A typical blood bank gets its major supply of blood from organizing blood donation camps. The quantity of blood collected in the blood donation drives is random and it might be sensible to cut off the supply at some level to reduce the wastages by overcollection.
In this paper we introduce two new cutoff level policies and compare their performance with the policy of collecting all the available supply at blood collection drives, which is quite prevalent among the blood banks. We develop a simulation model for collection that enables such comparison on the basis of shortages, wastages, and total costs.
The results obtained from the simulation model for a real-life situation show that the cutoff level policies are better than the unrestricted collection policy in controlling total costs. They also result in less wastage in the system for a given level of shortages.
一个典型的血库主要通过组织献血活动来获取血液供应。在献血活动中采集的血量是随机的,因此在某种程度上切断供应以减少因过度采集造成的浪费是明智的。
在本文中,我们介绍了两种新的截止水平政策,并将其性能与在血库中相当普遍的在献血活动中收集所有可用供应的政策进行了比较。我们开发了一种采集模拟模型,以便能够根据短缺、浪费和总成本对这些政策进行比较。
对实际情况的模拟模型的结果表明,截止水平政策在控制总成本方面优于无限制的采集政策。对于给定的短缺水平,它们还能减少系统中的浪费。
