According to the research results the proposed economic-mathematical model can be used in the process of choosing an innovative strategy of the development of agro-industrial production, as well as to form targeted programs of innovative development and investment support of agro-industrial enterprises as a whole

Innowacyjne klastry światowych liderów handlu

The formation of a new global system and systemic global interdependence has generated new competitiveness factors for market participants, determining their appropriate strategic behavior to ensure a highly competitive position and leadership. Therefore, the purpose of the study is to identify the countries of intellectual leaders in the global market and the factors that influence the positions that countries achieve in terms of leadership. The following research methods were used: multifactor regression models, cluster analysis, and comparative analysis. Based on the authors’ methodology for assessing countries’ intellectual leadership, the clustering of countries in the global economy is determined. The evaluation algorithm was based on three levels: 1) resources, 2) the intermediate results of intellectual activity, and 3) the final results of overall progress.Using a multifactor regression model and cluster analysis, four clusters of countries were identified according to key indicators of intellectual leadership. For each cluster, the specialization of the two countries in terms of merchandise exports was analyzed: cluster 1 – the United States and Germany; cluster 2 – Israel and Italy; cluster 3 – Brazil and Ukraine; cluster 4 – China and South Korea. Each country is assigned an index of economic complexity, and the change in position of each country within a cluster over ten years is noted.An important goal is to understand the determinants of the leadership of countries in each geographic region.The analysis is based on the cluster analysis carried out in previous publications. The clustering of countries was carried out based on the dynamics of macroeconomic indicators over the past 15 years.Powstanie nowego systemu globalnego i systemowej współzależności globalnej wygenerowało nowe czynniki konkurencyjności dla uczestników rynku, określające ich strategiczne zachowania służące zapewnieniu wysoce konkurencyjnej i wiodącej pozycji. Dlatego celem badania była identyfikacja krajów będących intelektualnymi liderami na rynku globalnym oraz czynników wpływających na pozycję głównych krajów. Zastosowano następujące metody badawcze: modele regresji wieloczynnikowej, analizę skupień oraz analizę porównawczą. Na podstawie autorskiej metodologii oceny przywództwa intelektualnego krajów dokonano grupowania krajów w gospodarce światowej. Algorytm oceny opierał się na trzech poziomach: 1) zasobach, 2) pośrednich wynikach aktywności intelektualnej oraz 3) ostatecznych wynikach ogólnego postępu.Korzystając z modelu regresji wieloczynnikowej i analizy skupień, zidentyfikowano cztery klastry krajów wyodrębnione na podstawie kluczowych wskaźników przywództwa intelektualnego. Dla każdego klastra przeanalizowano specjalizację obu krajów w obszarze eksportu towarów: klaster 1 – Stany Zjednoczone i Niemcy; klaster 2 – Izrael i Włochy; klaster 3 – Brazylia i Ukraina; klaster 4 – Chiny i Korea Południowa. Każdemu krajowi przypisano wskaźnik złożoności gospodarczej i zarejestrowano zmianę pozycji każdego kraju w klastrze w ciągu dziesięciu lat.Ważnym celem jest zrozumienie uwarunkowań przywództwa krajów w każdym regionie geograficznym.Badania opierają się na analizie skupień przeprowadzonej we wcześniejszych publikacjach. Klasteryzacja krajów została przeprowadzona na podstawie dynamiki wskaźników makroekonomicznych w ciągu ostatnich 15 lat

Influence of agrometeorological component of the project environment on the duration of works in chemical protection projects of agricultural crops

The analysis of the state of science and practice of making managerial decisions in agricultural production projects is performed. The expediency of substantiation of the influence of the agrometeorological component of the project environment on the duration of works in the projects of chemical protection of agricultural crops is substantiated. The approach to the definition of fund of works time performance in projects of chemical protection of crops taking into account changing events of an agrometeorological component of the project environment is offered. It is based on the use of statistical data of agrometeorological stations in the regions where these projects are implemented. The peculiarity of this approach is that it provides for the formation of databases and knowledge for planning work in projects of chemical protection of agricultural crops based on the characteristics of a given project environment. To do this, computer simulation is used, which provides a systematic consideration of many variable agrometeorological components of the design environment and their impact on the limitation of the time allocated for work. This improves the quality of the database for forecasting the events of the components of the project environment, as well as gaining knowledge that underlies the acceleration of management decisions in projects of chemical protection of crops. It is established that the duration of agrometeorological determined daily fund of time for work in projects of chemical protection of agricultural crops is variable both during the life cycle of the project and in certain periods of its implementation, which is reflected by the relevant distribution laws. Further research on the planning of chemical protection projects for agricultural crops should be conducted to justify new methods and models of management decisions that will take into account the impact of changing events of the agrometeorological component of the project environment on the time and content of work in these projects

The Use of Hydrophytes for Additional Treatmnet of Municipal Sewage

At the current stage of discharge and treatment of municipal sewage and other types of wastewater in the territory of Ukraine, traditional technologies of biological treatment in aero-tanks by the process of aerobic oxidation involving active silt characterized by low efficiency are largely used. It was established that biological treatment and additional treatment of sewage involving hydrophytes are efficient. The research on wastewater quality and the efficiency of sewage treatment was conducted in three phases: Phase 1 – “the quality before treatment”, Phase 2 – “the quality after mechanical-biological treatment” at the existing municipal treatment plants, Phase 3 – “the quality after additional treatment by hydrophytes”. In order to determine the efficiency of using hydrophytes additional treatment, Eichhornia crassipes (water hyacinth) and the perennial aquatic plant Lemna minor were planted in one treatment pond. The results of the experiment made it possible to determine high efficiency of using hydrophytes for additional sewage treatment. In particular, the efficiency of additional treatment in the treatment ponds removing the residue of suspended pollutants for 40 days was 32%, toxic salts – 13.0–23.0%, oil products – 30.0%, biogenic substances – 68.5–83.3%. It caused a drop in the values of chemical and biological oxygen demand for 5 days by 89.6% and 61.2%, respectively. The efficiency of sewage treatment removing toxic salts and oil products reached 97.7%, whereas in the case of mineral and organic pollutants – up to 99%. That contributed to a considerable increase in the wastewater quality by the criteria for fisheries. In particular, high nutritional value of Eichhornia crassipes and Lemna minor allowed obtaining 12.5 tons of hydrophyte wet mass that can be used as green manure, feeds for farm animals, poultry and fish

Peculiarities of Implementation of Configuration Control Processes of Integrated and Innovative Projects of Logistics System Creation

The analysis of the current scientific and methodological principles of project management is performed. It is established that the existing models and methods cannot be used to control the configuration of integrated projects for the creation of logistics systems. The known toolkit provides general approaches to controlling the configuration of projects and does not take into account many factors of the design environment, which determine changes in the configuration of integrated projects for creating logistics systems. It has been substantiated that changes in the configuration of integrated projects for the creation of logistics systems are due to two groups of factors. They can be assessed by four criteria based on the determination of two generalized evaluative characteristics of the influence of the factors of the design environment on changes in the configuration objects of these projects. The scientific and methodological foundations of the configuration control of integrated projects for the creation of logistics systems are proposed, taking into account the changing components of their design environment. To control the configuration of integrated projects for the creation of logistics systems, the use of project management theory and system-factor principles is envisaged, which fully take into account the peculiarities of the implementation of these projects. Based on the proposed model, the impact of internal environment factors of integrated projects for the creation of logistics systems on changes in the configuration object No. 4.1 (a specialized tank truck for transporting perishable goods) was assessed. Significance coefficients are defined for each of the assigned codes (evaluation criteria and factors that determine the configuration changes) of the configuration objects of integrated projects for the creation of logistics systems. Their numerical value is in the range 0…1 and it characterizes the significance of each of the factors for a particular object of the configuration of integrated projects for the creation of logistics systems. Quantitative assessment of the impact of design environment factors on changes in the configuration of integrated projects for the creation of logistics systems is carried out on a 100-point scale
