EVALUATING COMPLICATEDNESS IN MECHANICAL DESIGN
Journal Title: Journal of Machine Construction and Maintenance - Year 2018, Vol 109, Issue 2
Abstract
Few researchers recognize the differences between complexity and complicatedness. Recent research indicates that complexity is an inherent property of the system, and is not a negative attribute. Complicatedness is a design property that can be reduced starting at the design stage. Design solutions for complex systems can be complicated or simple. This study explores the current definitions of complexity and complicatedness. It is concluded that the complicatedness of mechanical design depends on the complexity of design properties such as number of parts and interfaces, manufacturing processes, and assembly. A model for evaluating complicatedness is derived based on these parameters. The derived complicatedness model is the only model to consider both functional and physical attributes as parameters. This model is the main goal of this research. We analyse three sets of functionally equivalent systems to verify the model. We then validate the model with an experiment in which experienced engineers review the designs of these systems and grade the complicatedness of each. Analysis of the results yields a perfect fit for two of the sets. For the third set, in which industrial design is embedded in the mechanical components, the results are inconclusive.
