The application of methods using graphs to model a variety of engineering issues has been known for several decades, but the application of graph algorithms to model the urban water management issues is a completely new approach. The article reviews the scientific literature on integrated urban water management systems in terms of the use of graph theory algorithms in this topic. Such a review has not been done before and constitutes a completely novel study. Some of the algorithms presented are directly derived from graph theory, while others were developed from other sciences, including environmental engineering or genetics, to solve specific engineering problems. The paper presents a general scheme and a brief description of the most important components of an integrated urban water management system. The necessary concepts of graphs were defined, the origin and the principle of graph algorithms used in modeling water management issues (Loop-By-Loop Cutting Algorithm, Hanging Gardens Algorithm, Tree Growth Algorithm, Dijkstra’s Algorithm, Genetic Algorithm, and Bayesian Networks Algorithm) were described. Their use in modeling the issues in stormwater, sanitary sewage and water distribution system was described. A complete list of scientific literature in this field was provided.

Innovations become the basis for the competitiveness of enterprises, lead to greater efficiency, better quality of products and services. The process of innovative activity requires enterprises to develop and implement a mechanism for managing innovation activities which is adequate to the requirements of a market economy. Moreover, for the process of implementation of innovative technologies in the enterprise, it is necessary to have a clearly formulated strategy for the development of innovation activity at the level of a country, region, industry and enterprise. Taking into account all the above, it can be noted that a competent policy in the field of innovation is not only a problem of a country, but also a problem of every enterprise, the basis of competitive advantages of which should be the implementation of innovative technologies and application of the results of scientific and technological progress. Scientific and technological progress also means the development of information and communication technologies in the economic sectors. The aim of this study is to consider innovation management systems, analyze and describe the types of innovations and creating recommendations for improving the competitiveness of enterprises in tough innovative competition.

Innowacje stają się podstawą konkurencyjności przedsiębiorstw, prowadzą do większej wydajności, lepszej jakości produktów i usług. Proces działalności innowacyjnej wymaga od przedsiębiorstw opracowania i wdrożenia mechanizmu zarządzania działaniami innowacyjnymi, który byłby adekwatny do wymagań gospodarki rynkowej. Ponadto w procesie wdrażania innowacyjnych technologii w przedsiębiorstwie konieczna jest jasno sformułowana strategia rozwoju działalności innowacyjnej na poziomie kraju, regionu, przemysłu i przedsiębiorstwa. Biorąc pod uwagę wszystkie powyższe, można zauważyć, że kompetentna polityka w dziedzinie innowacji to nie tylko problem kraju, ale także problem każdego przedsiębiorstwa, którego podstawą przewagi konkurencyjnej powinno być wdrożenie innowacji technologie i zastosowanie wyników postępu naukowego i technologicznego. Postęp naukowy i technologiczny oznacza także rozwój technologii informacyjnych i komunikacyjnych w sektorach gospodarki. Celem tego badania jest rozważenie systemów zarządzania innowacjami, analiza i opisanie rodzajów innowacji oraz opracowanie zaleceń dotyczących poprawy konkurencyjności przedsiębiorstw w trudnej konkurencji innowacyjnej.

Satellite gravimetry is a powerful and reliable tool for regional tectono-geodynamic zonation. The studied region contains intricate geodynamical features (high seismological indicators, active rift systems and collision processes), richest structural arrangement (existence of mosaic blocks of oceanic and continental Earth’s crust of various age), and a number of high-amplitude gravity anomalies and complex magnetic pattern. The most hydrocarbon reserves of the world and other important economic deposits occur in this region. Comprehensive analysis of satellite gravity data with application of different approaches was used to develop a sequence of maps specifying crucial properties of the region deep structure. Careful examination of numerous geological sources and their combined examination with satellite gravity (main), magnetic, GPS, seismic, seismological and some other geophysical data enabled to develop a new tectonic map of the Arabian–African region. Integrated analysis of series of gravity map transformations and certain geological indicators allowed to reveal significant geodynamic features of the region.
