Once local expert knowledge regarding the harvesting of various non-timber forest products (NTFPs) is lost, it is difficult to recover. We investigated whether the knowledge of expert forest harvesters can be used to determine the habitat distribution and harvesting sites of three popular edible wild ferns, i.e., ostrich fern (Matteuccia struthiopteris), bracken (Pteridium aquilinum), and royal...

Taking timely measures for management of the natural resources requires knowledge of the dynamic environment and land use practices in the rapidly changing postindustrial world. We used the SLUETH urban growth modeling and a multi-criteria evaluation (MCE) technique to predict and allocate land available to landfill as affected by the dynamics of the urban growth. The city is Gorgan, the capita...

Multi-car elevator (MCE for short) systems have been receiving increasing attention these days. An MCE has two or more cars in one shaft. It is difficult to control MCEs by using algorithms developed for single-car elevator systems, because MCEs need to avoid collision of the cars of the same shaft. In this paper, we propose an algorithm to control MCE systems, and show the effectiveness of our...

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...

Dike-pond is a unique agricultural landscape type in the Pearl River Delta region of China, which has significance for maintenance ecological balance. In recent years, urbanization China developed rapidly, and dike-ponds have been extensively occupied, reducing their regulation ability threatening regional security. Taking Shunde District Foshan as an example, based on remote sensing images fro...

This paper focuses on the integration of GIS and an extension of the analytical hierarchy process (AHP) using quantifier-guided ordered weighted averaging (OWA) procedure. AHP_OWA is a multicriteria combination operator. The nature of the AHP_OWA depends on some parameters, which are expressed by means of fuzzy linguistic quantifiers. By changing the linguistic terms, AHP_OWA can generate a wid...

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...
