Bulter, Ammons, and Sokol argue that the model of new product supply chain of the past neglects the condition which new products may not survive. Thus they developed a new product supply chain model to enable new products to launch the market and grow to maturity as well as decide when to purchase new supply chain facilities and equipments.
学者Butler, Ammons, and Sokol认为过去新产品供应链模式忽略了新产品将有可能无法存活下来的情形,因此发展一套新产品供应链模式,使新产品供应链能够顺利从上市成长到成熟阶段,并利用此模式决定新设施、新机器购入的时机。
