The most important problem today is how to protect and preserve the historic heritage. With the spread of adaptive reuse as a solution for sustainable protection, industrial architectural heritage has been prioritized as flexible spaces capable of accommodating new uses. In this article, the MultiCriteria Decision Making method with the AHP approach is introduced as a basis for choosing the high and best use of the Carpet factory of Kerman. Combining the AHP method with the MCDM approach can solve the complexity of problems that contain subjective and conflicting criteria by organising them into a hierarchy that identifies goals, criteria, sub-criterial, and alternatives and determines each item's value pairwise. This research aims to analyze theories, relevant international documents, and develop a theoretical framework by adopting a multi-criteria decision-making (MCDM) approach and analyzing data through the Analytical Hierarchy Process (AHP) in ExpertChoice software. considering that the most important factor in achieving integrated conservation and development approaches in historical cities is attracting people's participation and adopting a bottom-up approach in the decision-making process.so because of The alternatives and criteria were organized using a semi-structured interview with the local community and quarter needs. To include experts, a semi-structured questionnaire based on a theoretical framework was compiled and its data was processed with software. The goal is to determine the best use among three proposed options for the Kerman Carpet Company factory, which is a part of Kerman's Pahlavi-era industrial heritage and was one of the major centers for carpet production and export in the southeast of the country. The findings of this research shows that the use of "creative industries" can improve the social, cultural, and economic levels of the neighborhood, enhance creativity in the city and region, and ensure the protection of both the tangible and intangible values of the complex.
