Growing Hierarchical Self-Organizing Map Computation for Clustering in Cellular Manufacturing

This article focuses on approach that provides visualization of machine–part clustering in cellular manufacturing system based on sequence of operation. We propose a novel cell formation approach, namely the growing hierarchical self-organizing map (GHSOM), for dealing with 14 benchmark problems from literature. The performance of the proposed algorithm is tested with the problem data sets and the results are compared using the group technology efficiency (GTE) and computational time with the existing traditional clustering algorithms. It is found that the proposed algorithm resulted in an increase in GTE in most of the problem data sets, and the outputs of cell formation are either superior or same as existing methods. The outputs of the experiments conducted in this research lead us to the conclusion that the GHSOM is a promising alternative cell formation algorithm owing to its adaptive architecture and the ability to expose the hierarchical structure of data.

Applying improved median linkage heuristic for cell formation problem considering binary data

The crucial problem in cellular manufacturing system (CMS) is to identify the machine cells and corresponding part families to form the production cells. This article portrays a novel approach based on median linkage clustering (MLC) algorithm to form the production cells. The projected technique is demonstrated in two portions. Firstly, the MLC procedure and Nei and Li’s similarity coefficient method are incorporated to obtain the machine cells. Thereafter, a modified part assignment technique is recommended to form the corresponding part-families. The proposed technique is shown to outperform the other published methodologies and produced improved solutions for the test datasets.

Technological Impact in Designing Equipment for Polyethylene Scrap Reprocessing

This explorative article endeavors to identify sectors originating polyethylene products with a substantial repository of recyclable packaging substances and proposes a mechanized appliance which could salvage that ductile packaging scrap and regenerate closely similar product by means of an exotic lamination mechanism. The agenda is to eliminate the scrap which is otherwise to be ragged or ignited in an cremator by pertaining expenditure. Crushing and igniting do not propose any scope to the society and ravage the survival of populace by yielding obnoxious and calumnious flatulencies. However clean technology approach could be adopted to improve social sustainment. The aspiration of this study is to foster an effective mechanized appliance which transform the discarded substances into adaptable goods employing additional lamination mechanism with low investment. The aforesaid arrangement will laminate the scrap foil which is not procurable in the form of reel. This one-on-one lamination mechanism could be far-reaching which eventually reprocess flexible packaging substances and metamorphose into less expensive impermeable and persistent laminas which subsequently deliver several propositions of commonality.
