产能和生产机制对供应商和采购商供应链的决策和绩效有重要影响。本文考察了产能扩张投资和供应商的订单式供应链(MTO机制)或订货式供应链(MTS机制)对供应链均衡决策和绩效的影响。对于每个供应商的生产机制,我们推导出相应的均衡批发价、订货量和产能。结果表明,当供应商有足够的现有产能或产能投资成本较小时,MTS机制下供应链的最优产能投资和总利润总是高于MTO机制下的最优产能投资和总利润。相比之下,MTS机制可能导致产能低下,获得的总利润低于MTO机制。计算实验表明,在需求不确定性较低的场景下,MTO机制优于MTS机制;反之,MTS机制优于MTO机制。当产能成本相对较小时,MTS机制下的供应链效率总是高于MTO机制下的供应链效率。
Capacity, and production mechanisms significantly affect the decisions and performance of supply chain with a supplier and a buyer. This study examines the influence of capacity expansion investment and supplier's make-to-order supply chain (MTO mechanism) or make-to-stock supply chain (MTS mechanism) on the equilibrium decisions and performance of supply chains. For each supplier's production mechanism, we derive the corresponding equilibrium wholesale price, order quantity, and capacities. We show that, when a supplier has sufficient existing capacity or the cost of capacity investment is small, the optimal capacity investment and total profit of a supply chain under MTS mechanism are always higher than that under MTO mechanism. By contrast, a MTS mechanism may induce low capacity and gain total profits lower than that of MTO mechanism. Our computational experiment shows that MTO mechanism outperforms MTS in scenarios with low uncertainty of demands; otherwise, MTS mechanism outperforms MTO mechanism. And if the cost of capacity is relatively small, the supply chain efficiency under MTS mechanism is always higher than that under MTO mechanism.
