Integration of Fuzzy Set Theory and Neutrosophic Sets for Qualitative and Quantitative Analysis in Inclusive Service to Native Communities of Ucayali

This research focuses on the examination of public records and their potential to deliver inclusive service to the native populations of Ucayali, a key difficulty in the administration of public services in varied and culturally rich areas. The study tackles a gap in the current literature, where standard techniques do not effectively examine how transparency and sufficiency of services influence inclusive service quality. Using methodologies based on neutrosophic set theory, the research presents a novel way to examine the efficacy and accessibility of public registry services in a particular cultural setting. The findings reveal that the combination of Management Transparency (TG) and Service Adequacy (ADS) has a considerable beneficial influence on Inclusive Service Quality (CSI). This research underlines the necessity of tackling both aspects concurrently to enhance service quality. The contribution of the study is twofold: first, it advances theoretical knowledge by integrating advanced methods for evaluating public services in multicultural contexts; Second, it provides concrete practical recommendations, such as administrative simplification, cultural training of staff, and infrastructure improvement, that can be implemented to make public registry services more accessible and effective for the native communities of Ucayali.
