The social environment relating to distribution system of the fishery products has been extensively changed in reorganization move of production center markets as well as consuming place markets and under strict administration for installing speed restraint device. To cope with such conditions, research on simulation technique and development of simulation program were worked out for distribution cost, transportation cost・time, CO_2 and so on after reorganization of the markets, based on the investigation about current distribution conditions in the region concerned. This study aims at providing such data and information as required for planning efficient measures to meet any change of distribution conditions, in comparison of several evaluation indices which may regulate efficiency degree in before and after reorganized markets of the fishery products.
