The suitable energy alternatives scheme

which for.mulated based on the optimal target of technical and economic com.prehensive indicators

is significant to achieve energy saving

emis.sion reduction and comprehensive energy utilization.In the energyalternatives scheme

the fuzzy multi.attribute decision.making meth.od based on the expectation value is proposed in the situation thatthe weight information is completely unknown or only partiallyknown; and a preferred evaluation index system is constructed

toquantitative analysis the attribute values of the evaluation index.The weighting method of complementary comparison between eachother is used to determine the weight of each layer in the index sys.tem

so as to realize the quantitative comparison and the optimizedselection of energy alternative schemes.Based on the case study

itis verified that the energy alternative evaluation method based onfuzzy multi.attribute decision.making is highly efficient

practicaland easy to operate

at the same time

it can make full use of thefuzzy information which is objectively known and take into accountthe interests of all parties.
