Design method for cost-effectively realizing high variety products

Managing Variety in Configure-to-Order Products - An Operational Method -

Companies producing customized products tend to increase the variety of their product portfolio, in order to fulfill the demand of their customers and align their strategies with those of competitors. However, the profitability of product families may vary greatly. The purpose of this paper is to develop an operational method to analyze profitability of Configure-To-Order (CTO) products. The op...

How to Collect High-Quality Data Cost-Effectively

Adaptive Method of Realizing

The natural gradient learning method is known to have ideal performances for on-line training of multilayer perceptrons. It avoids plateaus which give rise to slow convergence of the backpropagation method. It is Fisher eecient whereas the conventional method is not. However, for implementing the method, it is necessary to calculate the Fisher information matrix and its inverse, which is practi...

Effectively Realizing the Inferred Message of an Information Graphic

Information graphics, such as bar charts and line graphs, that appear in popular media generally have a message that they are intended to convey. We have developed a Bayesian network that analyzes the communicative signals in an information graphic and produces a logical representation of the graphic’s intended message. However, the output produced by the Bayesian network is deficient for produ...

Polytopal complexes realizing products of graphs

When is the Cartesian product of two graphs the graph of a polytope, of a cellular sphere, or even of a combinatorial manifold? In this note, we determine all 3-polytopal complexes whose graph is the Cartesian product of a 3-cycle by a Petersen graph. Through this specific example, we showcase certain techniques which seem relevant to enumerate all polytopal complexes realizing a given product....
