транспортных средств, необходимого для обслуживания контрагентов-потребителей, в рам-ках рассматриваемой распределительной сети, а также формирование оптимальных маршрутов движения транспорта по критерию минимизации суммарных затрат на перевозку грузов при ограничениях по вместимо-сти транспортных средств и длительности обслуживания потребителей в рамках отдельного маршрута. Исход-ными данными для реализации оптимизационной модели являются характеристики структуры распредели-тельной сети в части состава ее основных элементов (транспортных пунктов) и связей (магистралей) между ними, характеристики транспортных средств в части условно-переменных и условно-постоянных затрат, дли-тельности перемещения по связям транспортной сети и вместимости кузова. Для оценки адекватности разра-ботанной модели была произведена ее реализация на практическом примере при решении задачи маршрутиза-ции мелкопартионных автомобильных перевозок в рамках Санкт-Петербурга и Ленинградской области. Ос-новные этапы ее решения следующие: формирование исходных данных для реализации оптимизационной мо-дели; реализация оптимизационной модели для различных вариантов модели транспортных средств; анализ результатов реализации модели для каждого альтернативного варианта модели транспортного средства; по-строение зависимостей показателей процесса выполнения маршрутов от вместимости используемых автомоби-лей. Результаты анализа полученных зависимостей подтвердили адекватность разработанной оптимизационной модели и, как следствие, ее высокую практическую значимость.

Due to this circumstance, it seems expedient to create an optimization model for clustering the distributed transport network of an industrial enterprise. The created model allows to determine both the required number of identical transport vehicles to serve contractors (consumers) within the examined distribution network and the formation of optimal routes for transport movement according to the criterion of minimizing the total transportation costs with const...
The results of the research published in the article will be useful for logistics specialists who are engaged in the organization of the provision of resources (material and technical means) for the processes of operation and renewal of armament and military equipment (AME). The article discusses existing approaches to logistic support of operations (combat actions) and methodological approaches to assess the effectiveness of its operation. The influence of factors and problematic issues on the creation of a modern logistics system of the Armed Forces of Ukraine is analyzed. The scientific substantiation of determination of indicators of efficiency of delivery of resources in the system of logistic support is offered with the purpose of improvement of functioning of the system of delivery of resources for further consideration during planning of activity. According to the results of the analysis, the urgency of making a quick and correct decision in managing the provision of necessary resources was determined. The dependence of resource efficiency on the type of resources, the intensity of applications for their use, and the capabilities of the system to create and replenish resources have been established. The basic concepts and typical structures of the resource delivery system for working out of the research materials are clarified. Based on the analysis, it was found that the evaluation of the efficiency of the system of maintenance of the processes of operation and restoration of AME resources should be carried out by the results of the evaluation of the efficiency of providing the resources of each type individually and further determination of the system performance indicators as a whole, taking into account the corresponding total costs for providing the resources, which allowed to offer methodological an approach to assessing the effectiveness of operating processes and the renewal of AME resources themselves, which allows to take into account the implemented strategy of replenishment of resources and rationality of the selected transport network in the conditions of both peacetime and fighting.On the basis of the proposed methodological approach, the directions of further researches were determined concerning: determination of the list of initial data for determining the characteristics of the routes of resource delivery; determining the number of characteristics that are being optimized; forming a methodological approach for determining a rational transport network in the logistics system.
The article discusses approaches to ensure the combat work documentation on the combat means of surface-to-air missile systems (complexes) in modern conditions. It focuses attention on the main discrepancies of the existing objective control means of combat work to the requirements of time. A review of existing research and publications on objective control of combat work shows that the existing approaches are mainly focused on organizing objective control at command and control centres and do not take into account the specifics of conducting combat work on combat weapons of surface-to-air missile systems (complexes). That is why the purpose of the article was chosen to substantiate propositions for improving the objective control system of the combat work on combat weapons of surface-to-air missile systems. When developing proposals for improving the objective control system of combat work on combat means of surface-to-air missile systems (complexes), the emphasis is placed on the fact that a promising objective control system of combat work, unlike the existing one, should be based on modern element base, be unified and should record video , audio, combat and technical information circulating in the combat means of surface-to-air missile systems (complexes). The structure of this system, its elements, communication organization is proposed, the expediency of such a construction option is justified. For each element, its functional purpose is indicated and the design direction is advisable. In addition, it was proposed to use this approach in the future for samples of weapons and military equipment (radar stations, command and control stations, combat vehicles) of other troops types.
