Aerospace industry is a value-added and technology integrated industry. Sheet metal parts are important portion of aerostructures. The sheet metal production line combines five different routing types together. This study tries to make a comparison between job shop layout and cellular layout with lean concept. According to precedence diagram of sheet metal fabrication process, the model and mea...

The Operating Theater (OT) is known to be a fluctuating production system. The unpredictability of populations’ needs has an impact on the required human and material resources and makes the Operating Theater a dynamic environment. Thus, the use of dynamic models is getting more realistic to solve OT Layout Problem (OTLP). While solving Dynamic OTLP, Real-life Operating Theater (OT) sizes are l...

The paper studies a unit cell mismatch scrambling method for high-resolution unary DAC based on virtual 3-dimensional (3D) layout, to improve its spurious-free dynamic range (SFDR) communication applications. This can be implemented with relatively simple interconnections and circuits, compared that the 2-dimentional (2D) layout.

Cellular Manufacturing (CM) has been emerged as a strong approach for improving operations in batch and job shop environments. In cellular manufacturing, Cell formation, static layouts, dynamic layouts are the prime areas for achieving the optimal cellular layout for any problems. In this paper it is decided to review the recent research work in this particular area and to project the effective...

In this paper, we develop a new mathematical model that integrates layout configuration and production planning in the design of dynamic distributed layouts. The model incorporates a number of important manufacturing attributes such as demand fluctuation, system reconfiguration, lot splitting, work load balancing, alternative routings, machine capability and tooling requirements. In addition, t...

This paper1 presents an object-oriented technique for specifying a dynamic layout of visual objects in a Graphical User Interface (GUI) . This technique deals with complex dynamics of: non-dependence on physical appearance and size of an object, multilingual objects, resizable objects, extendable objects, and potentially resizable windows. Dynamic change due to these causes the physical positio...

Most GUIs are specified in the form of source code, which hard-codes information relating to the layout of graphical controls. This representation is very lowlevel, and makes GUIs hard to maintain. We suggest a reverse engineering approach that is able to recover a higher-level layout representation of a hardcoded GUI using the Auckland Layout Model, which is based on the mathematical notion of...

Layout problems are found in several types of manufacturing systems. Typically, layout problems are related to the location of facilities (e.g., machines, departments) in a plant. They are known to greatly impact the system performance. Most of these problems are NP hard. Numerous research works related to facility layout have been published. A few literature reviews exist, but they are not rec...
