 Much of the global enterprise which has achieved rapid growth worldwide in recent years, Google and Amazon,Apple,Microsoft, optimistic, Yahoo! is mentioned. The management for which every enterprise used IT strategically is being performed.

 The study which applies artificial intelligence and a genetic algorithm to various management issues is being performed at our laboratory. It's various management practice in the production management, the quality control and the enterprise to want to pay attention in particular. Declining birthrate aged society can be supported now with IT and IoT by automating these management practice by AI (Artificial Intelligence) and also automating a manufacturing premise by an industrial robot and automatic control.
 For example, the following image shows the simulation when dealing with the optimal placement problem for an automated robotics warehouse. You can use data science and AI to find the optimal placement based on the big data of the large stock in the past.

 I'm working on the most suitable allocation problem of physical distribution center and a poisonous snake by a genetic algorithm (GA) in the field of the logistics and the supply chain management (SCM). The next figure is the example which solved a optimum arrangement problem of distribution centre in an actual area in GA. The left side is in the state grouped together at random first. That, ton x Kiro(baggage amount x distances) in each business office and physical distribution center repeats alternation of generations in GA, and searches the combination which becomes smallest. And the optimum arrangement result obtained finally starts to be a right figure.

Following results are examples of AI analyzing concrete images and automatically judging the presence or absence of cracks. Work in high and dangerous places can be replaced with automatic work by robots. In addition, AI will be able to automatically judge symptoms that only experts could see. The figure below is examples of concrete images. Normal is a normal image without cracks, and Abnormal is an image with cracks. Also, in parentheses is the result of AI making a decision using a machine learning model called CNN. And the numbers show the percentage of that possibility.

The results below show which part of the image the AI refers to when making decisions. Visualization with GRAD-CAM as technology. The cracked area will be lighter in color. This is the evidence that AI refers to to determine the presence or absence of cracks.

We are researching the use of AI to predict the amount of power generated by solar power generation. In addition to statistical methods, we are conducting research to predict illuminance with AI based on cloud images seen from the ground and information from illuminometers.

The following is the result of automatically taking pictures from the ground using an astronomical camera at regular intervals, excluding the sun, and automatically extracting only the cloud part (colored green in the image) by the program.
