The layout design problem is a kind of nesting problems that is naturally NP-hard and very difficult to solve. Layout designing of machine is even more difficult because of its nesting items are actually machine parts that have both irregular shapes and complex constraints. A feasible way to solve machine layout problem is to employ ameliorative algorithms, such as simulated annealing algorithm...

Increasing global competition has enforced all members of supply chains to optimize their activities to achieve high performance and customer satisfaction. A company can improve its supply chain performance in terms of responsiveness and efficiency by means of good facility layout design. Facilities are the places in the supply chain network where product is stored, manufactured, assembled or f...

Research on the integrated NC conceptual layout design (I-NCC) concerned with a broader area of interests. The key issues of I-NCC system are associated with NURBS and agent. Firstly, formulas for the derivatives and normal vectors of non-rational B-spline and NURBS are proved based on de BOOR’s recursive formula. Compared with the existing approaches targeting at the non-rational B-spline basi...

The layout design is a ubiquitous problem in engineering and design that is intrinsically knowledge-intensive, complex, vague, ill-comprehended and ill-structured. Inadequate information processing capabilities in tandem with various subjective user preferences, design constraints, and fitness objectives often hamper the acquisition of a superior solution. Consequently, the incorporation of sub...

Our goal is to provide a Multi-Perspective viewpoint interactive interface media of sketch-based for rapid get spatial layout in Show-Window. In traditional way, designer is used to describe concept in early phases of design by Single-Perspective viewpoint via sketch in Show-Window design environment. It usually makes blind spot of spatial vision in early phases of design because it can’t break...

This note investigates the role of problem formulation in avoiding conputal difficulties. The proposed notion is applied to trusses with stress constraints and to an alternative general approach to topology design.

This paper translates the competition content and assessment standards of Skill Graphic Design Technology WorldSkills Competition into training for skilled talents, results are translated daily teaching results. Through researches, new technology, skills can be widely applied to benefit all students so as cultivate highly talents with high comprehensive quality strong innovation consciousness.

In the past few years, several tools for the automation of the analog integrated circuit (IC) cell and system layout design, with application on both new and reused designs have emerged. Yet, most of the layout design is still handmade, essentially because analog designers want to have total control over the different design options, and also, due to the fact that current fully automated genera...

Due to the increased competition in manufacturing industries play a driving force towards reducing the manufacturing costs by efficient design of facility layout. The success of manufacturing industries depends on the design of the facility that is able to adapt quickly and effectively for any changes in market requirements, technological changes, etc. The Facility Layout Problem (FLP) is a com...

In this paper, a new method to implement the LVS check in different IC design software, without using specialized LVS software, is presented. The main advantage of the proposed method consists in the fact that all types of checkings (DRC and LVS) can be easily performed, without using specialized parameters extraction software, which is very expensive and difficult to implement. The method prin...
