Multi-agent blind model and its application to regional eco-environmental quality assessment

Abstract

Through denoting each expert as an agent and viewing a multiple criteria decision-making as a synthesis problem of aggregating experts' ratings, a multi-agent blind model (MABM) is developed for regional ecoenvironmental quality assessment. In this model, the ratings of the evaluated object under an index, given by expert group, are first utilized to construct a series of blind numbers. In general, each index will correspond to different blind numbers. On the basis of aggregating index weights, the rank score in the form of a blind number is obtained for the evaluated object. Then, by means of calculating expected value of the above blind number, its rank score is further converted into a crisp value. By way of comparing the expected value with classification standards, eco-environmental quality of the evaluated sample could be identified successfully in the end. As a case, the MABM is used to evaluate the eco-environmental quality of Chaohu Lake basin. Study result shows that the MABM is a useful model for regional eco-environmental quality assessment.

Extension theory-based modeling for purified terephthalic acid solvent system

“…Extension theory [8]- [10] is a relatively new mathematical technique, which applies the formal model to expand the possibility of matter and explore the innovative principle for contradiction problems in the real world, and has been successfully used in economics [11], management [12], decision-making [13] and control field [14]. In addition, the artificial neural network [15]- [17] has apparent advantages in study, association memory and searching optimal solution, which has been widely used in automatic control, optimized computation as well as other aspects.…”

Dynamic assessment on regional eco-environmental quality using AHP-statistics model —A case study of Chaohu Lake Basin

“…It is well known that regional eco-environmental quality assessment is an important measure to realize all-sided environmental management, harmonize the relationship between socio-economic development and eco-environmental protection and fulfill the sustainable development of regional economy, society and environment (Kuo and Chiu, 2006;Laura et al, 2006;Li, 2006a;Mario and Giuseppe, 2001;Zhang et al, 2006). Up to now, many researches have been done on comprehensive assessment of eco-environmental quality (Li, 2006b;Li et al, 2005;Wang, 2002;Wu et al, 2006;Zheng and Wang, 2000).…”
