Process management device for visualizing production status

A process management method that visualizes a production status of a plurality of product pieces being manufactured through multiple work processes using a work process management chart of a two-dimensional coordinate system including a time axis representing work time in each work process and a process axis representing transition of the work processes, the process management method comprising:

• receiving various acquired information including operation data of a production facility corresponding to each of the work processes as well as request instruction information from a manager;
• extracting, from the operation data, a work start time that is a time when processing is started and a work end time that is a time when processing is completed in each of the work processes for each product piece and generating connection line arrangement data that is display data obtained by arranging a first mark representing the work start time and a second mark representing the work end time in each of the work processes at their respective coordinate positions on the work process management chart;
• generating, for each of the plurality of product pieces, first display data by drawing, on the basis of the connection line arrangement data, a work time line connecting the first mark and the second mark of one piece of product, both marks being arranged on each time axis of a first work process and a second work process following the first work process among the multiple work processes and by drawing, on the basis of the connection line arrangement data, a conveyance time line connecting the second mark in the first work process and the first mark in the second work process for the one piece of product;
• adjusting, when the request instruction information for the first display data is inputted, a representation method of the work process management chart displayed based on the first display data in accordance with the request instruction information and thus generating second display data being the display data of the work process management chart obtained by visualizing the work process management chart with the adjusted representation method of the work process management chart different from the representation method of the work process management chart displayed based on the first display data;
• and
• outputting the first display data as the display data for outputting while the request instruction information for the first display data is not inputted and outputting the second display data as the display data for outputting when the request instruction information for the first display data is inputted,
• wherein a characteristic value of a characteristic part is extracted as a judgment index on whether the production status is good or bad from the work process management chart displayed based on the first display data or the second display data and, as the display data for outputting, the display data of the work process management chart with a discrimination sign for assisting assessment of the production status added is outputted, on the basis of an allowable value predetermined for each characteristic value, to the characteristic part of the work process management chart displayed based on the first display data or the second display data.

A non-transitory storage medium storing a program to make a computer execute processes for visualizing a production status of a plurality of product pieces being manufactured through multiple work processes using a work process management chart of a two-dimensional coordinate system including a time axis representing work time in each work process and a process axis representing transition of the work processes, the processes comprising:

• receiving various acquired information including operation data of a production facility corresponding to each of the work processes as well as request instruction information from a manager;
• extracting, from the operation data of the production facility corresponding to each of the work processes, a work start time that is a time when processing is started and a work end time that is a time when processing is completed in each of the work processes for each product piece and generating connection line arrangement data that is display data obtained by arranging a first mark representing the work start time and a second mark representing the work end time in each of the work processes at their respective coordinate positions on the work process management chart;
• generating, for each of the plurality of product pieces, first display data by drawing, on the basis of the connection line arrangement data, a work time line connecting the first mark and the second mark of one piece of product, both marks being arranged on each time axis of a first work process and a second work process following the first work process among the multiple work processes and by drawing, on the basis of the connection line arrangement data, a conveyance time line connecting the second mark in the first work process and the first mark in the second work process for the one piece of product;
• adjusting, when the manager's request instruction information for the first display data is inputted, a representation method of the work process management chart displayed based on the first display data in accordance with the request instruction information and thus generating second display data being the display data of the work process management chart obtained by visualizing the work process management chart with the adjusted representation method of the work process management chart different from the representation method of the work process management chart displayed based on the first display data;
• and
• outputting the first display data as the display data for outputting while the request instruction information for the first display data is not inputted and outputting the second display data as the display data for outputting when the request instruction information for the first display data is inputted,
• wherein a characteristic value of a characteristic part is extracted as a judgment index on whether the production status is good or bad from the work process management chart displayed based on the first display data or the second display data and, as the display data for outputting, the display data of the work process management chart with a discrimination sign for assisting assessment of the production status added is outputted, on the basis of an allowable value predetermined for each characteristic value, to the characteristic part of the work process management chart displayed based on the first display data or the second display data.
