We present a fundamentally different approach to orthogonal layout of data flow diagrams with ports. This is based on extending constrained stress majorization to cater for ports and flow layout. Because we are minimizing stress we are able to better display global structure, as measured by several criteria such as stress, edge-length variance, and aspect ratio. Compared to the layered approach...

This paper presents an overview of a design environment for digital filters. We discuss ongoing work as well as previously developed parts of the design flow. The purpose with this design environment is to improve the design efficiency and thereby be able to increase the knowledge in the area of design and implementation of energy efficient digital filters. The design environment includes all d...

A model of layout in illustrated documents must be informed by the rhetorical structure of the content. However, real-life production constraints often force an ‘imperfect’ realisation of the rhetorical structure on the page. Navigational elements must consequently be introduced into the layout to support the reading path. Layout structures, including the placement of the navigational elements,...

The aim of this research is the development of an innovative approach to support company upgrades, reorganization and new facility establishment. This approach is focused on combining layout engineering with the use of simulation and optimization; this combination is very important because allows to reorganize the whole layout and production processes and flows and to measure the results in the...

With increasing production costs and constraints, demand has increased for manufacturers to minimize maintenance cost and product transport time. We address some aspects of this problem by examining how to choose the optimal layout of stations (machines or buffers) in a production facility based on how the station layout affects the maintenance and product transport times. Specifically, we cons...

Facility layout design is a strategic issue and has a significant and lasting impact on the efficiency of a manufacturing system. An ideal facility layout provides the optimum relationship among output, floor area and manufacturing process. Traditionally, the facility layout problem is solved using many methods like heuristics, Mathematical programming, Knowledge based approaches etc. This pape...

the integration of an approximate model and a clonal selection algorithm (csa) is considered to one of the most effective ways to solve complex optimization design problems in engineering. in this study, first, a process for developing an approximate model and the principles of clonal selection algorithms were presented. then, a variotherm temperature injection mold used to produce a large liqu...

As MOEMS (Micro-Opto-Electro-M echanical Systems) transition from laboratory curiosities to production products inserted into telecommunication systems, a top down design flow is necessary to minimize time-to-market. We present a structured-custom approach for MOEMS design based on the concept of using parameterized behavioral models as a means to improve and speed up the design process. This a...
