简介：由于围住的合理性，如果决定包含立即的报酬，人们经常为即时满足冲，但是如果决定包含立即的费用，拖延。当人们正在做内部时间的决定以后做贸易离开报酬和费用时，偏导礼品的偏爱和时间矛盾愿望是更突出的。人们超过礼品，他们为在未来的结果的偏爱将随着时间的过去衰退。在伪夸张的打折下面合并偏导礼品的偏爱和时间矛盾，完全与缺乏在通货膨胀和变化时间的需求下面预定钱的价值backlogged，我们为一个败坏的项目开发一个库存补充模型。有益于决定制造者的库存补充政策如下。随时间矛盾的增加，一个人能增加订缺乏的数字和减少部分；随在上面的限制以内的危险率的增加，一个人能增加订缺乏的数字和减少部分；随加重的贴现率的增加，一个人能增加订缺乏的数字和部分。夸张打折增加订的数字并且减少夸张打折的最后的利润，和度加强如此的结果。作为结果，当做内部时间的决定时，为一个决定制造者的最佳的政策是保持尽可能合理。
