My consulting company uses an MCI based model. Now a friend sends me this article (https://www.sciencedirect.com/science/article/pii/S0921344925005592). The employee that developed the models for our company (Circularity specialist) not longer works for use so we can't really evaluate what this means for our models. Is this a real journal? Shall I get my models re-checked or is this just academic noise/junk?
