We have a great pleasure to announce the XVII International Workshop on Beam Dynamics and Optimization (BDO 2014) which will be held together with International Vacuum Electron Sources Conference (IVESC 2014) and will take place in St. Petersburg, Russia from June 30 to July 4, 2014. The series of workshops on Beam Dynamics and Optimization started in 1994. Since that, 16 workshops were held. The workshop took place mostly at Saint-Petersburg (Russia), but also in Saratov, Dubna (Russia) and in St. Petersburg (Florida, USA). In years 2004 and 2005 the BDO workshops were included as separate sections into the 8th International Computational Accelerator Physics Conference (ICAP 2004), and the International Conference "Stability and Control Processes (SCP 2005)", respectively. It should be noticed that the workshop has already developed into a full scale conference with more than 100 participants every time. Nevertheless, we are keeping the traditional and well-recognized name "BDO Workshop". Objectives and Scope Traditionally the objective of the Workshop is to bring together mathematicians, physicists and engineers to present and discuss recent developments in the area of mathematical control methods, modelling and optimization and theory and design of charged particle beams and plasma, parallel and distributed computing in accelerator physics.
