Opis:
When conducting a dynamic simulation of a multibody mechanical system, the model definition may need to be altered during the simulation course due to, e.g., changes in the way the system interacts with external objects. In this paper, we propose a general procedure for modifying simulation models of articulated figures, particularly useful when dealing with systems in time-varying contact with the environment. The proposed algorithm adjusts model connectivity, geometry and current state, producing its equivalent ready to be used by the simulation procedure. Furthermore, we also provide a simple usage scenario-a passive planar biped walker.

Opis:
The article presents research verifying the transformation process of the retail structure in Wrocław. It is an interesting example of urban units which experienced the political and economic conditions of two different systems – socialist and capitalist, and also the period of changes in between. Following Palomäki and Zipser’s methodology, the analysis of retail hierarchy changes in Wrocław was carried for three time periods (1979, 1997, 2014). The hierarchy rate was based on 3-dimention data matrix: qualitative, quantitative and spatial. The important part of the research is the graphic visualisation of retail localisation changes. The methods used allow for determining the stable components of the retail system and tendencies of transformation. The results of the research point to important questions. First of all, the stable elements of the hierarchical retail system (stronger than political and economic changes) were observed in the town structure. The centre of  the town was recognised as a stable main point of the structure. Secondly, this high position of the centre  can be powered by big -box stores. Finally, the components of the system make it a multi -level one, with the number of levels in the hierarchy being changeable.
Przedstawione badania mają na celu weryfikację procesu transformacji struktury handlowej w jednym z polskich miast – Wrocławiu. Miasta polskie jako strefa przemian politycznych i społecznych transformacjiustrojowej stanowią tu szczególny walor porównawczy. Z wykorzystaniem metody M. Palomäkiego i W. Zipsera dokonano analizy zmian struktury hierarchii rejonów handlowych we Wrocławiu w trzech okresach badawczych (1979, 1997, 2014). Współczynnik hierarchii jest tu oparty na danych ilościowych i jakościowych oferty handlowej w rozmieszczeniu przestrzennym. Wyniki uzupełniają rozkłady przestrzenne sieci handlowej w mieście. Zastosowane metody pozwalają na wykrycie stabilnych elementów układu oraz uchwycenie kierunków przemian. Wnioski z badań wskazują na główne komponenty układu oraz tendencje przeobrażeń struktury handlowej Wrocławia. Po pierwsze, miasto ma stabilne elementy układu, w tym centrum, które w skali ogólnomiejskiej tworzy niepodważalnie najwyższą pozycję w hierarchii. Po drugie, nowoczesne formy handlu mogą stanowić element utrzymania lub wzrostu potencjału rejonów handlowych. Po trzecie, wszystkie elementy układu tworzą system o wielu poziomach hierarchii, których liczba stopni może być zmienna.

Opis:
Coastline is one type of valuable non-renewable resources. From the perspective of economic theory, it can gather population, promote traffic construction, and then improve the level of international trade. The research object of this paper is the coastline resource in Dafeng area. Firstly, we have a brief summary of the existing coastline evaluation literature, then introduce the location and natural attributes of the coastline resources in Dafeng. Following that, the Analytic Hierarchy Process (AHP) model is used to build the economic evaluation index system based on the characteristics of coastline in Dafeng. Specially, this index system consists of 6 factors, and a total of 41 detailed indicators were chosen including water depth, GDP, etc. On this basis, we use the assignment method to quantify the weight of each index, and calculate the comprehensive score of coastline resource by using the YAAHP software. The final conclusion is as follows: The total score of economic evaluation of coastline resource in Dafeng is 0.87. Therefore, the coastline resource in Dafeng will eventually be constructed a unique coastal economic zone, where the implemented port industrial projects will include shipbuilding, logistics, mechanical processing etc.

Opis:
Decomposition is the best method to analyze complicated systems. The whole system is divided into a set of smaller parts, i.e. subsystems. These items are connected to each other by input and output interfaces. Every subsystem could be analyzed using separate algorithms and procedures that are more suitable for solving the local task. In the article, a complicated electrical system is decomposed and the interaction decoupling mode is used to coordinate the local task solution. Each of the first–level subsystems, such as an optimization problem, is defined completely independently from the other problems. The subsystems are instructed to select the local input as well as the local interface output in an optimal fashion. The local task's solution depends not only on the internal subsystems’ parameters, but on the value of interfaces too. To achieve the global task solution, local tasks have to be coordinated using an appropriate coordination principle.

Opis:
At the moment the problem of dealing with external environment is an important issue of effective corporate strategic management in the enterprise. One of the factors of company interaction with external environment is company stakeholders. At the moment the theoretical basis of stakeholder analysis is researched insufficiently. The current research pursued the two goals: to show on which stage of strategic management process stakeholder analysis influences corporate activity and to provide effective theoretical and practical ground for the selection of stakeholders. In order to achieve the first goal the main aspects of stakeholder theory are reviewed in the paper. The place of stakeholder analysis in strategic management process is identified. It is argued that the interests of the most influential stakeholders should be considered in corporate goals, strategy and the strategic decision making process due to the “strategic necessity”. The latter means that consideration of the stakeholder influence leads to the increase of corporate performance effectiveness and fi nancial stability. The second objective is achieved through the review of possible techniques that could be used for stakeholder selection. The most appropriate for such purpose techniques are identifi ed by the analysis of their advantageous and disadvantageous. As the result of the review it is proposed to conduct the stakeholder selection basing on application of the Analytic Hierarchy Process (AHP). The example of application of such method for stakeholder selection is presented in the article.

Opis:
Municipal solid waste collection points (MSWCPs) are places where residents of municipalities can leave their waste free of charge. MSWCPs should operate in every municipality in Poland. The Geographic Information System (GIS) and analytical hierarchy process (AHP) were used in conjunction as tools to determine potential locations of MSWCPs. Due to possible social conflicts related to the location of MSWCPs, three variants of buffer zones for a residential area were adopted. As a result of the spatial analysis carried out using the GIS software, 247 potential locations were identified in variant no. 1 (which accounted for 7.1% of commune area), 167 for variant no. 2 (6.3% of commune area), and 88 for variant no. 3 (3.8% of commune area). The most favourable locations for MSWCPs were determined using the AHP method with additional criteria for which weights were calculated as follows: the area of a designated plot (0.045), actual designation of a plot in the local spatial development plan (0.397), distance from the centre of the village (0.096) and the commune (0.231), and population density of a village (0.231). The highest weights (over 50%) in the AHP analysis were obtained for 12 locations in variant no. 3, two of which had an area over 3 ha. The adopted methodology enabled to identify quasi-optimal solutions for MSWCP locations in the analysed rural commune. This research has the potential to influence future waste management policies by assisting stakeholders In the MSWCP location.

Opis:
Loss of the propulsion function by a ship is one of the most serious categories of hazardous events in sea transport. In specific external conditions it may lead to a loss of ship and environmental pollution. The consequences of propulsion loss by a ship are events classified by the International Maritime Organization as casualties or incidents. The probabilities of occurrence of the former events in a specific time unit constitute the propulsion risk of a ship. Determination of these probabilities is in practice confronted with difficulties connected with shortage of data. A method for estimating the risk caused by loss of a seagoing ship propulsion function is proposed. The estimation is fully based on the expert judgments. Expert is assumed to be well acquainted with the subject he is expected to formulate his judgment on. Expert should also be capable of formulating his judgment. This is connected with level of his education and the language used in the elicitation process, particularly as regards the parameters the expert is expected to estimate. This may be the language of numerical or linguistic values. Numerical values are better but are more difficult to articulate - also errors in judgments are more likely. To overcome this problem and to obtain a more accurate estimation, this study suggests using an analytic hierarchy process (AHP), which quantifies the subjective judgments and confirms the consistency of collected data. An example of the propulsion risk estimation of container carriers operating on the North Atlantic line allows to assess effectiveness of the method.

Land suitability assessment is an important stage in land use planning that guides the direction of optima land use. The objective of this study was to select a suitable location for settlements in earthquake-prone areas using the integration of the Analytical Hierarchy Process (AHP) and Geographical Information System (GIS). In total, six maps were considered to determine a suitable location for settlements, namely topography, soil, geology, land cover/land use, a regional spatial planning pattern map, and an earthquake vulnerability map. The results showed that in medium earthquake-prone areas, the suitable land area which are available for settlement was 90.25 km2 (46.36% of the total land area available - 194.68 km2). Whereas in highly earthquake-prone areas, the suitable and available land area was 528.11 km2 (70.25% of the total land area in the high vulnerability zone - 751.81 km2). The research proved that AHP and GIS integration is very effective and robust for mapping land suitability in earthquake-prone areas. The results of the analysis can be used by planners to prioritize settlement development in the Sukabumi regency. The methodology developed is recommended to be applied in selecting locations for settlements in other parts of Indonesia.

Opis:
In this paper, we extend the analytic hierarchy process (AHP) method and the Atanassov’s intuitionistic fuzzy set (IFS) into the intuitionistic fuzzy analytic hierarchy process (IFAHP) with application in ship system risk estimation. In the safety engineering, risk estimation is in practice confronted with difficulties connected with shortage of data. In such cases, we have to rely on subjective estimations made by persons with practical knowledge in the field of interest, i.e. experts. However, in some realistic situations, the decision makers might be reluctant or unable to assign the crisp evaluation values to the comparison judgments due to his/her limited knowledge. In other words, there is a certain degree of hesitancy in human cognition and his judgment. Taking advantages of IFSs in dealing with ambiguity and uncertainty into account, the IFAHP can be used to handle with the subjective preferences of experts, who may have insufficient knowledge of the problem domain or uncertainty in assigning the evaluation values to the objects considered. This paper also develops a new knowledge-based ranking method to derive the priority vector of the hierarchy. An illustrative example of the propulsion risk estimation of container carriers operating on the North Atlantic line is given to show the applicability and effectiveness of the proposed method.

In Morocco, solid household waste is often disposed of in open air in unsuitable sites, causing adverse effects on humans and the environment. In the province of Settat, there are eight uncontrolled landfills. The present study aimed to determine the most suitable sites from an environmental and economic point of view to ensure good management on a regional scale. The investigation involved a combination of a multi-criteria method (the AHP analytical hierarchy process) and a GIS geographic information system (ArcGIS) with ten criteria: distance from the ground water, water surfaces, drilling, settlements, forests, roads, highway, land use, slope, and elevation. The suitability map showed that about 18.5% of the study area is suitable for installing a sanitary landfill.

Ukształtowany na terytorium regionu system osadniczy stanowi w geografii społecznoekonomicznej jeden z głównych czynników rozwoju. Szczególną rolę w systemie tym odgrywają miasta,których znaczenie rozpatrywać można z różnych perspektyw. W artykule z perspektywy przestrzennejbadaniom poddano hierarchię i relacje miast w województwie lubuskim. Spośród narzędzi statystycznychwykorzystano regułę wielkości i kolejności Zipfa oraz model grawitacji. Analizę przeprowadzono na podstawie danych za rok 2015. Wyniki badań empirycznych wskazują, że pomimo podobnego zagęszczeniamiast w województwie lubuskim jak ogólnie w kraju system miast w regionie charakteryzuje wyraźnaspecyfika. Obok dwóch największych miast pełniących funkcje regionalne i ponadregionalne, którymi sąZielona Góra i Gorzów Wlkp., duże znaczenie ma problematyka funkcjonowania małych i średnich miastw województwie.
In socio-economic geography any regional settlement system makes one of its majorfactors of development. It is towns that play a specific role in this system, the meaning of which canbe approached from different perspectives. This paper focuses on the hierarchies and relationshipsbetween towns in the Province of Lubuskie seen from the spatial point of view. The volume and sequence rule of Zipf ’s law as well as the gravitation model have been used as the statistical tools. Thedata valid as in 2015 were accounted for in the analysis. Results from the empirical studies show thatdespite a similar urban density in Lubuskie Province and generally across Poland, the town system in theregion is visibly specific. Apart from two largest cities playing a regional and cross-regional function,i.e. Zielona Góra and Gorzów Wlkp., the issue of how small and middle-sized towns function in theprovince comes to the fore.

Opis:
The paper presents a problem of a transition predicates construction in hierarchical concurrent state oriented notation. The notation, called statechart diagrams or state machine, serves as a very convenient formalism for specification of a complex behavior of the embedded systems control unit. The controller specified in this way is discrete, deterministic and synchronous system which operates on binary values and can be implemented in programmable devices as a digital circuit. Well designed controller has conflict-free transitions and its concurrent transitions should be independent. In order to meet this requirements transition predicates must be pairwise both orthogonal and non-implicative. Computational complexities of the problems is equal to classic clique problem. The paper also suggests some statecharts syntactic structures solving these problems.
