Abstract

A visualization method of manufacturing status is implemented by a computer that visualizes manufacturing status of a product manufactured sequentially by a plurality of processes. The visualization method includes: placing a first symbol that indicates a start and an end of the manufacturing of the product in a first process of the processes on a first temporal axis of the first process with a width corresponding to a time taken from the start to the end of the manufacturing in the first process, and a second symbol that indicates a start and an end of the manufacturing of the product in a second process following the first process on a second temporal axis of the second process with a width corresponding to a time taken from the start to the end of the manufacturing in the second process, the first and the second temporal axes extending in a same direction.

forming a first line that connects a part indicating the start of the manufacturing in the first symbol placed on the first temporal axis of the first process and a part indicating the start of the manufacturing in the second symbol placed on the second temporal axis of the second process, and a second line that connects another part indicating the end of the manufacturing in the first symbol and another part indicating the end of the manufacturing in the second symbol, using the processor;

outputting lines indicating the first and the second temporal axes, the first symbol, and the second symbol, using the processor; and

outputting an area defined by the first symbol, the first line, the second symbol, and the second line in a visually recognizable color, using the processor.

3. The visualization method of manufacturing status according to claim 1, wherein, when the manufacturing of the product proceeds following respective standard manufacturing times of the processes or apparatuses, distances between the temporal axes are adjusted such that upper sides of areas or first bands become a straight line at the outputting the area or displaying transition, using the processor.

4. The visualization method of manufacturing status according to claim 3, wherein

at the outputting the area, the area with an extended upper side is output in a visually recognizable color, the upper side is extended such that a line that is perpendicular to a temporal axis of a last process and extended from the part indicating the end of the manufacturing in the last process intersects another temporal axis provided next to the temporal axis of the last process, the distance between the temporal axis of the last process and the other temporal axis being set based on the standard manufacturing time of the last process, using the processor, or

at the displaying the transition, the first band with an extended upper side is formed, the upper side is extended such that a line that is perpendicular to a temporal axis of a last apparatus and extended from the part indicating the end of the processing period of the last apparatus intersects another temporal axis provided next to the temporal axis of the last apparatus, the distance between the temporal axis of the last apparatus and the other temporal axis being set based on the standard manufacturing time of the last apparatus, using the processor.

5. The visualization method of manufacturing status according to claim 1, wherein, at the outputting the area or displaying transition, a stripe pattern is further displayed on a background for each product, the stripe pattern indicating a first stripe in each process or the areas when the manufacturing of the product proceeds following respective standard manufacturing times of the processes or apparatuses, using the processor.

6. The visualization method of manufacturing status according to claim 1, wherein, at the outputting the area or displaying transition, an image that indicates an event or an error occurring in a process or an apparatus is further displayed on the corresponding temporal axis, using the processor.

7. The visualization method of manufacturing status according to claim 1, wherein, at the outputting the area or displaying transition, the area or a first band is further displayed in different colors depending on types of the product, using the processor.

8. The visualization method of manufacturing status according to claim 1, further including:

counting number of areas or first bands that intersect a line extending perpendicular to each temporal axis, using the processor; and

outputting information of the number of areas or first bands being equal to or larger than a certain value when the number of areas or first bands is equal to or larger than the certain value, using the processor.

2. A display method of manufacturing status, the display method being implemented using a computer, the display method comprising:

identifying a processing period and a waiting period of a first apparatus included in a manufacturing line and a processing period and a waiting period of a second apparatus included in the manufacturing line and performing processing after processing in the first apparatus, based on log information about the processing in the first apparatus and log information about the processing in the second apparatus, using a processor;

placing the identified processing period and waiting period of the first apparatus on a first temporal axis that indicates a change in processing and waiting periods of the first apparatus, and the identified processing period and waiting period of the second apparatus on a second temporal axis that is in parallel with the first temporal axis and indicates a change in processing and waiting periods of the second apparatus, using the processor;

forming a first band that connects the processing periods of a manufacturing product common between the first apparatus and the second apparatus, and a second band that connects the waiting periods of the manufacturing product common between the first apparatus and the second apparatus, each of the waiting periods following the processing of the manufacturing product, using the processor; and

displaying transition of the processing periods and the waiting periods as stripes of different bands, using the processor.

9. A display device comprising:

a memory; and

a processor coupled to the memory, wherein the processor configured
