Site Selection of Waste-to-Energy (WtE)‎ Plant considering Public Satisfaction by an Extended VIKOR Method

الملخص EN

Site selection of waste-to-energy (WtE) plant is critically important in the whole life cycle.

Some research has been launched in the WtE plant site selection, but there is still a serious problem called Not In My Back Yard (NIMBY) effect that needs to be solved.

To solve the problem, an improved multigroup VIKOR method is proposed to choose the optimal site and compromised sites.

In the proposed method, the public satisfaction is fully considered where the public is invited as an evaluation group far more than creating general indicators to represent the public acceptance.

First of all, an elaborate criteria system is built to evaluate site options comprehensively and the weights of criteria are identified by Analytic Hierarchy Process (AHP) method.

Then, the interval 2-tuple linguistic information is adopted to assess the ratings for the established criteria.

The interval 2-tuple linguistic ordered weighted averaging (ITL-OWA) operator is utilized to aggregate the opinions of evaluation committee while the opinions of the public are aggregated using weighted average operator.

Finally, a case from south China which shows the computational procedure and the effectiveness of the proposed method is proved.

Last but not least, a sensitivity analysis is conducted by comparing the results with different weights of evaluation group assessments.
