This thesis contains product design modularisation and its potential for meeting manufacturing and marketing needs. The premiss is that product manufacturing organisations have failed to take advantage of the full potential, taking a reactive approach to modularisation within their product architecture and subsequent manufacture. The aims of this thesis are to develop a systems level framework for product and process integration, develop a strcutured methodology for design modularisation and finally, evaluate modularity through case analysis and software modelling.

Digital design tools and techniques facilitate efficiency gains, shorten development times, and aid collaboration between members of product development teams. As the range of digital tools available to the industrial designer increases, the aim of this research was to investigate the viability of a totally digital industrial design strategy and opportunities to employ the methods in design education. Published literature indicated a general lack of research in the use of digital design tools and media by industrial design students and practitioners. This research employed empirical surveys, which indicated that whilst the use of digital methods increased as the design solution progressed, practitioners were using digital tools/media more extensively than the students. The findings also revealed a negative reaction to a completely digital industrial design strategy and curriculum, despite the fact that the majority of practitioners believed. in the capacity of digital tools/media to replace conventional methods. Losing the spontaneity of paper-based sketching was identified as the main concern about a totally digital process and this issue was further investigated through a case study in which industrial/product design students employed the Tablet PC as a tool for concept generation. Student responses indicated overwhelmingly positive attitudes towards the use and capabilities of the Tablet PC as a tool for digital sketching and its use as a self-contained design tool. Following the first phase of empirical studies, a draft digital industrial design strategy was devised and presented to graduating students, academics and practitioners for feedback. Findings revealed that the majority of graduating students were receptive to the strategy and modifications applied in response to feedback. The research concludes that industrial design programmes are failing to fully avail of the breadth of advanced and emerging digital technologies that can be used during practice. Despite the fact that the majority of interviewees felt that the digital industrial design strategy was feasible, cost and the resistance of academics who had an interest in the use of conventional tools was holding back educational progress. Recommendations for curriculum development have been identified for a more extensive introduction to, and use of, digital tools.

This thesis describes the results of research into provision of Production Activity Control (PAC) in Computer Integrated Manufacturing Systems for manufacture of discrete parts. The role and environment of PAC systems is described, against the background of development of the discrete parts manufacturing industry. Strategies and architectures for building PAC systems are reviewed, in terms of the goals of PAC systems, and the categorisation of existing design approaches. A novel design for a PAC system is presented. A model of manufacturing is described upon which the system design is based, and which defines the applicability of the proposed system. The heterarchical, data-driven system architecture is explained, and the way in which the system's design supports the various aspect of PAC functionality is described. A simple example is presented to illustrate the workings of the system as it accepts production orders and controls production. An experimental implementation of the system is described, and the results discussed. Recommendations for future implementations are'made in further discussion, stemming from the experiences of this experimentation, and from consideration of wider issues in the development of manufacturing technology. The thesis concludes with a brief statement of achiever nts, an'' some recommendations for directions of further research.
