Abstract
In marketing, it is an important matter to promote “when” and “what kind of products” to consumers. In this research, we attempted to construct a model in which the purchasing intervals of five categories of goods,“ fried side dish”,“ yoghurt”,“ milk”,“ sweet buns” and“ eggs” of each consumer in the supermarket follow the Weibull distribution. From the shape parameters and scale parameters obtained from the analytical model, for each of the five product categories, the purchasing tendency for each consumer was clarified. Based on the consumer’s purchasing trend that we made clear, we presented the possibility of improvement for the product category that promotes for each consumer.
