Process control system
First Claim
1. A process control system for controlling a production process in which a plurality of processes are connected hierarchically, the plurality of processes including at least a pair of a previous process and a next process, the previous process producing first products and the next process producing second products using the first products as parts, comprising:
- a data generating system that generates at least first data regarding the first products produced in the previous process and second data regarding the parts used in the next process, the first data and the second data being related to link information indicating a link between the previous process and the next process; and
a data storing system that stores data generated by the data generating system, wherein the first data regarding the first products includes data indicating a name of the previous process, data indicating a start time of producing of the previous process, data indicating a finish time of the producing of the previous process, data indicating a time at which the first products are carried out of the previous process, and data concerning defective products in the previous process, and wherein the second data regarding the parts includes data indicating a name of the next process, data indicating a start time of use of the parts in the next process, data indicating a finish time of use of the parts in the next process, data indicating a time at which the parts are carried in the next process, and data concerning defective parts in the next process.

Abstract
A process control system for controlling a production process includes a data generating system that generates at least first data regarding first products produced in a previous process and second data regarding parts used in a next process. The first data and the second data are related to link information indicating a link between the previous process and the second process. The process control system further includes a data storing system that stores data generated by the data generating system.

10. A computer readable storage medium for storing management data used for a process control system for controlling a production process including a plurality of processes, the plurality of process including at least a pair of a current process and a next process successively connected in the production process, the management data having a data structure comprising:
-
object identifying data that is provided for an object group, and is used to identify the object group uniquely;
first data regarding the current process in which products are collected as an object group; and
second data regarding the next process in which objects are pulled out of the object group, wherein the first data and the second data are related to their corresponding object identifying data, wherein the first data, the second data, and the corresponding object identifying data are stored as a single file in the process control system, and wherein the management data is used in the process control system to perform the controlling of the production process. - View Dependent Claims (11, 12, 13, 14, 15, 16)
