TECHNOLOGICAL GOODNESS INDEX FOR FURNITURE DESIGN
Keywords:
technological quality assessment, standardization, dimensional optimization, technological indexes in the furniture industry, Product Data Management systemAbstract
Managing an ever-growing number of components is technologically challenging for furniture manufacturers; therefore, minimizing produced components' "dimensional entropy" is necessary. A novel method to assess how dimensional decisions made during furniture design influence the growth of the components' dimensional entropy is proposed in the article. The dimensions of each newly designed element were compared to a specific set of preferred dimensions. This approach facilitates furniture design using dimensionally unified components. The Jaccard coefficient for fuzzy sets was employed to achieve it. The obtained similarity score was called the "technological goodness index" (TGI) of furniture.This index can be calculated at three levels: for a group of furniture items, a single piece, and the furniture components. Using the TGI in the CAD, manufacturers gain insight into their newly designed products' "technological" quality. By analyzing this data, designers can create furniture that boosts production efficiency, promotes productivity, and cost savings.
