Multiple viewpoint feature-based design : a framework for the panel furniture industry

Abstract

This thesis describes the creation of a feature-based design and manufacturing information system for the panel furniture industry. The system is developed around a framework of progressive levels of design information. Levels in the framework represent stages in the conception and production of panel furniture products. The framework addresses an identified need for improving design communication between the different departments or functions in the manufacturing process, including sales, marketing, concept design, detail design, planning, and production. Designing and specifying panel furniture products is a complicated task requiring specialist knowledge. The proposed framework provides a means of clearly documenting and communicating this knowledge. As well as supporting design and production processes, the framework also provides an ideal base to extend the use of feature-based modelling concepts from the design function, to planning, production, and particularly towards marketing and sales. Development of the framework begins with research and analysis of the specific stakeholding, or interests that each of the sales, marketing, concept design, detail design, planning, and production functions have in the design process. A method to help identify the relationships between these interests, entitled the Viewpoint Relationship Diagram is developed. This proposed method has been based on the quality function deployment technique. Once concepts for the framework levels have been defined, the viewpoint relationship diagram is also used to evaluate what opportunities exist for each level to best support the interests of all of the manufacturing functions studied. Each framework level is structured with design attributes that are appropriate to the requirements of the identified opportunities. Enplementing the framework proposal will assist the development of conscious competency with respect to design knowledge across all of the manufacturing functions. Further, several aspects of the framework have the potential to significantly reduce manufacturing costs by improving process efficiency. An important aspect of the work is the partnership that was formed with Australasia's largest panel furniture manufacturer, Criterion Manufacturing Ltd. This company co-operated extensively with the project, providing full access to staff and systems. Working with industry in this manner provided an excellent opportunity to apply the research and as a result several proposals from the work have been successfully implemented.
