Covering arrays have been studied for their applications to drug screening and software and hardware testing. In this paper, we model the problem as a constraint program. Our proposed models exploit non-binary (global) constraints, redundant modelling, channelling constraints, and symmetry breaking constraints. Our initial experiments show that with our best integrated model, we are able to eit...

Quark-meson duality for two-point functions of vector and axial-vector QCD currents is investigated in the large-Nc approximation. We find that the joint constraints of duality and chiral symmetry imply degeneracy of excited vector and axial-vector mesons in the large-Nc limit. We compare model-independent constraints with expectations based on the VenezianoLovelace-Shapiro string model. Severa...

We consider the problem of maximizing revenue when selling k items to a single buyer with known valuation distributions. Hart and Nisan [2] raised some questions on the approximation of maximizing revenue from selling a set of items by selling each item separately or all in a bundle. In this work we show that for a single, additive buyer whose valuations for for the items are distributed accord...

T paper analyzes optimal selling strategies of a monopolist facing forward-looking patient unit-demand bidders in a sequential auction market. Such a seller faces a fundamental choice between two selling regimes: adaptive selling that involves learning about remaining demand from early prices, and commitment selling that forgoes such learning and makes all selling decisions in the beginning of ...

This study discusses salespersons' emotional intelligence, one of the key abilities necessary to meet customers' needs effectively, and express positive emotions in frequent interactions with customer. Emotional intelligence refers to self-controllability and social ability emphasizing pro-social aspect and understanding of others. This study investigates how salespersons' emotional intelligenc...

Purpose – This study aims to assess the impact of a JIT-selling strategy on organizational structure by generally replicating the previous work of Germain et al. Design/methodology/approach – In contrast to the sample population of logistics managers surveyed by Germain et al. this research draws on data from manufacturing executives with marketing responsibilities. More importantly, a major li...
