HRM 3440 Lecture 8 Notes – LEGO Builds Information Systems from Modular Blocks
Introduction
• Recently, JEA decided to put artificial intelligence to work assisting its wells in pumping
just enough water to meet customer demand.
• It purchased AI-based software from Gensym and created a neural network to predict
hourly consumption of water over a given time frame.
• The neural network is trained using previous water-usage data.
• The consumption forecasts created by the neural net are fed into an expert system.
• The expert system allocates the total anticipated demand to the 44 water treatment
plants and artesian well pumps.
• The schedule for hourly water production is fed into automated systems in the
production and treatment plant to control production and delivery of the water.
• The Gensym software allows JEA engineers to define inputs (including reservoir sensors
and meter-reading) and outputs (such as controls on equipment) to optimize the
production and flow of water through the JEA system.
• It took JEA six months to develop and implement the optimized expert system and
automation.
• The system has resulted in better use of reservoir capacity by filling reservoirs only to
levels required with each hour of operation.
• The needs based production has minimized costs while maximizing water quality.
• Salt intrusion has been reduced, and the health of the wells is increasing.
• As JEA rolls out its new system to all of its wells and treatment plants, it will enjoy
considerable benefits and savings, including lower energy costs and reduced equipment
failures from smarter pumping.
• LEGO blocks are one of the best-known toys in the world.
• Founded in 1932 in Denmark by the Kirk Kristiansen family, which still owns the
company, the LEGO Group has grown to 8,000 employees, providing fun building toys to
children in more than 130 countries.
