Item Metadata onlyA cost-effective knowledge-based reasoning system for design for automation.(Professional Engineering Publishing, 2006-01-01) Shehab, Essam M.; Abdalla, HassanDesign for assembly automation (DFAA) is an important part of the concurrent engineering strategy for reduction of product manufacturing costs and lead times. An intelligent knowledge-based system (KBS) for design for automation and early cost modelling within a concurrent engineering environment has been developed. This paper focuses upon the development of the design for an assembly automation system. The system framework encompasses an extensive knowledge-based reasoning system, a CAD system, a design analysis for automation module, a design improvement suggestion module, and a user interface. The development process of the system involved three main stages: creating the KBS, developing the design improvement module, and integrating the KBS with the CAD system. The developed system has the capability to: (a) select the most economic assembly technique for the product at an early design stage; (b) estimate the assembly time and cost for manual, automatic, and robotic assembly methods; and (c) analyse the product design for automation and provide the designers with design improvement suggestions of a product to simplify assembly operations without any compromise of the product functionality. The above capabilities of the system have been demonstrated and validated through a real case study. Item Metadata onlyA distributed e-commerce system for virtual product development teams.(Professional Engineering Publishing, 2002-01-01) Anderson, Neil; Abdalla, HassanThis paper presents a distributed information system that facilitates virtual multidisciplinary product development activities. A growing problem today for many companies is that of facing up to increasing global competition, increasing the importance of delivering the right product at the right time and at the least cost. To enable a company to provide competitive services, concurrent engineering methods are employed progressively more often. However, a truly effective concurrent engineering team requires specialists in a wide variety of occupations and skill bases. Effective communication and exchange of information between members usually require not only face-to-face meetings but also highly advanced tools. Various tools have been developed in the past with the premise of facilitating effective communication. However, these have realistically only covered a subsection of the total product development life-cycle. The work presented here displays an approach to the problem in terms of an Internet-based system, which provides a mechanism to allow integrated information sharing from the initial concepts through to the realization and the marketing of a product. The system effectively removes the barriers between people and incompatible computer systems and resulting from non-standardization.
