Abstract: To make the supply chain satisfy customers' demand under stochastic supply disruptions,an emergency robust strategy of the supply chain was researched.Under the stochastic supply disruptions,an emergency fuzzy model of the supply chain with multiple lead times was constructed based on Takagi-Sugeno fuzzy control system.According to the different inventory statuses of each member for different periods,the manufacturer's production strategy and the distributors' emergency ordering strategies were designed.Then a fuzzy robust control strategy was proposed to restrain the impacts of lead times and uncertain demand on the emergency supply chain.The emergency robust strategy comprised of the emergency ordering strategies and the fuzzy robust control strategy could realize the robust stability operation of the supply chain emergency system with low cost.A simulation example was given to show the feasibility and effectiveness of the emergency robust strategy of supply chain.

Key words: supply chains, emergency strategy, supply disruption, lead time, robust control
