Cross Dock Scheduling: Classification, Literature Review and Research Agenda
Boysen, Nils; Fliedner, Malte - Wirtschaftswissenschaftliche Fakultät, … - 2009
merged to full truck loads in order to realize economies in transportation. In this context, the truck scheduling problem … and on-time deliveries. Due to its high real-world significance, several truck scheduling procedures have been introduced …, the paper on hand introduces a classification of deterministic truck scheduling. With the help of this classification …

The revealed preference approach to collective consumption behavior: testing, recovery and welfare analysis
CHERCHYE, Laurens; ROCK, Bram DE; VERMEULEN, Frederic - Centrum voor Economische Studiën, Faculteit Economie … - 2007
We extend the nonparametric ‘revealed preference’ methodology for analyzing collective consumption behavior (with consumption externalities and public consumption), to render it useful for empirical applications that deal with welfare-related questions. First, we provide a nonparametric...

The Shapes of Polyhedra
Scarf, Herbert E.; Kannan, R.; Lovasz, Laszlo - Cowles Foundation for Research in Economics, Yale University - 1988
Let A be a real matrix of size (n+d+1)xn. We assume that all n x n submatrices of A are non-singular and define the condition number C = C(A) to be the ratio of the largest n x n subdeterminant of A to the smallest in absolute value. In addition we assume that there is a positive vector pi such...

Mathematical Programming and Economic Theory
Scarf, Herbert E. - Cowles Foundation for Research in Economics, Yale University - 1989
The paper discusses the analogy between economic institutions and algorithms for the solution of mathematical programming problems. The simplex method for solving linear programs can be interpreted as a search for market prices that equilibrate the demand for factors of production with their...

The Generalized Basis Reduction Algorithm
Scarf, Herbert E.; Lovasz, Laszlo - Cowles Foundation for Research in Economics, Yale University - 1990
Let F(x) be a convex function defined in R^{n}), which is symmetric about the origin and homogeneous of degree 1, and let L be the lattice of integers Z^{n}. A definition of a reduced basis, b^{1},...,b^{n}, of the lattice with respect to the distance function F is presented, and we describe an...

Shortest Integer Vectors
Scarf, Herbert E.; Shallcross, David F. - Cowles Foundation for Research in Economics, Yale University - 1991
Let A be a fixed integer matrix of size m by n and consider all b for which the body is full dimensional. We examine the set of shortest non-zero integral vectors with respect to the family of norms. We show that the number of such shortest vectors is polynomial in the bit size of A, for fixed...

Neighborhood Complexes and Generating Functions for Affine Semigroups
Scarf, Herbert E.; Woods, Kevin M. - Cowles Foundation for Research in Economics, Yale University - 2004
Given a_{1}; a_{2},...a_{n} in Z^{d}, we examine the set, G, of all nonnegative integer combinations of these ai. In particular, we examine the generating function f(z) = Sum_{b in G}z^{b}. We prove that one can write this generating function as a rational function using the neighborhood complex...
