A feature complexity index

Abstract

An index is presented for quantifying the geometric complexity of a three-dimensional solid model. This provides a measure by which components may be compared one with another in relation to their relative complexity. The index is alphanumeric and readily computable. Such an index can be of use in the field of feature recognition as a means to determine how efficiently one algorithm handles components of varying complexity compared to another such algorithm.The performance of the authors' own feature recognition algorithm is tested against components of differing complexity as determined by the index.

Micro-injection moulding of polymer microfluidic devices

“…A number of studies have suggested techniques to evaluate the complexity of injection-moulded shapes with respect to replication and demoulding (Little et al 1998;Rosen et al 1992).…”

Measuring complexity for building projects: a Delphi study

“…Many empirical studies in the construction field reflect that project complexity would affect the project duration, cost, and quality (Gidado and Millar, 1992;Raymond, 1995;Walker and Sidwell, 1996;Chan and Kumaraswamy, 1997;Chan, 1998;Dissanayaka and Kumaraswamy, 1999;Tatikonda and Rosenthal, 2000;Nassar and Hegab, 2006). It is has been widely accepted that the project complexity should be objectively measured in order to provide continuous feedback to help control the process of project development (Baccarini, 1996;Little et al, 1997;Calinescu et al, 2000;Sinha et al, 2006;Nassar and Hegab, 2006;Leung, 2007).…”

A real-time assessment of the ship design complexity

“…Various researchers have recognised the importance of objectively measuring complexity, as an aid to addressing the cause of such engineering and management related problems [4,5,6]. Our first objective is to decide what complexity is.…”
