Sensitivity analysis to plan meliorative actions on a cultural heritage asset evaluated through a multicriteria decision making method

This paper proposes a strategy to increase the value of any asset relevant to cultural heritage, measured through a multicriteria decision making method. The value of any object can be defined on the basis of its fitness to fulfil specified objectives, its significance to the people who own or use it, its potential to produce revenues, and a host of additional criteria depending on its nature. The multiple criteria on which the analysis is based are often of subjective nature, relying on judgements issued by several experts, stakeholders and decision makers. It is thus important to assess the sensitivity of the result to possible perturbations of the data. Here we propose to exploit the sensitivity analysis to identify a set of suitable lines of intervention to improve the value of the asset.
