with a focus on making more advanced use of the manufacturing know-how and data accumulated todate. The objectives are as follows:
Reconstruction of in-house infrastructure utilizing information coordination and big data on
manufacturing, quality, the environment, etc.
Analysis of data collected on manufacturing, quality, the environment, etc., and construction ofanalysis methods
Improved productivity as a result of reduced downtime due to stoppage of manufacturing facilities
and reduction of out rate
Organizing information on manufacturing support with a focus on the interests of manufacturing
staffSaTeras is a system that can solve problems such as the depersonalization of human resources inmanufacturing and a super-aging society. It uses the production data that has been cultivated up to
now and transforms it into formal knowledge by structuring the tacit knowledge. SaTeras provides anenvironment in which in which anyone can access and use the data to improve their manufacturing
process. It also enables high-level coordination of information. Because it is possible to combinefunctions and services, the design of SaTeras is flexible even in request to increased processing
capacity.
