Abstract
In Japan the Government has been trying to supply as many new houses as possible. In consequence the number of houses exceeds the number of household in every Prefecture. Every “region” has been recently trying to realize higher level ideas, such as regional climate, identity and tradition, in planning a regional housing policy. Whereas we are still in short of efficient planning theories and techniques to estimate the mechanism of housing demand and housing supply in a region. So it seems necessary to achieve efficient theories with which housing planning covering a certain area of demand and supply market in a region can be improve. In this study we develop five mathematical planning models, which can support us to estimate such housing demand and to plan reasonable housing supply in a region. Each model is applied to some regions and studied its operationality, efficiency and problems. First, we examine Government's theories and techniques which have been used for housing planning since World War II and then study present planning theories and techniques used for the Government's housing planning in prefectural levels. Then we have developed five models such as ①a model which can be used for planning maintenance program of a regional housing stock from a view of economic approach, ②a model which can be used for studying or planning regional distribution of lot area or floor space of houses,③a model which can be used for estimating relation between house types and household types in a region, ④a model which can describe household movement in a region caused by new housing supply, ⑤a model which can propose a most efficient housing supply type by adopting Linear Programming. In developing models, we try to utilize existing statistics, such as Housing Survey of Japan, Population Census of Japan and others, and some administrative materials in order to in-crease operationality of models for applying to actual regional housing planning. This study will be continued next year and we report this as Part I.
