In this paper, we formulate a competitive version of the traditional aggregate production planning model with capacity constraints. We utilize a successive Bertrand–Cournot framework in which the raw material supplier sets the price (i.e. the Bertrand model) and the producer then sets the production quantity (i.e. the Cournot model).
