Summary:博士 === 國立政治大學 === 資訊管理研究所 === 93 === Supply chain management is a complicated task because of uncertainties involved. The uncertainty that occurs in the processes of inter-organizational coordination is due to a lack of harmony in supply chain participant activities. Recent developments in Inter-organizational Systems (IOS) have contributed to the provision of IT-based solutions for harmonizing supply chain participant activities. Applying IOS to the supply chain often attempts to improve the efficiency of coordination and resource integration among participants via inter-organizational information sharing. This intention implies that the effectiveness of IOS depends on whether information sharing mechanism built into the system can fit for supply chain characteristics and can help the supply chain cope with uncertainties that disrupt the integration of the supply chain. Hence, establishing an environment-suited information sharing mechanism is critical in deploying IOS solutions, and diagnosing supply chain uncertainties is important in planning information sharing mechanism. Diagnosing supply chain uncertainties is a complex and challenging task, it needs a structural framework to support in analyzing the intricacy of interactions among supply chain members, resulting in the construction of an instrument to assist in the understanding of uncertainty-related behaviors of supply chain participants. Therefore, this study takes a structural approach to produce a validated uncertainty scale, and applies a case study approach with this instrument to investigate the uncertainty problems in a specific supply chain type, convergent assembly supply chain. After understanding the uncertainty problems, this study proposed a reference model to assist this supply chain type in planning an information sharing mechanism, leading to a well-suited IT framework to improve supply chain integration. Falling short of a sounding information sharing mechanism is central to the problems in convergent assembly supply chain based upon the findings of case studies. The incompatibility between supply chain environment and existing information sharing practices has led to the problems in demand variation and material supply. Based on the characteristics of supply chain environment, planning inter-organizational coordination and information sharing simultaneously can effectively resolve the supply chain problems. Moreover, the research results suggested that the pattern of information sharing is influenced by the scale and severity of the uncertainty embedded in supply chain. In the case of convergent assembly supply chain, information sharing is focused on issues related to material supply owing to the structural characteristics of supply chain. The combination of participants in supply side is more complex and is not familiar with the leading company as demand side’s participants. Therefore, it needs to pay more attention for establishing information sharing among supply side’s participants.
