通过引入期权合约,研究在产品市场需求不确定条件下供应商管理库存(VMI)供应链的协调。研究表明,首先,在VMI供应链协调中,市场不确定程度越高,期权合约越重要,供应商销售或者零售商订购的期权越多;其次,对整个VMI供应链而言,期权合约使得供应商获得更大比例的利润;最后,零售商订购期权更多是出于规避缺货风险的动机,而非单纯地增加利润。 By introducing the option contract, this paper studies the coordination of supplier managed inventory (VMI) supply chain under the uncertainty of product market demand. The research shows that firstly, in the coordination of VMI supply chain, the higher the degree of market uncertainty, the more important the option contract is, the more options the supplier sells or the retailer orders; secondly, for the entire VMI supply chain, the option contract makes the supply Get a larger percentage of profits. Finally, retailers place more of their options on motivation to avoid the risk of out of stock, rather than simply increase profits.
