Abstract:

Micro-combined heat and power (micro-CHP) helps to improve energy efficiency and protect environment, thus becoming a trend in the building energy supply. In the planning stage of a micro-CHP project, evaluation of the design scheme is a key to success. To apply interval data criteria of the scheme to technique for order preference by similarity to an ideal solution (TOPSIS), the distance range and relative closeness are calculated using the interval ideal solution. An acceptability function is defined to in sort schemes. An example of 4 alternatives suitable for small buildings is presented to show feasibility and practicability of the method.

Key words: interval data, multi-criteria decision, technique for order preference by similarity to an ideal solution (TOPSIS), micro-combined heat and power (micro-CHP)
