Abstract
In order to evaluate agricultural production not only from economics but also from energy and load on environment, new indices using entropy were proposed, in which the concept of resource physics was applied. Poultry production was selected as a target system. Simulation of economics, energy and entropy was performed for different regions and housing types to demonstrate the new evaluation technique. Open type housing in warm climate was predicted to be most desirable from the view point of load on environment. However, for a colder climate the predicted desirable housing type was enclosed from the view point of production. The proposed indices which are combination of the load on environment and production, economics demonstrated the possibility to estimate a production system fitting to the region.HomePageKeywords: entropy, Iayer, housing system, evaluation
