In this paper a detailed CUSUM quality control chart
for monitoring energy use performance is given. This
method can also be easily applied for monitoring the fuel
consumption in a similar manner.
This paper discussed the problem based on electrical
energy consumption in melting furnaces of foundry
industry. Drawing on the existing theory and based on the
problem selected, it is found that CUSUM charts are
valuable for monitoring energy use process, as they tend
to detect process shifts on the 14 th day itself than
traditional charts showed no change. This will lead the
decision maker to proactively respond to the out put
control situation and correct the problems well in time.
