PURPOSE: To shorten the work time required for the completion of input work and to improve the precision of actual results of production.

CONSTITUTION: Production condition information of respective production processes are inputted to a storage part of a host computer 1 through input/ output terminals 4A, 4B, 4C, and 4D installed in respective production process parts and an intra-enterprise communication network with input devices, and all the production processes are controlled based on these input production condition information. In this production control method, the host computer 1 discriminates whether input production condition information of each production process is correct or not and transfers the discrimination result to input/ output terminals 4A, to 4D to display it on a part of the input menu display picture, ana input production condition information is stored in the storage part of the host computer 1 if it is correct. History information of past production process conditions in respective production processes is displayed in a prescribed position on the display picture of one of input/output terminals 4A to 4D together with input production condition information.
