Optimization models and techniques under uncertainty are playing a relevant role in many business and research applications. The challenges arising in these contexts are often formulated and solved in a framework of Stochastic Optimization. Services are expanding rapidly throughout the world and important classes of decision problems (e.g., resource allocation, workforce management, services location, inventory management, routing and scheduling) are commonly faced by many service providers in different domains. Stochastic Optimization includes a variety of powerful modelling and algorithmic approaches and can offer a valuable support to tackle complex problems in the Service Science.  
ECSO 2017 will be held on September 20-22, 2017, in Rome, Italy. It is the 2nd edition of a stream of triennial conferences organized by the EURO Working Group on Stochastic Optimization (EWGSO) - formerly the EURO Working Group on Stochastic Programming-. The previous edition was held in Paris in 2014 (September 24-26), organized by Abdel Lisser.

The scope of this EWGSO Conference ECSO-2017 “Stochastic Optimization in Service Science” is to discuss the latest trends and challenges in Stochastic Optimization and its advanced applications to services.  
The conference aims to bring together the leading researchers in Stochastic Optimization, practitioners in the field, PhD students, clients and users. Participants are welcome from academia and industry, media and institutions concerned with data uncertainty as well as decision making involving stochastic applications in services. Representatives of these areas of practice will get in contact with leading experts of Stochastic Optimization, and the state-of-the-art of research, and learn about new academic solutions and tools suitable for future applications. Participants from academia will be informed about the challenges faced by practitioners and about their unsolved needs and concerns when adopting Stochastic Optimization methods and models.  
Finally, it is expected the participation of a considerable number of PhD students. Young researchers starting or developing their research related to Stochastic Optimization are encouraged to present their work for discussion and take part in the sessions and plenary lectures on the challenging topics of Stochastic Optimization theory and practice, held during the conference. 
The conference will be held at the Engineering School of Roma Tre University in Rome, Italy. Rome is the capital of Italy and it is the country's largest and most populated city. It is one of the most important hubs in Italy and hosts several leading universities. The 2nd edition of ECSO will accept contributions related to Stochastic Optimization theory and applications, with particular emphasis on Service Science. 
The program of the conference consists of plenary sessions, and parallel organized (i.e., invited and contributed) sessions.
