Site selection decision of waste-to-energy projects based on an extended cloud-TODIM method from the perspective of low-carbon

The waste-to-energy (WTE) project has become a vital part for the development of renewable energy for its characteristic of harmlessness and resource utilization, and the concept of low-carbon has gradually become the universal consensus of all countries. How to select a satisfactory site for WTE project to make a win-win situation under a low-carbon perspective has become the concern of many researchers. Deficiencies in the current site selection process may lead to inaccurate results. To solve such problems, this paper proposes an extended cloud-TODIM (Tomada de Decisao Iterativa Multicriterio) method. Firstly, we construct a criteria system covering five criteria and eighteen sub-criteria. Secondly, the evaluation information is described through the hesitant fuzzy linguistic term set (HFLTS) with credibility and then the hesitant fuzzy linguistic term set is converted to clouds, which can fully describe the fuzziness, uncertainty and randomness. Thirdly, the weights of criteria are calculated by the combination weight of Analytic Network Process (ANP) method and entropy method. Furthermore, an improved TODIM method is proposed to select the optional alternative. Finally, a case in Shaanxi province is provided to verify the feasibility of our method. (C) 2021 Elsevier Ltd.
