This paper proposes a hybrid solution algorithm for the mixed-integer bi-level programming problem (MIBLP) as a mathematical model of the Stackelberg game with the novelty inclusion of multi-followers in competition. The solution strategy considers the MIBLP as a multi-parametric problem knowing that the feasible set of the lower level problem (LLP) of a bi-level programming problem (BLPP) is parametric in terms of the optimization variables of the upper level problem (ULP), under those circumstances is possible to solve each level with a different approach. To tackle the oligopoly (multi-player) competition in the LLP, a general static Cournot equilibrium model is proposed, with the particularities of non-differentiated product with asymmetric cost. The proposed hybrid algorithm implements Differential Evolution to solve the ULP while each feasible population member of each generation execute a MILP Solver to search for feasible LLP individuals sharing the market and looking to maximize their individual profit. The algorithm, which is a new method for the resolution of MIBLP, is illustrated through a modified numerical example from the literature adapted to Energy Markets. Competitive energy markets are the best way to keep prices as low as possible and create a climate that encourages economic growth, job creation and innovation. Demand and supply of energy are best determined through fair and competitive markets, meaning, well-designed competititve markets deliver better results than traditional monopoly markets. Until now, most of the Hydrogen Supply Chains (HSC) designs are treated as problems with single or multiple objectives without any hierarchical conflict, mainly in a centralized monopolic view point. Computational results prove the functionality of the proposed hybrid algoreithm on a ficticious HSC, the evidence highlights the impact between choosing a monopoly or an oligopoly production model. |
