This paper presents general patterns in airline pricing behaviour and a methodology for analysing different routes and/or carriers. The purpose is to provide customers with the relevant information they need to decide the best time to purchase a ticket, striking a balance between the desire to...

The timing of variables for stream flow prediction models remains a common problem, particularly with regards to stream flow data-driven based models. Accurate estimation of lag time (Lt), which is representative of time interval, is a potential solution to this problem. The main objective of...

The paper deals with the actual problem of the functioning and development of district heating systems in the framework of the transition to intelligent energy, in which the active consumers (prosumers) holds the key place. The paper proposes an optimization mathematical model for management the...

The paper deals with the problem of operating the reliability of prosumers as part of a district heating system, taking into account overload time redundancy that they possess. This time redundancy can be both passive, caused by heat accumulating effect and use of thermal energy storages, as...

The analysis and synthesis of reliability of energy systems, particularly district heating systems (DHS), is based on probabilistic modeling of different system states and events connecting these states (usually, these are failures and restoration of system components). The paper deals with the...

This study presents the exergoeconomic analysis and evaluation in order to provide cost based information and suggests possible locations/components in a GDHS (geothermal district heating system) for improving the cost effectiveness. The analysis is based on the SPECO (specific exergy costing)...

The delivery cost of forest biomass to energy plants is one of the determining factors in feasibility of using forest biomass for heat and power generation. The variability in available forest biomass during the year is another important factor that should be considered in feasibility studies...

A dominant share of Croatian cogeneration capacity and future cogeneration potential belongs to district heating systems currently operating in almost all bigger mainland and coastal towns. Since public cogeneration and public heating plants cover only 10% of heating requirements of households...
