“…The fuzzy set theory provides a wider framework than the classic set theory and has contributed to the capability for reflecting the real world (Ertugrul and Tus 2007). Finally, the fuzzy analytic hierarchy process (FAHP), which has the advantage of handling the inherent uncertainly and imprecision of the human decision-making process, was selected for deriving the weight assigned to each factor and subclass.…”

Floods, the most common natural hazard in the world, cause serious loss in terms of lives, buildings, and infrastructures. As a consequence, the need for flood risk assessment has become critical. Using a semi-quantitative model and fuzzy analytic hierarchy process (FAHP) weighting approach, this paper assessed flood risk in the Dongting Lake region, Hunan Province, Central China, an area where flood hazards frequently occur. The model was designed using spatial multi-criteria analysis (SMCA) techniques in a Geographic Information System (GIS). A GIS database of indicators for the evaluation of hazard and vulnerability was created. Each indicator was analyzed, standardized, and weighted; after which, the weights of the indicators were combined to obtain the final flood risk index map. Using the flood risk index, the study area was classified into five categories of flood risk: very low, low, medium, high, and very high. The high and very high risk zones are mainly concentrated in the northern and central plains. The results obtained can provide useful information for decision makers and insurance companies.

“…Their role is significant when applied to complex phenomena not easily described by traditional mathematical methods, especially when the goal is to find a good approximate solution (Bojadziev & Bojadziev, 1998). Fuzzy sets theory providing a more widely frame than classic sets theory, has been contributing to capability of reflecting real world (Ertuğrul & Tuş, 2007). Modeling using fuzzy sets has proven to be an effective way for formulating decision problems where the information available is subjective and imprecise (Zimmermann, 1992).…”

Pla nt species selection is a multi-criteria evaluation decision and has a strategic importance for many companies. The conventional methods for plant species selection are inadequate for dealing with the imprecise or vague nature of linguistic assessment. To overcome this difficulty, fuzzy multi-criteria decision-making methods are proposed. The aim of this study is to use the fuzzy technique for order preference by similarity to ideal solution (F.TOPSIS) methods for the selection of plant species in mine reclamation plan. Plant type selection and planting to protect the environment and the reclamation of the mine are some of the most important solutions. Therefore, the objective of the current research study is to choose the proper plant types for reclamation of Sarcheshmeh Copper Mine using Fuzzy-topsis method. In this regard, primarily, surrounding area of Sarcheshmeh copper mine, one of the world's 10 biggest copper mine which is located near Kerman city of Iran, are surveyed, to choose the best plant type for reclamation of disturbance area. With this respect, based on reclamation plan, primary criteria were consisted of kinds of post mining land use, climate, and nature of soil. Comparison matrixes were then obtained based on experts' opinion and plant types were subsequently prioritized using the Fuzzy Topsis method. Secondary factors considered through the analysis were as follows: pers pective of the region, resistance against disease and insects, stre ngth and method of growth, availability to plant type, economic efficiency, protection of soil, storing water, and prevention of pollution. Finally, suitable plant types in the mining perimeter were prioritized as: Amygdalus scoparia, Tamarix, Pistachio Wild, Ephedra, Astragalus, Salsola, respectively. Keywords: mine reclamation, plan t type selection, Sarcheshmeh Copper Mine, Fuzzy TOPSIS Wybór gatunków roślin jest decyzją podejmowaną w oparciu o wiele kryteriów i stanowi poważne wyzwanie strategiczne dla wielu firm. Konwencjonalne metody wyboru gatunków roślin okazują się niewystarczające w przypadku nieprecyzyjnej oceny i nie w pełni zdefiniowanych określeń językowych. W celu przezwyciężenia tych trudności, zaproponowano wielo-kryterialną metodę decyzyjną wykorzystującą logikę rozmytą. Celem tego opracowania jest ukazanie zastosowania podejścia rozmytego do uzyskania kolejnych przybliżeń do rozwiązania idealnego (F.TOPSIS) przy wyborze odpowiednich gatunków roślin do użycia w projekcie rekultywacji terenów kopalni. Wybór gatunków roślin i ich kultywacja dla zapewnienia ochrony środowiska i projektu rekultywacji terenu pogórniczego to bardzo ważne zagadnienia. Głównym celem obecnego studium jest wybór odpowiednich gatunków roślin do wykorzystania projekcie rekultywacji terenów kopalni miedzi Sarcheshmeh z wykorzystaniem metod logiki rozmytej TOPSIS. W pierwszym rzędzie przeprowadzono badania gruntów wokół kopalni miedzi Sarchesmeh, w pobliżu miejscowości Kerman w Iranie (jednej z dziesięciu największych na świecie kopalni miedzi) w celu wyboru najleps...

“…Such a set is characterized by a membership (characteristic) function, which assigns to each object a grade of membership ranging between zero and one. With different daily decision making problems of diverse intensity, the results can be misleading if the fuzziness of human decision making is not taken into account (Tsaur et al, 2002) Fuzzy sets theory providing a more widely frame than classic sets theory, has been contributing to capability of reflecting real world (Ertugrul & Tus, 2007). Fuzzy sets and fuzzy logic are powerful mathematical tools for modeling: uncertain systems in industry, nature and humanity; and facilitators for common-sense reasoning in decision making in the absence of complete and precise information.…”
