The operation model of a complex system changing its functional structure and its instantaneous operation costs during the variable at time operation states and linear programming are proposed to optimize the system operation process in order to get the system total operation cost minimal. The optimization method allowing to find the optimal values of the transient probabilities of the complex system operation process at the particular operation state that minimize the system total operation cost mean value under the assumption that the system conditional operation costs mean values at the particular operation states are fixed or in the safety state subset not worse than the critical safety state are presented. The procedure of finding the optimal mean value of system total operation cost for the fixed operation time or in the safety state subset not worse than the critical safety state are applied to the port oil terminal operation cost minimization.

The model of system operation total costs in the safety state subsets is introduced and the procedure of its operation total cost in the safety state subset not worse than the critical safety state minimization is presented. The model of system safety impacted by operation process is created and the procedure of its safety in the safety state subset not worse than the critical safety state maximization is presented as well. To analyze jointly the system safety and its operation cost optimization, we propose the procedure of determining the optimal values of limit transient probabilities of the system operation process at the particular operation states that allows to find the best system safety function and other safety indicators, through applying the created system safety model and linear programming. Next, to find the system operation total costs in the safety state subsets, corresponding to this system best safety indicators, we replace the limit transient probabilities at the particular operation states, existing in the formula for the system operation total costs in the safety state subsets, by their optimal values existing in the formulae for the coordinates of the system safety function after maximization. On the other hand, to analyze jointly the system operation cost and its safety optimization, we propose the procedure of determining the optimal values of limit transient probabilities of the system operation process at the particular operation states that allows to find minimal system operation total cost in the safety state subset not worse than the critical safety state, using the created system operation cost model and linear programming. After that, to find the system conditional safety indicators, corresponding to this system minimal total operation cost in the safety state subset not worse than the critical safety state, we replace the limit transient probabilities at particular operation states, existing in the formula for the system safety function coordinates, and for remaining system conditional safety indicators by their optimal values existing in the formulae for the system minimal total cost in the safety state subset not worse than the critical safety state. The created models are applied separately and jointly to the port oil terminal. Moreover, to fulfil the obtained port oil terminal optimal safety and operation cost results the modifications of its operation process are proposed. The evaluation of results achieved is performed and the perspective for future research in the field of the complex systems, including port oil terminal, safety and their operation costs joint analysis and optimization is given.

The model of system safety impacted by operation process is introduced and the procedure of its safety maximization is proposed. The model of system operation total cost during the fixed operation time is introduced and the procedure of its minimization is presented. To analyse jointly the system safety and its operation cost optimization, we propose the procedure of determining the optimal values of limit transient probabilities of the system operation process at the particular operation states that allows to find maximal system safety indicators, through applying the created system safety model and linear programing. Next, to find the system conditional operation total cost during the fixed operation time, corresponding to this system maximal safety indicators, we replace the limit transient probabilities at the particular operation states, existing in the formula for the system operation total cost during the fixed operation time, by their optimal values existing in the formulae for the coordinates of the system safety function after maximization. The created models are applied to the port oil terminal critical infrastructure to maximize its safety indicators and to minimize its operation total cost during the fixed time separately. After that the port oil terminal critical infrastructure operation total cost during the fixed operation time corresponding to its maximal safety indicators is found. The evaluation of results achieved is performed and the perspective for future research in the field of the complex systems including critical infrastructures safety and their operation costs joint analysis and optimization is given.

The model of system operation total cost during the fixed operation time is introduced and the procedure of its minimization is presented. The model of system safety impacted by operation process is introduced and the procedure of its safety maximization is proposed. To analyse jointly the system operation cost and safety optimization, we propose the procedure of determining the optimal values of limit transient probabilities of the system operation process at the particular operation states that allows to find the minimal operation total cost during the fixed operation time, through applying the created system general operation cost model in the fixed operation time and linear programming. Next, to find the system conditional safety indicators, corresponding to this system minimal total operation cost during the fixed operation time, we replace the limit transient probabilities in particular operation states, existing in the formula for the system safety function coordinates, by their optimal values existing in the formula for the system minimal total cost during the fixed operation time. Further, applying this formula for the system conditional safety function coordinates, related to the system minimal operation total cost during the fixed operation time, we find the remaining system conditional safety indicators. The created models are applied to the maritime ferry technical system to minimize the mean value of the system operation total cost during the fixed operation time of one month and to maximize its safety indicators. After that, the ferry technical system safety indicators corresponding to its minimal mean value of operation total cost are found. The evaluation of results achieved is performed and the perspective for future research in the field of the complex systems including critical infrastructures operation costs and safety joint analysis and optimization is given.

W artykule przedstawiono wybrane aspekty dotyczące kosztów realizacji przewozu towarów transportem kolejowym. Koszty te zależne są przede wszystkim od systemu przemieszczania ładunków. Wagony z towarem mogą być przemieszczane w systemie zwartym lub rozproszonym. Cechą systemu zwartego przewozów jest fakt, że cały przejazd dokonywany jest jednym pociągiem, zasadniczo przy użyciu jednego środka transportu, bez konieczności wykonywania kosztownej pracy manewrowej na stacjach pośrednich. Wielkość jednocześnie nadanych towarów wywiera zasadniczy wpływ na koszt przewozu. W systemie rozproszonym, gdy wielkość nadanych towarów nie umożliwia uruchomienia ze względu na koszty pociągu bezpośredniego, przewozy są znacznie droższe. Wymagają dużej ilości pracy manewrowej i ekspedycyjnej. W konsekwencji generują znacznie większy koszt i dłuższy czas przemieszczania wagonów w tym systemie.

EN

The paper presents selected aspects regarding the costs of transporting goods by rail. These costs depend primarily on the selected freight system. Carriages loaded with goods can be moved in either a compact or a distributed system. A compact system can be described as such, in which the entire journey is made by one train, without having to perform expensive maneuvering work at intermediate stations. The volume of goods being dispatched at a given time has a significant impact on the cost of transport. In a distributed system, when the volume of goods is not sufficient to run a direct train, the transportation costs become higher. The shipment requires a lot of maneuvering and dispatching work. As a consequence, the cost of using this system is higher and it results in longer wagon relocation times.

W artykule przedstawiono analizę wpływu systemu ogrzewania na zużycie energii i koszty eksploatacyjne 3-kondygnacyjnego budynku zamieszkania zbiorowego (dom studencki) o powierzchni 2117,16 m2. Budynek miał niskie zapotrzebowanie na ciepło użytkowe do ogrzewania i wentylacji na poziomie 36,85 kWh/(m2rok). Uwzględniono 5 wariantów technologicznych systemu centralnego ogrzewania (CO) i przygotowania ciepłej wody użytkowej (CWU). Wyniki wykazały, że ogrzewanie budynku pompą ciepła może 2-6 razy zmniejszyć zapotrzebowanie budynku na energię końcową. Po uwzględnieniu cen nośników energii i kosztów amortyzacji urządzeń grzewczych rozwiązaniem najbardziej optymalnym z ekonomicznego punktu widzenia jest kocioł węglowy. Rozwiązaniem o najmniejszym zapotrzebowaniu na energię pierwotną jest kocioł na pellety drewniane.

The article presents the analysis of the impact of the heating system on energy consumption and exploitation-related expenses for a 3-storey mass accommodation building (student dormitory), with an area of 2117.16 sq. m. The building had low heat requirements, shaped at the level of 36,85 kWh/sq. m/year. 5 technological variants of the central heating and water heating systems have been considered. The results have shown that heating the building with a heat pump may lead to reduction of the amount of the final energy that would be required to maintain the temperatures in the building. After the prices of energy carriers, along with the depreciation costs of the heating devices have been taken into account, it turned out that a coal powered boiler is the best solution, at least economically. The solution, in case of which the primary power requirements are the smallest is a boiler heated with the use of wooden pellets.

Analiza użytkowania środków mechanizacji w 28 modelach gospodarstw rodzinnych wskazuje na wysoki poziom wykorzystania maszyn i ciągników, czemu sprzyja znaczny obszar przyjętych do badań gospodarstw (średnio 54,8 ha UR). Zróżnicowanie wykorzystania analizowanych zestawów maszyn w niewielkim stopniu oddziałuje na zmienność łącznych kosztów prac maszynowych. Koszty te są głównie pochodną poziomu wyposażenia gospodarstw w środki mechanizacji. Przyjęte do badań wskaźniki i zastosowana w pracy metoda unożliwiają ocenę wpływu intensywności użytkowania zestawów maszyn na zmienność kosztów ich eksploatacji.

These costs are mainly derivative from level of farm equipment with mechanization means. Assumed in the study indicators and applied research method enabled to evaluate the effect of using intensity of the machine sets on variability in their operation costs.
