A process design support system 2 that supports process design and creates process data, and a data analysis system 4 that analyzes measurement values output from the device 1 to detect abnormalities early.
A lot scheduling system 5 is provided for creating a lot schedule for effectively utilizing the equipment used in the production line. Further, the production management device 20 has a measurement value database 9 that stores the measurement values obtained by the device 1 in the measurement process, and a process database 8 that stores the process data regarding the progress status of the lot in the manufacturing process. There is. The lot progress management system 3 in the production management apparatus 20 is composed of a resident program, and the lot scheduling system 5 and the data analysis system 4 are composed of a non-resident program.

The purpose is to provide.

[0008]

In order to achieve the above-mentioned object, the production control apparatus of the present invention has a manufacturing process completion signal or measurement from the lot progress control means when a manufacturing process or a measurement process in a production line is completed. The process completion signal is output, and the operation of the function in the production control device is started or the operation state is changed based on the signal.

Specifically, when the manufacturing process on the production line is completed, the lot progress management means outputs a manufacturing process completion signal to the lot scheduling means, and based on the manufacturing process completion signal, the lot scheduling means is informed of the process schedule. When the correction process is started or the measurement process on the production line is completed, the lot progress management unit outputs a measurement process completion signal to the data analysis unit, and the measurement data analysis unit analyzes the measurement data based on the measurement process completion signal. Is to start.

[0010]

With the configuration of the present invention, when the manufacturing process on the production line is completed, the lot progress management means outputs a manufacturing process completion signal to the lot scheduling means. The lot scheduling means is activated by receiving the manufacturing process completion signal and starts correction of the process schedule of the production line. When the measurement process is completed, the lot progress management means outputs a measurement process completion signal to the data analysis means. The data analysis means is activated by receiving the measurement process completion signal, and starts the analysis of the measurement data obtained in the measurement process. Therefore, when the manufacturing process does not proceed as planned, the lot scheduling means can immediately perform the rescheduling, and the data analysis means can be automatically activated upon completion of the measurement process.
