Manufacturing Work Analysis Using Product-Worker Time Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analysis techniques, such as those described in Japanese Patent Laying-Open No. 2012-22602, fail to allow users to easily determine whether a decrease in work efficiency has occurred in manufacturing processes without prior familiarity with running charts.
Innovation Solution
An analysis device and method that acquire and analyze data on product and worker time zones in manufacturing processes, determining factors that decrease work efficiency by comparing these zones and providing graphical and textual feedback to users, allowing for easy recognition of inefficiencies.

1Loss of information
If running charts are used to visualize work situations, then work efficiency can be analyzed, but users must be familiar with the chart to determine efficiency decreases
Solution Approach 1:
The system automatically provides feedback by comparing the product's time zone with the worker's time zone and determining whether efficiency-decreasing factors have occurred. This automated feedback mechanism eliminates the need for users to manually interpret running charts, directly resolving the contradiction between information availability and ease of recognition.
Solution Approach 2:
The analysis device acts as an intermediary between the raw time zone data and the user. It processes the relationship between product and worker time zones, automatically determining efficiency issues and presenting results in an easily recognizable format, thus mediating between complex data and user comprehension.
2Measurement precision
If detailed time zone data is collected and analyzed, then work efficiency factors can be identified, but system complexity increases
Solution Approach 1:
The system extracts only the essential relationship data between product time zones and worker time zones, focusing on the critical comparison needed to determine efficiency factors. By extracting and analyzing only the necessary temporal relationship information, the system achieves precise measurement without requiring overly complex infrastructure.

AI summary
An analysis device includes: a first acquisition unit that acquires data indicating a first time zone in which each product stays in each of a plurality of processes; a second acquisition unit that acquires data indicating a second time zone in which a worker stays in each of the plurality of processes; an analyzer that analyzes a work situation for each product in each of the plurality of processes; and a providing unit that provides an analysis result. The analyzer determines, on the basis of a relationship between the first time zone and the second time zone in a period for analysis of a process for analysis, whether or not a factor that decreases work efficiency has occurred in the period for analysis of the process for analysis.
