Visualization system

A display apparatus for displaying a manufacturing status of a product manufactured through a plurality of manufacturing steps in order, comprising:

• a first creation section configured to create, for each product manufacturing unit, a line segment connecting a start time or an end time of a first step on a time axis of the first step to a start time or an end time of a second step subsequent to the first step on a time axis of the second step in parallel with the time axis of the first step;
• a second creation section configured to identify, based on a change log of a step characteristic factor at each manufacturing step, any change in step characteristic factor observed at each of the first step and the second step, and to create a display object representing a magnitude of the identified change in step characteristic factor or including a region representing an attribute of the changed step characteristic factor;
• and
• a display control section configured to cause the display apparatus to display a line segment representing the time axis of each manufacturing step, the line segment created by the first creation section, and the display object associated with each manufacturing step, and to place the display object associated with the first step and the display object associated with the second step over positions of the start times or the end times on the time axes of their associated steps,
• wherein the display control section is configured to place information about defective rate of each product manufacturing unit on a time axis in parallel with the time axis of the manufacturing step and in relation to a last step of the plurality of manufacturing steps.

A non-transitory computer readable medium including a computer readable program for visualizing a manufacturing status of a product manufactured through a plurality of manufacturing steps in order, the program comprising instructions which, when executed by a computer, cause the computer to perform:

• first processing of creating, for each product manufacturing unit, a line segment connecting a start time or an end time of a first step on a time axis of the first step to a start time or an end time of a second step subsequent to the first step on a time axis of the second step in parallel with the time axis of the first step;
• second processing of identifying, based on a change log of a step characteristic factor at each manufacturing step, any change in step characteristic factor observed at each of the first step and the second step, and creating a display object representing a magnitude of the identified change in step characteristic factor or including a region representing an attribute of the changed step characteristic factor;
• and
• third processing of causing a display apparatus to display a line segment representing the time axis of each manufacturing step, the line segment created by the first processing, and the display object associated with each manufacturing step, and placing the display object associated with the first step and the display object associated with the second step over positions of the start times or the end times on the time axes of their associated steps,
• wherein the third processing causes to place information about defective rate of each product manufacturing unit on a time axis in parallel with the time axis of the manufacturing step and in relation to a last step of the plurality of manufacturing steps.
