This dissertation aims at identifying appropriate methodologies for planning for the Innovation Park for People Service at Baixada Fluminense. This park, which is part of an Ibero-American network, was conceived to generate social changes in the region where it operates, improving the quality of life and social welfare, by transferring knowledge, technology and innovation and creating companies focused on the development of products and services to reduce social classes’ disparities. The method of case study and action-research is adopted and theories about the planning of complex systems and adaptive planning are examined, considering the specificities of Science and Technology Parks and Innovation Parks. The study focuses on the understanding of park planning problems, identifies the key issues to be considered during this process, characterizes the park as an active adaptive complex system, and suggests methodologies for improving its planning process.
