Alcove path model for
We construct a model for using the alcove path model of Lenart
and Postnikov. We show that the continuous limit of our model recovers a dual
version of the Littelmann path model for given by Li and Zhang.
Furthermore, we consider the dual version of the alcove path model and obtain
analogous results for the dual model, where the continuous limit gives the Li
and Zhang model.Comment: 19 pages, 7 figures; improvements from comments, added more figure
Critical resonance in the non-intersecting lattice path model
We study the phase transition in the honeycomb dimer model (equivalently,
monotone non-intersecting lattice path model). At the critical point the system
has a strong long-range dependence; in particular, periodic boundary conditions
give rise to a ``resonance'' phenomenon, where the partition function and other
properties of the system depend sensitively on the shape of the domain.Comment: 28 pages, 6 figures. v4 has changes suggested by refere
Study on k-shortest paths with behavioral impedance domain from the intermodal public transportation system perspective
Behavioral impedance domain consists of a theory on route planning for pedestrians, within which constraint management is considered. The goal of this paper is to present the k-shortest path model using the behavioral impedance approach. After the mathematical model building, optimization problem and resolution problem by a behavioral impedance algorithm, it is discussed how behavioral impedance cost function is embedded in the k-shortest path model. From the pedestrian's route planning perspective, the behavioral impedance cost function could be used to calculate best subjective paths in the objective way.Postprint (published version
Linking business analytics to decision making effectiveness: a path model analysis
While business analytics is being increasingly used to gain data-driven insights to support decision making, little research exists regarding the mechanism through which business analytics can be used to improve decision-making effectiveness (DME) at the organizational level. Drawing on the information processing view and contingency theory, this paper develops a research model linking business analytics to organizational DME. The research model is tested using structural equation modeling based on 740 responses collected from U.K. businesses. The key findings demonstrate that business analytics, through the mediation of a data-driven environment, positively influences information processing capability, which in turn has a positive effect on DME. The findings also demonstrate that the paths from business analytics to DME have no statistical differences between large and medium companies, but some differences between manufacturing and professional service industries. Our findings contribute to the business analytics literature by providing useful insights into business analytics applications and the facilitation of data-driven decision making. They also contribute to manager's knowledge and understanding by demonstrating how business analytics should be implemented to improve DM
Littelmann paths and brownian paths
We study some path transformations related to Littelmann path model and their
applications to representation theory and Brownian motion in a Weyl chamber.Comment: 30 pages, 1 figur
