Modelos de fragilidades ambientais compreendem, de maneira geral, a avaliação de n aspectos (ou fatores) relativos às características locais, usualmente tratadas por técnicos de diferentes áreas constituintes de uma equipe multidisciplinar. Porém a definição dos n aspectos por parte da equipe nem sempre acontece de forma unânime, não raro ocorrendo, no início do processo de avaliação, dúvidas sobre o quanto realmente cada aspecto ou fator (indicador) apresenta-se significativo dentro do modelo de avaliação. Como estudo de caso, foi realizada a sensibilidade das ponderações dos fatores que compõem o método multicriterial AHP (Analytic Hierarchy Process), aplicado na região da bacia hidrográfica do Alto Uruguai. A metodologia consistiu na ponderação sistemática de cada fator constituinte do modelo para posterior consideração quanto a sua influência em relação ao conjunto dos fatores, proporcionando uma avaliação quanto a sua eficácia na identificação de pesos dos fatores em cenários que mostram maior discriminância no conjunto, além de apresentar alternativas na composição dos pesos. Assim, a partir dos resultados da análise, configura-se a importância da realização do estudo da sensibilidade em modelos de fragilidade ambiental aplicados à bacia hidrográfica.Palavras-chave: Análise de sensibilidade; avaliação ambiental; multicritério. AbstractSensitiveness of model to environmental fragilities to multicriterial weighting: physical aspects of watershed of the Alto Uruguay. Environmental fragilities models comprise, generally, the evaluation of n criteria (or factors) on local characteristics, usually handled by technicians from different areas in a multidisciplinary team. However, definition of n aspects by team does not always happen unanimously, often occurring early in the evaluation process doubts whether every aspect or indicator is in fact significant within the evaluation model. As a case study, it was performed the sensitivity of weighting factors that comprising the multicriterial method AHP (Analytic Hierarchy Process) applied to the basin of the Alto Uruguay region. After evaluating the multicriterial method, we applied the sensitiveness analysis to improve the weighting process. Therefore, from the results of this analysis, it sets up the importance of the study of sensitiveness of environmental fragility models for the watershed better understanding.Keywords: Sensitiveness analysis; environmental assessment; multicriterial weighting.

The growth of competition puts new demands on enterprises, in particular to the range of products and its quality. Assortment policy is now one of the factors of enterprise competitiveness. All decisions related to the formation of assortment policy at the enterprise have a significant impact on the economic and competitive position of the enterprise. Therefore, the problems of analysis and optimization of the range of the enterprise, the formation of its assortment policy are the focus of researchers. At present, a significant number of methods of analysis and range management have been developed. The choice of a specific path in the formation of the assortment strategy is determined by many internal and external factors. The decision to be made should be the best in terms of increasing profits, increasing sales and reducing the complexity of manufacturing products. But decisions about changes in the range and the definition of the range strategy are made in conditions of uncertainty and risk. In such conditions, multicriteria methods that minimize risk and create a basis for making optimal management decisions are useful. Of great interest are multicriteria methods that can take into account criteria of different nature, both quantitative and qualitative. One of the most famous in the world and the most effective method used to solve multi-criteria decision-making problems is the analytic hierarchy process. The study was conducted in collaboration with a polymer film company. The article proposes the use of the analytic hierarchy process to decide on the need for further production of some types of film. Criteria for comparison of films and decision-making are defined, interrogation of experts is carried out. The practical results of the research are presented: the priorities of each type of film studied are determined. Recommendations are given to the management of the enterprise: what types of films should not be continued to be made. The results of the study demonstrate the possibility of improving the decision-making procedure for optimizing the product range.

In this paper we introduce a definition of consistency of the judgement matrix in the fuzzy Analytic Hierarchy Process (AHP) and give a general expression of all fuzzy weights under the condition of consistency. Finally, based on our discussion, the geometric average method is suggested for fuzzy weights calculation in the practical decision-making situation.

Old community renovation is an important project about the livelihood of people, and the nation is catching the work. This paper firstly analyzes the definition of livable community and the livable condition of old community renovation, establishing the livable index system and the livable evaluation model of old community renovation. The paper employs Analytic Hierarchy Process to determine the index weighs and takes use of Fuzzy Comprehensive Evaluation Method to analyze the case.
