摘　　要：建立了基于随机干扰和部分预支付条件下部分延迟交货的经济订货批量模型。基于部分预支付条件对零售商成本构成进行了详细分析,总成本函数包括固定订货成本、库存持有成本、采购成本、资金成本、变质成本、延期交货成本和损失的销售机会成本。通过理论研究,确定了最优解的存在条件和唯一性。结合运作管理实践,通过数值算例和灵敏度分析,从管理角度提出了决策建议。In this paper,we established the economic order quantity model allowing partially and delayed delivery under random disturbance and partial advance payment.First,we analyzed in detail the retailer’s cost structure in view of the partial prepayment condition,finding its total cost function to include fixed ordering cost,inventory holding cost,purchasing cost,capital cost,deterioration cost,backorder cost and lost sales opportunity cost.Then,through theoretical research,we determined the existence condition and uniqueness of the optimal solution to the function.At the end,in connection with the practice of operation management and through a numerical example and sensitivity analysis,we put forward some decision-making suggestions a managerial point of view.
