Development of systems for DX solutions using operation logs

Development of systems for DX solutions using operation logs

TOKYO, February 25, 2025 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed the world's first* "Operation Log-driven Development Technology" for the development of systems that facilitate and accelerate digital transformation (DX). The new technology enhances system operation management and maintenance by visualizing and sharing know-how derived from operator experience and knowledge stored in system operation logs.

In modern society, the labor shortage resulting from the declining birthrate and aging population and the passing down of technology know-how have become major issues. In particular, in the management and maintenance of public infrastructure, daily operation is maintained by monitoring and controlling large amounts of signals from various sensors. However, when an abnormality occurs due to equipment failure or abnormal weather, it is necessary to identify the cause at an early stage and implement countermeasures.

However, deciding which measures to deploy often depends on the judgment of experienced operators and experts. As the number of extreme weather events resulting from climate change increases, and with a declining population and aging facilities, there is an urgent need to provide systems for DX solutions that enhance operational and maintenance capabilities by leveraging the experience and knowledge accumulated by such veteran operators and experts.

In the early stages of developing these kinds of systems, interviews with operators and experts are conducted and requirements are analyzed to clarify the requirements and conditions that the new systems must meet. However, interviews alone make it difficult to grasp the detail of operations that may have been forgotten or overlooked, or tacit knowledge that the operators themselves are not conscious of. In addition, since it may take an enormous amount of time to interview all operators of a particular system, the number of interviews has to be limited, making it difficult to gather comprehensive information.

The Operation Log-driven Development Technology Mitsubishi Electric has now developed can visualize system operation logs and can automatically extract and visualize multiple operation activities that have an identical objective by analyzing the relationship between signals monitored by different operators. The use of this technology makes it easier to share among related parties the kinds of know-how that cannot be ascertained by interviews alone, for example by determining and analyzing the actual state of operations and providing a visualization of tacit knowledge. This allows the transfer of technology more efficiently and requirements to be analyzed more accurately.

In addition, by building an early prototype of the systems for DX solutions on the basis of the requirements analysis and using this technology to repeatedly improve these through the accessing of operation logs, the time required to develop these systems can be significantly shortened.

Details of the development results will be announced on March 3 at INTERACTION 2025 being held in Japan from March 2 to March 4.
