Abstract
In this paper, sales of every day of a certain apparel store were investigated for the consumer's demand forecasting model construction, and the meteorological factor such as the temperature was investigated at the same time. And, consumer's demand forecasting model is constructed by using meteorological factor in statistically clarifying the relation between these. Concretely, the fuzzy reasoning model to whom demand is forecast by trying the analysis of sales of every day and the relation between the number of visitors and the meteorological factor by applying a decentralized analysis, selecting the meteorological factor from this analytical result, and using the obtained factor is constructed.
