FACT: A new neural network-based clustering algorithm for group technology

This paper introduces the Fuzzy art with Add Clustering Technique (FACT) algorithm which is a new neural network-based clustering technique. FACT can be trained to cluster machines and parts for cellular manufacturing under a multiple objective environment. The existing GT clustering techniques are minaly concerned with grouping parts and machines based on only one criterion which is the parts’ processing routes. The FACT algorithm is able to consider several similarity criteria such as parts’ processing routes, design requirements of parts, processing time on each machine, and demand for each part. The FACT algorithm, which is based on the fuzzy ART neural network, is powerful enough to solve problems of real-world sized complexity.
