In response to market pressures resulting in increased competition, product proliferation and greater customization, rms in many industries have adopted modern technologies to provide operational exibility on several dimensions. In this paper, we consider the role of product mix exibility, de ned as the ability to produce a variety of products, in an environment characterized by multiple produc...

The purpose of the traffic assignment problem is to obtain a traffic flow pattern given a set of origindestination travel demands and flow dependent link performance functions of a road network. In the general case, the traffic assignment problem can be formulated as a variational inequality, and several algorithms have been devised for its efficient solution. In this work we propose a new appr...

In the present study, a comprehensive and systematic strategy was described to evaluate the performance of several three-way calibration methods on a bio-analytical problem. Parallel factor analysis (PARAFAC), alternating trilinear decomposition (ATLD), self-weighted alternating trilinear decomposition (SWATLD), alternating penalty trilinear decomposition (APTLD) and unfolded partial least squa...

spectral decomposition or time-frequency representation (tfr) is a powerful tool for analyzing time varying nature of seismic data. mapping of a one dimensional seismic time trace to a two dimensional function of time and frequency reveals some characteristics of seismic signals that are not available in only time or frequency representations. this approach has been widely used in seismic explo...

We present a novel data mining approach based on decomposition. In order to analyze a given dataset, the method decomposes it to a hierarclay of smaller and less complex datasets that can be analyzed independently. The method is experimentally evaluated on a real-world housing loans allocation dataset, showing that the decomposition can (1) discover meaningful intermediate concepts, (2) decompo...

Ulrich Faigle asked whether this has an immediate combinatorial interpretation in the following sense: Is it always possible to partition the lattice of subspaces of GF (q) into two intervals of length n− 1 and (qn−1 − 1) intervals of length n− 2, for n ≥ 2? We show that such an interval decomposition of the lattice of subspaces of a finite-dimensional vector space exists if and only if there e...

Qualitative reasoning has been widely applied in the analysis of complex networks, but the loss of quantitative information easily result in reasoning conflict. In this article, we adopt a hierarchical decomposition strategy of the network, and present a general framework of qualitative graphical inference based on enhanced multi-level knowledge fusion so as to avoid reasoning conflict. The fra...
