應用TRIZ分析台灣空運業延長路上服務時間之研究 / Innovation is the core for service industry. There are different phases for service innovation; it is an evolving to the end user; service extension is one kind of the innovation. However, the service innovation is difficult to be evaluated, which is intangible; it’s about the perception form the end users. Finding a practical way to scientifically describe or compare “perception”, “feeling”…etc becomes an interesting topic for studying. The case we have is about the Service extension of Air cargo business. The issues for the service extension include: (1) how can the information technology support the service extension? (2) how is the cost effectiveness (3) how is the limitation and impact for the service extension? (4) how does the market feedback for the service extension? The methodology we used is TRIZ, which is applied well in the hardware innovation. First, TRIZ is a systematical way to clarify the status quo of the operation system; the possible solution can be come out from TRIZ’s systematically analysis! In the last, TRIZ is also applied for the solution evaluating. In this study, TRIZ’s Contradiction analysis is used for constructing and identifying the issues for the service extension; the 40 TRIZ principles is used for working out and evaluating the possible solutions. Key word: Service innovation, Service Extension, Air cargo, Express, TRIZ Contradiction Analysis, TRIZ principles.
