To address the limitations of traditional localization rate calculation methods in assessing the autonomy and controllability of inkjet printing equipment, the work aims to propose a more comprehensive and objective integrated evaluation method to accurately characterize the autonomy and controllability of the equipment. Based on the Analytic Hierarchy Process (AHP), a hierarchical structure model comprising objective, criterion, and alternative layers was constructed. By incorporating multidimensional evaluation indicators such as functional importance, technical criticality, judgment matrices were developed through expert scoring to determine component weights, followed by consistency checks. Finally, the quantity-based and value-based localization rates using a weighted approach were integrated to form a comprehensive weighted localization rate indicator. In a case study of a specific inkjet printing equipment model, the traditional method yielded a quantity localization rate of 99.14% and a value localization rate of 86.58%, whereas the AHP-based comprehensive localization rate was 76.95%. The results demonstrated that the improved method more accurately reflected the significant impact of core components, such as printheads, on overall autonomy and controllability, effectively mitigating the overestimation caused by an inflated quantity indicator. The proposed AHP-based comprehensive weighted localization rate evaluation method provides a more objective measure of autonomy and controllability for inkjet printing equipment. The research findings help identify the importance of core components such as printheads in the overall autonomy and controllability of the equipment, provide a decision-making basis for subsequent technological breakthroughs and resource allocation, promote industrial security in the inkjet printing equipment manufacturing industry, and can also serve as one of the references for user selection.
