“…Defining the equipments optimal set points Increasing the overall system efficiency (Sarimveis et al, 2003), (Arivalgan et al, 2000), (Von Spakovsky et al, 1995), (Frangopoulos et al, 1996), (Puttgen & MacGregor, 1996), (Tstsaronis & Winhold, 1985), (Temir & Bilge, 2004), (Tstsaronis & Pisa, 1994) Several studies on energy monitoring by using physical indicators to analyse energy efficiency developments in the manufacturing industry (especially the energy-intensive manufacturing industry) highlight the close relationship with the concept of specific energy consumption (energy use at the process level) and the international comparability of the resulting energy efficiency indicators as arguments advocating the use of physical indicators in the manufacturing industry (Farla & Blok, 2000), (Worrel at al., 1997). Moreover in (Kannan & Boie, 2003) the authors illustrate the methodology of energy management that was introduced in a German bakery with a clear and consistent path toward introducing energy management.…”
