Abstract: PURPOSE: An ATP(Available To Promise) calculation service method is provided to make a rapid and definite calculation of the ATP for an ordered PCB(Printed Circuit Board) over the Internet. CONSTITUTION: The method comprises several steps. A user transmits a manufacturing order of a PCB to a server(S20), and then an ATP calculation module of the server checks order conditions and the time limit for delivery(S21). The ATP calculation module calculates the raw material input time and the manufacturing time for each lot in the manufacturing process corresponding to the order conditions by interfacing with an ATP support module(S22, S23). The ATP calculation module calculates an estimated manufacturing completion date for the ordered PCB by adding the input time and the manufacturing time(S24), and calculates the ATP by adding a delivery time to the estimated manufacturing completion date(S25). The server compares the calculated ATP with the requested time limit for delivery. If the ATP is earlier than the requested time limit(S26), the server notifies the user that the requested order is possible(S27), and otherwise, the server asks the user if the requested time limit can be adjusted(S28).
