The paper presents some of the conflicting advice offered to designers on one particular topic in accessibility: the choice of font size for visually impaired people. This creates practical difficulties for designers when trying to apply the advice.

Multidisciplinary Parameter Coordination Based on Constraints Network Agent Modeling

January 2006

Modeling and coordination are two important parts in multidisciplinary design process of a complex product. In this paper, firstly, agent-based constraints network approach is presented to model multidisciplinary parameter design process. Secondly, a general consistency algorithm is designed to predict conflict and refine the intervals for parameter coordination, which verify the design process ...

The method is demonstrated by a bogie parameter design problem

Multiple objective decision-making for material and geometry design

December 2016

During the design process for a product, materials are either selected or designed to meet the desired requirements. In material selection the outcome is that typically the ideal solution is not always chosen. Also, because of the conflicting nature of materials characteristics, improvement of material properties usually does not meet the expected requirements, hence material design benefits from ... [Show full abstract] multi-objective optimization. However, despite the complexity, the final product can benefit from simultaneous material and structural optimization.

Ensure valid design constraints throughout the design process

April 2005 · Edn -Boston then Denver then Highlands Ranch Co-

Tools used to ensure constraints validity throughout the building of increasingly complex circuit designs are discussed. Designers need an approach that manages all aspects of the design-constraint problem throughout the design process, from RTL to final netlist, addressing analysis, generation, and validation of constraints. The constraints methods must detect the conflicts in clock ... [Show full abstract] specification, boundary conditions, and exceptions between block- and top-level constraint in a hierarchical context. A complete constraint method should be able to map the RTL to a gate-level design so that designers can validate the constraints, accounting for RTL assumptions.

Design for Runway Conditions

September 1963 · Journal of the Royal Aeronautical Society

J. W. H. Thomas

The designer's task is always to choose the best compromise to meet the various conflicting requirements put upon him. This task is eased when these requirements and ways of meeting them are expressed precisely in numbers, which is so in most performance work, but rarely true of safety or reliability. In these latter areas the feedback of operational information shows when a problem exists and ... [Show full abstract] how important it is. For existing aircraft a solution must often be sought by ad hoc tests before the results of fundamental research are available.

Declarative Interaction Towards Evolutionary User Interface Prototyping

May 2018

Cristian Bogdan

This paper examines the potential of describing interactive systems in a declarative manner with concepts familiar to both developers and designers. Such declarative interaction descriptions will enable evolutionary prototyping processes. This new type of design and development processes that can emerge with declarative interaction is described along with benefits for human-centred system design. ...

Design considerations for multipurpose bidirectional reflectometers

December 1991 · Proceedings of SPIE - The International Society for Optical Engineering

A bidirectional reflectometer designed for obtaining both signature data and optical component scattering information must satisfy a wide range of measurement requirements and sometimes conflicting requirements and criteria. The basic definition of bidirectional measurement is reviewed; the design approaches, measurement geometries, measurement procedures and techniques, recommended for a ...

Parameter coordination and optimization for collaborative design based on the constraints network

April 2007 · The International Journal of Advanced Manufacturing Technology

This paper presents an approach based on the constraints network to support collaborative design. Firstly, from the point of view of collaborative design, the model of the constraints network for coordination and optimization is studied. Secondly, a general consistency algorithm is designed to predict conflict and refine the intervals for parameter coordination, which verify the design stage ...

Finally, a constraints-network-based parameter optimization model is established, and the multiobjective optimization approach is presented. The method is demonstrated by a bogie parameter design problem.

On the Design of Low-Density Parity-Check Codes

December 2011 · IEEE Vehicular Technology Magazine

This treatise provides an overview of the conflicting design tradeoffs of low-density parity- check (LDPC) codes and thus advocates a more holistic approach to their design. In doing so, this article encourages code designers to aim for codes that achieve the highest number of desirable attributes, rather than simply designing codes that closely approach the ultimate bounds but possess ... [Show full abstract] impractical hardware implementations. However, the intricate dependencies that exist between the aforementioned tradeoffs does not make this a simple task at all.

In this dissertation I will explore the relationship between the designer, the Circular Economy (Ellen Macarthur Foundation 2017) and the products and companies within which they interact. The conflict between the needs of the planet and the need for profit in terms of design and the part designers make in resolving this conflict will be questioned. Examples of these conflicts in action and some ... [Show full abstract] of the solutions offered will be investigated and the drivers behind these actions discussed.

Design of PID Controllers Using Multiobjective Genetic Algorithms

April 2000 · IFAC Proceedings Volumes (IFAC Papers-OnLine)

The design or a PID controller is a multiobjective problem. A plant and a set of specifications to be satisfied are given. The designer has to determine a controller such that the feedback interconnection of the plant and the PID controller satisfies the specifications. The specifications are usually competitive and any acceptable solution requires a trade-off between the conflicting objectives. ... [Show full abstract] In this paper, we present an approach for the design of PID controllers with multiple objectives using genetic algorithms.

Communicating preferences in multiple-criteria decision-making: The role of the designer

March 2001 · Journal of Engineering Design

P. Sen

Design decisions, in general, involve the balancing of potentially conflicting requirements as progress is made towards obtaining the most preferable design for a given application. Two important aspects of this procedure are: (i) the ability to create competing designs, and (ii) to arrange a preference ordering over the same designs. This paper deals with the latter of the two aspects to examine ... [Show full abstract] how alternative expressions of designer preference influence methodological developments for the generation and ranking of candidate designs.

A weak product on partially ordered sets to define a compromise between multiobjective optimization...

June 2009

Multidisciplinary design optimization (MDO) deals with complex engineering problems which are decomposed into several subproblems called disciplines. The disciplines are often hierarchically organized. Moreover, each discipline may have many conflicting objectives to achieve at the same time. Thus, at each level of the hierarchy, trade-offs have to be found between multiobjective optimization ... [Show full abstract] problems. Multiobjective multidisciplinary methods designed to solve hierarchical multiobjective optimization problems such as EM-MOGA, MORDACE or COSMOS are searching for the whole Pareto set which corresponds to the multiobjective optimization problem that bring all the objectives of the problem together. But the solutions are just in a subset of the whole Pareto set. In this paper, we propose a definition of compromise between disciplines which are multiobjective optimization problems.
