缺货成本与时间无关的经济批量订货模型

Economic ordering quantity model of shortage cost irrelative to time

应用数学建模方法建立了在缺货要补充、缺货成本与时间无关的情况下,瞬时供货和匀速供货的经济批量订货模型,推导出了最优订货周期和最优订货量等一系列相关公式,然后以实例说明了它的使用方法,并利用计算机进行了仿真,仿真结果与理论结果基本相符,从而验证了建模假设的合理性。

By establishing economic ordering quantity model of instantaneous and uniform speed supplies under the circumstances of supplementing at the time of shortage and shortage cost irrelative to time, it infers a series of relative formula, such as the excellent ordering period, the excellent ordering quantity, and so on. It illustrates by examples its usage and simulates by computers. The simulation result is almost in agreement with theoretical result. Therefore, it verifies reasonableness of hypothesis of constructing models.
