Fujitsu Boosts Efficiency of Manufacturing Processes
Going forward, Fujitsu will further strengthen its collaboration with Intel in the IoT field, creating new solutions and making them available to customers.
In May 2015, Fujitsu and Intel reached an agreement to collaborate in building a more optimal systems environment by combining Fujitsu's cutting-edge technology with the Intel® IoT Gateway, a blueprint for interoperable IoT solutions, with the aim of providing high-value IoT solutions. As a field trial of this collaboration, since May 2015 the companies have been working to improve manufacturing process efficiency through factory visualization at Shimane Fujitsu.
At Shimane Fujitsu, when products are detected to have faults in the functionality testing performed on the manufacturing line, they are sent to the repair area to receive a thorough diagnosis, analysis, and repair of the fault before being shipped, but there are sometimes cases in which the fault cannot be reproduced in the repair process. In these situations, it is necessary to conduct a comprehensive analysis of the work done by the worker involved in the functionality testing process who detected the fault, the tools used, and the status of the product being tested, in order to make clear the reason for the fault detection. Because real-time visualization of the task status of the functionality testing process was previously insufficient, however, it was impossible to identify the cause or implement policies to prevent reoccurrence, resulting in an excess of products being repaired.
In addition, in the repair process, information, such as the location of the product to be repaired in the repair line, whether or not it was held up, and each product's shipping deadline information, was not made visible in real time. This meant that it was not possible to separate out products that should be prioritized, causing them to miss planned shipping deadlines, often resulting in costs for arranging additional shipping trucks.
To visualize the functionality testing process, using Fujitsu Laboratories Ltd.'s image-processing technology that raises the recognition ratio for text in images, along with a framework that shortens the development of applications that use the technology, worker task status is recorded on video, along with the error code (a code that displays the content of the fault) displayed on the screen of the product to be repaired. This video is aggregated through the Intel® IoT Gateway, for process visualization, by performing analytical image processing. As a result, in addition to improving the efficiency of error code aggregation, it is now possible to find trends in detected faults, and to efficiently analyze the circumstances when a fault was detected. By using the results of this analysis to limit misdetection of faults, Fujitsu will be able to reduce excess product repairs.
