It is desirable to install the raw material 6 such as in the vicinity of the processing machine to which the raw material 6 is first conveyed. The raw material 6 may be preliminarily printed with an identification symbol, an identification number, a type name, etc. capable of identifying the type and the like. The record input operation may be performed by preparing in advance a production schedule and the like in which the house name number and at least one member number and the like are associated with the raw material 6, and referring to the production schedule and the like.

On the hard disk drive or the like of the registration client 11, a form for inputting the house name number and the member number as a record of an appropriate production sequence is read out on the main memory of the registration client 11 and displayed on the screen of the display means. The production sequence database 8 can be displayed and the form after inputting is updated as the production sequence data table.
An input program that can be stored in the main memory can be stored in the main memory so that it can be read.

For inputting a record, addition to the lowest production sequence, insertion into an appropriate production sequence, correction of an already-input record, advancement of an already-input record to a higher production sequence or to a lower production sequence. This includes moving back and deleting already entered records. In this case, the equipment processing data table is searched based on the inputted house name number by an input program or the like, all corresponding member numbers are displayed in a list on the screen of the display means, and the member number is selected by the input means. If it is possible to input, there is an advantage that erroneous input can be prevented.

The master sequencer 12 is based on a control data table in which, for example, part of equipment processing data is associated with member numbers such as "1001", "1002", "1005" as shown in FIG. Thus, the automatic transfer line 2, the first processing machine 3, the second processing machine 4, and the third processing machine 5 can be controlled.
