In this paper the following facility location problem in a mixed planar-network space is considered: We assume that traveling along a given network is faster than traveling within the plane according to the Euclidean distance. A pair of points (A <Subscript> i </Subscript>,A <Subscript> j </Subscript>) is called covered if the time to...</subscript></subscript>

We present a branch-and-cut algorithm to solve the single commodity uncapacitated fixed charge network flow problem, which includes the Steiner tree problem, uncapacitated lot-sizing problems, and the fixed charge transportation problem as special cases. The cuts used are simple dicut...

In this paper we examine a variant of the uncapacitated lot-sizing model of Wagner-Whitin that includes fixed charges on the stocks. Such a model is natural in a production environment where stocking is a complex operation. The problem can also be seen as a single source uncapacitated fixed...

This paper illustrates and compares the results of the application of two different approaches--non-parametric and artificial neural network techniques--for the rapid cost estimation of turbine components. This technique is a simple and automatic way for the estimation of the cost of a piece...
