Zagadnienie zarządzania statkami (ang. ship management) jest rzadko poruszane w polskiej doktrynie. Istnieją różne przyczyny takiego stanu rzeczy, aczkolwiek niewątpliwie znaczący jest priorytet nadany w politycznym, prawnym jak i ekonomicznym dyskursie zagadnieniom prawnym poświęconym właścicielom statków. Obecny trend utrzymuje się pomimo faktu, iż ponad 73% światowego tonażu jest zarządzane przez specjalistyczne podmioty „ship managerskie”. Analiza ekonomiczna rok po roku dostarczała dowodów, że Polska przestała być krajem liczącym się pod względem ilości posiadanych przez nią statków i ten trend nie ulegnie odwróceniu w perspektywie krótko i średnioterminowej. Polska może jednak odegrać kluczową rolę w świecie żeglugi poprzez przekształcenie się w centrum zarządzania statkami. Niniejszy artykuł ma na celu przedstawienie wybranych aspektów zarządzania statkami morskimi.
The purpose of the author was to indicate the deficiency of development management instruments currently used to the territorialization of policies in stimulating intra- and intersectoral partnership cooperation. Her reflections were based on the results of research commissioned by the Polish Ministry of Development and Investment by a team in which the author participated. These studies have revealed that the weakest impacts of the so-called territorial instruments include the ability to mobilize various stakeholder groups to take action and to create partnership cooperation. Against this background, the author has undertaken the analysis of the potential impact of territorial tools on the partnerships development and has attempted to present recommendations for practice and further research in this area.
The basis for a mineral deposit delimitation is a qualitative and quantitative assessment of deposit parameters, qualifying a deposit as an economically valuable object. A conventional approach to the mineral deposit recognition and a deposit detailed parameters qualification in the initial stages of development work in the KGHM were presented in the paper. The goals of such recognition were defined, which through a gradual detailed expansion, resulting from the information inflow, allows for the construction of a more complete decision-making model. The description of the deposit parameters proposed in the article in the context of fuzzy logic, enables a presentation of imprecise statements and data, which may be a complement to a traditional description. Selected non-adjustable and adjustable s-norm and t-norm operators were demonstrated. Operators effects were tested for selected ore quality parameters (copper content and deposit thickness) by constructing adequate membership functions. In a practical application, the use of chosen fuzzy logic operators is proposed for the assessment of the qualitative parameters of copper-silver ore in the exploitation blocks for one of the mines belonging to KGHM Polish Copper S.A. The considerations have been extended by including the possibility of using compensation operators.
The size and complexity of decision problems in production systems and their impact on the economic results of companies make it necessary to develop new methods of solving these problems. One of the latest methods of decision support is business rules management. This approach can be used for the quantitative and qualitative decision, among them to production management. Our study has shown that the concept of business rules BR can play at most a supporting role in manufacturing management, but alone cannot form a complete solution for production management in foundries.
Current power grid and market development, characterized by large growth of distributed energy sources in recent years, especially in Europa, are according energy storage systems an increasingly larger field of implementation. Existing storage technologies, e.g. pumped-storage power plants, have to be upgraded and extended by new but not yet commercially viable technologies (e.g. batteries or adiabatic compressed air energy storage) that meet expected demands. Optimal sizing of storage systems and technically and economically optimal operating strategies are the major challenges to the integration of such systems in the future smart grid. This paper surveys firstly the literature on the latest niche applications. Then, potential new use case and operating scenarios for energy storage systems in smart grids, which have been field tested, are presented and discussed and subsequently assessed technically and economically.
