Virtually any enterprise which is relevant to tourism (such as recreation abroad), is interested to have reliable information about the demand for products offered, particularly with respect to the projected demand for the future. From this figure is entirely dependent on the state of the tourism business, advertising, planning investment opportunities for business expansion, etc. In order to develop infrastructure, expand the transport network, services, build new hotels, amusement parks, it is necessary to have information about the most probable how many tourists come to this place, how much time they spend here, what are their needs, how much money they spend here. Information on tourism demand and evidence-based forecasts can be reliable basis for making long-term tourism development program, which provides the maximum socio-economic effect with minimal losses.

One of the problems of effective management of tourism business is to bring supply into line with existing demand, so there was no excess or deficiency. The difficulty lies in the fact that the transient tourist product, it is impossible to store, store for future use, so unused supply in the form of unsold hotel rooms or trips cause irreparable. Things are going well, where the real demand ensures the achievement of planned load factors and hotel vehicles. This shows the importance of identifying and forecasting the demand for all companies and individuals involved in providing tourism services. Real demand is measured by indicators such as: – the number of arrivals – number of nights or turodney – the average cost per visitor. The potential demand is measured by the number of visitors possible.
