在产能固定的情况下,考虑两类客户no show的随机性,建立了两类客户no show情况下易逝品的超售决策模型,
得到了订货量的最优解.算例分析结果表明:普通客户单位订货价格对最优订货量有显著影响,而VIP客户的单位订货价格只
有超过一定值时,才能显著影响最优订货量;两类客户的单位补偿对最优订货量的影响都较小;两类客户的短缺成本对最优订
货量均有明显影响,相比而言,普通客户的短缺成本对最优订货量的影响更大.

By considering both the random of customer's no show and constrain of capacity, we establish the overbooking model of perishable products based on two kinds of customer's no show, and the optimal solution is obtained.   Numerical example shows that the unit price of usual customer has an important impact on the manufacturer's  optimal overbooking, while the unit price of VIP customer could impact manufacturers' only  when the price goes beyond a certain value.   And numerical example also shows that two kinds of customer's unit compensation have little impact on the    manufacturer's optimal overbooking. Finally, the shortage costs of capacity for two kinds of customers had an  obvious influence on the manufacturer's optimal overbooking. Comparing with the unit shortage cost of VIP customer,  the unit shortage cost of usual customer had a greater impact on the manufacturer's optimal overbooking.
