碩士 南台科技大學 工業管理研究所 101 On the issue of factory yield, the performance of yield affects production cost directly. How to feed back product quality status effectively and immediately is the key project of yield enhancement. This study is using Prototyping to develop real time On-line Information Systems for yield management, the integrated and subject-oriented structured data with Data Mart and On-line Information Processing Technology. Using the structure of subject-oriented information to reduce the response time of system and improve system’s performance, helping the case to do real time yield monitoring, resolving the issue of quality abnormal situation which could not react timely and yield rate of manufacturing management. By validating and tracking the case, real time On-line Information Systems can transfer information rapidly, shorten the response time of quality abnormal situation, also decrease the cost of the production, and the system developed can shorten the reactive time when the case is doing yield monitor.
碩士 國立高雄應用科技大學 模具工程系 101 Apollo solar car team’s solar car shape design in mostly based on race-type mainly designed for single driver’s seat, with three wheels. Motor company’s solar car development is still at the conceptual design stage. Currently, the race-type solar car is beginning to move toward the commercialized requirements which tires must be four and comply with the specifications of the city car, and consider the human factors engineering design. A metropolis-type solar car, widening interior space to make passengers comfortable, should have the shape with lower aerodynamic drag coefficient(Cd) to meet the requirement of energy consumption. Both of the numerical simulation and the experimental measurements are used to design and verify the models in this study. For comparing the drag coefficient, the four shape designs of solar city cars, equipped with two upright seats, tested under various speed, attack angles and deflection angles inside a wind tunnel. The ANSYS ICEM-CFD software used to build the appearance and mesh for the test models. The numerical simulation, used ANSYS FLUENT CFD, calculated and obtained the optimal shape of the car with a lower Cd. The test models, scaled 1:25, manufacture by the rapid-prototyping(RP). For each model, the values of Cd can be determined by tested in a low speed open-loop wind tunnel. The results are shown the Cd-value decreases when car speed up, but the lift coefficient increases while car speed in 36-108 km/hr. In addition, the Model-C have better Cd-value, 0.33802, than others. The results of the wind tunnel experiment are consistent with that of the numerical simulation. The results of the research will be valuable to develop the metropolis-type solar car in the future.
This thesis examines alternative prototyping processes as a means of implementing manufacturing information systems in a small to medium sized batch process manufacturing company. Prototyped IS (Information Systems) ate compared to other systems designed and implemented according to the traditional Systems Development Life Cycle model. Action research is used in conjunction with an IS case study framework. as the strategy to provide a rich analysis of the power, political, organizational and business effects resulting from the prototype implementations. Survey and structured interview methods are used to assess the rate of spread and extent of prototyped versus non prototyped IS applications. Perceptions of IS user managers from both prototyped and non prototyped systems are measured using an IS user satisfaction measurement tool. Alternative manufacturing information systems implementation methodological choices are examined resulting in the identification of three paradigms important to the appropriate selection of implementation methodology dependent on manufacturing environment context: Systems ProblemlLearninglAction (SPLA); Systems Engineering; and Systems Architecture. Prototyping is identified as belonging to the SPLA paradigm characterized by 'soft' systems methodologies orientated to problem solving by an iterative process of learning. Conclusions from this multi-disciplinary research enquiry are that prototyping is a viable implementation methodology with defInite performance improvements over traditional methodologies. A five dimensional framework for prototyping manufacturing information systems is proposed. The five dimensions: IS Strategy; Organizational; User; Business; and Prototyping provide a mechanism (or planning and managing the prototyping process. Recommendations are made for more research to be carried out into the derivation of a structure for the evolutionary prototyping process, for more investigation into the problems of early implementation of prototypes, whilst maintaining technical and quality integrity, and for more field studies to identify potential implementation contexts of the prototypingframework.

005 and Question-answering systems : Interactive computer systems
With ever cheaper and more powerful technology. the proliferation of computer systems, and higher expectations of their users, the user interface is now seen as a crucial part of any interactive system. As the designers and users of interactive software have found, though, it can be both difficult and costly to create good interactive software. It is therefore appropriate to look at ways of "engineering" the interface as well as the application. which we choose to do by using the software engineering techniques of specification and prototyping. Formally specifying the user interface allows the designer to reason about its properties in the light of the many guidelines on the subject. Early availability of prototypes of the user interface allows the designer to experiment with alternative options and to elicit feedback from potential users. This thesis presents tools and techniques (collectively called SPI) for specifying and prototyping the dialogues between an interactive system and its users. They are based on a formal specification and rapid prototyping method and notation called me too. and were originally designed as an extension to me too. They have also been implemented under UNIX*. thus enabling a transition from the formal specification to its implementation. *UNIX is a trademark of AT&T Bell Laboratories.
This thesis is concerned with the use of prototyping during the development of information systems. Prototyping is a process which involves early practical demonstration of relevant parts of the desired system. This is carried out with a view to improving both the quality and timeliness of the target system. The quality of an information system is largely determined by its adequacy as a tool for human users. Prototyping serves to enhance the communication between developers and users, and through this to increase the suitability of the resulting information system. An investigation into the traditional phase oriented approach to systems development reveals that in certain circumstances it can result in incorrect or at best disappointing systems. The prototyping approach is examined as a possible alternative. Particular attention is paid to its use with respect to typical characteristics of information systems. This is followed by an investigation into all aspects of prototyping. One aspect, that of the construction of prototypes, is dealt with separately and includes an examination of a variety of tools and techniques. Three of these approaches form part of an experiment in building prototypes. Each method is used to build prototypes of the same system. This provides the opportunity to compare approaches in terms of time, cost, and ease of maintenance, with the existing system. Prototyping is used during the development of a genuine system in a commercial environment. Special consideration is given to both the organisation and the control of prototyping. This project is closely monitored and documented in detail. In conclusion, recommendations are made concerning the use of prototyping during information systems development. Further research areas are also highlighted.
