考虑订单合批批量的在线制造商承诺交货期决策研究

摘要

承诺交货期策略即向所有顾客承诺一致的交货时间是在线制造商最常用的基于时间的竞争策略。制造商通过调整运营参数来改变交货时间以实现向顾客承诺的交货期。基于运营批量对生产提前期的影响，本文构建了考虑订单合批批量的承诺交货期决策模型，分析了各种参数对生产提前期与运输提前期决策的影响。研究表明，库存成本、单位产品的加工时间、顾客需求的价格敏感性和时间敏感性系数等参数对于在线制造商的生产提前期和运输提前期决策往往具有不同的影响。最后本文的算例验证了研究的结论。%For make-to-order ( MTO) on-line manufacturers , one of the most popular time-based competi-tive strategies is to widely advertise a uniform delivery time “guarantee” to all the customers .While provi-ding time guarantee can be an effective marketing approach , it is critical for firms to reduce lead time to keep the promise .Decreasing lot size in batching is one of the most important levers to compress lead time in operations.An online manufacturers ’ guaranteed delivery time model with order batching is estab-lished.The effects of batch processing setup cost , unit inventory holding cost , and unit compression cost of transportation time are analyzed .Some analytic results are provided , and numerical examples are conduc-ted to provide further insight into the problem .The results indicate that when batch processing setup cost , unit inventory holding cost , or unit compression cost of transportation time increase , the online manufactur-er should decrease the lot size and shorten the guaranteed delivery time .
