Comparative analysis of top-down and bottom-up methodologies for multi-agent system design [PDF]

open access: possibleProceedings of the fourth international joint conference on Autonomous agents and multiagent systems, 2005
Traditionally, top-down and bottom-up design approaches have competed with each other in Algorithmics and Software Engineering. In the top-down approach, design process starts with specifying the global system state and assuming that each component has global knowledge of the system, as in a centralized approach.

Ordering effects in nested ‘top-down’ and ‘bottom-up’ contingent valuation designs

Ecological Economics, 2003
Abstract Within a contingent valuation (CV) survey ordering effects are defined where responses to a given question vary in a theoretically unanticipated manner according to the positioning of that question relative to others in the survey instrument.

Multimodal Microorganism Development: Integrating Top-Down Biological Engineering with Bottom-Up Rational Design

Trends in Biotechnology, 2020
Biological engineering has unprecedented potential to solve society's most pressing challenges. Engineering approaches must consider complex technical, economic, and social factors. This requires methods that confer gene/pathway-level functionality and organism-level robustness in rapid and cost-effective ways.

Modelling an ongoing design process utilizing top-down and bottom-up design strategies

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2008
The product design process plays a central role in ensuring that new products are realized with improved quality, in a short lead-time and with costs kept to a minimum. It is identified that making decisions dynamically on how the design process should proceed is not trivial.

Bottom-up, Top-down? Connecting Software Architecture Design with Use

2008
Participatory design has traditinally focused on the design of technology applications or the co-realisation of a more holostic socio-technical bricolage of new and existing technologies and pratices. 'Infrastructural' design issues like software architectures, programming languages, communication, security, and resource models do not seen to be in ...

Designing redox metalloproteins from bottom-up and top-down perspectives

Current Opinion in Structural Biology, 2003
The design of redox-active metalloproteins has been approached from two different directions. The de novo design approach has recently reached an important stage, at which structural information on several different designed metalloproteins has been obtained. This new information highlights the real challenge of this approach.

Top-down or bottom-up? – How environmental benchmarks can support the design process

Building and Environment, 2019
Abstract Buildings are responsible for a large share of greenhouse gas (GHG) emissions. The use of Life Cycle Assessment (LCA) during the design phase can help to improve the environmental performance of buildings. However, designers and clients find it difficult to set environmental performance targets and interpret the results obtained through LCA ...

Mechanistic Pavement Design Considering Bottom-Up and Top-Down-Cracking

2012
Pavement design and pavement life-time estimation are generally realized by using mechanistic-empiric pavement design tools. In this paper an improved design procedure is presented that integrates bottom-up-fatigue-cracking and low-temperature-induced top-down-fatigue-cracking in a narrow time-scale. Considering a design period of decades (e. g.

Teaching Top-Down ASIC/SoC Design vs Bottom-Up Custom VLSI

2007 IEEE International Conference on Microelectronic Systems Education (MSE'07), 2007
In the fast paced world of IC design, companies strive for ways to create competitive, robust designs, while delivering speedy time-to-market results. A top-down design flow provides a fast, results oriented design methodology, but, at most Universities, the strong legacy of the Mead/Conway approach has lead to custom methods being the default way to ...
