The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
The decision-matrix method, also Pugh method or Pugh concept selection, invented by Stuart Pugh, [1] is a qualitative technique used to rank the multi-dimensional options of an option set. It is frequently used in engineering for making design decisions but can also be used to rank investment options, vendor options, product options or any ...
Design optimization applies the methods of mathematical optimization to design problem formulations and it is sometimes used interchangeably with the term engineering optimization. When the objective function f is a vector rather than a scalar , the problem becomes a multi-objective optimization one.
Model-based design provides an efficient approach for establishing a common framework for communication throughout the design process while supporting the development cycle . In model-based design of control systems, development is manifested in these four steps: modeling a plant, analyzing and synthesizing a controller for the plant,
A further argument supporting the waterfall model is that it places emphasis on documentation (such as requirements documents and design documents) as well as source code. [ citation needed ] In less thoroughly designed and documented methodologies, knowledge is lost if team members leave before the project is completed, and it may be difficult ...
In civil engineering, design choices typically derive from basic principles of materials science and structural design. A suspension bridge, for example, uses the fact that steel is extremely efficient in tension , while a prestressed concrete bridge takes advantage of concrete 's relatively low cost by weight and its ability to sustain high ...
Research suggests that there is a need to provide computer support that will supply clear and complete design knowledge and also facilitate designer intervention and customization during the decision-making activities in the design process. [16] For example, WebCADET [17] is a design support system that uses distributed Web-based AI tools.
The process is characterized by the alternation of divergent and convergent thinking, typical of design thinking process. To achieve divergent thinking, it may be important to have a diverse group of people involved in the process. Design teams typically begin with a structured brainstorming process of "thinking outside the box". Convergent ...
