Gh. Huang et al., INCORPORATION OF INEXACT DYNAMIC OPTIMIZATION WITH FUZZY RELATION ANALYSIS FOR INTEGRATED CLIMATE-CHANGE IMPACT STUDY, Journal of environmental management, 48(1), 1996, pp. 45-68
A study of integrated climate change impact assessment and adaptation
study for agricultural and timbering activities in Mackenzie Basin, Ca
nada, was conducted through development/application of an inexact dyna
mic optimization (IDO) model that can reflect complex system features
and a related fuzzy relation analysis (FRA) method that is useful for
comprehensive assessment of impact patterns. The IDO approach allows u
ncertain information to be effectively communicated into the optimizat
ion process. The resulting solutions are presented as intervals which
can be directly interpreted to generate adaptation alternatives. The m
ethod also has low computational requirements since its solution algor
ithm does not lead to more complicated intermediate submodels. Through
this IDO approach, uncertain, dynamic and interactive features of the
study system can be effectively reflected. The FRA method provides a
viable means for synthetic analysis of general climate change impact p
attern based on the IDO outputs. The method is helpful for obtaining i
nsight into the interrelations between different system components. Th
e results indicate that complex natures of climate change impacts have
been effectively reflected through the proposed approaches. Generally
, temporal variations of land characteristics and thus land use activi
ties exist due to changes in climatic, economic and environmental cond
itions. (C) 1996 Academic Press Limited
