“…A number of authors have used numerical or algorithmic approaches to solve for the Nash equilibrium (Razi, Shahri, & Kian, 2007;Konak, Kulturel-Konak, & Snyder, 2015;Wang, 2013). Zhang & Zhou (2012) have built supply chain network equilibrium models as nonlinear problem formulations (Zhao & Nagurney, 2008); they employed smooth Newton algorithm (Ma, 2011) for solving the non-linear games but struggled to prove the existence and uniqueness of the equilibrium. A three stage game theoretic linear and un-constrained supply chain model is built by Xiao, Jin, Chen, Shi, & Xie (2010) employed traditional analytical approach and carried out complex calculations to examine existence of Nash equilibrium.…”
