Assessment the feasibility of sustainable tourism in urban environments employing the cumulative linear model

摘要

Creating the sustainable tourism industry depends on achieving appropriate infrastructures which are directed at economic, social, and environmental purposes. A question is posed here: "How can we identify the development towards the sustainability of tourism?" In fact, a big obstacle in assessing this issue is lack of a calculation way with a mathematical logic to report about the sustainability. To do so, a list of human needs of the tourists is suggested for gathering a set of the tourism indices. These indices are extracted from the completed questionnaires by the tourists, the study of the tourists' need assessment, and also employment of Delphi technique and the categorization of needs of these people and the coordination of these indices with the sustainable development factors. To assess the amount of the sustainable tourism achievement and make the determined assessment indices operational, the cumulative linear model is employed. In this method, the urban sustainability results from assessing two distinct amounts. One of these amounts is the degree of satisfying each index, and the other is the relative importance of the index relative to other indices.
