Abstract
: The purpose of the study is to evaluate the sustainable energy investments based on house of quality. For that, a hybrid decision-making approach to interval type 2 (IT2) fuzzy sets under the hesitancy is proposed. The novelties of the study are to construct an integrated IT2-based modelling and a set of dimensions and criteria for the sustainable energy investments for the emerging countries. The DEMATEL method is used for weighting the customer expectations of sustainable energy investments. The TOPSIS method is applied for ranking the house-of-quality-based investment policies with the technical requirements for the emerging economies. The results show that the capacity issue of energy industry is the most prominent issue for the technical requirements of energy investments. However, it is concluded that increasing communication with the capacity facilities is the most valuable strategy based on the house of quality evaluation. The results are also discussed for further studies and sustainable policies.
Highlights
Selecting sustainable investment policies has a key role in effective business strategies
This study contributes to the literature by using the integrated method of DEMATEL and TOPSIS based on interval type-2 fuzzy sets
A hybrid decision-making approach is proposed for ranking the sustainable energy investments of emerging economies with the house of quality and the type 2 fuzzy sets-based model is applied for evaluating the criteria and alternatives more accurately
Summary
Selecting sustainable investment policies has a key role in effective business strategies. Sustainable investment policies in the energy industry should be considered in a multidimensional manner by considering customer expectations and technical requirements at the same time. Investment evaluation in emerging economies highly needs both financial and non-financial conditions of a dynamic market for successful business planning. The multidimensional approach to energy investment policies brings valuable results for the project’s success and the quality improvement with both customer needs and technical requirements is the best way to use the target market and research and development facilities. Customer needs and technical requirements are evaluated for the sustainable energy policies of emerging economies. To the interval type 2 fuzzy sets with the linguistic terms under the hesitancy, a hybrid decision-making approach for the sustainable energy investments in emerging economies is applied. The final section highlights the discussions and conclusions for further researches
