Purpose Over the past two decades, in developed countries a trend towards the liberalization and restructuring of the gas market has been observed. Today, restructuring is an ongoing process. In this study, a restructured natural gas market has been considered in which several regional distribution companies have ownership of the network and are competing against each other to gain more benefits. The main purpose of this study is to achieve efficiency and economic rationality in such a market through horizontal cooperation. Design/methodology/approach A restructured natural gas distribution network is modeled as a cooperative game to estimate the potential cost savings for various collaboration scenarios. In addition, the cost savings’ allocation among collaborating companies is evaluated using the cooperative game theory. Findings The results reveal validity and efficiency of the solution of the proposed model and capabilities of the cooperative game theory for reduction in gas distribution costs and improvement in the service level. Research limitations/implications This study is limited to natural gas in one region of Yazd City in Iran. Moreover, one segment of the natural gas network (i.e. distribution network) is modeled. Moreover, long-term cooperation between companies relies on fair distribution of cooperation benefits to the participants. Practical implications For the purpose of comparison and to get an insight into properties of the cost savings game, the real case study of one region of Yazd city in Iran is implemented. Originality/value This study contributes to the competitive models in the restructured gas market, particularly, in gas distribution network. The main contribution is to provide potential benefits for the participants via the horizontal cooperation.

The formation of the modern Ukrainian natural gas market is accompanied by profound transformations of the national gas infrastructure: the creation and operation of new market operators, the redistribution of infrastructure facilities, the development and implementation of new requirements for the effective functioning of the entire system. At the same time, this requires from all parties a verified and balances strategy for the optimal implementation of all the obligations that Ukraine has undertaken to fully implement the requirements of the EU Third Energy Package, which aims to create an effective natural gas market based on the principles of free competition, proper consumer protection and security of supply. Despite the fact that the capacity of the Ukrainian gas transmission system and gas storages is one of the largest in Europe, the unbanding process has caused a number of threats in the area of regulatory support for production activities, requiring the consolidation of specialists' efforts to form optimal solutions to the problems that have arisen. In addition, the lengthy process of reforming and reorganizing the Ukrainian gas distribution system has led to a situation where the work of a natural gas distribution operator is facing a risk of imbalance in terms of inefficient standardization of the main areas of operation to meet the EU legislation requirements implemented in Ukraine. Therefore, to develop basic directions for the future work of gas infrastructure operators, it is necessary to take into account the acting capabilities of existing system for transportation, underground storage and gas distribution (taking into account the significant number of standardized indicators defined by the existing normative documents of the former USSR) and in accordance with the trends in the development of the European gas infrastructure introduce economically and technically feasible measures to standardize performance activities. Such works have to be incorporated into integrated research programs, during which regional and international trends are to be taken into account and adapted, the results of which will be the basis for future roadmaps and programs for the development of natural gas supply and distribution systems.

The method presented in this chapter computes an estimate of the location of a single gas source from a set of localized gas sensor measurements. The estimation process consists of three steps. First, a statistical model of the time-averaged gas distribution is estimated in the form of a two-dimensional grid map. In order to compute the gas distribution grid map the Kernel DM algorithm is applied, which carries out spatial integration by convolving localized sensor readings and modeling the information content of the point measurements with a Gaussian kernel. The statistical gas distribution grid map averages out the transitory effects of turbulence and converges to a representation of the time-averaged spatial distribution of a target gas. The second step is to learn the parameters of an analytical model of average gas distribution. Learning is achieved by nonlinear least squares fitting of the analytical model to the statistical gas distribution map using Evolution Strategies (ES), which are a special type of Evolutionary Algorithm (EA). This step provides an analysis of the statistical gas distribution map regarding the airflow conditions and an alternative estimate of the gas source location, i.e. the location predicted by the analytical model in addition to the location of the maximum in the statistical gas distribution map. In the third step, an improved estimate of the gas source position can then be derived by considering the maximum in the statistical gas distribution map, the best fit, as well as the corresponding fitness value. Different methods to select the most truthful estimate are introduced, and a comparison regarding their accuracy is presented, based on a total of 34 hours of gas distribution mapping experiments with a mobile robot. This chapter is an extended version of the conference paper (Lilienthal et al., 2005).

The analysis of the influence of the main factors on the kinetics of the drying process of fermented wheat raw materials in a vibro-boiling layer is presented. The purpose of the study is to study the influence of the main technological parameters on the kinetics of the drying process of fermented wheat raw materials in a vibrating boiling overflowing layer at atmospheric pressure. The main factors affecting the drying process were selected: the temperature of the drying agent supplied to the dryer, the speed of the drying agent, the vibration amplitude of the gas distribution shelves, the vibration frequency of the gas distribution shelves. The influence of temperature and air velocity on the drying process of raw materials, the influence of the amplitude and frequency of oscillations of the gas distribution grid on the kinetics of the drying process of the fermented product, as well as the influence of the specific load of the product on the process of moisture removal are shown An analysis of the curves shows that with an increase in the amplitude of the oscillation, it reduces the drying time, and an increase in the frequency of oscillation of the shelves contributes to a decrease in the drying time. In this case, a uniform increase in the drying intensity is observed over the entire range of the amplitudes considered. An increase in the oscillation frequency of the gas distribution grid also helps to reduce the duration of the drying process of fermented wheat raw materials. It should be noted that the amplitude of the oscillations more strongly affects the decrease in the drying time of the raw material than the frequency Thus, we concluded that in the intervals under study the changes in the amplitude and frequency of vibrations of perforated shelves on the drying process of fermented wheat raw materials are more strongly affected by the amplitude of vibrations. In addition, when choosing vibration parameters, the specific load of the material on the grate and its initial humidity should be taken into account..

Introduction. The gas distribution system in the regions of the state is significantly influenced by both external and internal factors, and like any economic structure in a competitive environment must strive for effective economic development. The quality of such development depends to a large extent on the state’s ability to ensure the formation of an appropriate regulatory environment, both at national and regional taxonomic levels. Gas markets in the regions of Ukraine face a number of development problems caused by the lack of proper competitiveness conditions, the need to improve technical and technological support of capital assets, the formation of a balanced tariff system that would allow to reconcile the interests of both gas suppliers and consumers. This will contribute to the formation of liberalized gas markets in the regions of the country and at the national level. The purpose. The purpose of the research is to identify regional features and problems of organizational and economic regulation of the functioning of gas distribution companies in Ukraine and recommendations substantiate for improving the efficiency of regulatory processes. Results. In the article the development peculiarities of regulation processes of gas distribution companies in the regions of Ukraine are analyzed. The problems of forming the organizational and economic support of the functioning of the state gas market are outlined. Recommendations for improving the efficiency of the gas distribution system in the regions of the state are justified and the prospects for its development have been determined. Conclusion. It is noted that the efficiency and reliability of the gas transportation system depends on the effectiveness of organizational and economic support – the activities of economic entities that influence the development of gas distribution companies through the interaction between individual participants in the gas market and market infrastructure. Keywords: gas transportation system, gas transportation company, gas distribution companies, tariff, pricing, energy security, gas security, institualization, organizational and economic mechanism, Ukraine.
