Abstract How to prompt the supply chain system to resume its normal operation quickly and effectively after the disturbance of the emergency has become a problem to be solved. This article takes short life cycle products as the research object, considering the existence of B2B electronics market, and introduces bidirectional option contract. Through model construction and numerical analysis, the optimal decision of supply chain members under emergencies is studied. The change of contract parameters and the influence of market demand fluctuation on the optimal expectation profit of member enterprises are examined. The results show that the combination of two option and B2B electronic market can effectively cope with the fluctuation of demand caused by unexpected events.
