Floods represent one of the most severe natural disasters threatening development human society worldwide, including in Thailand. In recent decades, Chaiyaphum province has experienced a problem with flooding almost every year. particular, flood 2010 caused property damage 495 million Baht, more than 322,000 persons were affected, and approximately 1046.4 km2 productive agricultural area was af...

Quantitative methods of spatial conservation prioritization have traditionally been applied to issues in conservation biology and reserve design, though their use in other types of natural resource management is growing. The utility maximization problem is one form of a covering problem where multiple criteria can represent the expected social benefits of conservation action. This approach allo...

A common application of raster-based geographic information systems (GIS) is as an aid in multi-criteria, multi-objective land-use decision problems. However, as the cell resolution increases by reducing cell size, the number of rows and columns in the raster representation also increases. The size of raster representations of land-use problems is often a determining factor in the type of metho...

Different conflicting objectives are used in urban land use optimization problems. The maximization of social benefit is one the important Many researchers have different methods to measure benefits optimization. Studies show that there no established method allocation game. Against this background, study aims (a) identify appropriate indicators as a benefit, and (b) propose composite index Bas...

ABSTRACT This paper describes the Active Response GIS (AR/GIS) for resource planning and land­ allocation deliberation. AR/GIS is an integrated system which combines GIS and electronic meeting software. This combination provides the voting, information organization, and brainstorming of an electronic meeting system, and supports interaction with geographic data sets. The AR/GIS system can impro...

unplanned urban development imposes significant pressure on land resources and land use structures and brings about many negative socio-economic and environmental consequences. therefore, comprehensive studies should be applied to support urban land use management in the world and especially in developing countries. in iran, like many other developing countries, urban development is fast and of...

distribution centers (dcs) play important role in maintaining the uninterrupted flow of goods and materials between the manufacturers and their customers.this paper proposes a mathematical model as the bi-objective capacitated multi-vehicle allocation of customers to distribution centers. an evolutionary algorithm named non-dominated sorting ant colony optimization (nsaco) is used as the optimi...
