Exploiting the service engineering methodology to reengineer Bergamo's bike sharing product service system

Many cities worldwide are struggling to reduce pollution and to maintain an effective and agile transportation system. Among the many available policies and green solutions, bike sharing programs are emerging as a cost effective and sustainable way to expand the portfolio of transit options, promoting the use of alternative transportation among citizens. However, it is still not clear how to design and consequently improve such a complex system. In this paper, the authors analyze the bike sharing system as a Product Service System (PSS) and explore the applicability of the Service Engineering Methodology (SEEM) to re-engineer and improve the Bergamo bike sharing system (BiGi). First, the paper presents an analysis of the current BiGi system offer; then, possible improvements and solutions are identified through the adoption of the Service Requirement Tree method. Finally, the improvements are proposed and discussed.
