A material requirements planning method of calculating supplier material supply aims at resolving the problems of lot-size material issuing methods on production schedule systems in the manufacturing industry. A material requirements planning server of an enterprise end server simulates material issuing operations during a stock-out period, and executes timely delivery of particular parts or components, utilizing as-needed delivery rather than lot-size delivery. The disclosed method includes at least the steps of: capturing data through an Enterprise Resource Planning (ERP) server, receiving and storing a promise order from the supplier end on the material requirements planning server, simulating with the material requirements planning server to determine whether the promise order can meet material requirements on the shortage list, releasing an original build order from stock-outs, generating data of the build order to the Enterprise Resource Planning (ERP) server and implementing an available to promise (ATP) to directly deliver materials through the Enterprise Resource Planning (ERP) server.
