Production Status Visualization with Flexible Process Charts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Gantt charts are inflexible and difficult to adjust to user-specific representation methods, limiting their effectiveness in managing production status based on display area restrictions and manager-specific needs.
Innovation Solution
A process management device utilizing a two-dimensional coordinate system with a time axis and process axis to visualize production status, allowing for flexible representation through a data input unit, control unit, and display unit that adjusts display data based on manager requests, including work time and conveyance time lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional Gantt chart is used to visualize production status, then the production status can be represented, but the representation method is uniformly limited and cannot be adjusted according to display area restrictions or manager-specific needs
Solution Approach 1:
The control unit dynamically changes the representation method of the work process management chart based on manager requests. It can switch between different visualization modes (e.g., conventional Gantt chart, fishbone diagram, other formats) and adjust display parameters such as time scale, process axis configuration, and information density to match display area restrictions and specific management needs, making the system adaptable rather than static
Solution Approach 2:
The system allows changing multiple parameters of the chart representation including time scale, process axis arrangement, information detail level, and visualization format. By adjusting these parameters, the same underlying data can be presented in different ways suitable for different scenarios, display areas, and managerial preferences without requiring multiple separate systems
2Area of stationary object
If the representation method is adjusted to match display area restrictions, then the chart can be displayed in limited space, but the original uniform representation method loses its simplicity
Solution Approach 1:
The control unit provides dynamic scaling and compression capabilities that automatically adjust the chart to fit the available display area. When the display area is limited, the system can compress the time axis, reduce information detail, or switch to a more compact visualization format, and expand when more space is available, maintaining optimal utilization without manual intervention
3Ease of operation
If multiple representation methods are supported, then manager-specific needs can be met, but the system becomes more complex to operate
Solution Approach 1:
The control unit automatically selects and switches between different representation methods based on manager requests without requiring complex manual configuration. The system stores multiple representation templates and can quickly switch between them or automatically select the most appropriate one for the current situation, reducing the operational burden on managers while providing diverse representation options
Data Source
AI summary
A process management device includes: a data input unit to input acquired information including operation data of a production facility as well as request instruction information; a control unit to output first display data of the work process management chart which includes work time lines showing work times by length and conveyance time lines showing conveyance times by inclination, both lines being arranged on the process management chart on the basis of the operation data, and serves as display data of the work process management chart, and when requested, to output second display data of the work process management chart obtained by visualizing the production status visualized by the first display data with a representation method of the work process management chart different from that of the work process management chart displayed based on the first display data; and a display unit to display the display data for outputting.
