In the modern globar market and manufacturing environment, industries have to put more focus on reducing time to market while reducing production costs on the development of new products. Collaborative product development is a growing trend that is being used to answer some of that problem. However, literature research has revealed that there are only a small number of researches that has talke...

In this paper we present strategies to handle complexity during the conceptual phase of ship design. We introduce the issue by summarizing key ship design advancements during the last six decades, showing the growth in information, which leads to a more complex system. A definition of complexity based on the amount of information necessary to define the system is then discussed, placing the shi...

Product environmental impact reduction efforts largely focus on incremental changes during detailed design. Application of automated concept generation using a design repository and integral life cycle assessment approach is explored to evaluate and reduce environmental impacts in the conceptual phase of product design.

Following the feasibility demonstration of the novel CLIC technology and the publication in 2012 of a CLIC Conceptual Design Report for a Multi-TeV Linear Collider to be built in stages, a new phase towards a technical design is being launched by a global collaboration of volunteer institutes. This paper reviews the status and plans of the CLIC study outlining the developments planned for the n...

 Conventional CAD systems have not yet proven their ability to provide support for activities which characterise the early conceptual phase of design. We propose to refer to this set of capabilities of the human designer in conventional design as, design prototyping. We define the theoretical limitations of current CAD systems for supporting design prototyping, and postulate the potential of f...

SPACECRAFT DESIGN PROCESS Regardless of how long it takes, spacecraft design and development typically occur in phases identified as: requirements definition, conceptual design, preliminary design, and detailed (or critical) design. These phases and their sequential relationships are shown in Figure 10-1. The design and development of a spacecraft is an engineering process divided into identifi...

The Water-Cooled Lead–Lithium Breeding Blanket (WCLL BB) is one of the two blanket concept candidates to become driver EU-DEMO reactor. design was enacted with a holistic approach. influence that neutronics, thermal-hydraulics (TH), thermo-mechanics (TM) and magneto-hydro-dynamics (MHD) may have on were considered at same time. This new approach allowed for team create WCLL BB layout able compl...

Construction projects usually encompass numerous disciplines, requiring the integration of knowledge from civil, mechanical, electrical and other engineering domains. Some researchers contend that the integration of construction knowledge and experience at the early design phase would improve the overall project performance. Domination of tacit knowledge during design phase of building projects...

in this paper, a new approach is proposed for the optimum design of single-phase induction motor. by using the classical design equations and the evolutionary algorithms such as genetic algorithms (ga), particle swarm optimization (pso) and modified particle swarm optimization (mpso), a single phase induction motor (spim) was designed with the maximum efficiency. the finite element method (fem)...
