Abstract: Since the uncertainty of the shortage cost in new Newsboy products inventory control, this paper analyzes the influence of the shortage cost on the retailers’ optimal order, and unit shortage cost being as trapezoid fuzzy number, constructs a new Newsboy products inventory control model based on the fuzzy shortage cost, solves the model by using fuzzy algorithm. Results show that when the unit shortage cost cannot be accurately estimate, it is not only feasible, but also effective that the uncertainty of unit shortage cost is scaled by fuzzy unit shortage cost in order to draw an order interval, and the numerical analysis proves this point well.

Key words: fuzzy shortage cost, new Newsboy products, inventory control, optimization

摘要: 鉴于新Newsboy型产品库存控制中缺货成本的不确定性,考察了缺货成本对零售商最优订购量的影响,将单位缺货成本视为梯形模糊数,构建了一个基于模糊缺货成本的新Newsboy型产品库存控制优化模型,并运用模糊运算法则对该模型进行了求解。结果表明,当单位缺货成本不能准确估计时,采用模糊单位缺货成本对单位缺货成本的不确定性进行刻画以得出一个订购区间,不仅是可行的,而且也是有效的,最后的数值分析很好地证明了这一点。
