AI Case Study

"To address these issues, Hitachi developed AI which provides appropriate work orders based on an understanding of demand fluctuation and on-site kaizen activity derived from big data accumulated daily in business systems. By integrating the AI into business systems, it will become possible to incorporate on-site kaizen activities or employee ideas while flexibly responding to changes in work conditions or demand fluctuations to realize efficient operations. Main features of the AI are as follows:

"1. Understanding of human ideas and kaizen, and translating this to work orders

Although workers on-site conduct tasks based on work orders issued by business systems analyzing big data such as those related to work details or results, in order to conduct the tasks efficiently, workers also devise and implement new approaches and kaizen drawing from experience. The AI automatically analyzes the outcome of these new approaches, and selects processes which produce better results and applies it to the next work order. By understanding and applying the ideas of on-site workers and their kaizen activity to work instructions on a daily basis, it is possible to create an environment where humans and AI mutually cooperate to continuously raise efficiency.

2. Automatically select appropriate data from big data and flexibly respond to demand fluctuation

When developing conventional business systems, expected busy or off-peak season related demand fluctuations are taken into consideration in the design but this has not been able to accommodate for short periods of bad weather or sudden increases in demand. The AI automatically selects and analyses data similar to the actual work conditions of the day from past big data on work detail, work volume and weather, to provide appropriate work instructions in response to short period of bad weather or sudden changes in demand.

3. Quickly intake various forms of big data

Business systems accumulate big data in various alphanumeric forms including symbols, such as amount, time and product codes. Thus, in order to analyze this data with AI, it was necessary to have a domain expert in the business task pre-analyze the data, making data analysis even more time-consuming. The AI analyzes the statistical distribution of the data, and by automatically pre-categorizing the data notation format, enables new data to be integrated quickly without assignment by a human interpreter. As a result, it becomes possible to automatically incorporate daily kaizen by employees or demand fluctuation into the system to produce appropriate and timely work instructions."
