This book constitutes the thoroughly refereed post-conference proceedings of the 15th
International Conference on Membrane Computing CMC 2014 held in Prague Czech Republic in
August 2014. The 19 revised selected papers presented together with 5 invited lectures were
carefully reviewed and selected from 24 papers presented at the conference. In addition two
papers selected from the 22 papers presented at the regional version of CMC the Asian
Conference on Membrane Computing ACMC 2014 held in Coimbatore India are included. The
papers cover a wide range of topics in the area of membrane computing which is an area of
