Observations on the application and development of parametric-programming techniques

Abstract A parametric program may use rules and algorithms to define the relationships between dimensions and elements of designs, and it may thus generate variants of a design. Programs currently in use have technical limitations in their ability to handle time-varying and imprecise data, the search for suitable existing designs and their maintainability. The paper suggests how these and other limitations can be overcome to widen the field of application of parametric programs.
