for the successful tree establishment, an evaluation of land suitability is necessary.in this paper, we demonstrate how to implement fuzzy classification of land suitability in agis environment for afforestation with juglans regia in gharnaveh watershed of golestanprovince in iran. juglans regia is one of the most important agro-forestry species in manyrural parts of iran. relevant criteria for...

Multi-criteria Evaluation (MCE) is increasingly being used in the assessment of natural resource management options which involve complex ecological, economic and social outcomes and interactions. This paper draws on the results of research experiences and reviews MCE applications to identify methodological issues with conducting MCE and future research possibilities. Some of the key issues tha...

supplier selection is a multi-criteria problem. this study proposes a hybrid model for supporting the suppliers’ selection and ranking. this research is a two-stage model designed to fully rank the suppliers where each supplier has multiple inputs and outputs. first, the supplier evaluation problem is formulated by data envelopment analysis (dea), since the regarded decision deals with uncertai...

in recent decades, necessity to protect environment has been a serious concern for all people and international communities. in appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife. as a resu...

in last decades, the skillful planning of land resources has become a major issue for rural development. the development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. fuzzy logic is preferred to boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can the...

the evaluation and selection of recommender systems is a difficult decision making process. this difficulty is partially due to the large diversity of published evaluation criteria in addition to lack of standardized methods of evaluation. as such, a systematic methodology is needed that explicitly considers multiple, possibly conflicting metrics and assists decision makers to evaluate and find...

the use of value engineering (ve) methodology in construction industry has grown significantly, mainly in view of its extensive benefits. the main task in evaluation phase of ve workshop is to assess alternative ideas, proposed for each function. this phase of ve, hence, could be deemed as a multi criteria decision making (mcdm) problem. this paper presents a fuzzy decision support system (dss)...

When evaluating power system expansion scenarios there is a need to take into consideration range of measurable and non-measurable impacts. Measurable impacts are fixed variable production costs and, recently, external costs. Nonmeasurable include public attitude certain energy technology investor's risk in achieving the expected profit. Public has large, sometimes essential impact on decision-...

One of the most important applications of GIS is the display and analysis of data to support the process of environmental decision-making. A decision can be defined as a choice between alternatives, where the alternatives may be different actions, locations, objects, and the like. For example, one might need to choose which is the best location for a hazardous waste facility, or perhaps identif...
