摘要: Abstract The provision of adequate and reliable supply utilities (fuel, steam power) represents a significant operating cost for many industrial companies. Refinery, petrochemical utility companies can address the key issues associated with purchase, usage such within environmental constraints through use single Energy Management tool to optimise energy business processes substantially improve financial performance (typically equivalent 2 5% total costs). For industries, energy/Utilities is largest expense after purchase raw materials. Many large are focusing on reducing costs energy, deregulation market in both USA Europe has made “intelligent” purchasing Utilities very important. Industrial have used various tools an attempt monitor energy; these include spreadsheets, monitoring targeting, simulation expert systems. To-date, most do not that allows economic integration all .
