Abstract

Small to medium manufacturing companies are coming to realise the increasing importance of performing\nfast and accurate cost estimates at the early stages of projects to address customers’ requests for\nquotation. However, they cannot afford the implementation of a knowledge-based cost estimating software.\nThis paper explains the development and validation of a consistent methodology for the cost estimating of\nmanufactured parts (focused on pistons) based on the design features. The research enabled the\nidentification of the sources of variability in cost estimates, and the main one is the lack of formal procedures\nfor the cost estimates in manufacturing SMEs. Finally, a software prototype was developed that reduces the\nvariability in the cost estimates by defining a formal procedure, following the most appropriate cost\nestimating techniques.
