У процесі вентилювання з приміщення утилізується не тільки відпрацьоване повітря, але й частина теплової енергії. Узимку це призводить до збільшення рахунків на енергоресурси. Скоротити невиправдані витрати, не на шкоду повітрообміну, дасть змогу рекуперація тепла в системах вентиляції централізованого і локального типу. Для регенерації теплової енергії використовуються різні види теплообмінників – рекуператори.; EN: The article deals with the problems of calculation and selection of recuperators, which are installed in the ventilation system of buildings of public catering establishments. In article razganata problem rozrahunkiv wyboru heat exchangers, that ustanovlyuvalysya in the ventilation system Budivel zakladu gromadska harchuvannya In the process of ventilation from the room is utilized not only waste air but also a portion of the thermal energy. In winter, this leads to an increase in energy bills. Heat recovery in centralized and local ventilation systems will allow to reduce unnecessary costs, not to the detriment of air exchange. Different types of heat exchangers are used for heat energy recovery. The article considers the problems of analysis and selection of heat exchangers that are installed in the ventilation system of buildings of public catering establishments working Principle of any heat exchanger supply and exhaust units is as follows. It provides heat transfer (in some models – and cold exchange, as well as moisture exchange) between the flows of supply and exhaust air. The process of heat exchange can occur continuously - through the walls of the heat exchanger, with the help of freon or intermediate coolant. The heat exchange can be periodic, as in the rotary and chamber recuperator. As a result, the exhaust air emitted is cooled, thus heating the fresh supply air. The process of cold exchange in some models of recuperators takes place in the warm season and allows you to reduce energy consumption for air conditioning systems due to some cooling supplied to the room supply air. Moisture exchange is between the streams of exhaust and supply air, allowing you to maintain a comfortable room for human humidity year-round, without the use of any additional devices – humidifiers and others.

Проаналізовано існуючі технології роботи пасажирських станцій. Запропоновано варіанти раціоналізації часу обслуговування пасажирів шляхом удосконалення оперативного управління роботою вокзалу пасажирської станції на основі застосування елементів інтелектуальних технологій та методів імітаційного моделювання. Розроблено імітаційну модель роботи вокзалу станції та оптимізаційну модель з пропуску пасажиропотоку.; EN: In the article the question of improving the quality of passenger service in the operation of high-speed traffic. The existing technology of passenger and passenger technical stations. Proposed options for streamlining time of passenger service by improving the operational management of the work station is a passenger station on the basis of application of intellectual technologies and simulation methods. Developed a simulation model of the station and the optimization model via the crossing traffic flow. When you create a model, in which passengers arrive at railway station and move to the departure gate, the logic model set with blocks of AnyLogic pedestrian library. Pedestrian library AnyLogic is a library simulation of pedestrian traffic in the physical space. It allows you to model buildings, which have accumulated large numbers of people (metro stations, railway stations, airports, shopping malls, stadiums, museums, etc.). The purpose of the simulation model is to reproduce the behavior of the system under study based on the results of the analysis of the most significant relationships between its elements. The statistics are collected directly at the station at the time of the greatest load. To synchronize the collected data it is necessary to collect data at one time from all directions of passenger traffic. Passengers are divided into incoming and outgoing (suburban and long-distance passenger traffic). In turn, incoming passengers are sent with pre-purchased tickets, which go to cash (suburban and long distance), which are in a state of waiting. Prior to the departure, passengers who arrived and follow the exit from the station, passengers in anticipation of a transfer, or departure of the train, passengers who go to the cash desk. In order to ensure a comfortable stay of passengers in the railway station, accelerate the service of registration of transport documents, and exclude delays, it is proposed to monitor cash services promptly, by introducing a decision support system to the automated workplace of the main cashier, which will allow adding additional resources from the coffee service for the period of overload system of service.

Запропонований основний принцип ефективного логістичного управління – необхідної різноманітності. Пропонуємо логістичні моделі освоєння пасажиропотоків швидкісним залізничним транспортом та корегування плану формування пасажирських поїздів. Вивчення логістики прогнозування пасажиропотоків швидкісних залізничних перевезень вказало на той факт, що у логістичній моделі вибору пасажирами варіантів реалізації запланованих поїздок бажано використовувати одночасно соціально-економічні фактори і рівень тарифів на залізничному транспорті.; EN: The research of the technology of functioning of the logistic situation model of transport service of the population is conducted, provided that the participation of high-speed rail transport is involved. The basic principle of effective logistic control is established - the necessary diversity. The logistic models of development of passenger traffic by high-speed railway and the correction of the plan for the formation of passenger trains were constructed. The study of logistics of the forecasting of passenger traffic of high-speed rail transportation pointed to the fact that in the logistic model of choice of passengers for the implementation of planned trips it is necessary to use simultaneously socio-economic factors and the level of tariffs on rail transport. It is established that the real choice of a passenger for a variant of a trip is influenced not so much by the level of tariffs for transport services, as the ratio between passenger tariffs and incomes. Since the average passenger travels only 1-2 trips in a year, the trip planning is determined by the income level not in the particular month during which the trip was made, but by the average income over the long previous period (for example, one year). Thus, in the task of logistic modeling, instead of the indicators of average per capita cash income, the minimum consumer budget and the initial tariff levels, it is necessary to use factors calculated on their basis, such as the real level of monetary incomes and the real level of tariffs in different categories of high-speed train cars. For checking the correctness of the choice of factors and assessing their impact on the quality of the logistic model, preliminary studies of the results of calculation based on the long-distance passenger traffic from the above factors were carried out. The accuracy of the simulation was determined by the degree of approaching values of passenger traffic, calculated using the model, to real passenger traffic data. факторы и уровень тарифов на железнодорожном транспорте.

При плануванні відправлення поїздів необхідно враховувати такі чинники, як середні тарифи, густота руху по дільницях, нерівномірність прибуття по періодах доби, економічні показники. Планування відправлення поїздів може варіюватися в залежності від інтенсивності руху по днях тижня і періодах доби. При моделюванні враховуються обмеження з пропускної спроможності пасажирських і пасажирських технічних станцій, а також задоволення попиту пасажирів.; EN: Improving the competitiveness of rail transport in the field of passenger transport is possible by increasing the speed of movement of passenger transport and the quality of services provided. With the growth of mobility of population, high-speed passenger transport should constantly develop; expand the boundaries of the high-speed passenger trains. However, in recent years there has been a decrease of the number of passengers carried by the railroad with the transition to alternative means of transport: air and automobile transport. Aviation transport attracts with flexibility of tariffs and speed of delivery and automobile transport attracts with the intensity of bus departure and the possibility to choose the convenient time of departure and arrival at the final destination. The article considers the issue of planning the departure of passenger trains, taking into account the minimization of parking time and the cost of organizing the traffic. Planning of transportation is fundamental in the organization of transport and the foundation for maximizing the overall profit of the railway company. The complexity of planning is due to the need to build schedules corresponding to the variable demand of passengers. Making accurate forecasts that take into account reliable information about demands of the passengers according to the seasons of the year, months and days of the week is difficult to formalize. While planning the departure of trains, it is necessary to take into account such factors as average tariffs, traffic density on sections, uneven arrival in different periods of the day, economic indicators. Planning of departure of trains may vary depending on the intensity of movement by days of the week and periods of the day. The modeling takes into account restrictions of the capacity of passenger and passenger technical stations, as well as meeting the demands of passengers. The results of calculations showed the uneven departure of trains with pronounced "peak" periods in the morning and evening hours, which may limit the capacity of passenger stations. Simultaneous arrival of trains of the same category (high-speed) results in additional loading of the passenger compartment of technical stations.
