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.

624 and Software development

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.

020 and Information system prototyping

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.

Decision support systems., Resource allocation., and Expert systems (Computer science)

Effective resource management requires tools and decision aides to help determine users' needs and appropriate assignment. The goal of this research was to design, implement, and test technological tools that, even in a dynamic environment, effectively support the matching of users and resources. The context of the investigation is the Information Center, the structure used to manage and control the computing resources demanded by end users. The major contributions of the research lie in two areas: (1) the development and use of a knowledge acquisition called Resource Attribute Charts (RAC), which allow for the structured definition of the resources managed by the IC, and (2) the design, implementation, validation, and verification of the transportability of Information Center Expert, a system that supports the activities of the IC personnel. Prototyping, the system development methodology commonly used in software engineering, was used to design the general architecture of the knowledge acquisition tools, the knowledge maintenance tool, and the expert system itself. The knowledge acquisition tools, RAC, were used to build the knowledge base of ICE (Information Center Expert). ICE was installed at two corporate sites, its software recommendations were validated, and its transportability from one location to another was verified experimentally. The viability of a rule-based consultation system as a mechanism for bringing together knowledge about users, problems, and resources for the purpose of effective resource management was demonstrated.

621.3822 and TK5101 Telecommunication

Distributed, computer based communication is becoming established within many working environments. Furthermore, the near future is likely to see an increase in the scale, complexity and usage of telecommunications services and distributed applications. As a result, there is a critical need for a global Directory service to store and manage communication information and therefore support the emerging world-wide telecommunications environment. This thesis describes research into the design of distributed Directory services. It addresses a number of Directory issues ranging from the abstract structure of information to the concrete implementation of a prototype system. In particular, it examines a number of management related issues concerning the management of communication information and the management of the Directory service itself. The following work develops models describing different aspects of Directory services. These include data access control and data integrity control models concerning the abstract structure and management of information as well as knowledge management, distributed operation and replication models concerning the realisation of the Directory as a distributed system. In order to clarify the relationships between these models, a layered directory architecture is proposed. This architecture provides a framework for the discussion of directory issues and defines the overall structure of this thesis. This thesis also describes the implementation of a prototype Directory service, supported by software tools typical of those currently available within many environments. It should be noted that, although this thesis emphasises the design of abstract directory models, development of the prototype consumed a large amount of time and effort and prototyping activities accounted for a substantial portion of this research. Finally, this thesis reaches a number of conclusions which are applied to the emerging ISO/CCITT X. 500 standard for Directory services, resulting in possible input for the 1988-92 study period.

design, computer, work, industrial democracy, skill, tool, labor process, language-game, and Scandinavia

This thesis is an inquiry into the human activity of designing computer artifacts that are useful to people in their daily activity at work. The emphasis is on opportunities and constraints for industrial democracy and quality of work. First, the philosophical foundation of design of computer artifacts is con­sidered. The need for a more fundamental understanding of design than the one offered by rationalistic systems thinking is argued. The alternative design philosophy suggested is based on pragmatic interpretations of the philosophies of existential phenomenology, emancipatory practice, and or­dinary language. Design is seen as a concerned social and creative activity founded in our traditions, but aiming at transcending them by anticipation and construction of alternative futures. Second, it is argued that the existing disciplinary boundaries between natural sciences, social sciences and humanities are dysfunctional for the subject matter of designing computer artifacts. An alternative under­standing of the subject matter and a curriculum for its study is discussed. The alternative emphasizes social systems design methods, a new theoreti­cal foundation of design, and the new potential for design in the use of prototyping software and hardware. The alternative also emphasizes the need to learn from other more mature design disciplines such as architec­tural design. Towards this background, and based on the practical research in two projects (DEMOS and UTOPIA), a view on work-oriented design of computer artifacts is presented. This concerns, thirdly, the collective resource approach to design of com­puter artifacts - an attempt to widen the design process to also include trade union activities, and the explicit goal of industrial democracy in design and use. It is argued that a participative approach to the design process is not sufficient in the context of democratization. However, it is suggested that it is technically possible to design computer artifacts based on criteria such as skill and democracy at work, and a trade union investigation and negotia­tion strategy is argued for as a democratic and workable complement to traditional design activities. Finally, a tŒil perspective - the ideal of skilled workers and designers in coopération designing computer artifacts as tools for skilled work is consid­ered. It is concluded that computer artifacts can be designed with the ideal of c rail tools for a specific profession, utilizing interactive hardware devices and the computer's capacity for symbol manipulation to create this resemblance, and that a tool perspective, used with care, can be a useful design ideal. However, the ideological use of a tool metaphor is also taken into account, as is the instrumental blindness a tool perspective may create towards the importance of social interaction competence at work.

Group decision making. and Multiple criteria decision making.

In modern organizations where managers must constantly be dealing with an overload of information, it is often observed that participants in group decision processes either are not clearly aware of their specific preferences or that they are not capable of properly formulating those preferences. When this happens, inconsistent or incomplete expression of personal preferences and their use in decision making may lead to an unjustifiable outcome for the group. Due to this problem, the strengths and effectiveness of GDSS-supported group meetings may, in some situations, not be apparent. This dissertation develops a new approach to supporting group decision making, focusing on preference knowledge of individual participants in a group. A system architecture for the design of an MCDM (Multiple Criteria Decision Making) GDSS which facilitates the process of eliciting, formulating, utilizing, aggregating, and analyzing preferences for individuals within groups is presented. The architecture integrates multi-criteria decision making paradigms with a group decision support environment. A prototype has been developed in order to demonstrate the design feasibility of an architecture that centers around four phases of choice making: alternative generation, preference specification, alternative evaluation, and preference aggregation. The prototype is designed to support managerial choice and judgment processes in collaborative meetings. The intended problem domain of the model is semi-structured managerial decisions for which decision variables (attributes) can be represented in quantitative terms to some extent, yet for which evaluation of alternatives requires a high degree of intuition and personal analysis. The process of prototyping the proposed architecture and the results from a qualitative study have provided some instructive conclusions relating to MCDM GDSS design: (1) support for human choice strategies can be integrated into a GDSS, (2) appropriate management of preferences of group participants will facilitate collaborative decision processes, (3) hierarchical decomposition of a decision problem can provide structure to a problem and thereby reduce problem complexity, and (4) managerial decisions are appropriate problems to which the current approach can be applied.
