Unlike industrial products, purchase prices for agricultural and marine products change sometimes, and thus selling prices for the agricultural and marine products change. Also, the agricultural and marine products are living products and have short shelf life, and depreciation thereof due to spoilage can occur. Therefore, a depreciation pattern by the lapse of time has to be reflected to stock management, and purchasing and selling price changes have to be reflected to and be in tandem with the stock management, comprehensively. Also, stock values and profit estimation are analyzed and information for establishing a sales plan is provided. Unlike industrial products, the agricultural and marine products are living products and the values of the agricultural and marine products rapidly decrease by the lapse of time. Accordingly, it is important to assist wholesalers to sell out the products without stock. Especially, it is important that how rapid products are sold out by a product purchasing unit. Therefore, it is important to assist in selling out products in various methods based on a diagnosis and prediction function for stock values by the lapse of time and an analysis function for purchasing patterns of existing customers. |
