A hybrid heterogeneous Pythagorean fuzzy group decision modelling for crowdfunding development process pathways of fintech-based clean energy investment projects

Abstract This study aims to evaluate the crowdfunding alternatives regarding new service development process pathways of clean energy investment projects. In this framework, a model has been generated by considering consensus-based group decision-making with incomplete preferences, Pythagorean fuzzy trial and evaluation laboratory (DEMATEL) technique for order preference similarity ideal solution (TOPSIS). Moreover, comparative performed Vise Kriterijumska Optimizacija I. Kompromisno Resenje methodology sensitivity analysis made 4 different cases. The main contribution is identify appropriate crowdfunding-based funding improvement investments novel MCDM model. By iteration analysis, missing parts in evaluations can be completed opposite opinion problems reduced. Furthermore, help hybrid combining DEMATEL TOPSIS, more objective results reached. It concluded that are coherent reliable. findings indicate full launch most significant criterion equity debt-based alternatives. On other side, highest weight reward donation-based whereas design essential item royalty-based alternative. Additionally, it also defined equity-based alternative way, will possible provide continuous resource hand, providing financing equity, there no fixed cost investors. If these investors make profit, they distribute dividends decision their authorized bodies.
