Opis:
Fiber To The Home (FTTH) is the most ambitious among optical technologies applied in the access segment of telecommunications networks. The main issues of deploying FTTH are the device price and the installation cost. Whilst the costs of optical devices are gradually decreasing, the cost of optical cable installation remains challenging. In this paper, the problem of optimization that has practical application for FTTH networks is presented. Because the problem is Non-deterministic polynomial-time hard (NP-hard), an approximation algorithm to solve it is proposed. The author has developed the algorithm in a C# program in order to analyze its performance. The analysis confirms that the algorithm gains near-optimal results with acceptable time consumption. Therefore, the algorithm to be applied in a network design tool for FTTH network planning is proposed.

Opis:
For more than ten years a dynamic and intensive development has been observed in spatial information technology combining elements of geoinformatics with data from various sources in order to create elaborate, often interdisciplinary and multifunctional compilations. The progressing implementation of IT solutions with reference to resources and related trends to make public information that is useful to a wide group of recipients are reflected in multimedia information materials of many public institutions and private businesses. An example of using electronic technologies in the presentation of spatial data of national parks is widely available geoportals, interactive maps and other cartographic or paracartographic visualizations offering various tools allowing the utilisation of spatial information resources. This publication aims at a multi-level analysis of the availability of network services, as defined in Directive 2007/2/EC of the European Parliament and of the Council of 14 March 2007 establishing an Infrastructure for Spatial Information in the European Community, to all the existing geoportals of Polish national parks and a review of additional functions offered by the map services of all 23 Polish national parks that may be useful to users. As a result of research, tables and descriptions comparing the functions of the analysed geoportals were compiled and additional practical tools observed in other services were described. In addition, based on the comparisons, a concept of geoportal optimization was developed taking into account all categories of spatial information services and optional functions.

Opis:
Fiber To The Home (FTTH) to najbardziej nowoczesna technologia wśród światłowodowych sieci dostępowych. Podstawowymi wyzwaniami w procesie budowy sieci FTTH są wysoka cena urządzeń i koszt instalacji kabli. Cena urządzeń optycznych wprawdzie stale się obniża, jednak położenie kabla optycznego nadal generuje bardzo duże koszty. W niniejszym artykule przedstawiono problem optymalizacji kosztów instalacji kabla optycznego. Jego rozwiązanie będzie miało praktyczne zastosowanie w projektowaniu sieci FTTH. Ponieważ prezentowany problem jest NP-trudny (Non-deterministic Polynomial-time hard), w celu jego rozwiązania posłużono się algorytmem aproksymacyjnym. Algorytm został zaimplementowany w celu analizy wydajności, która wykazała zadowalającą jakość wyników działania algorytmu z dopuszczalną czasochłonnością. W związku z tym autor proponuje zastosowanie algorytmu w narzędziach do projektowania sieci FTTH.

Opis:
Sustainable development is an very important idea nowadays and it influences on many factors. It is very important to focus on the goals of sustainable development and implement them both in industry and in everyday life. The aim of the article is to analyse the impact of implementing an automatic conveyor belt transport system between the stands of an exemplary assembly line on sustainable development in economic and environmental terms. The analyzed production process consists of one production line with six assembly stations. The efficiency of individual design solutions and electricity consumption were adopted as the evaluation criteria. To compare the two processes, a simulation analysis was performed in the Plant Simulation program. First chapter is the introduction to the article. The second chapter describes the current applications of simulation tests. The third chapter describes the production system that is improved by adding conveyors. The next chapter compares the processes with and without the use of conveyors and presents how much energy must be used additionally by imple-menting conveyor belts, but also what energy savings can be obtained by installing additional stop sensors. The fifth chapter presents the conclusions: the conducted research allowed concluding that the implementation of conveyor belts affects a higher number of finished products at the same time as the transport of components is manual. However, the best solution is to use conveyors with stop sensors, and the power consumption is then low and more profitable for the enterprise.

Opis:
Contemporary rural landscapes in Poland are being changed intensively and adversely. These changes lead to landscape disharmony, spatial disorder, the blurring of individual and specific features and disruption to the ecological equilibrium. This article aims to present general rules for the optimization of rural landscapes. It discusses the causes and consequences of unfavourable changes within Poland’s rural landscapes which constitute a threat to their sustainable development. The authors attempt to identify the major factors to be considered in taking steps aimed at landscape optimization. Landscape equilibrium may be assessed through the sustainable development dimensions: ethical, ecological, social, economic, technical, political and legal. Landscape optimization consists in maintaining the balance within these dimensions.

Opis:
Model calculations were conducted to optimize and compare alternative schemes of CMS-line development in hybrid rye breeding on the basis of their expected selection gain per year assuming a fixed annual budget. Selection gains are predicted using current estimates of the relevant quantitative-genetic and economic parameters. Two alternative schemes are dealt with here. The first scheme (STD) represents a standard procedure in present-day second-cycle breeding. The second scheme (POP) is especially suited for population material that has not undergone intense inbreeding and selection yet. We:(i) give the optimum dimensioning of the schemes and their relative efficiency, (ii) study the effect of alterations in the dominance variance, the genotype × environment-interaction variance, and the budget, and (iii) assess how deviations from the optimum dimensioning affect the selection gain.Assuming identical genotypic variances, scheme STD is clearly superior to POP. It should thus always be used for second-cycle material. If, however, the population material used with scheme POP offers larger genotypic variances than the second-cycle material, POP becomes competitive. Changes in genetic and economic parameters affect the dimensioning but not the ranking of the schemes. Deviations from the optimum dimensioning only slightly reduce the selection gain as long as they are not too severe. This is shown for suboptimum numbers of testers and locations. All in all, the results demonstrate the importance of optimizing breeding schemes with respect to genetic, technical, and economic aspects.

Opis:
The specificity of tool provisioning is conditioned using tooling, the quantity of which exceeds the nomenclature of the manufactured goods considerably. Therefore, for modern enterprises, first-priority issues are harmonizing the processes of tool provisioning systems, increasing the level of the reaction of this system to changes, obtaining operational control over the production system, and, thus, improving the efficiency of the production process. In this paper, a mathematical model of decision-making based on determining the optimal strategy for the process flow was proposed to improve the efficiency of the information system for quality management of tool provisioning. It is suggested to use the sustainable development factor of information system for quality management of tool provisioning to make decisions about the path of the tooling process, which considers the requirements of international standards for management systems (ISO 9001, ISO 45001, etc.). This model is based on the application of graph optimization theory, fuzzy logic, and Markov chains. The use of this model is universal and will increase the validity of operational management decisions, increase productivity, reduce resource dependency, and, therefore, reduce the costs of tool provisioning, which directly affects the cost of production and competitiveness of the enterprise as a whole.

Opis:
In the field of computer game development, there are numerous optimization methods that help to significantly reduce the number of calculations that the game system performs while playing the game. In its turn, this allows to display increasingly realistic graphics. The paper presents the performed analysis of general optimization methods used in the game engine Unreal Engine, such as Distance Culling, Occlusion Culling, Frustum Culling, LODs, Level Streaming,and the Nanite System. The main factors such as resource intensity, visual quality, number of objects, and scale have been determined.The research results demonstrate that properly applied optimization methods can improve game performance and reduce the computational loadon the system, which is crucial both functionally and aesthetically.
W dziedzinie tworzenia gier komputerowych istnieje wiele metod optymalizacyjnych, które pozwalają znacznie zredukować liczbę obliczeń, jakie wykonuje system gry podczas renderowania, co z kolei pozwala na wyświetlanie coraz bardziej realistycznej grafiki. W pracy przeprowadzono analizę ogólnych metod optymalizacji stosowanych w silniku gier Unreal Engine, takich jak Distance Culling, Occlusion Culling, Frustum Culling, LODs, Level Streaming oraz Nanite System. Zidentyfikowano główne czynniki, które mają znaczenie: zużycie zasobów, jakość wizualna, liczba obiektówi skalowalność.Wyniki badań pokazują, że prawidłowo zastosowane metody optymalizacji mogą poprawić wydajność gry i zmniejszyć obciążenie systemu obliczeniowego, co jest istotne zarówno pod względem funkcjonalnym, jak i estetycznym.

Opis:
Today, almost 80% of cargo is transported by sea. Most of the global maritime shipping operations are performed in the direction East – West, through the southern routes, e.g. Singapore – Suez Canal – Gibraltar – Europe. The total fuel cost is the major concern and the main drawback of these routes. According to the latest statistics and analyses, the price of fuel is growing and such a trend will cause a great impact on the economies of developing countries. For these reasons, new alternative maritime routes, in which the optimisation of transportation in the maritime transport network can be achieved, are to be found. There is a possibility of establishing such routes in the areas of high latitudes where climatological changes and diminishing ice open up entirely new possibilities for shipping and present completely new challenges in the global shipping industry. Through the comparative analysis of the main routes and the SWOT (Strengths, Weaknesses, Opportunities and Threats) method, this paper discusses the advantages, potential and importance, as well as the level of reliability, threats and disadvantages of using the areas of high latitude in maritime transport.

Minimum Production Time model of the machining process optimization problem comprising seven lathe machining operations were developed using Genetic Algorithms solution method. The various cost and time components involved in the minimum production cost and minimum production time criteria respectively, as well as all relevant technological/practical constraints were determined. An interactive, user-friendly computer package was then developed in Microsoft Visual Basic.Net environment to implement the developed models. The package was used to determine optimal machining parameters of cutting speed, feed rate and depth of cut for the seven machining operations with twenty-three technological constraints in the conversion of a cylindrical metal bar stock into a finished machined profile. The result of the single-objective machining process optimization models shows that the minimum production time is 21.84 min.
