Efficiency And Reliability

The current state of water supply in Ukraine was analyzed and the main problems that arise on the existing water supply systems, related to the lack of efficiency of both water treatment technologies and operation conditions of the water supply system structures, characterized by high energy consumption, excess pressure formation and accident rate increase were studied. It was specified that in agricultural water supply systems additional difficulties can arise due to significant fluctuations of water consumption during the day, therefore, there is a need for the study of the joint work of interacting structures, especially in the towerless schemes. It is shown that to solve the problems of reliable provision of consumers with the required water amounts, water pressures and water quality, is possible taking into account the requirements of economy, reliability and environmental safety, and to identify weaknesses and develop recommendations for ensuring the efficient operation of structures can be fulfilled by mathematical modeling and analysis of various possible variants of system operation. The issue of increasing the efficiency and reliability of agricultural supply systems was considered using the example of the water supply system in Tarasivka village of Kyiv region. The article deals with increasing the efficiency and reliability of agricultural water supply systems. The results of the study of water supply systems operation, based on the utilization of ground water in the village of Tarasivka, Kyiv region are given, which demonstrate that when pumping water from the well directly into the water supply network, excess damage energy for water lift occurs. The reliability of the water supply system, when pumping water from the well, was analyzed and the measures to ensure cost-effective and reliable operation of water supply structures while reducing the specific costs of electricity for supplying water to consumers and improving its quality were proposed.

Recent surveys on the B2B market in the Czech Republic show clearly that most of the addressed managers consider reputation as the most important factor of the competitiveness of their companies. Therefore, it is possible to regard mastered reputation management as the basis for creation of a unique competitive advantage, which finally results in deepening of the positive relationships with all the stakeholders. The paper presents the outcomes of primary quantitative surveys conducted within chemical product supply chains on the B2B market in the Czech Republic. The surveys aimed to identify factors that are crucial for building positive reputation of companies within supply chains and, at the same time, to assess and compare their importance as perceived by chemical product suppliers and their customers.

Policies to reduce carbon emissions are leading to substantial changes in the demand for electricity and to the structure of electricity supply systems, which will alter the cost structure of electricity supply. This can be expected to result in corresponding changes to the price structure faced by customers. This note is an initial exploration of how possible new price structures may impact on HVAC system and building design and use. Changes in the price structure of electricity supply (separately from changes in price levels) can significantly affect the cost-effective design and operation of building services systems; especially of heating and cooling systems. The nature and implications of these changes can have important implications for future system design and operation.

Engineering feedstock supply systems that deliver affordable, high-quality biomass remains a challenge for the emerging bioenergy industry. Cellulosic biomass is geographically distributed and has diverse physical and chemical properties. Because of this feedstock supply systems that deliver cellulosic biomass resources to biorefineries require integration of a broad set of engineered unit operations. These unit operations include harvest and collection, storage, preprocessing, and transportation processes. Design decisions for each feedstock supply system unit operation impact the engineering design and performance of the other system elements. These interdependencies are further complicated by spatial and temporal variances such as climate conditions and biomass characteristics. This paper develops an integrated model that couples a SQL-based data management engine and systems dynamics models to design and evaluate biomass feedstock supply systems. The integrated model, called the Biomass Logistics Model (BLM), includes a suite of databases that provide 1) engineering performance data for hundreds of equipment systems, 2) spatially explicit labor cost datasets, and 3) local tax and regulation data. The BLM analytic engine is built in the systems dynamics software package Powersim™. The BLM is designed to work with thermochemical and biochemical based biofuel conversion platforms and accommodates a range of cellulosic biomass types (i.e., herbaceous residues, short-rotation woody and herbaceous energy crops, woody residues, algae, etc.). The BLM simulates the flow of biomass through the entire supply chain, tracking changes in feedstock characteristics (i.e., moisture content, dry matter, ash content, and dry bulk density) as influenced by the various operations in the supply chain. By accounting for all of the equipment that comes into contact with biomass from the point of harvest to the throat of the conversion facility and the change in characteristics, the BLM evaluates economic performance of the engineered system, as well as determining energy consumption and green house gas performance of the design. This paper presents a BLM case study delivering corn stover to produce cellulosic ethanol. The case study utilizes the BLM to model the performance of several feedstock supply system designs. The case study also explores the impact of temporal variations in climate conditions to test the sensitivity of the engineering designs. Results from the case study show that under certain conditions corn stover can be delivered to the cellulosic ethanol biorefinery for $35/dry ton.

Purpose – Best-value supply chains characterized by agility, adaptability, and alignment, have become a crucial strategic means for firms to create and sustain competitive advantage in today’s turbulent environment. The purpose of this paper is to investigate linkage between best-value supply chains and firms’ competitive performance. Design/methodology/approach – In Study 1, survey data from 76 firms is used to test the impact of the three qualities of best-value supply chains on firms’ competitive performance. In Study 2, to test if a firm’s competitive advantage can be sustained through building best-value supply chains, a long-run performance analysis is conducted, which is based on a stock portfolio of firms identified from the American Marketing Association’s annual list of “Supply Chain Top 25.” Findings – The results of Study 1 indicate that the three qualities of best-value supply chains are positively related to firms’ competitive performance. The results of Study 2 show that firms having best-value supply chains generate significant and positive abnormal returns for shareholders over time. Originality/value – This is a multiple-method research, providing two-level empirical evidence to the investigation of theoretical linkage between best-value supply chains and firms’ competitive performance.

Gas Supply

This paper proposes taking into account new properties of gas supply systems in a mathematical model of flow distribution in comparison with the traditional formulation. The approach suggests introducing an arc coefficient, which allows for changes in the magnitude of gas flow passing along the arc, a vector of an increase in the arc throughput, and lower constraints on the gas flow along the arc. We also propose considering a new economic environment, namely, new criteria for optimizing the flow distribution and setting fictitious gas prices for consumers. These criteria enable us to take account of the priority gas supply to a definite group of consumers. As an example, the calculation of gas flows for the aggregated Unified Gas Supply System (UGSS) for 2030 is considered. This calculation takes into account the arc coefficients and the increase in the throughput of arcs.
