The paper addresses an intelligent simulation approach to tourism and cultural heritage management. Emergent information technologies, modelling approaches and simulation paradigms provide new capabilities for intelligent and interoperable management of tourism and cultural heritage. Nowadays mobile applications for tourism organisation at heritage sites have become quite popular. Smart mobile applications with embedded simulation capabilities can significantly increase intelligence of managerial decisions and improve the quality of customer services. The concept of a mobile application that for a particular tourist place suggests objects to be visited preferably at the moment is introduced in this paper. A simulation-based case study for intelligent management of pedestrian tourist flows at heritage sites is given. An agent-based modelling paradigm is applied to simulate tourists’ behaviour and analyse operational solutions. Post-experimental analysis to explore behaviour of the developed simulation model is performed.
