Quality control apparatus and control method of the same, and recording medium recorded with quality control program
First Claim
1. A quality control apparatus which controls a manufacturing process in order to manufacture products of predetermined quality, the apparatus comprising:
- a storing module which collects measurement data measured by multiple measuring devices disposed in a manufacturing process and stores the collected measurement data along with measured time or collected time; and
an associating module which associates the measurement data of the multiple measuring devices with each other in consideration of dead time generated between the measuring devices at measured time or collected time.

Abstract
Various items of data collected at different process steps are associated on production sites where traceability is hard to conduct. A quality control apparatus controls a manufacturing process in order to manufacture products of predetermined quality, including a data storing part which collects measurement data measured by multiple devices disposed in a manufacturing process and stores the collected measurement data along with measured time or collected time; and a scheduler which associates the measurement data of the devices with each other in consideration of dead time generated between the devices at measured time or collected time.

6. A quality control apparatus which controls a manufacturing process in order to manufacture products of predetermined quality, the apparatus comprising:
-
a storing module which collects and stores intermediate characteristic data of an intermediate product measured by an intermediate characteristic measuring device and final characteristic data of a completed product measured by a final characteristic measuring device;
a specification limit generating module which generates an intermediate characteristic specification limit set to the intermediate characteristic measuring device based on a data distribution of the final characteristic data stored in the storing module and a final characteristic specification limit set to the final characteristic measuring device; and
a specification limit setting control module which controls the intermediate characteristic measuring device so as to set the generated specification limit generated by the specification limit generating module. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A quality control apparatus which controls a control target device disposed in a manufacturing process in order to manufacture products of predetermined quality, the apparatus comprising:
-
a storing module which collects and stores a set value of a control value set as a target value to the control target device, control data that is a measurement value of the control value measured by the control target device with respect to the set value, and intermediate characteristic data of an intermediate product measured by an intermediate characteristic measuring device;
an intermediate characteristic estimating module which estimates a variation in a data distribution of the intermediate characteristic data when the set value of the control value stored in the storing module is switched;
a defective number estimating module which estimates a number of defectives based on a variation in the data distribution of the intermediate characteristic data estimated by the intermediate characteristic estimating module and an intermediate characteristic specification limit;
a switching amount deciding module which decides a switching amount for the set value of the control value so that the number of defectives estimated by the defective number estimating module is the minimum; and
a control switching module which switches the set value of the control value of the control target device based on the switching amount decided by the switching amount deciding module. - View Dependent Claims (14, 15, 16, 17, 18)
