SIM stands for Samenwerking Innovatieve Mainport [Innovative Main Port Alliance].
SIM is an initiative of a number of parties from the aviation sector and knowledge institutions aimed at positioning Schiphol as an innovative European main port.
The partners in SIM are Schiphol Group, KLM, TU Delft [Delft University of Technology], TNO [Netherlands Organisation for Applied Scientific Research] and the NLR [National Aerospace Laboratory].
The airport is an international hub that links the Netherlands with important economic centres across the world via a global aviation network, making the Netherlands a highly attractive international business location. The businesses located at Schiphol itself as well as those in the surrounding area make the main port the most important source and hub of employment in the Randstad conurbation. Furthermore, the careful integration of the airport into and with the surrounding area plays an important role in the development of the main port.
