Conceptual process design phase is of prime importance to the performance and the profitability of a new or retrofit process. It is also a highly complex task with a large number of process alternatives, a large variety of requirement specifications and large differences in temporal and spatial scales. Therefore, it is essential to continuously improve design methods. The research should not on...

SUPPORTING FUNCTIONALITY-BASED DESIGN IN COMPUTER-AIDED DESIGN SYSTEMS Obinna Stan Muogboh, PhD University of Pittsburgh, 2003 Designs are conceptualized in terms of the functions they need to accomplish. The need for a new product design arises as a result of the identification of a new functionality to be accomplished by the product. That is, design is functionality driven. However, existing ...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract Despite the development of a variety of decision-aid tools for assessing the value of a conceptual design, humans continue to play a dominant role in this process. Researchers have identified two major challenges to automation, namely the subjectivity of value and the ...

Multiple-view feature modelling is used in concurrent engineering. A shortcoming of current implementations is that they can only support low-level geometry-based product development phases, because they use form feature models. In order to overcome this shortcoming, we will use enhanced feature models, which are built from features that are defined as an aspect of a product that has some funct...

The synthesis of the three-dimensional morphology of a building is one of the most important tasks in architecture. Space planning and morphology are of the most interesting and complex of architectural design problems. Architectural design is guided by the constraints on the spatial composition and the morphology of the final building. During the conceptual phase problems are characterised by ...

Abstract Additive manufacturing (AM), which was first applied for rapid prototyping, is now becoming a real option small-batch production of final products. Further expansion AM closely correlated to costs. can only become competitive traditional methods if product designed already from the beginning as it an expensive technology that should be adds enough value product. The aim this paper incr...
