The Use of Sensitivity Analysis in Handling Conflicting Design Requirements
Computer aided design systems often hold information about a design in parametric form. This means that constraints can be specified between the parameters and optimisation of designs with respect to these can take place. When the number of degrees of freedom becomes large or when design goals are in conflict, there is a need for the human designer to interact. The paper discusses the use of a constraint modelling system and shows how sensitivity information can be provided to guide the human user. This helps to identify the key design parameters and the structure of the design problem.
