Seongsu Park, Sangjin Lee · Journal of Applied Reliability · 2019
Purpose: Studies have shown that the factors of up days of equipment, usage, age, cumulative usage, and operational location can influence the failure rate of equipment. The objectives of this study are to identify and prioritize the factors that influence the failure rate of K1A1 tanks under Korean operational circumstances.BRMethods: This study formulates a multiple regression model to achieve the objectives described above. We collected field operational data of 146 K1A1 tanks by using DELIIS (Defense Logistics Integrated Information System) over a period of three years from April 2009 to March 2012.BRResults: Yearly usage of equipment is the most significant factor influencing the failure rate of K1A1 tanks. The next most significant factors are cumulative usage and age. Operational location of equipment is not significant factor in this study, as it was in a previous study.BRConclusion: The methodology developed in this study may be applied to other equipment to explain their failure rates under diverse operating scenarios.
