Systems thinking on complex tourism systems.

The complexity of tourism systems requires holistic and accurate decision-making. Systems thinking became a mode of thinking in the last century; it is a point of view that approaches tourism and its challenges as a whole. Through systems methodology, methods of modeling and simulation, we present a survey of tourism systems as a very important branch of welfare through feedback loops and a simulation model. Such a model usually consists of a causal loop diagram. Simulation becomes a multidisciplinary approach to solving problems of complex systems. This paper demonstrates that simulation results are evaluated with the group decision-making support system and with expert systems. Conclusions derived from a model understanding and model simulation give optimal results to the decision-makers. Thus, systems thinking principles lead towards thinking of cooperation and co-creation in tourism and life in general.
