A MODEL BASED ON ARAS-G AND AHP METHODS FOR MULTIPLE CRITERIA PRIORITIZING OF HERITAGE VALUE

The paper discusses the meaning and nature of urban cultural heritage, and the available methods for its valuation in the perspective of sustainable city development. From this perspective, decision-making problems of renovation often involve a complex decision-making process in which multiple requirements and conditions have to be taken into consideration simultaneously. In project development it is hardly possible to get exhaustive and accurate information. As a result, the situations occur, the consequences of which can be very damaging to the project. Sometimes the loss is related to symbolic values that the public perceive as disregarded by the project, despite the overall improved conditions. This paper presents the multiple criteria assessment of alternatives of the cultural heritage renovation projects in Vilnius city. The model consists of the following elements: determining attributes set affecting built and human environment renovation; information collection and analysis, decision modeling and solution selection. The main purpose of the model is to improve the condition of the built and human environment through efficient decision making in renovation supported by multiple attribute evaluation. Delphi, AHP and ARAS-G methods, considering different environment factors as well as stakeholders' needs, are applied to solve problem.
