在提前期可控、订购成本可减的情况下,研究了有顾客流失的单买方和单卖方联合期望总成本最小化问题。将订购批量、单位订购成本、安全系数、提前期和运送批次作为决策变量,在提前期需求服从正态分布和分布形式未知的情况下各建立了一套库存决策模型和求解算法,并与Liao等模型的求解结果进行了比较。
The minimum problem of the single-vendor single-buyer’s total expected cost involving controllable lead time,ordering cost reduction and lost sale was considered. By taking order quantity,ordering cost,safety factor,lead time and number of lots as decisional variants,the paper presented a set of inventory decision models and algorithms in the normal distribution demand and the distribution-free cases respectively and compared its solutions with Ouyang et al (2004) inventory models with a numerical example.
