System Approach to Modelling of Complex Systems with Special Regards to Inter-Organisational Systems

The similarities and differences among methodologies and models of complex systems will be discussed from a general point of view. A hierarchical formal concept will be used to explain the systems approach method in modelling of complex systems. The methodology will be applied to a tourism system, which possesses the typical property of global and local organisation. A problem will be studied through multicriteria decision making, representing a good example of an anticipatory system that enables a tourists to make a right decision.
