Abstract

Provided is a management system associated with a manufacturing line including one or more facilities. Each of the facilities is configured to process each workpiece according to order information. The management system includes: a collecting means for collecting event information about a process that takes place in each of the facilities; a classifying means for classifying, on the basis of a generation source and content of each piece of event information, the event information collected by the collecting means, into sets of event information generated due to the same workpiece; a generation means for generating data which represents process circumstances for each workpiece on the basis of the event information belonging to each of the sets classified by the classifying means; and a visualizing means for visualizing process progression circumstances for each workpiece processed according to the order information, on the basis of the data generated by the generating means.

First claim

1 . A management system associated with a manufacturing line including one or a plurality of facilities, each of the one or plurality of facilities being configured to process individual workpieces according to order information including designation of a type of manufacturing targets and designation of the number of manufacturing targets, the management system comprising:
a collecting means for collecting event information regarding a process generated in each of the one or plurality of facilities; a classifying means for classifying the event information collected by the collecting means into a set of event information generated due to the same workpiece on the basis of a generation source and content of each piece of event information; a generation means for generating data indicating a process status of each workpiece on the basis of event information belonging to each of sets classified by the classification means; and a visualizing means for visualizing a progress status of a process for each workpiece to be processed according to the order information on the basis of the data generated by the generation means.

2 . The management system according to claim 1 , wherein the classifying means classifies the collected event information according to a configuration of the one or the plurality of facilities in the manufacturing line.

3 . The management system according to claim 1 , wherein, when the classifying means receives event information having the same content from the same generation source a plurality of times, the classifying means classifies each piece of the event information into event information caused by different workpieces.

4 . The management system according to claim 1 , wherein the visualizing means reproduces processing progress of each workpiece on the manufacturing line on a plane that is defined by an axis associated with process and an axis of time.

5 . The management system according to claim 1 , wherein the visualizing means displays a list of event information classified into a set corresponding to a selected workpiece.

6 . The management system according to claim 1 , wherein the generation means specifies an order number to which the set classified by the classifying means belongs and a workpiece number within the order on the basis of information on a time included in the order information.

7 . The management system according to claim 1 ,
wherein the collecting means further collects field information that is acquired in the one or the plurality of facilities, and the generation means executes a process of associating the collected field information with a corresponding workpiece.

8 . The management system according to claim 7 , wherein the visualizing means displays the associated field information in response to selection of the workpiece.

9 . The management system according to claim 7 , further comprising:
a monitoring means for comparing pieces of field information associated with a plurality of workpieces in a predetermined facility with each other to monitor a trend that can occur in the facility.

10 . A management method in a manufacturing line including one or a plurality of facilities, each of the one or plurality of facilities being configured to process individual workpieces according to order information including designation of a type of manufacturing targets and designation of the number of manufacturing targets, the management method comprising:
a step of collecting event information regarding a process generated in each of the one or plurality of facilities; a step of classifying the event information collected in the collecting step into a set of event information generated due to the same workpiece on the basis of a generation source and content of each piece of event information; a step of generating data indicating a process status of each workpiece on the basis of event information belonging to each of sets classified in the classifying step; and a step of visualizing a progress status of a process for each workpiece to be processed according to the order information on the basis of the data generated in the generating step.

11 . A management system associated with a manufacturing line including one or a plurality of facilities, each of the one or plurality of facilities being configured to process individual workpieces according to order information including designation of a type of manufacturing targets and designation of the number of manufacturing targets, the management system comprising:
a collecting means for collecting event information generated in each of the one or plurality of facilities; a calculation means for calculating a time at which a process is actually performed on each workpiece in each of the one or plurality of facilities on the basis of the event information collected by the collecting means; and a determination means for determining an allocation ratio that is defined as a key performance indicator on the basis of a time required for a process according to the order information and the time calculated by the calculation means.

12 . The management system according to claim 11 , wherein the calculation means calculates a time when the process has been actually performed from an integrated value of a period from start of the process to completion of the process in a target facility, for each of one or a plurality of workpieces processed according to the same order information.

13 . The management system according to claim 11 , wherein the determination means determines another indicator that is defined as a key performance indicator, in addition to the allocation ratio, and the management system further comprises:
a display means for displaying a plurality of indicators determined by the determination means side by side or in an overlapping manner.

14 . The management system according to claim 13 ,
wherein the management system is associated with a plurality of manufacturing lines, and the display means displays indicators calculated for each of the plurality of manufacturing lines side by side or in an overlapping manner.

15 . A management method in a manufacturing line including one or a plurality of facilities, each of the one or plurality of facilities being configured to process an individual workpiece according to order information including designation of a type of manufacturing targets and designation of the number of manufacturing targets, the management method comprising:
a step of collecting event information generated in each of the one or plurality of facilities; a step of calculating a time at which a process is actually performed on each workpiece in each of the one or plurality of facilities on the basis of the event information collected in the collection step; and a step of determining an allocation ratio that is defined as a key performance indicator on the basis of a time required for a process according to the order information and the time calculated in the calculating step.

16 . The management system according to claim 2 , wherein the visualizing means reproduces processing progress of each workpiece on the manufacturing line on a plane that is defined by an axis associated with process and an axis of time.

17 . The management system according to claim 2 , wherein the visualizing means displays a list of event information classified into a set corresponding to a selected workpiece.

18 . The management system according to claim 2 , wherein the generation means specifies an order number to which the set classified by the classi
