Display method, display device, and recording medium

A display device comprising:

• a memory having executable instructions stored thereon;
• and a processor coupled to the memory, wherein the processor is configured to execute the instructions:
• to identify, for each product to be manufactured in a certain manufacturing unit, a starting time or an ending time or both of processing performed on the product by a first apparatus and a starting time or an ending time or both of processing performed on the product by a second apparatus based on log information of the first apparatus and log information of the second apparatus, the first and the second apparatuses being included in a manufacturing line, the second apparatus performing the processing after the processing performed by the first apparatus;
• to place, on a first temporal axis, the starting time or the ending time or both identified for each product in the first apparatus, the first temporal axis indicating the starting time or the ending time or both of the processing performed on each product by the first apparatus;
• place, on a second temporal axis, the starting time or the ending time or both identified for each product in the second apparatus, the second temporal axis indicating the starting time or the ending time or both of the processing performed on each product by the second apparatus, the second temporal axis being in parallel with the first temporal axis;
• and place, for each product, a line that connects a point placed on the first temporal axis and another point placed on the second temporal axis;
• and
• to display an area interposed between a first line and a second line such that the area is in a visible state and overlap with the placed lines, the first line connecting points placed on the first temporal axis and the second temporal axis, the point placed on the first temporal axis indicating a time at which the processing performed on a first product by the first apparatus is to start or end, the point placed on the second temporal axis indicating another time at which the processing performed on the first product by the second apparatus is to start or end, the times being times when the first product is normally processed by both of the first and the second apparatuses, the first product being manufactured first in the certain manufacturing unit, the second line connecting other points placed on the first temporal axis and the second temporal axis, the point placed on the first temporal axis indicating a time at which the processing performed on a second product by the first apparatus is to start or end, the point placed on the second temporal axis indicating another time at which the processing performed on the second product by the second apparatus is to start or end, the times being times when all of the products included in the certain manufacturing unit are normally processed by both of the first and the second apparatuses, the second product being manufactured last in the certain manufacturing unit.

A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a display process comprising:

• identifying, for each product to be manufactured in a certain manufacturing unit, a starting time or an ending time or both of processing performed on the product by a first apparatus and a starting time or an ending time or both of processing performed on the product by a second apparatus based on log information of the first apparatus and log information of the second apparatus, the first and the second apparatuses being included in a manufacturing line, the second apparatus performing the processing after the processing performed by the first apparatus;
• placing, on a first temporal axis, the starting time or the ending time or both identified for each product in the first apparatus, the first temporal axis indicating the starting time or the ending time or both of the processing performed on each product by the first apparatus;
• placing, on a second temporal axis, the starting time or the ending time or both identified for each product in the second apparatus, the second temporal axis indicating the starting time or the ending time or both of the processing performed on each product by the second apparatus, the second temporal axis being in parallel with the first temporal axis;
• placing, for each product, a line that connects a point placed on the first temporal axis and another point placed on the second temporal axis;
• and
• displaying an area interposed between a first line and a second line such that the area is in a visible state and overlaps with the placed lines, the first line connecting points placed on the first temporal axis and the second temporal axis, the point placed on the first temporal axis indicating a time at which the processing performed on a first product by the first apparatus is to start or end, the point placed on the second temporal axis indicating another time at which the processing performed on the first product by the second apparatus is to start or end, the times being times when the first product is normally processed by both of the first and the second apparatuses, the first product being manufactured first in the certain manufacturing unit, the second line connecting other points placed on the first temporal axis and the second temporal axis, the point placed on the first temporal axis indicating a time at which the processing performed on a second product by the first apparatus is to start or end, the point placed on the second temporal axis indicating another time at which the processing performed on the second product by the second apparatus is to start or end, the times being times when all of the products included in the certain manufacturing unit are normally processed by both of the first and the second apparatuses, the second product being manufactured last in the certain manufacturing unit.
