基于顾客具有时间与价格敏感性和服务价格是服务承诺时间的分段函数前提假设下,建立了相应的服务承诺时间决策模型,并证明了最优服务承诺时间L*的存在性,分析了相关参数对L*的影响.研究发现:当L*小于行业水平L0时,低成本服务商应声明较短的服务承诺时间;随着顾客时间敏感系数的减小或顾客之间保留支付差异的增大,服务商应延长服务承诺时间.当L*>L0时,服务商应声明较长的服务承诺时间;随着顾客价格敏感系数的增大或顾客平均保留支付的减小,服务商应延长服务承诺时间,并降低价格.
Based on the assumption that customers have time and price sensitivity and service price is a piecewise function of service commitment time, a corresponding decision model of service commitment time is established and the existence of optimal service commitment time L * is proved. The correlation The effect of parameter on L * The study found that: when L * is less than the industry level L0, low-cost service providers should declare a shorter service commitment time; as the customer time-sensitive coefficient decreases or customers pay the difference between the increase Service providers should extend the service commitment time.When L *> L0, service providers should declare a longer service commitment time; service providers should be extended as the customer price sensitivity coefficient increases or the average customer retention payment decreases Service commitment time, and lower prices.
