Abstract
Excerpt: This special issue of Decision Support Systems accepted eight research papers out of twenty nine submissions on important and highly relevant topics addressing e-commerce, innovation, social media, service system design, and supply chain design research areas. At least two scientific reviewers and the editors reviewed each submission. Most of the accepted papers went through two to four rounds of revisions to meet the reviewers' requirements and the high quality standard of the journal. We thank all the reviewers for their help and the authors for their support and quality contributions. Most of the papers in this special issue creatively use novel information models, or new technologies to address some fundamental business issues.
