Similar to other MDE scenarios, these transformations have been implemented via multiple transformation steps interconnected in an automated model transformation chain. In this short paper, we use the MDPE case study to demonstrate reasons for decomposing model transformations and discuss disadvantages in terms of execution costs. Based on these experiences, we propose, as an input for future research, an architecture to optimize decomposed model transformation chains.enText/Conference Paper1617-5468
