A Grouping Genetic Algorithm for the Order Batching Problem in Distribution Warehouses

Koch, Sören; Wäscher, Gerhard - Fakultät für Wirtschaftswissenschaft, … - 2011

Order picking is a warehouse function that deals with the retrieval of articles from their storage locations in order to satisfy certain customer demands. Combining several single customer orders into one (more substantial) picking order can increase the efficiency of warehouse operations. The...

Group-Level Exploration and Exploitation: A Computer Simulation-Based Analysis

Kunz, Jennifer - In: Journal of Artificial Societies and Social Simulation 14 (2011) 4, pp. 18-18

Organisational research has studied the tension between exploration and exploitation for years. In essence, this body of research agrees on the necessity of a balance between explora-tive and exploitative processes to prevent an organisation from falling into a learning trap. Thus, to enhance...

Two Challenges in Simulating the Social Processes of Science

Chattoe-Brown, Edmund - In: Journal of Artificial Societies and Social Simulation 14 (2011) 4, pp. 1-1

This note discusses two challenges to simulating the social process of science. The first is developing an adequately rich representation of the underlying Data Generation Process which scientific progress can \"learn\". The second is how to get effective data on what, in broad terms, the...
