Dear Colleagues, we are pleased to inform you about the Conference Eurocast 2019 – 30 years 17th International Conference on Computer Aided Systems Theory Museo Elder de la Ciencia y la Tecnología. Las Palmas de Gran Canaria, Spain 17-22 February, 2019 http://eurocast2019.fulp.ulpgc.es/ Among the planned activities we point out the following workshop, that we hope you find of interest. An extended two pages abstract must be sent by the Abstract Submission form before November 15, 2018. *Stochastic Models and Applications to Natural, Social and Technical Systems (Nobile, Di Crescenzo)* The Workshop deals with theory and applications of probability in the modeling of random phenomena in the natural sciences, social sciences and technology, focusing on mathematical theory, analytical, algorithmic, experimental approaches and computational methods. Practical applications of stochastic models to diverse areas such as biology, computer science, telecommunications modeling, inventories, reliability, queueing theory, optimization and operations research are very welcome as well. Attention is given also to probabilistic methods in data science and related areas, and their applications to the treatment of big data. Many greetings, Amelia Nobile and Antonio Di Crescenzo
