摘要: | 疫苗为高单价产品,对温度敏感且具时效性,一旦发生温度改变或是其他原因,造成疫苗变质、毁损等情况,可能造成疫苗功能失效,更可能因而产生庞大的成本损失。近年来有许多针对低温物流配送问题之研究,然而这些研究大部分针对食品、花卉、农产品(蔬菜、水果)等物品进行研究,鲜少针对低温疫苗配送问题进行探讨。 有鉴于此,本研究针对低温疫苗配送流程进行企业流程再造(Business Process Reengineering, BPR)文件化方式,运用失效模式与效应分析手法(Failure mode and effects analysis, FMEA)及无线射频识别(Radio Frequency Identification, RFID)技术开发一套监控疫苗配送流程之资讯系统,建立一套标准化疫苗配送程序与紧急警报功能,以避免疫苗发生失效之情况,并将此套RFID资讯系统于实务上进行测试与应用。 本研究之结果显示RFID资讯系统的建立确实有其必要性,透过即时性监控温湿度功能,使用者可以随时掌握疫苗温湿度之现况,相对于现行疫苗配送流程,于配送过程中发生任何情况无法得知,若不幸疫苗温湿度发生异常,通常仅能于事后察觉。因此,建立一套温湿度监控机制,符合事前防范优于事后察觉之理念,且警报功能之设计可提早警报使用者疫苗将可能进入异常状态,使用者可提前进行紧急处理,避免疫苗发生失效情况,其节省之成本具有相当效益。 从社会安全的角色来看,RFID资讯系统的建立,可有效掌握疫苗于配送流程中的即时的温湿度变化,相较于现行疫苗配送流程缺乏通透度之情况,可避免因惧怕庞大的赔偿成本于隐瞒疫苗失效事实,进而增加使用者在使用疫苗时之可靠性与安全性。 Vaccines are high-value products with higher sensitivity in temperature control than other products. When the temperature readings of vaccines fall in out of-control range, the batch of vaccines may be damaged, and it usually leads to a huge loss. Many researchers have been working on the studies of logistics for “cold-chain”, e.g., food, flowers, agriculture products such as vegetables and fruits, etc. recently. However, few studies addressed to the temperature monitoring in the distribution of vaccines in the literature. In order to solve this problem, we employ the techniques of Business Process Reengineering (BPR) and Failure Mode and Effects Analysis (FMEA) and the Radio Frequency Identification (RFID) technology to propose a Standard Operating Procedure and develop an information system for monitoring the distribution processes of vaccines in this study. Our results show that the proposed RFID-based information system is very helpful for the distribution processes of vaccines since it monitors the temperature readings in a real-time fashion that significantly improves the as-is situations in which the users can not detect the occurrence of any incident/failure until the distribution process of vaccine has been out of control. Therefore, our proposed system also highlights its alerting function that is able to show warnings and to allow the users some time for taking actions in advance. We assert that our proposed system is able to save considerable costs by avoiding the occurrence of the failure of vaccines. With the view of social warfare, the proposed RFID information system can assist the users to monitor the temperature readings so as to avoid the concealment of damaged vaccine and to effectively improve the reliability of the distribution processes and to security the quality of vaccines. |
