中文摘要：

假定装备制造商具有批发决策权，生产率是市场需求率的线性函数，市场需求率是价格和营销成本的函数。在考虑需求函数和运输成本函数的基础上，建立装备制造商的批发价和订货批量决策模型，并对模型的性质进行分析。研究表明：制造商的最优批发价与生产启动成本、生产成本、固定运输成本和单位商品库存成本成正比；与制造商生产率和订货批量成反比。制造商最优订货批量与市场需求率、固定运输成本、生产启动成本和制造商生产率成正比，与零售价和单位库存成本成反比。

英文摘要：

Assuming that heavy equipment manufacturer has the power of order quantity decision-making, that productivity rate is a linear function of market demand, and that market demand rate is a function of price and marketing costs. Based on demand function and the transport cost function, heavy equipment manufacturer＇ s wholesale price was made and order quantity decision model was built, and properties of the model was analyzed in this paper. The study shows that production start-up costs,production costs, fixed transportation costs and unit inventory costs have positive impact on manufacturer＇ s optimal wholesale price, while productivity have negative impact. Market demand rate, fixed transportation costs, production start-up costs and productivity of manufacturers have positive impact on manufacturer＇ s optimal order quantity, while retail price and unit inventory costs have negative impact.
