FUZZY CONTROL FOR JAPANESE SAKE — Fuzzy decision controller and fuzzy simulator for Japanese sake fermentation

  • Kaoru Hirota


Japanese sake brewing technology has a history of more than 1,000 years. Many predecessors of the present-day master-hands went through numerous trials to develop the technology, tested their methods and made improvements. These technologies have been based on experience and intuition; until now the master brewer who perfected a technique has passed it on to his successors. However, with the revolution in industrial organization after World War II, there has been a drastic drop in the number of young people who want to work in sake breweries, and aging of the master brewers and technicians has become a problem. The sake industry must resolve this problem if it is to ensure the continuation of sake brewing, one of Japan’s distinctive food industries.
