Abstract. The analysis of mining-induced sinkholes occurrence is a very important issue as far as the spatial development optimization is concerned. Research conducted for this paper was focussed on examining the applicability of GIS and the associated AHP method (analytic hierarchy process) for estimating the risk of discontinuous deformation occurrence on the surface. Qualitative factors were accounted for in the sinkhole risk assessment, thus creating bases for the research. These elements play an important role in the process of sinkholes formation; however, they were not used in prediction models. Another assumption lay in minimizing the number of variables in the model. Accordingly, the most important qualitative and quantitative risk factors were finally selected on the basis of whether the risk of cave-ins occurrence on the surface could be calculated. The results of the estimation of potential sinkhole zones were verified. The locations of actual and high-risk potential discontinuous deformation were compared. The congruence between predicted values and the actual observations of sinkholes was very high. The results of research presented prove the necessity to evaluate sinkhole hazards in view of qualitative factors.

Abstract. The analysis of mining-induced sinkholes occurrence is a very important problem as far as the spatial development optimization is concerned. Research conducted within this paper was oriented to revealing the applicability of GIS and the associated AHD method for estimating the risk of discontinuous deformation occurrence on the surface. The qualitative factors were accounted for in the sinkhole risk assessment, thus creating bases for the research. These elements play an important role in the process of sinkholes formation; however they were not used in prediction models. Another assumption lied in minimizing the number of variables in the model. Accordingly, the most important qualitative and quantitative risk factors were finally selected, on the basis of which the risk of cave-ins occurrence on the surface could be calculated. The results of estimations of zones with sinkholes potential were verified. The places of actual and high-risk potential discontinuous deformations were compared. The congruence between predicted values and actual observations of sinkholes was very high. The results of presented research prove the necessity to evaluate the sinkhole hazard in view of qualitative factors.

Ships create a large amount of pollutions to marine and coastal environment where its pollutants have negative effects to human and maritime habitat. Depending on the nature of ship-generated waste, rules and regulations determine discharging procedures. This paper focuses on evaluating of potential hazards of ship-generated wastes on the environment whether it may be discharged into the sea or disposed of on port facilities. Thus, marine and costal environmental effects can be discussed analytically to improve human and ecological health. To achieve this purpose, analytic hierarchy process (AHP) extended with interval type-2 fuzzy sets (IT2FSs) is used. While AHP method is used for prioritizing the potential ship- generated waste, the IT2FSs deal with uncertainty and vagueness in the process of obtaining expert decision. Beside assessment of the environmental impacts, the paper contributes to enhance coastal and marine environmental awareness with respect to the ship-generated waste.

Hierarchy Process

The Analytic hierarchy process (AHP) is a popular method for solving multi-criteria problems. However, the problem of the adequacy of the AHP method is not solved. Opponents of the Analytic hierarchy process believe that the AHP as a whole is erroneous and cannot be applied in practice. Proponents of the method believe that the disadvantages of the method are compensated by a simple measurement procedure. In this paper, a modification of the AHP method is proposed. A mathematical model of measurement is formulated, which contains a built-in mechanism for checking adequacy. moreover, the measurement method is preserved, and the calculation algorithm becomes even simpler. The fact is that the Analytic hierarchy process is based on the assumption that the scale of relations can be obtained by pairwise comparison using numerical judgments based on the absolute scale of numbers. Fechner’s psychophysical law is considered as a justification for the existence of the scale of relations. But there are not one, but two psychophysical laws. The existence of two psychophysical laws is a problem of psychophysics. This problem can be solved by the rating method. To overcome the disadvantages of the Analytic hierarchy process, it is also proposed to use the rating method. The use of the rating method makes it possible to use the fundamental scale of the AHP method. As an example, the problem is solved using the traditional AHP scale.

In a high-tech backend semiconductor business where a market environment changes sharply and requires competitiveness of high technology, one of the most important criteria is to establish an optimal strategy for outsourcing development so a firm can achieve a sustainable competitive advantage. Many studies have investigated sustainable and successful strategies for the selection and management of outsourcing suppliers, whereas, this study focuses mainly on analyzing the most affecting factor for outsourcing development in the perspective of dynamic capability by using the Delphi Analytic Hierarchy Process (AHP) method. For the analysis of affecting factors, 4 dimensions are defined: technology, organization, environment, and process. The research result shows that the sustainability of the productive skill in the technology dimension is adopted as the most affecting factor for outsourcing development among the defined 4 dimensions of an outsourcing supplier’s capability. With this research, a high-tech firm can measure the level of each dimension and each factor in developing outsourcing service providers. Then the firm can develop an appropriate outsourcing provider who contributes to the firm’s sustainable competitive advantage. This study also provides a practical and strategic framework of a high-tech firm’s outsourcing development in variable market situations and changeable conditions of transaction.

Hybrid ground source heat pump (GSHP) systems which utilize capillary radiant ceiling are promising to provide a better building comfort while reducing energy consumption. We have developed a GSHP model and an analytic hierarchy process (AHP) method for evaluating the system feasibility. The hybrid GSHP system provides heating/cooling for an office in Wuhan, China. A conventional HVAC system – water chiller + gas boiler (WB) system was also simulated. The results showed that the hybrid system would provide a better indoor comfort and remains at the thermal comfort class I, and the hybrid system would incur a 14.5% lower cost but would provide 43.2% more energy saving. The hybrid GSHP system could reduce 20.23 tons of CO2 emission, while 1.39 tons more SO2, 0.39 tons more NOx and 9.70 tons more Ash emissions could be produced. Overall, the hybrid system performance evaluation result (SPER) was 0.966, and the WB system was 0.746. These SPERs were quantified system evaluation results calculated using the AHP method, which have considered the impacts of the various factors – economic cost, energy saving and environmental impact. The hybrid GSHP system is more adaptable than the WB system and has a good application prospect in this climate region.
