Comparative Analysis of RAM Value Correction Method Based on the Evaluation of the Weapon system Staff

Purpose: This paper presents a correction method to improve the accuracy of the estimated RAM value in the proposed stage of the new weapon system using the SEM(structural equation model).Methods: The staff in the field of operation, maintenance, and support of the weapon system evaluates the time required by each field, evaluates the correction between the main variables by using the SEM, and suggests how to use it in estimating the RAM value. Excel and Amos programs are used for descriptive statistical analysis and SEM.Results: A comparative analysis on the calibration method using MIL-HDBK-17 and SEM for RAM value correction is proposed to improve the accuracy of RAM value.Conclusion: RAM data correction items were verified through data verification for the difference of evaluation results according to the staffs in each field, and direct and mediating effects on variables affecting RAM value estimation were verified using SEM.
