To reduce the safety stock levels and the fee in purchase and sale process, entities in supply chain use long-term agreements instead of short-term agreements. Due to the uncertainties of order release time, quantity of demands and delivery lead times, the stock risk comes to be one of the major risks of the supply chain. This paper describes a method to reduce the stock risk using time-bargain in trade process of supply chain. Under the net model of supply chain, entities use unratified orders instead of common orders. When the up-level entities deal with the un-ratified orders, the un-ratified orders can be exchanged among the down-level entities using time-bargain, and can be also modified between up-level entities and down-level entities using order modification rules. In a unit period, entities obtain the ratified orders by recombining the unratified orders, thus to reduce the stock level of entities in the supply chain. To reduce the demand risk, down-level entities can purchase, sale, modify or reject un-ratified orders. With the recombined ratified orders, up-level entities can reduce the demand arrival time risks and demand quantity risks. In this way, the cooperation among the supply chain entities would be smoothen and durative.
