博士 === 國立交通大學 === 工業工程與管理系所 === 103 === Cold chain management is of importance for manufacturers in the food industry since they face the dilemma of having to choose between frozen storage and cool storage in delivering products to retailers or end-consumers. Frozen storage incurs high-energy consumption for the preservation of food products, whereas cool storage involves the constant threat of bacterial decay. Contemporary cold chain development in temperature control tends to focus on single logistic chain rather than serving multiple channels. In order to overcome the aforementioned deficiency, this study proposes an innovative cold chain time-temperature indicator (TTI) system, which uses wireless sensors for the collection of temperature data and implements the formulation of Critical Control Point (CCP) criteria throughout the entire delivery process. Basically, this approach is based on an Internet-of-Things (IoT) architecture as well as international food standards named ISO 22,000. In particular, the proposed IoT solution embedded service design thinking was applied to a prestigious food franchise in Taiwan to help this company switch a number of products from frozen storage to cool storage. The proposed framework expected can efficiently increase product sales, distribution channels, and effectively reduce energy consumption.
