Are COMPETants more competent for problem solving? The case of a multiple objective transportation problem

Hartl, Richard F.; Doerner, Karl; Reimann, Marc - 2001

In this paper we propose a multi-colony Ant System, where the colonies solve a multi-objective optimization problem concerned with goods transportation.

A new rank based version of the Ant System : a computational study

Bullnheimer, Bernd; Hartl, Richard F.; Strauss, Christine - Institut für Informationsverarbeitung und -wirtschaft … - 1997

The ant system is a new meta-heuristic for hard combinatorial optimization problems. It is a population-based approach that uses exploitation of positive feedback as well as greedy search. It was first proposed for tackling the well known Traveling Salesman Problem (TSP), but has been also...

Network Formation and Coordination Games

Berninghaus, Siegfried K.; Vogt, Bodo - 2003

A population of players is considered in which each player may select his neighbors in order to play a 2 × 2 coordination game with each of them. We analyze how the payoﬀs in the underlying coordination game eﬀect the resulting equilibrium neighborhood resp. network structure.

Performance Implications of Economic and Network Analytic Concepts in the German Motion Picture Industry

Ehrmann, Thomas; Dormann, Julian; Meiseberg, Brinja

This study offers a new framework for organizing a motion picture in such a way thatchances for box-office success are enhanced. We combine and expand two strands of researchfor the moviemaking industry: the economic approach and the social network perspective.Specifically, we integrate the...

One Step Beyond : Evaluating the capacity, risks, structures and processes of the Welsh Construction Industry

Clifton, Nicholas C.; David, Rhys; Pickernell, David; … - Centre for Advanced Studies <Cardiff>; Institute of …; … - 2006

It is argued that construction is an important sector of the Welsh economy in terms of employment, wages and growth. Key competence and capacity issues have arisen, however, due to large contracting firms concentrating on core activities and subcontracting peripheral activities to Small...
