Abstract

Ship management is a topic that has rarely been approached in the modern Polish maritime legal sciences. There are numerous reasons behind the present state of affairs but it seems that the foremost one is, that the focus in political, legal and economic discourse is still on the legal aspects of ship ownership. This trend continues despite the fact that today over 73% of world shipping tonnage is managed by the specialized ship management entities. An economic analysis has proven that year after year Poland was ceasing to be a large ship owning nation, it used to be, and that this trend is unlikely to be reversed in the short and mid-term perspective. Poland may, however, still continue to play a vital role in the world of shipping by becoming a ship management centre. This article aims to introduce the Readers to the selected aspects of ship management operations.

Abstract

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.

Abstract

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.

Abstract

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.
