Supply chain option contract coordination with e-market based on hybrid intelligent algorithm

In the environment of e-market, based on the Stackelberg game, the stochastic expectation model of supply chain option contract coordination with random demand, random market price and market access degree is established in this paper. As the leader, the supplier declares the optimal contract reservation costs and execution costs for maximizing his expected profit, while as the follower, the purchaser responds with the optimal orders for maximizing his expected profit. The given Stackelberg model is solved by the hybrid intelligent algorithm, including Monte-Carlo simulation, artificial neural network, and genetic algorithm. Finally, combining with the e-commerce practice of Shanghai Baosteel Yichang Company, the simulation analysis is carried out, and the optimal order quantity, contract reservation costs and execution costs of supply chain option contract coordination are worked out through the hybrid intelligent algorithm.
