The comprehensive evaluation of renewable energy system schemes in tourist resorts based on VIKOR method

摘要

The selection of the renewable energy system schemes in tourist resorts is a multi-criteria decision problem. This paper firstly establishes an evaluation criteria system which comprises three main criteria and nine sub-criteria for the renewable energy system. Then Vlsekriterijumska Optimizacija I Kompro-misno Resenje (VIKOR) method is adopted to rank the renewable energy system schemes. Finally, six renewable energy system schemes in a tourist resort are selected to demonstrate the proposed method. The results indicate that the weight of economy, technology and environment are 0.6, 0.2 and 0.2 respectively. And the general weights of the sub-criteria are: 0.348 (B_(11)), 0.186 (B_(12)), 0.066 (B_(13)), 0.086 (B_(21)), 0.086 (B_(22)), 0.028 (B_(23)), 0.04 (B_(31)), 0.12 (B_(32)) and 0.04 (B_(33)). The general weight of the investment cost and the annual operation cost accounts for a relatively large proportion, which is 34.8% and 18.6% respectively. The ranking order of the six schemes based on Q_j, S_j, and R_j are Q_2＞Q_6＞Q_5＞Q_4＞Q_3＞Q_1. S_2＞S_6＞S_4＞S_5＞S_1＞S_3 and R_6＞R_2＞R_5＞R_3＞R_4＞R_1 respectively. After a compromise, the final ranking results are: Scheme 2, Scheme 6 ＞ Scheme 5, Scheme 4 ＞ Scheme 3, Scheme 1. This study can provide guidance for the decision makers to determine the renewable energy system scheme in tourist resorts.
