博士 === 國立臺灣大學 === 資訊管理學研究所 === 101 === The development and application of information systems are commonly recognized as core competitive advantages to organizations. However, disparities between theoretical perspectives and application frameworks in the development and design of information systems has long been a topic of research in information management（IM）. In 2004, Hevner et al. referenced two subjects heavily relied upon in the information management field, namely, behavioral science and design science, to establish a design guide for developing information systems. This guide resolved issues such as user demand changes and difficulties regarding user demand fixation that apply to information system development（ISD）, as well as maintenance management and function updates and upgrades that follow the completion of information system. Hevner et al. contributed a significant breakthrough to the research of ISD, further introducing design science as a useful and valued subject in IM. This study was based on the mentioned research. Examining recent phenomena, we investigated how, with the influence of a rapidly changing environmental structure, the development and establishment of information systems can provide tolerance in adapting to environments, subsequently developing a system life cycle. By examining relevant literature, this study developed a multidimensional integrated system design reference framework that is essential for the development of a modeling based decision support system（MDSS） that corresponds to and accommodates situational changes. In this system’s design framework, a mutually effective cyclical relationship comprising model, scenario design, and information technology (IT) was established. In other words, this study created a model based on the essence of a problem, clarifying the essence of the problem to draw upon and obtain a maximum range for scenario designs, and then used techniques involving system IT to develop a knowledge processing model to solve all increased solving load, extended solving duration, or insolvable problems that could possibly be derived from the maximum range of scenario designs. We anticipate that this cyclical model will meet the demands of MDSS when encountering situational or scenario change, enabling users to conduct scenario case simulation analyses in a maximum range, extend the life span of their systems, and further increase the practical benefits from the development and practical application of information systems. This study focused on the development of a long-term power supply planning decision support system as a case study. By examining the practical development and establishment process of the case system, and conducting three simulation analyses on scenario cases related to recent energy policies, this study provided implications for decision support. These implications were used to verify the multidimensional integrated system design reference framework proposed in this study, and the results indicated an excellent reference value. The model—scenario design—IT cycle proposed in this study is an interlinked cyclical framework that continuously develops. In the future, this cycle can accommodate the demands of external environmental structures on MDSS. The addition of novel functions and components facilitates the system’s adaptation to the demands of external environmental changes, enabling the ability to independently evolve and develop, cascade information produced by the model, and develop novel techniques and information processing frameworks. Therefore, information is further developed into knowledge, allowing the design framework of MDSS to develop numerous case applications and enrich the significance of design science in ISD.
