考虑由1个供应商和两个零售商组成的短生命周期产品两级供应链系统,两个零售商面临的市场需求相互独立且零售商发生缺货时允许产品相互转运.建立了无市场需求满足率约束和有市场需求满足率约束两种情形下,零售商之间采用不转运策略和应急转运策略的订货量决策模型,并求出各类模型的最优解和最优值,然后从理论上证明了两种策略的优劣,得出:无论存在市场需求满足率约束与否,当单位产品转运费用不高于特定的临界值时,应急转运策略下的零售商订货量和期望总费用均不高于不转运策略下的订货量和期望总费用.最后通过算例分析,验证了应急转运策略的效果,并分析市场需求满足率和单位产品转运费用对转运策略的影响,得出一些具有参考价值的管理结论.
Considering a short-life-cycle product supply chain consisting of one supplier and two retailers, inwhich the demand faced by the two retailers is independent and product transshipment between the two retail-ers is allowed. The ordering decision models with transshipment and without transshipment between the retail-ers, as well as with the market satisfaction rate constraint and without market satisfaction rate constraint aredeveloped, respectively. The solutions for transshipment policy and non-transshipment policy are derived ac-cordingly. It can be shown that, whether the market satisfaction rate constraint is considered or not, if unitproduct transshipment cost is not greater than a specific value, the retailers' order quantity and expected totalcost resulted from the transshipment policy is not greater than that from non-transshipment policy. At last, anumerical example is given to demonstrate the effect of emergency transshipment policy and analyze the impactof market satisfaction rate and unit transshipment cost on the transshipment policy. Some helpful managerialinsights are drawn.
