The profit stability of supply chains with combined contracts under demand uncertainity

This paper considered the effects of the vertical and horizontal competition between supply chains, constructed two three-level supply chains based on buy-back combined contracts and revenue-sharing combined contracts through multi-agent simulation. We analyzed the impact of demand uncertainty on the profit stability of the relevant members coordinated with different types of combined contracts. Simulation results indicate that the combined contracts have no significant impact on the earnings stability of the supply chain, but different coordination mechanisms have different effects on the stability of member´s profit.
