PURPOSE: A method for purchasing a scientific industry material is provided to enable a user to buy an industry material having a user-wanted function by making an industry material buyer open an industry material product list on the Internet when an industry material user records the industry material product list in an operator server system. CONSTITUTION: A user judges a product standard of an industry material adapted to an experimentation to be performed, records the product standard in an operator server system, and requests an industry material purchase to a buyer(100). The buyer decides an industry material purchase and selects an industry material information search or not(105). If the buyer selects the search, the operator server system displays industry material information possessed by a seller stored in an industry material database to the buyer through a web window(110). The buyer decides the lowest price purchasing method(115). The buyer applies the purchasing method to the operator server system, opens a product standard of an industry material selected by the user, and induces a reverse auction participation(120). The buyer judges whether a forecasted cost necessary for buying the material is publicized(125). The buyer publicizes the forecasted cost(130). The lowest price purchasing method is progressed(135). The buyer selects a seller who suggested the lowest price(140). The operator server system informs industry material purchase contents to a financial institution(145). If the seller mounts the industry material, the buyer checks the mounting state and informs a mounting completion to the operator server system, and the operator server system informs the mounting completion to the financial institution(150). The financial institution supplies the price of the industry material to the seller(155). The user deposits the price to the financial institution(160). |
