Simulation metamodelling with neural networks: an experimental investigation
Artificial neural networks are often proposed as an alternative approach for formalizing various quantitative and qualitative aspects of complex systems. This paper examines the robustness of using neural networks as a ...
A general theory on spectral properties of state-homogeneous finite-state quasi-birth-death processes
In this paper a spectral theory pertaining to Quasi-Birth–Death Processes (QBDs) is presented. The QBD, which is a generalization of the birth–death process, is a powerful tool that can be utilized in modeling many stochastic ...
On the single-assignment p-hub center problem
We study the computational aspects of the single-assignment p-hub center problem on the basis of a basic model and a new model. The new model's performance is substantially better in CPU time than different linearizations ...
The single-assignment hub covering problem: models and linearizations
(Palgrave Macmillan Ltd., 2003)
We study the hub covering problem which, so far, has remained one of the unstudied hub location problems in the literature. We give a combinatorial and a new integer programming formulation of the hub covering problem ...
Designing a road network for hazardous materials shipments
We consider the problem of designating hazardous materials routes in and through a major population center. Initially, we restrict our attention to a minimally connected network (a tree) where we can predict accurately the ...
