Abstract:

In order to reduce the inventory, the presale strategy was introduced into dual-channel supply chain network of fashionable apparel. The demand function in presale stage was designed and the influence on demand in normal sale stage of demand in presale stage under the strategy was analyzed. Then the mixed integer programming model of dual-channel supply chain network which contains the manufacturers, distributors and retailers was proposed based on production cost, transportation cost, storage cost, advertisement cost and so on, and solved with Lingo 11.0. Finally, through the example simulation, it was verified that the presale strategy has favorable effect on demand prediction in normal sale stage and can effectively reduce the inventory cost and shortage loss. By making further sensitivity analysis to the free rider coefficient based on the numerical simulation, the results show that the overall revenue of supply chain continuously decreases as the free rider coefficient increases.
