| Summary: | 碩士 === 國立成功大學 === 工學院工程管理碩士在職專班 === 101 === Energy saving and CO2 emission reduction have become a mainstream of energy-saving issue so far. Over the past several decades, the electricity price in Taiwan was quite cheap. Besides, high-technology industry belongs to one of the industries with lower energy intensity, so the cost of energy consumption makes up a small percentage of the whole manufacturing cost. As a result, both of which indirectly cause the fact that most of the high-technology factories don't attach importance to energy saving. In June 2012, Ministry of Economic Affairs proclaimed a scheme of rationalizing electricity prices, in which the government increased 35% of industrial use of electricity and 50% of high-voltage electricity in summer. It is afraid that the scheme would strike the gross profit of high-technology industries.
Energy efficiency perspective covers a wide range such as electricity, lighting, compressed air energy savings, green buildings, or even substitute like wind power and solar photovoltaic energy etc.. Factories have even more plans to save energy. Under the condition of limited resources, how to comprehensively lower demand for electricity and rationalize electric power consumption became the issue for investigation of the research.
The research takes Company M as an example to study and the purpose is to construct the energy-saving under AHP selecting mode of high-technology factories and to confirm evaluating value weighting of every energy-saving program, which is a basis of implement priorities. First, the research will establish the energy-saving mode of high-technology industries by document analysis and interviewing with practice experts. Second, after the rated value of energy-saving programs from the first step, the research will seek relative weights of assessment criteria by interviewing with practice experts. Both of the above enable the factories to own an organized and doable energy-saving plan to lower cost of production, meet environmental requirements and upgrade competitive strength of high-technology industries.
The result came out of five assessment criteria of the energy-saving under AHP selecting mode of high-technology factories, which are “investment cost on facilities”, “energy-saving benefits”, “impacts on production surface”, “comfort of working environment” and “effects of energy-saving and carbon-reduction.” In addition, five classifications of energy-saving program, “energy-saving by operation”, “energy-saving by control”, “energy-saving by facilities renewing”, “energy-saving by system integration” and “energy-saving by energy monitoring” plus 24 energy-saving plans are synthesized.
The relative weights are ordered from 0.389 on “investment cost on facilities”, 0.275 on “energy-saving benefits”, 0.215 on “impacts on production surface”, 0.081 on “comfort of working environment” to 0.040 on “effects of energy-saving and carbon-reduction.” We sort the evaluating value weighting of the five classification of energy-saving program, and carry out in three stages going with practical limitation. There are 8 plans each in three stages which can be reference for high-technology factories in Taiwan.
