A MULTI-OBJECTIVE INDUSTRY ALLOCATION MODEL

ABSTRACT Industry allocation problem is one of the most crucial problems in developed countries, especially in Japan. The authors have developed a multi-sector, multi-region optimization model with multi-objective criteria in order to obtain desirable industrial allocation patterns of future Japan. Factors taken into the model are those of economy, population, environment, cargo transport, land, water, and labor force. Various algorithms have been developed so far for searching the most desirable solution for a decision maker from among a set of non-inferior solutions. The authors propose a new efficient interactive searching algorithm, which the authors employ to determine respective solution or scenario which is the most desirable for each author. The scenarios thus obtained are evaluated in comparison with the present industry location pattern and with the alternative scenario proposed by the Ministry of International Trade and Industry. The results demonstrate that the multi-objective optimization technique introduces a new dimension in the field of industry allocation planning.
