SUMMARY Purpose: study optimization location-allocation of emergency shelter for Earthquake after destructive earthquake disaster, so as to prevent or reduce the damage caused by the earthquake and its secondary disasters, to guide the resettlement and reconstruction of post-disaster. Methods: basis on GIS, by applying the location-allocation optimization of P-center model of geographical space...

Economic growth in China is accompanied by many problems, such as rapid deterioration of the environment and a sharp decline in the area of arable land. China’s current land-use planning system fails to deal with these problems, especially at the regional level. The lack of sustainable spatial allocation at regional level has become a pressing problem. This article aims to: (1) analyze the reas...

land use optimization is one of the suitable methods for soil conservation. the present research with objective of land use optimization for soil erosion minimization and pure income maximization was conducted in the part of taleghan watershed which comprises 80427.23 ha in area. to achieve this propose, area, erosion rate and net income value of each land uses according to requiring standards ...

Disturbance and deforestation have profound ecological and socioeconomic effects on tropical forests, but their diffuse patterns are difficult to detect and quantify at regional scales. We expanded the Carnegie forest damage detection system to show that, between 1999 and 2005, disturbance and deforestation rates throughout the Peruvian Amazon averaged 632 square kilometers per year and 645 squ...

A general framework for a combined land use and water management is described. An optimization problem is formulated that combines combinatorial and spatial characteristics. The aim of the planning is to maximize economic benefit, while minimizing water extraction and transportation cost under ecological constraints. A genetic algorithm is employed endowed with a new neighborhood operator. This...

The western “panhandle” region of Florida experienced greater development in the years 2000-2010 than the previous 40 years and greater than nearly all other parts of the United States. One reason is the fact that much of the coastal land in the peninsula of Florida is already developed whereas much of the Panhandle is empty. Another reason is the fact that increasing temperatures and less seve...

Many portfolio optimization problems deal with allocation of assets which carry a relatively high market price. Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...
