Abstract: Considering that the freight cost of unit product is sensitive to lot-sizing, the optimal lot-sizing models both with decentralized decision and integrated decision based on channel partners for different products transportation sponsors were constructed to coordinate the optimal ordering lot-sizing of a purchaser with the optimal manufacturing lot-sizing of a supplier in a supply chain. Study indicated that the more flexible the transportation capacity was, the smaller the optimal manufacturing lot-sizing was, which was in accordance with the short ordering lead time and few lot-sizing that were claimed by the purchaser. Also, it showed that the optimal ordering lot-sizing was closer to the optimal manufacturing lot-sizing when products deliverer was the purchaser, so that it might benefit the whole supply chain since the supplier and the purchaser could obtain a win-win solution.
