The PROMETHEE is a significant method for evaluating alternatives with respect to criteria in multi-criteria decision-making problems. It is characterized by many types of preference functions that are used for assigning the differences between alternatives in judgements. This paper proposes a preference of green suppliers using the PROMETHEE under the usual criterion preference functions. Comp...

Kinmen National Park is the only battle memorial-themed natural resource conservation park in Taiwan. With the rapid growth in tourism, Kinmen National Park faces the challenge of managing with the resulting environmental impact. For this study, we adopted the tourism ecological footprint (TEF) and tourism ecological capacity (TEC) to evaluate the ecological conditions of Kinmen National Park f...

Pedotransfer functions (PTFs) are physical–mathematical models which allow estimating soil hydraulic properties from soil data. In the absence of direct measurements, they represent a valuable tool for providing agro-ecological models with soil input estimations, whose accuracy is currently a key issue, especially in fieldand regional-scale modelling which rely on soil information databases. Th...

In the recent past there has been concern to address the declining trends and deteriorating ecological elements and their functions in productive agricultural landscapes. The efforts to revive the ecological functions needs multiple scale approach, which include scientific understanding, time dependent restorative activities and incorporation of wisdom of the stakeholders. Conservation initiati...

development of remote sensing (rs) and gis techniques and that of landscape metrics in the late 1980s have caused to introduce a new dimension in the landscape ecology arena (the relationship between spatial patterns and ecological processes). however, scale dependence of some of landscape metrics and rs systems of different spatial resolution has resulted in particular attention into selection...

Some scientists are interesting to study in area of harvested ecological modelling. The harvested population dynamics is more realistic than other ecological models. In the present paper, some of the Lotka-Volterra predator-prey models have been considered. In the said models, existing species are harvested by constant or variable growth rates. The behavior of their solutions has been analyzed ...

The goal of the fuzzy diatoms models is to use the advancement of the fuzzy theory and with predictive modelling to predict the outcome of given condition of diatoms. Fuzzy modelling depends from many factors, mainly by the shape of the membership functions, similarity metrics and above all the operation between the fuzzy sets – the fuzzy operators. In this paper we introduce new fuzzy operator...

Ecosystem modelling is increasingly used to explore ecosystem-level effects of changing environmental conditions and management actions. For coral reefs there has been increasing interest in recent decades in the use of ecosystem models for evaluating the effects of fishing and the efficacy of marine protected areas. However, ecosystem models that integrate physical forcings, biogeochemical and...

to determine if there is a gender difference in the resource consumption activities of students in central mindanao university, a philippine state university, an ecological foot printing study was conducted in august 2014. consumption data from 380 student respondents were gathered using a survey questionnaire. a web-based software created by the global footprint network was used to convert the...
